Please use ordering number 132B0111.2 Mechanical Installation VLT ® Micro Drive FC 51 Operating Instructions233.1How to Connect3.1.1Electrical Installation in GeneralNB!All cabling must comply with national and local regulations on cable cross-sections and ambient temperature. Copper conductors required, (60-75° C) recommended.Table 3.1: Tightening of terminals.3.1.2FusesBranch circuit protection:In order to protect the installation against electrical and fire hazard, all branch circuits in an installation, switch gear, machines etc., must be short-circuited and overcurrent protected according to national/international regulations.Short circuit protection:Danfoss recommends using the fuses mentioned in the following tables to protect service personnel or other equipment in case of an internal failure in the unit or short-circuit on DC-link. The frequency converter provides full short circuit protection in case of a short-circuit on the motor or brake output.a circuit capable of supplying a maximum of 100,000 A rms (symmetrical), 480 V maximum.Overcurrent protection:Provide overload protection to avoid overheating of the cables in the installation. Overcurrent protection must always be carried out according to national regulations. Fuses must be designed for protection in a circuit capable of supplying a maximum of 100,000 A rms (symmetrical), 480 V maximum.Non UL compliance:If UL/cUL is not to be complied with, Danfoss recommends using the fuses mentioned in the below table, which will ensure compliance with EN50178/IEC61800-5-1:In case of malfunction, not following the fuse recommendation may result in damage to the frequency converter.VLT ® Micro Drive FC 51 Operating Instructions 3 Electrical Installation3Table 3.3: Fuses3.1.3EMC-Correct InstallationFollowing these guidelines is advised, where compliance with EN 61000-6-3/4, EN 55011 or EN 61800-3 First environment is required. If the installation is in EN 61800-3 Second environment , then it is acceptable to deviate from these guidelines. It is however not recommended.Good engineering practice to ensure EMC-correct electrical installation:•Use only braided screened/armoured motor cables and control cables.The screen should provide a minimum coverage of 80%.The screen material must be metal, not limited to but typically copper, aluminium, steel or lead. There are no special requirements for the mains cable.•Installations using rigid metal conduits are not required to use screened cable, but the motor cable must be installed in conduit separate from the control and mains cables. Full connection of the conduit from the drive to the motor is required. The EMC performance of flexible conduits varies a lot and information from the manufacturer must be obtained.•Connect the screen/armour/conduit to earth at both ends for motor cables and control cables.•Avoid terminating the screen/armour with twisted ends (pigtails). Such a termination increases the high frequency impedance of the screen,which reduces its effectiveness at high frequencies. Use low impedance cable clamps or glands instead.•Ensure good electrical contact between the de-coupling plate and the metal chassis of the frequency converter, see Instruction MI.02.BX.YY.•Avoid using unscreened/unarmoured motor or control cables inside cabinets housing the drive(s), where possible.3.2Mains Connection3.2.1Connecting to MainsStep 1: First mount earth cable.Step 2: Mount wires in terminals L1/L, L2 and L3/N and tighten.Illustration 3.1: Mounting of earth cable and mains wires.3 Electrical Installation VLT ® Micro Drive FC 51 Operating Instructions3For 3-phase connection, connect wires to all three terminals.For single-phase connection, connect wires to terminals L1/L and L3/N.Illustration 3.2: Three-phase and single-phase wire connections.3.3Motor Connection3.3.1How to Connect the MotorSee the chapter Specifications for correct dimensioning of motor cable cross-section and length.•Use a shielded/armored motor cable to comply with EMC emission specifications, and connect this cable to both the decoupling plate and the motor metal.•Keep motor cable as short as possible to reduce the noise level and leakage currents.For further details on mounting of the decoupling plate, please see instruction MI.02.BX.YY.All types of three-phased asynchronous standard motors can be connec-ted to the frequency converter. Normally, small motors are star-connec-ted (230/400 V, Δ/Y). Large motors are delta-connected (400/690 V, Δ/Y). Refer to motor nameplate for correct connection and voltage.Illustration 3.3: Star and delta connections.Step 1: First, mount the earth cable.Step 2: Connect wires to terminals either in star or delta-connection.

