9. Create an Addapt Realtime Screen to monitor A023:IARM SETPT, A003:I ARM PCNT and
A016:ARM ALPHA. Using Realtime Screen, turn on LOC BIT 1 (Run) and slowly increase parameter C037: ALT TRQ STP (Ref) in the positive direction. Monitor parameter A016: ARM ALPHA and observe that firing angle as the ALT TRQ STP value increases. It may be necessary to increase the current limits. You should have a full control range from 120 degrees to 30 degrees firing angle.
10. Change parameter C037: ALT TRQ STP to –10.0 and repeat step 9. Results must be the same as
obtained in step 9. Change C037: ALT TRQ STP to 0.0.
11. Connect SCR gate leads for one Forward Bridge, leave other Bridges disconnected. Note this will not be
possible if using the Bush SCR Firing Adaptor board.
12. Power up the AFM and Bridges. With C037: ALT TRQ STP (Ref) = 0.0, turn on LOC BIT 1 and
slowly increase the value of C037: ALT TRQ STP until you observe pulses on scope. You should span as shown below. As reference is increased, amplitude of pulses will increase. Note there is a 5x gain between the CT burden resistor and the IARM test point.
If 2 pulses are of greater magnitude than the other four, check CT wiring into feedback board as CT’s should be connected in parallel, not series.
If oscilloscope were connected across one of the burden resistors, the waveform should look like the

13. If all pulses observed on scope are negative instead of positive as shown above, reverse all CT polarities.
If the CT leads are difficult to reach, switch the wires for all CTs at J1 of the SCR Firing Adapter.
14. If the voltage waveform observed on scope has some positive segments and some negative segments as
shown in Figure below, verify that all CT’s have their dot facing in the same direction with respect to current flow. Check CT wiring at Feedback board.
15. Increase parameter C037: ALT TRQ STP to 30.0. Verify A023:IARM SETPT = 30.0. Document DVM
reading across armature shunt or on Clamp On Ampmeter. Verify that A003:I ARM PCNT = 30.0. Verify that measured current across armature shunt or Clamp On Ammeter equals 30% of the motors nameplate rating.
16. Turn LOC BIT 1 off and set C037: ALT TRQ STP = 0.0. Power down AFM and all bridges. Disconnect
the SCR Gate leads for the Forward Bridge and connect SCR Gate leads for the Reverse Bridge if applicable.

ARMATURE CURRENT LOOP SELF TUNE
Motors containing series fields should have the series field disconnected or bypassed. Series fields are not typically used with regenerative drives and may
cause self tuning failure if connected. Bypassing the series field should only result
in a 2-5% increase in armature current to make up for the lost torque.
1. Test the Switchbox E-STOP and E-STOP RESET pushbuttons. Verify EMERG STOP OK and DRIVE
READY LEDS on drive are illuminated. Verify parameter D017:ABC ROTATE = ONE BIT. Reverse incoming phase A and C if D017:ABC ROTATE = ZERO BIT. 2. Verify rotor of motor is locked or brake is set. Go to the ACCESS CODES submenu, E006 SELF
TUNE, and press the right arrow key. While someone is watching the motor, use an Addapt Realtime Screen to turn on RUN (LOC BIT 1). The DC contactor should pick up and self tuning of the armature current loop begins.
3. When Self Tune test is complete, drive will fault and display shows “Tune Pass”. Turn off LOC BIT 1
(RUN). Clear the drive fault and FIFO. If Tune Fail is displayed, adjust X049: ARM RESIST or X053: Z-C CORRECT = -1000.0 to be closer to actual values. If ICONT > ILIM faults occur on AFM’s or Panel Drives during self tune test, swap the polarity of Iarm feedback at the BIB and / or verify the CT's are installed (dot) and wired with the same polarity. Repeat step 2.
4. Record the following tuning parameters. Verify parameters have changed from their default values. X044: IARM CONTIN = _______________ (30.0)
X049: ARM RESIST = _______________ (0.01)
X053: Z-C CORRECT = _______________ (-600.0)
X054: IARM PGAIN = _______________ (0.20)
X055: IARM IGAIN = _______________ (0.20)
FIELD LOOP SCALING & TUNING
1. Install a clamp on DC ammeter on one of the motor field wires at the drive TB1 (1)
or (2) for 510 ADC
drives and below or at TB1 (-) or (+) for 540 ADC drives and above. Note ammeter polarity requirements.
3. Reset the drive in ACCESS CODES or by a drive power cycle.
4. Verify that A005: I FLD PCNT = 100.0%. If it is not equal to 100.0, adjust X003: MFLD % SCALE in
DRIVE CALIBRATE as required. Reference ADD-32 Manual Appendix for
MFLD %SCALE adjustment.

