3.6. Connecting the Holding Brake (Optional)
WARNING
LOSS OF BRAKING FORCE DUE TO WEAR OR HIGH TEMPERATURE
Engaging the holding brake while the motor is running leads to rapid
wear and loss of braking force.
• Do not use the brake as a service brake.
• Note that "emergency stops" can also cause wear.
Failure to comply with these precautions can result in death,
serious injury or damage to equipment.
WARNING
UNEXPECTED MOVEMENT
Releasing the holding brake can result in unexpected movement on
the installation.
• Make sure this cannot cause any damage.
• Do not continue with the test if there is anybody or any obstacle in
the danger zone.
Failure to comply with these precautions can result in death,
serious injury or damage to equipment.
CAUTION
MALFUNCTION OF THE HOLDING BRAKE DUE TO INAPPROPRIATE
VOLTAGE
• If the voltage is too low, the holding brake cannot release, resulting in
wear.
• In the event of voltages higher than the specified value, the holding
brake will be subject to significant overheating.
Failure to comply with these precautions can result in injury or
damage to equipment.
A motor with a holding brake needs a corresponding control logic which releases the holding brake at the
start of the rotation movement, locking the motor shaft in time when the motor stops.
