WARNING
UNEXPECTED MOVEMENT
An inappropriate setting for the torque values can result in unexpected
movements of the application and destruction of the motor.
• Make sure this will not cause any damage.
• Do not continue with the test if there is anyone or any obstacle
in the hazardous zone.
Failure to comply with these precautions will result in
death, serious injury or equipment damage.
This tab can be used to set the limit values for various parameters.

Setting the various torque parameters: When the application torque exceeds the torque "C
NOMINAL
", the motor
can provide torque up to the value "C
MAX
" for the maximum duration "
t
MAX
". Thereafter, if the application
torque is still higher than "C
NOMINAL
", the motor torque is limited to the value "C
NOMINAL
" until the application
torque falls back below this value.
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).
