Commissioning and operation
Important notes
DANGER
Danger: rotating parts!
¾
The running rotor must not be touched.
¾
Take structural design measures on your final product and implement organizational
safety rules to ensure that nobody can touch a rotor.
DANGER
There is a risk of injury by electrical shock!
The live connections must not be touched.
7.1
Function checks before initial commissioning
7.1.1
Brake with micro-switch
1. The switching contact for the brake must be open.
2. Remove two bridges from the motor terminals to de-energize the motor.
– Do not switch off the voltage supply to the brake.
NOTICE
If the brake is connected via the neutral point of the motor, this connection
must also be used for connecting the neutral conductor.
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:
– After the over-excitation time (refer to the table Data for bridge/half-wave rectifier type
BEG-561, Page 40), the measured DC voltage must correspond to the holding voltage (refer to As-
signment: Bridge/half-wave rectifier – brake size, Page 39). A deviation of ±10 % is permissible.
7. Check the air gap "s
L
".
8. It must be zero and the rotor must rotate freely.
9. Check the switching status of the micro-switch (siehe to table Switching status of micro-
10. Open the switching contact for the brake.
– The brake is applied.
