4.5.1. Connecting the holding brake (option)
WARNING
LOSS OF BRAKING FORCE DUE TO WEAR OR HIGH TEMPERATURE
Application of the holding brake while the motor is rotating can cause
rapid wear and loss of braking force.
• Do not use the brake as a service brake.
• Note that an "emergency stop" can also cause wear.
If these precautions are not taken, the result could be death,
serious injury or damage to equipment.
WARNING
UNEXPECTED MOVEMENT
Releasing the holding brake can cause unexpected movement in the
installation.
• Take care that this does not cause any damage.
• Only run tests if there is no person or obstacle inside the danger
zone.
If these precautions are not taken, the result could be death,
serious injury or damage to equipment.
CAUTION
MALFUNCTION OF THE HOLDING BRAKE DUE TO AN INAPPROPRIATE
VOLTAGE
• If the voltage is too low, the holding brake cannot release itself and
that will cause wear.
• If voltages are higher than specified, the holding brake will suffer
excessive heating.
If these precautions are not taken, the result could be injury or
damage to equipment.
A motor with a holding brake requires a suitable control logic which releases the brake when rotational
movement starts and which grips the motor shaft in time when the motor stops.
