VIX AE SERVO DRIVE USER GUIDE 70
Reset (Z)
Issuing a reset will engage the brake, at least momentarily, as the system fails safe.
Subsequently, the following will happen:
•
The brake will remain applied in automatic mode until the drive is re-energised.
•
The brake will be released if the MOTOR command indicates no brake is fitted.
24V Power Failure
A dip in the +24V supply will turn off the drive’s controller, which in turn will apply the brake.
Cycle the 24V supply to re-start the controller.
If you expect this to happen during motion, use dynamic brake control, assuming that a
dynamic brake is fitted.
Drive Fault
You may program application of the brake during a fault routine.
For both automatic brake modes, if a fault generates a controlled stop, the brake is applied
when commanded motion stops, and before the drive is de-energised.
