Checking emergency-off scenarios
DSD is only partially able to check emergency-off scenarios. The user interface and the DSD protocol
display a note.
[7-234] Motor diagram: winder torque (diameter-related)
The Application Tuner may help with the required additional checks.
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.
