Appendix B Application Notes
Torque Prove
Carefully perform the following steps in the order presented.
1. Enter Torque Prove parameter settings.
Once Torque Prove is activated, the drive is in alarm state.
2. Select the source of position feedback.
3. Set the time to decrease motor torque during Brake Slip test.
4. Set speed deviation.
Increase this setting if the drive faults on F20 [TorqPrv Spd Band].
5. Set speed deviation level.
Increase this setting if the drive faults on F20 [TorqPrv Spd Band].
6. Set brake release time.
Increase or decrease this setting depending on the time that is required to
open the brake.
7. Set brake set time.
Increase or decrease this setting depending on the time that is required to
close the brake.
8. Set allowable brake slip.
Sets the number of motor revolutions the motor is allowed to lower the
load when a brake slip has been detected.
