Torque proving
The Torque proving function ensures that the drive is able to produce torque before it
releases the brake and starts the elevator operation. For this, the function performs
an electrical elevator system check.
Before opening the brake, the function compares the calculated actual torque of the
drive with a reference torque (parameter
TORQ PROVING REF). If the torque
proving is not successful, that is, the actual torque does not exceed the reference
value during a proving delay (parameter
TRQ PROV FLT DLY), the function
prevents the brake from opening, and the drive trips on fault TORQUE PROVE.
Torque proving can be selected to be performed at every start or at start after defined
time period of standby (>30min stby, >1 hr stby, >90 min stby, >2 hr stby).
