6.3 Brake torque setting on motors with a.c. brake (BA)
Loosen locking nut (2). Through nut (1) adjust the air gap and restore distance “T” to its minimum
value, as listed in the chart Repeat the operation symmetrically on each stud bolt holding the brake.
When setting is complete tighten nuts (1) and (2) on each stud bolt.
Too wide an air gap may result into noise and vibrations in operation and, in extreme cases,
even prevent the motor from braking.
6.4 Brake torque setting on motors with a.c. brake (BA)
Brake torque can be adjusted steplessly by changing the preload of springs (4) acting on nuts (3).
Braking torque will increase proportionally to the compression of springs (4).
Repeat the operation symmetrically on each stud bolt holding the brake.
