12.6.5 Machine data for fictitious axes
MD 224* Software limit switch
MD 228* Software limit switch
MD 232* Software limit switch
MD 236* Software limit switch
The software limit switch need not be input if the fictitious working area is outside the real possible working area, as the control always restricts the fictitious software limit switch to the limit switch of the A1R axis (linear axis of transformation).
MD 276* Acceleration
The acceleration value must be calculated in such a way that the real axes of transformation are not overloaded (minimum acceleration value of A1R to A5R).
MD 280* Maximum speed
MD 288* JOG speed
MD 292* Rapid JOG
The speeds can be freely selected, as they are monitored by the control.
MD 304* IPO parameter
MD 360* Operating mode group of the axis
MD 564* Bit 6 Fictitious axes
The axis is declared as a ”fictitious axis”. Fictitious axes have no position control. The MD 200* measuring circuit assignment is therefore meaningless.
MD 564* Bit 7 Axis exists
MD 568* Encoding of the axis name
MD 576* Axis not permitted in channel
12.1.1 Corresponding data
• NC-MD 316* (Reference point pointer for + compensation)
• NC-MD 320* (Reference point pointer for - compensation)
• NC-MD 324* (Distance between 2 leadscrew error compensation points)
• NC-MD 328* (Compensation value)
• NC-MD 344* (Modulo value for rotary axis)
• NC-MD 6000 to 6249 (Leadscrew error compensation points)
Note carefully:
Changes to NC MD data for leadscrew error compensation do not go into effect until after
completion of POWER ON and reference point approach.
