NOTICE
Negative values at r1534 or positive values at r1535 represent a minimum torque for the
other torque directions and can cause the drives to rotate if no counteractive load torque is
generated (see function diagram 5630 in the SINAMICS S120/S150 List Manual).
Example: Torque limits with or without offset
The signals selected via p1522 and p1523 include the torque limits parameterized via p1520
and p1521.
Figure 3-10
Activating the torque limits
1. Use parameters to select the torque limiting source.
2. Use a control word to specify the torque limiting mode.
3. The following can also be carried out if necessary:
Examples
● Travel to fixed stop
● Tension control for continuous goods conveyors and winders
