Assembly and installation
6.4.6 Electromagnetic brake
The Pallet Drive is delivered with an installed electromagnetic brake (if it does not feature a 24V DC brake). The
rectifier is an accessory part and must be ordered separately from the motor.
Connect the rectifier and the brake according to the connection diagrams.
The rectifier has an AC input and a DC output to the brake winding.
DANGER
Risk of injuries when used as safety brake!
When large loads are being held, the motor can unexpectedly rotate in the opposite direction. As a result, loads
may fall down and hit or fatally injure persons.
¾
Do not use the electromagnetic brake as safety brake.
¾
If a safety brake is required, install a suitable additional safety brake system.
NOTICE
Damage of the Pallet Drive and the brake if both are operated simultaneously!
¾
Route the control circuits in such a way that motor and brake do not work against each other.
¾
Consider the response time for applying and releasing the brake (depending on temperature and oil
viscosity, it can amount to 0.4 to 0.6 seconds).
¾
Apply the brake only after the current supply to the motor has been switched off.
¾
Start the motor only after the brake has been released.
The cable should be as short as possible, and the cable cross section should correspond to the national/international
regulations so that the voltage supply at the rectifier does not deviate from the rated voltage by more than ±2%.
The electromagnetic brake is a pure holding brake and should not be used for positioning or braking the motor.
Braking applications should be implemented with a frequency inverter.
