0: No measuring system active.
1: Measuring system 1 active.
2: Measuring system 2 active.
The state of measuring system 1 or 2 is output here:
Active - Parked - Passive
The actual position of the axis measured via measuring system 1 or 2.
The position is displayed in the machine coordinate system (no work
offsets or tool offsets taken into account).
Unit: mm, inch or degrees
Specified position transferred from the interpolator to the position control
Unit: mm, inch or degrees
Display of the absolute compensation value for measuring system 1 or
2.
The compensation value consists of the sum of backlash and leadscrew
error compensation for the actual axis position.
Unit: mm, inch or degrees
Display of the compensation value calculated for the current axis posi‐
tion based on the total of the sag and temperature compensations.
Unit: mm, inch or degrees
The pulses supplied by the encoder are evaluated by the NC and dis‐
played.
Unit: %
100% means maximum speed.
Speed setpoint transferred to the drive (= speed setpoint from position
controller and feedforward control).
Unit: %
100% means maximum speed setpoint.
Speed setpoint programmed by the user.
Unit: rpm
For example: Input: S1000; display: 1000 rpm
Display applies to spindles only.
