Fault

Cause

Remedy

Rotor is too thin

The brake has not been re-
placed in time

¾

For spring-applied brake Kendrion INTORQ
BFK557-06 ... 12, replace the brake.

Voltage too high

Brake voltage does not match
the rectifier

Adjust rectifier and brake voltage to each other.

Voltage too low

Brake voltage does not match
the rectifier

Adjust rectifier and brake voltage to each other.

Defective rectifier diode

Replace the defective rectifier with a suitable undamaged
one.

AC voltage is not mains
voltage

Fuse is missing or defective

Select a connection with a proper fuse.
