271
Position reference value Specified position transferred from the interpolator to the position
control.
Unit: mm, inch or degrees
compensation value meas.
system 1 or 2
Display of 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
Sag and temperature
compensation
Display of the compensation value calculated for the current axis
position based on the total of the sag and temperature
compensations.?
Unit: mm, inch or degrees
Velocity actual value of active
encoder (only 840Di)
Display of velocity actual value of the currently active encoder.
Velocity setpoint of drive (only
840Di)
Display of velocity setpoint of drive.
Speed actual value The pulses supplied by the encoder are evaluated by the NC and
displayed.
Unit: %
100% means maximum speed.
Speed setpoint Speed setpoint transferred to the drive (= speed setpoint from
position controller and feed forward control).
Unit: %
100% means maximum speed setpoint
Spindle speed setpoint prog. Speed setpoint programmed by the user.
Unit: rpm
e.g.: Input: S1000; display: 1000 rpm
Display applies to spindles only.
Spindle speed setpoint current Current active speed setpoint with correct sign, including calculated
compensation value and any operative speed limitation
(programmed by means of setting or machine data).
Unit: rpm
Display applies to spindles only.
Override The effective correction factor of the feed or spindle correction
switch is displayed.
Unit: %
Position offset for master axis/
spindle actual value
The currently applicable position offset value is displayed here
(relative to the actual value) if such a position offset (angular offset
between master and slave axes) has been programmed for the
"Synchronous spindle" function.
Unit: mm, inches, degrees
