Troubleshooting and fault elimination
Cause
Frequent and too long overload
periods
Motor is thermally overloaded by
x t overload) e.g.
l impermissible continuous
current
l frequent or too long
acceleration processes
Ambient temperature is too high
Heatsink is very dirty
Impermissible high currents or
frequent and too long
acceleration processes
Motor too hot due to
impermissible high currents or
frequent and too long
acceleration processes
No PTC connected
Controller is too hot inside
Motor too hot due to
impermissible high currents or
frequent and too long
acceleration processes
No PTC connected

Fault elimination
Fault messages
Remedy
Check drive dimensioning
l Check drive dimensioning
l Check setting of C0120
Allow controller to cool and provide
for better ventilation
Clean heatsink
l Check drive dimensioning
l Check load, replace
rough−running, defective
bearings, if necessary
Check drive dimensioning
Connect PTC or switch off monitoring
l Reduce controller load
l Improve cooling
l Check fan in the controller
Check drive dimensioning
Connect PTC or switch off monitoring
