6. Measure the DC voltage at the brake:
-
The measured DC voltage after the over-excitation time (see bridge/half-wave rectifier,
must correspond to the holding voltage (see table 5). A deviation of ±10 % is permissible.
7. Check the air gap “s
L
”.
-
It must be zero and the rotor must rotate freely.
8. Check the switching status of the micro-switch (see table 6).
9. Open the switching contact for the brake.
-
The brake is applied.
10. Check the switching status of the micro-switch (see table 6).
11. Switch off DC voltage for the brake.
12. Screw the bridges onto the motor terminals.
13. If necessary, remove the neutral conductor from the neutral point (step 2).
The preparations for commissioning are completed.
