Malfunction
Possible Causes
Measure
Brake does not release
No supply voltage available
Check voltage on input terminal
Brake line interrupted
Check brake supply line (check passage)
Line voltage drop on long line
Check the brake voltage
Air gap not okay
Check and adjust air gap
No signal
Brake is not permitted
Use released brake
Brake is worn
Open and clean the brake, check the air gap;
replace the brake if necessary
Incorrect input voltage polarity
Check input voltage and rotate if necessary
Error (continuous
signal)
Brake release is not recognised
Check: Brake is not permitted
Incorrect monitoring module (brake nominal voltage)
Brake drop-out is not detected
Brake is not permitted
Check the function of the monitoring module
Break voltage drop
Check network stability and reinstate it
Unit temperature over 90 °C
Check ambient temperature and, if necessary,
improve the cooling.
Warning
Coil temperature of the brake too high
Check effective coil power, ext. Temperature, friction
power
Wear
Replace rotor
Supply voltage too low
Check and, if necessary, increase supply/output
voltage of the monitoring module; check line length
Clock frequency or P
N
(coil nominal
capacity) too high
Lower clock frequency or P
N
(coil nominal capacity)
Unit temperature over 85 °C
Check ambient temperature. Check clock frequency
and P
N
.