It is assumed that the user has full knowledge of the capabilities and limitations of the controller.5.1.3Modbus RTU OverviewRegardless of the type of physical communication networks, the Modbus RTU Overview describes the process a controller uses to request access to another device. This includes i.a. how it will respond to requests from another device, and how errors will be detected and reported. It also establishes a common format for the layout and contents of message fields.During communications over a Modbus RTU network, the protocol determines how each controller will learn its device address, recognise a message addressed to it, determine the kind of action to be taken, and extract any data or other information contained in the message. If a reply is required, the controller will construct the reply message and send it.Controllers communicate using a master-slave technique in which only one device (the master) can initiate transactions (called queries). The other devices (slaves) respond by supplying the requested data to the master, or by taking the action requested in the query.The master can address individual slaves, or can initiate a broadcast message to all slaves. Slaves return a message (called a response) to queries that are addressed to them individually. No responses are returned to broadcast queries from the master. The Modbus RTU protocol establishes the format for the master’s query by placing into it the device (or broadcast) address, a function code defining the requested action, any data to be sent, and an error-checking field. The slave’s response message is also constructed using Modbus protocol. It contains fields confirming the action taken, any data to be returned, and an error-checking field. If an error occurs in receipt of the message, or if the slave is unable to perform the requested action, the slave will construct an error message and send it in response, or a time-out will occur.5.1.4Frequency Converter with Modbus RTUThe frequency converter communicates in Modbus RTU format over the built-in RS-485 interface. Modbus RTU provides access to the Control Word and Bus Reference of the frequency converter.The Control Word allows the Modbus master to control several important functions of the frequency converter:•Start•Stop of the frequency converter in various ways:Coast stop Quick stop DC Brake stop Normal (ramp) stop •Reset after a fault trip•Run at a variety of preset speeds •Run in reverse•Change the active set-up•Control the frequency converter’s built-in relayThe Bus Reference is commonly used for speed control. It is also possible to access the parameters, read their values, and where possible, write values to them. This permits a range of control options, including controlling the setpoint of the frequency converter when its internal PI controller is used.5。

Please use ordering number 132B01112. Mechanical InstallationVLT ® Micro Drive FC 51 Operating Instruc-tions23.3.1.How to Connect3.1.1.Electrical Installation in GeneralNB!All cabling must comply with national and local regulations on cable cross-sections and ambient temperature. Copper conductors required, (60-75° C) recommended.Table 3.1: Tightening of terminals.3.1.2.FusesBranch circuit protection:In order to protect the installation against electrical and fire hazard, all branch circuits in an installation, switch gear, machines etc., must be short-circuited and overcurrent protected according to national/international regulations.Short circuit protection:Danfoss recommends using the fuses mentioned in the following tables to protect service personnel or other equipment in case of an internal failure in the unit or short-circuit on DC-link. The frequency converter provides full short circuit protection in case of a short-circuit on the motor or brake output.Overcurrent protection:Provide overload protection to avoid overheating of the cables in the installation. Overcurrent protection must always be carried out according to national regulations. Fuses must be designed for protection in a circuit capable of supplying a maximum of 100,000 A rms (symmetrical), 480 V maximum.NonUL compliance:If UL/cUL is not to be complied with, Danfoss recommends using the fuses mentioned in table 1.3, which will ensure compliance with EN50178:In case of malfunction, not following the fuse recommendation may result in damage to the frequency converter.VLT ® Micro Drive FC 51 Operating Instruc-tions3. Electrical Installation3Table 3.2: Fuses3.1.3.EMC-Correct InstallationFollowing these guidelines is advised, where compliance with EN 61000-6-3/4, EN 55011 or EN 61800-3 First environment is required. If the installation is in EN 61800-3 Second environment , then it is acceptable to deviate from these guidelines. It is however not recommended.Good engineering practice to ensure EMC-correct electrical installation:•Use only braided screened/armoured motor cables and control cables.The screen should provide a minimum coverage of 80%.The screen material must be metal, not limited to but typically copper, aluminium, steel or lead. There are no special requirements for the mains cable.•Installations using rigid metal conduits are not required to use screened cable, but the motor cable must be installed in conduit separate from the control and mains cables. Full connection of the conduit from the drive to the motor is required. The EMC performance of flexible conduits varies a lot and information from the manufacturer must be obtained.•Connect the screen/armour/conduit to earth at both ends for motor cables and control cables.•Avoid terminating the screen/armour with twisted ends (pigtails). Such a termination increases the high frequency impedance of the screen,which reduces its effectiveness at high frequencies. Use low impedance cable clamps or glands instead.•Ensure good electrical contact between the de-coupling plate and the metal chassis of the frequency converter, see Instruction MI.02.BX.YY •Avoid using unscreened/unarmoured motor or control cables inside cabinets housing the drive(s), where possible.3.

