7.22.5 Checking emergency-off scenarios

DSD is only partially able to check emergency-off scenarios. The user interface and the DSD protocol

display a note.

 Note!

The torque required for emergency stop is greater than the drive torque available.

• The torque required for emergency stop is calculated and represented in the diame-

ter-dependent torque diagram of the motor. The calculation is based on the emergen-

cy stop time, a linear motion profile, and a tensile force = 0 N (material crack).

• The thermal utilisation of the drive components is not checked.

• Braking circuits are not dimensioned.
