Inverter: I
2
t limit has triggered, e.g. > 1.5 x I
n
for 60s (please
also note P504)
•
Continuous overload at FI output

Brake chopper: I
2
t limit has triggered, 1.5x value attained for
60s (also note P554, if present, as well as P555, P556,
P557)
•
Avoid overload of brake resistance
3.2
Overcurrent IGBT
Monitoring 125%
De-rating (power reduction)
•
125% overcurrent for 50ms
•
brake chopper current too high
•
for fan drives: enable flying start circuit (P520)
3.3
Overcurrent IGBT
Monitoring 150%
De-rating (power reduction)
•
150% overcurrent
•
brake chopper current too high

4.0
Overcurrent, module
Error signal from module (short duration)
•
Short circuit or earthing at FI output
•
Motor cable is too long
•
Use external output choke
•
Brake resistor defective or resistance too low
The occurrence of the error can greatly reduce the
service life of the FI and even cause its destruction.
4.1
Overcurrent measurement
"Overcurrent measurement"
P537 (pulse current switch-off) was reached 3x within 50ms
(only possible if P112 and P536 are disabled)
•
FI is overloaded
•
Drive sluggish, under-dimensioned,
•
Ramps (P102/P103) too steep -> Increase ramp time
•
Check motor data (P201 … P209)

5.0
Overvoltage UZW
Inverter link voltage is too high
•
Extend deceleration time (P103)
•
If necessary, set switch-off mode (P108) with delay
(not for lifting equipment)
•
Extend emergency stop time (P426)
FIs with brake chopper:
•
Reduce energy return by means of a braking
resistance
•
Check the function of the connected brake resistor
(broken cable?)
•
The resistance of the connected brake resistor is too
high
5.1
Mains overvoltage
Mains voltage is too high