It is assumed that the user has full knowledge of the capabilities and limitations of the controller.5.1.3.Modbus RTU OverviewRegardless of the type of physical communication networks, the Modbus RTU Overview describes the process a controller uses to request access to another device. This includes i.a. how it will respond to requests from another device, and how errors will be detected and reported. It also establishes a common format for the layout and contents of message fields.During communications over a Modbus RTU network, the protocol determines how each controller will learn its device address, recognise a message addressed to it, determine the kind of action to be taken, and extract any data or other information contained in the message. If a reply is required, the controller will construct the reply message and send it.Controllers communicate using a master-slave technique in which only one device (the master) can initiate transactions (called queries). The other devices (slaves) respond by supplying the requested data to the master, or by taking the action requested in the query.The master can address individual slaves, or can initiate a broadcast message to all slaves. Slaves return a message (called a response) to queries that are addressed to them individually. No responses are returned to broadcast queries from the master. The Modbus RTU protocol establishes the format for the master’s query by placing into it the device (or broadcast) address, a function code defining the requested action, any data to be sent, and an error-checking field. The slave’s response message is also constructed using Modbus protocol. It contains fields confirming the action taken, any data to be returned, and an error-checking field. If an error occurs in receipt of the message, or if the slave is unable to perform the requested action, the slave will construct an error message and send it in response, or a time-out will occur.5.1.4.Frequency Converter with Modbus RTUThe frequency converter communicates in Modbus RTU format over the built-in RS-485 interface. Modbus RTU provides access to the Control Word and Bus Reference of the frequency converter.The Control Word allows the Modbus master to control several important functions of the frequency converter:•Start•Stop of the frequency converter in various ways:Coast stop Quick stop DC Brake stop Normal (ramp) stop •Reset after a fault trip•Run at a variety of preset speeds •Run in reverse•Change the active set-up•Control the frequency converter’s two built-in relaysThe Bus Reference is commonly used for speed control. It is also possible to access the parameters, read their values, and where possible, write values to them. This permits a range of control options, including controlling the setpoint of the frequency converter when its internal PID controller is used.55.2.Modbus RTU Message Framing Structure5.2.1.Remote Terminal UnitThe controllers are set up to communicate on the Modbus network using RTU (Remote Terminal Unit) mode, with each 8-bit byte in a message containing two 4-bit hexadecimal characters.The format for each byte is shown below.Start bit Data bit Stop/pari-ty Stop5.2.2.Modbus RTU Message StructureThe transmitting device places a Modbus RTU message into a frame with a known beginning and ending point. This allows receiving devices to begin at the start of the message, read the address portion, determine which device is addressed (or all devices, if the message is broadcast), and to recognise when the message is completed. Partial messages are detected and errors set as a result - or timeouts occur. Characters for transmission must be in hexadecimal 00 to FF format in each field.The frequency converter continuously monitors the network bus, also during “silent” intervals. When the first field (the address field) is received, each frequency converter or device decodes it to determine which device is being addressed. Modbus RTU messages addressed to zero are broadcast messages.No response is permitted for boradcast messages. A typical message frame is shown below.StartAddress Function Data CRC check End T1-T2-T3-T41 byte1 byteN x 1 byte2 bytesT1-T2-T3-T4Table 5.1: Typical Modbus RTU Message Structure5.2.3.Start/Stop FieldMessages start with a silent