6. Measure the DC voltage at the brake:
– After the over-excitation time (refer to the table ), the measured DC voltage must correspond to the
holding voltage (refer to Assignment: Bridge/half-wave rectifier – brake size). 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-
switch, Page 44).
10. Open the switching contact for the brake.
– The brake is applied.
11. Check the switching status of the micro-switch (siehe to table Switching status of micro-
switch, Page 44).
12. Switch off DC voltage for the brake.
13. Screw the bridges onto the motor terminals.
14. If necessary, remove the neutral conductor from the neutral point (step 2).
