Example for SERVOS drive
NC program (user):
- Reduce bipolar torque limit S-0-0092 for all drives involved in the measurement run (e.g. by the NC command #IDENT WR SYN).
- Disable position lag monitoring in the drives:
Ident S-0-0159 = 0 - Start measurement run (G100).
CNC:
- Disable position lag monitoring in the position controller for all axes involved in the measurement run.
- Start of measurement run
- Adoption of the actual position as a measured value as soon as the parameterised conditions for fixed stop detection are fulfilled. On gantry systems, only the master axis is monitored.
- Reduce interpolation to measured value by axis position lag.
- Enable position lag monitoring in the position controller.
NC program (user):
- Move away from fixed stop (e.g. G01).
- Enable position lag monitoring in the drives (set S-0-0159 to original value).
- NC program: Disable torque limiting in the drives (set S-0-0092 to original value).