period of at least 3.5 character intervals. This is implemented as a multiple of character intervals at the selected network baud rate (shown as Start T1-T2-T3-T4). The first field to be transmitted is the device address. Following the last transmitted character, a similar period of at least 3.5 character intervals marks the end of the message. A new message can begin after this period.The entire message frame must be transmitted as a continuous stream. If a silent period of more than 1.5 character intervals occurs before completion of the frame, the receiving device flushes the incomplete message and assumes that the next byte will be the address field of a new message. Similarly,if a new message begins prior to 3.5 character intervals after a previous message, the receiving device will ignore both messages. This will cause a time-out (no response from the slave).5.2.4.Address FieldThe address field of a message frame contains 1 byte. Valid slave device addresses are in the range of 0 - 247 decimal. The individual slave devices are assigned addresses in the range of 1 - 247 (0 is reserved for broadcast mode, which all slaves recognise). A master addresses a slave by placing the slave address in the address field of the message.5。

(完整)fc51恒压供水
丹佛斯变频器FC51是一款高性能变频器，可以控制功率高达22 kW 的风机和水泵,外形小巧功能超强可靠，具有内置SLC（智能逻辑）功能，可以满足各种应用需求。
在水泵应用中，我们经常会接触到恒压控制系统。
丹佛斯FC51变频器自带PI调节功能,能实现恒压供水控制.但是恒压供水系统中还有很多其他功能，例如：休眠功能，我们就可以使用FC51自带的SLC功能来实现。
现在我们来介绍如何运用FC51的SLC逻辑实现恒压供水+休眠功能。
一、休眠功能的要求:在恒压供水控制系统中,为了节省电能和防止水泵频繁启停，要求当泵的速度低至输出频率下限，延时一段时间后变频器自动停止输出，进入休眠状态；然后当压力反馈值低于设定压力下限值时，再自动唤醒变频器。
具体接线图如下：具体参数设置如下：参数号参数名称设定值［代码] 说明1—00 控制方式选择 [3］，闭环过程控制1—60 低速负载补偿 0％1-61 高速负载补偿 0％1—62 滑差补偿 0％3—03 最大参考值 10 （bar）按客户要求3-10.0 预置参考值0 50 ％（对应5 bar）压力设定值3—15 参考来源1 ［0]，无功能3—16 参考来源2 ［0］，无功能4-10 转向［0],仅正向4-12 电机速度下限 20。

The conditions, which are covered in this application note, are:1.Normal situation where the three phases are balanced.2.One phase missing3.Voltage on one phase 3% higher4.Voltage on one phase 3% lower5.Voltage on one phase 3% higher and 3% lower on one of the other phases6.One diode interrupted7.Normal situation but a very stiff main1.1.2Normal Situation where the Three Phases are BalancedThe harmonic spectrum below shows natural harmonic currents generated by a non-linear 3-phase overload (like a frequency converter).The harmonic currents generated by non-linear load are given by the formula:h = p × n ±1where p is the pulse number of the non-linear load (p = 6 for a 3-phase frequency converter), n are positive integer starting from 1 → ∞.Regarding harmonic measurements only harmonics for n ≥50 are of interest.The above formula shows that the natural harmonics are:5, 7, 11, 13, 17, 19, 23, 25, 29, 31, 35, 37, 41, 43, 47, 49...∞Measurements on a real application will often show a minor content of other harmonics as well due to the fact that the mains never is 100% balanced.The magnitude of the individual harmonic depends on the load and on the impedance of the system (cable, transformer, etc.)1 Harmonic Measurements11.1.3One Phase MissingThe graph shows the harmonic spectrum if one of the phases is missing. Beside the natural harmonic content, there is a high content of 3rd harmonic (150 Hz).Multiple of the 3rd harmonic (6., 9., etc.) are also present.1.1.4Voltage on one Phase 3% HigherIf the voltage of one of the phases is higher than the voltage on the other two phases, the harmonic content is the same as if one phase is missing, butthe magnitude of the harmonics are not equal at the three phases.1 Harmonic Measurements11.1.5Voltage on one Phase 3% LowerIf the voltage on one phase is lower than the voltage on the other two phases, the harmonic content is the same as if the voltage is higher on one phase.1.1.6Voltage on one Phase 3% Higher and 3% Lower on one of the Other PhasesAlso under these conditions the harmonic content is the same as for 3rd and 4th.1 Harmonic Measurements11.1.7One Diode InterruptedIf one of the diodes in the rectifier is interrupted, the spectrum shows that all harmonic are present - also even harmonics like 2nd, 4th, etc. are present.1.1.8Normal Situation but a very Stiff MainIf the supply is very stiff (= low supply impedance) the content of the higher harmonics are increasing.1 Harmonic Measurements1。
