Remedy Cause Fault PC 1) Keypad
OC5
a
15 Controller overload
during steady−state
operation Frequent and too long overload
periods Check drive dimensioning
OC6
a
16 Motor overload
(I
2 x t overload)
Motor is thermally overloaded by
e.g.
l impermissible continuous
current l Check drive dimensioning
l frequent or too long
acceleration processes l Check setting of C0120
OH
a
50 Heatsink
temperature > +85
°C Ambient temperature is too high Allow controller to cool and provide
for better ventilation
OH
e
− Heatsink
temperature > +80
°C Heatsink is very dirty Clean heatsink
OH
e
− Heatsink
temperature > +80
°C Impermissible high currents or
frequent and too long
acceleration processes l Check drive dimensioning
l Check load, replace
rough−running, defective
bearings, if necessary
OH3
a
53 PTC monitoring
(TRIP)
(display when
C0119 = 1 or 4) Motor too hot due to
impermissible high currents or
frequent and too long
acceleration processes Check drive dimensioning
No PTC connected Connect PTC or switch off monitoring
OH4
a
54 Controller
overtemperature Controller is too hot inside l Reduce controller load
l Improve cooling
l Check fan in the controller
OH51 203 PTC monitoring
(display when
C0119 = 2 or 5) Motor too hot due to
impermissible high currents or
frequent and too long
acceleration processes Check drive dimensioning
No PTC connected Connect PTC or switch off monitoring
