Remedy
● Reset
● Check the working area limit in the part program (G25/G26) or in the setting data.
● Move in the opposite direction (in JOG mode)
2.5 Supplementary conditions
To ensure that the monitoring functions respond correctly, it is important that the correct
values are entered in the following machine data:
General:
● MD31030 LEADSCREW_PITCH (leadscrew pitch)
● Gear ratio (load gearbox):
MD31050 DRIVE_AX_RATIO_DENOM (load gearbox denominator)
MD31060 DRIVE_AX_RATIO_NUMERA (load gearbox numerator)
Gear ratio (encoder), possibly for spindle:
MD31070 DRIVE_ENC_RATIO_DENOM (measuring gearbox denominator)
MD31080 DRIVE_ENC_RATIO_NUMERA (measuring gearbox numerator)
● MD32810 EQUIV_SPEEDCTRL_TIME
(Equivalent time constant speed control loop for feedforward control)
● Encoder resolution
MD31020 ENC_RESOL[0] (encoder pulses per revolution)
The associated machine data are described in Chapter "Velocities, Setpoint/Actual Value
Systems, Closed-Loop Control (G2)"
For analog spindle only:
● Output voltage / output speed relation
MD32260 RATED_VELO (rated motor speed)
MD32250 RATED_OUTVAL (rated output voltage)
