6-6. Adjustment of the electromagnetic brake gap
Follow the procedure below to adjust to the appropriate gap (0.5 mm) when the brake gap crosses it, approaching
or even crossing the limit gap (1.0 mm).
(1) Remove the screws and remove the lock washer.
(2) Insert between the solenoid and the brake disc as shown in ‘
Figure 2
’.
(3) Tighten the 4 U-nuts evenly.
(4) Since the thickness of the lock washer is 0.5 mm, when there is no "play" with the lock washer inserted, the
brake gap will be set to 0.5 mm.
(5) Return the U-nut slightly (about 1/6 of a turn) and pull out the lock washer.
* The U-nut is tightened by 1.0 mm with one revolution
(6) Return the lock washer to its original position as shown in ‘
Figure 1’ and tight with the screws.
* Measure the thickness dimension H of the brake wheel, and if it exceeds the value in ‘
Table 3
’, replace it.
