Operating Modes
Servo control
Activating the torque limits
1. Use parameters to select the torque limitation source.
2. Use a control word to specify the torque limitation mode.
3. The following can also be carried out if necessary:
– Select and activate additional limitations.
– Set the torque offset.
Examples
S Travel to fixed stop (see Section 3.1.15)
S Tension control for continuous goods conveyors and winders