Rev: 01/31/06 8
ADDvantage-32 AC to DC Power Converter Software Part Number 694012.V15 and Up Optimized for Blueprint Room Printer
5. Adjust X002: MOTOR IFLD so the ammeter is equal to the motor field nameplate value if the field
windings are connected in series and double the nameplate value if connected in parallel.
6. Observe A006: I FLD AMP and adjust X004: MFLD ASCALE in DRIVE CALIBRATE if required so
that displayed I FLD AMP matches the ammeter. Reference ADD-32 Manual Appendix for MFLD ASCALE adjustment. Document the following scaling parameters:
X002: MOTOR IFLD
X003: MFLD %SCALE
X004: MFLD ASCALE = _______________ = _______________ = _______________ 7. Observe A017:FLD ALPHA from the OPERATE submenu DRIVE ANALOG. If the value is less than
40 degrees, try changing transformer tap to increase Line Volts into Field Supply. You may be able to get a minimal increase in Field Alpha by swapping the incoming 3-phase power at L1 and L3 on drive. Verify that the FLD ALPHA value has increased by some amount.
Vdc = 0.9*Vac*cos(field alpha)
A017:FIELD ALPHA at 100% IFLD PCNT = ___________ Deg
8. Check scaling of any Analog meters for Field Current and / or Field Voltage.
9. If this drive’s motor is to be field weakened, it will be necessary to tune the Field Loop. It is normal to
only tune X066:IFLD PGAIN, leaving X067:IFLD IGAIN at default. PGAIN values of 5.0 or 7.0 are typical. If ADD-32 Field Supply is used along with an external Field Supply (for parallel motor applications), it is important that ADD-32 Field Loop response be tuned to match response of external Field Supply.
Use Addapt Realtime Screen and setup Signal Analyzer to monitor / record A021:IFLD CMD. A005:I FLD PCNT and A013:FLD VOLTS. Setup Signal Analyzer for Analog trigger using Rate = 1 or 1.5. Step change can be achieved by toggling C038:FLD MAX LMT from 75 to 100. Adjust X066:IFLD PGAIN for best response with no overshoot and no instability at steady state.

Reverse the two motor field wires if motor runs backwards. 5. After verifying motor control, stop motor if running uncoupled. Remove and lock out drive power.
Have millwright couple motor to the roll if it was not coupled in step 12 above.
Apply drive power and run motor again at 10% of rated base motor speed. Verify that A012: ARM VOLTS is correct for the present speed and motor armature volt rating. While motor is running at 10% rated speed, verify that A034: SPEED IN 1 displays a positive polarity and the correct value for the motor speed.

