7.4 Brake Adjustment

With this gear motor, brake torque can be adjusted within the range of 0 to 50% against the motor rated

torque, with the adjusting bolt. Readjust the brake torque when the braking surface of the disk is

worn and the braking force decreases.



Always set the brake torque for the left and right end trucks at the same value.

a) To adjust brake torque refer to Figure 7-2, Table 7-2, and Table 7-3:

(1) Loosen the lock nut 604.

(2) Brake torque is set by changing the height H of the adjusting bolt 603. The setting range

is within 0 to 50% of the motor’s rated torque.

(3) Tighten the lock nut 604. Do not to allow adjusting bolt 603 to move while tightening the

lock nut.
