WARNING
VOLTAGE SURGES
During the braking phases, the motor generates voltage surges.
• Check that its voltage surges can be tolerated by the other devices
connected to the same power supply.
• Use an external circuit to limit voltage surges
if the brake is being used intensively.
Failure to comply with these precautions will result in
death, serious injury or equipment damage.
Setting the overvoltage detection threshold parameters: If the voltage at the motor terminals exceeds this
threshold, an error is generated, the motor is stopped and no holding torque is applied (freewheeling).

" Tab Parameters
For all errors affecting motor safety, the action to be taken cannot be configured: in the event of an error, the
motor is stopped and no holding torque is applied (freewheeling).

Procedure for restarting the motor following detection of an error:
-
Eliminate the cause of the fault.
-
Switch to stop mode: disable digital input 1 "On/Off".
-
Switch back to run mode: enable digital input 1 "On/Off".
