(TRIP)
impermissible high currents
or frequent and too long
(display when
acceleration processes
C0119 = 1 or 4)
No PTC connected
Controller Controller is too hot inside
overtemperature
PTC monitoring Motor too hot due to

Remedy
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
Check supply voltage
l Increase deceleration times
l For operation with an
external brake resistor:
– Check dimensioning,
connection and supply
cable of the brake resistor
– Increase deceleration
times
Check motor supply cable and
motor for earth fault
(disconnect motor from the
inverter)
Before enabling the controller,
repeat the data transfer or load
the Lenze setting
