6.2. Protection
DANGER
PROTECTION
The product has internal protection devices that switch off the
motor power supply when activated. As the motor is no longer
controlled, driving loads can decrease.
• The system manufacturer is responsible for complying with all
the applicable safety rules in the event of product failure.
Failure to comply with these precautions will result in
death or serious injury.
6.2.1. Voltage Protection
The product incorporates protection against voltage surges and undervoltages.
Protection against voltage surges:
The voltage surge threshold can be set in the HMI.
When the supply voltage exceeds the threshold, the product automatically switches to ERROR mode. In
ERROR mode the motor is no longer controlled.
To reset the motor:
-
The supply voltage must be at least 1 V below the threshold value.
-
It is necessary to pass in DISABLE mode then ENABLE mode.
Protection against undervoltages:
The under voltage threshold can be set in the HMI.
When the supply voltage falls below this threshold, the product automatically switches to ERROR mode. In
ERROR mode the motor is no longer controlled.
To reset the motor:
-
The supply voltage must be at least 1V higher than the threshold value
-
It is necessary to pass in DISABLE mode then ENABLE mode.