C004:RUN SPEED until rated armature volts is displayed in A012: ARM VOLTS. Document the roll speed displayed in A000: FIL SPEED at base motor speed.
A000: FIL SPEED = __________________
7. Have machine operator nip and load the rolls if applicable.
8. Begin speed loop tuning at 75% base process speed. Setup the Addapt Realtime Screen to monitor
various drive parameters. Setup Addapt Signal Analyzer to record A065:SPD REF,
A002:ACT SPEED and A003:I ARM PCNT.
a) Slowly increase C029: SPD P GAIN until instability occurs. Document the P-GAIN value at which
instability first occurs. The FWD BRIDGE ON and REV BRIDGE ON Led’s usually begin to toggle when instability occurs. However, be aware there are times when too much P-GAIN will cause a knee or breakdown on the rising edge of step change long before instability occurs. Decrease the SPD P GAIN until the instability disappears. Turn on LOC BIT 2 to enable step change for about 8 seconds and then turn off. Verify that motor/roll speed increased by the C009:AUX SPD ST1 value, Current Limit Led is off, and that no instability exists. If instability occurs, reduce the SPD P GAIN as required.
Reduce the motor/roll speed to 25% base process speed. Enable the speed step change as above and reduce the SPD P GAIN as required if instability occurs.
b) Return the motor/roll speed to 75% base process speed. Begin increasing the C031: SPD I GAIN by
lowering the value from 8.0 seconds to 7.0 seconds and so on in 1-second increments. Turn on LOC BIT 2 to enable step change after each change to SPD I GAIN and observe the speed response on Signal Analyzer. Adjust the SPD I GAIN as necessary to obtain the quickest speed response with 10% or less overshoot. Check the speed response at 25% and 50% of base process speed. Adjust the SPD I GAIN as required. C029: SPD P GAIN = __________
C031: SPD I GAIN = __________
c) If acceptable speed response cannot be obtained, the problem may be due to a mechanical resonance
frequency limiting the speed loop gains. A notch filter may be required to obtain the desired speed response.
While recording A002: ACT SPEED on Signal Analyzer, increase the C029: SPD P GAIN until the speed goes unstable for 5 seconds and quickly reduce the SPD P GAIN until the motor speed becomes stable. Count the number of speed oscillations (peaks) for a 5-second period of instability. Divide the number of peaks by 5 seconds to compute the notch frequency in HZ. Turn off LOC BIT 1 (Run) and set the following parameters:
C029: SPD P GAIN = C024: NOTCH DEPTH = C025: NOTCH FREQ =
TRW
Rev: 01/31/06 13
ADDvantage-32 AC to DC Power Converter Software Part Number 694012.V15 and Up Optimized for Blueprint Room Printer C026: NOTCH WIDTH = Turn on LOC BIT 1 (run). Repeat steps 8a and 8b above. Adjust the NOTCH DEPTH and NOTCH WIDTH if required to obtain desirable speed response.
d) If acceptable speed response still cannot be achieved, the user may try a LEAD or LAG filter. The
motor should be stopped before entry of either LEAD or LAG values. The LEAD filter can be used when faster speed response is required. To obtain a LEAD filter, the user must make C028: SPEED LEAD smaller than C027: SPEED LAG.
The LAG filter can be used to reduce overshoot at the sacrifice of slower speed response. To obtain a LAG filter, the user must make C027: SPEED LAG smaller than C028: SPEED LEAD. Typical values for a LAG filter is LAG = 20 and LEAD = 80 or 100.
Setting both SPEED LEAD and SPEED LAG = 1.0 prevents the LEAD/LAG filter from affecting the speed loop response. The further the SPEED LEAD and SPEED LAG values are separated from each other, the more effect the filters have on the speed response. Entering LEAD and LAG values will require adjustments to the SPD P GAIN and SPD I GAIN values, so repeat steps 8a and 8b.
Check speed response at 25% and 50% of base process speed.
C028: SPEED LEAD = ___________
C027: SPEED LAG = ___________
e) Inertia compensation (SPD FFWD GN) may be required on machine sections having a large inertia,
such as dryer sections on paper machines. Inertia compensation gives the motor a boost in armature current only during ramping.
If inertia compensation is desired, set up ADDAPT Signal analyzer to record
A002:ACT SPEED and A003: I ARM PCNT. Note the present speed displayed in A000: FIL SPEED and increase C004:RUN SPEED to create a sizable speed increase (ramped). Determine the value for C007: RUN AF RATE.
During the speed change, I ARM PCNT will peak and then drop off when inertia is overcome. The SPD FFWD GN can then be calculated by:
C007: SPD UP RATE
C035: SPD FFWD GN = ______________ Percent

The step response can be implemented using the Realtime Screen by increasing C044: CROSS OVR V by 20 VDC and then decrease back to original value. Verify there is not instability when crossing from the armature range to the field range or at any speed in the field range.
C045: CEMF P GAIN = _______________
C046: CEMF I GAIN = _______________
8. For greater CEMF control accuracy, TABLE #O should be set up. The X values will be entered as
speed in process units and Y values entered as I FLD PCNT divided by 100. The X0 value should always be 0.00 (zero speed) and Y0 = 1.00 (100%).
The X1 value should be entered as your speed at crossover and its corresponding Y1 value = 1.0 (100%). Parameter X15 = your maximum speed. The remaining Y values will be entered as the decimal equivalent of the percent field current (I FLD PCNT。
