Machine parameters for linear axes
1010, 1060, .. Load monitoring for C axis
Evaluation: Load monitoring
„ Start-up time for monitoring [0..1000 ms]: The load monitoring function is not activated if the nominal
acceleration of the spindle exceeds the limit value (limit value = 15% of acceleration ramp / brake ramp).
As soon as nominal acceleration falls below the limit value, the monitoring function is activated after the
start-up time for monitoring has elapsed.
The parameter is only evaluated if “Omit paths of rapid traverse” is active.
„ Number of measured values to be averaged [1..50]: The mean value is calculated from the number of
values to be averaged. This reduces the sensitivity to short-term peak load during monitoring.
„ Maximum torque is not used at present.
„ Reaction delay time P1, P2 [0..1000 ms]: The system reports a limit violation as soon as the delay time
for P1 or P2 (limit torque 1 or 2) has been exceeded.

„ Rapid-traverse speed, C axis: Maximum speed for spindle positioning
1019, 1069, .. General data, C axis
This parameter is evaluated if “pre-positioning” is switched on (“configuration code 1” – MP 18). For
digital drives, pre-positioning is usually not necessary.
„ Pre-positioning of spindle with M14: Angle at which the spindle is positioned before the C axis is
swiveled in.
1020, 1070, .. Angle compensation in C axis: Parameters are entered by the machine tool builder.
1021..1026,
1071..1076, .. Compensation values in C axis: Parameters are entered by the machine tool builder.

Parameters for linear axes
1107, 1157, .. Backlash compensation for linear axis
During each change in direction, the nominal value is corrected by the value entered in the “Backlash
compensation value” option.
„ Type of backlash compensation
„ 0: No backlash compensation
„ 1: During a change in direction, the value of the backlash compensation is added.
