6.3 Brake with proximity sensor
1. The switching contact for the brake must be open.
2. Remove two bridges from the motor terminals to deenergize the motor.
- Do not switch off the voltage supply to the brake.
- When connecting the rectifier to the neutral point of the motor, the PE conductor must also be con-
nected to this point.
3. Apply DC voltage to the brake.
4. Measure the AC voltage at the motor terminals. The measured level must be zero.
5. Close the switching contact for the brake.
- The brake is released.
6. Measure the DC voltage at the brake:
- Compare the DC voltage with the voltage indicated on the name plate. A deviation of ±10 % is per-
missible.
7. Check the air gap "s
L
".
- It must be zero and the rotor must rotate freely.
8. Check the switching status of the proximity sensor (refer to Table 11).
9. Open the switching contact for the brake.
- The brake is applied.
10. Check the switching status of the proximity sensor (refer to Table 11).
11. Switch off DC voltage for the brake.
12. Screw the bridges onto the motor terminals. Remove additional PE conductor, if necessary.
DANGER
There is a risk of injury by electrical shock!
❚ Electrical connection must only be carried out by skilled personnel!
❚ Only carry out connection work when no voltage is applied (no live parts)! There is a risk of
unintended start-ups or electric shock.
WARNING
Danger: rotating parts!
The brake must be free of residual torque. The motor must not run!
Contact type Connection Brake released Proximity sensor is closed
