The values of the axis are displayed.
Meaning
The difference between the position setpoint and the actual position value of the
active measuring system 1 or 2.
Unit: mm, inches or degrees
The difference between the position setpoint at the position controller input and
the actual position value of the active measuring system 1 or 2.
Unit: mm, inches or degrees
The actual contour deviation is displayed with this value (variations of the
following error caused by equalization operations on the speed controller due to
load changes).
The contour deviation results from the difference between an actual position pre-
calculated from the position setpoint and the actual position value of active
measuring system 1 or 2.
Unit: mm, inches or degrees
The servo gain factor in the display is calculated by the NC according to the
following equation:
Velocity setpoint = setpoint currently being output to the axis/spindle.
Here, it is displayed whether measuring system 1 or 2 is active.
