9.3.3

Checking the air gap

 DANGER

Danger: rotating parts!

The motor must 

not

 run while the air gap is being checked.

1. Measure the air gap s

L

 between the armature plate and the stator near the fastening screws using a

feeler gauge. (Refer to table Rated data for air gap specifications, Page 24 for the values.)

2. Compare the measured air gap to the value for the max. permissible air gap s

Lmax

 . (Refer to table

Rated data for air gap specifications, Page 24 for the values.)

3. Adjust the air gap to s

LN

. (Refer to Adjusting the air gap, Page 75).

9.3.4

Release / voltage

 DANGER

Danger: rotating parts!

The running rotor must not be touched.

 DANGER

There is a risk of injury by electrical shock!

The live connections must not be touched.

1. Check the brake functionality when the drive is running: The armature plate must be tightened and the

rotor must move without residual torque.

2. Measure the DC voltage at the brake.

– Compare the measured voltage to the voltage specified on the name plate. A deviation of up to

10% is permitted.

– When using bridge/half-wave rectifiers: After switching to one-way voltage, the measured DC

voltage may drop to 45% of the voltage specified on the name plate.
