18.2.10 Max. torque for emergency stop exceeded
[18-1] Motor diagram: winder torque (diameter-related)
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 diameter-dependent torque
diagram of the motor. The calculation is based on the emergency 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.
Cause Effects Possible remedies
The emergency stop time specified is
too short.
The drive system cannot brake from
max. speed to standstill in the emer-
gency stop time required.
• Increase emergency stop time.
• Dimension drive with a higher
drive torque.
