Servo control
4.5 Torque setpoint limitation
Example: Torque limits with or without offset
The signals selected via p1522 and p1523 include the torque limits parameterized via p1520
and p1521.
Figure 4-7
The hatched area in the example shows the permissible torque range.
Activating the torque limits
1. Select the source for torque limiting via the parameters.
2. Specify the torque limiting mode via the control word.
3. If required, make the following settings:
– Select and activate additional limitations.
– Set the torque offset.
Examples
