Cause
• Remedy
3.0 Inverter overcurrent
I
2
t limit has triggered, e.g. > 1.5 x I
n
for 60s (please also note
P504)
• Continuous overload at inverter output
3.1 Chopper overcurrent
U
2
t-limit for brake chopper has triggered
(please also see P554, P555, P556, P557)
• Avoid overcurrent in braking 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)
E003
3.3 Overcurrent IGBT rapid
monitoring 150%
De-rating (power reduction)
• 150% overcurrent
• Brake chopper current too high

Section 8.5
4.0 Overcurrent module
Error signal from module (short duration)
• Short circuit or earthing at FI output
• Use external output choke (motor cable is too long)
E004
4.1 Overcurrent pulse switch-off
P537 (pulse current switch-off) was reached 3x within 50ms
(only possible if P112 and P536 are disabled)
• Fi is overloaded
• Check motor data (P201 … P209)
5.0 Overvoltage link circuit
FI link voltage is too high
• Reduce energy return by means of a braking resistance
• Extend braking time (P103)
• If necessary, set switch-off mode (P108) with delay (not
for lifting equipment)
• Extend emergency stop time (P426)
E005
5.1 Overvoltage mains
Mains voltage is too high
• Please check 380V-20% ... 480V+10%
or 200 ... 240V ± 10%
6.0 Link circuit undervoltage
(charging error) )
E006
6.1 Mains undervoltage
Inverter mains/link voltage too low
• Check mains voltage 380V-20% ... 480V+10%
or 200 ... 240V ± 10%
E007
7.0 Mains phase failure
One of the three mains input phases was or is interrupted.
• Check mains phases 380V-20% ... 480V+10%
or 200 ... 240V ± 10%, possibly too low?
• All three mains phases must be symmetrical.
OFF
NOTE: OFF appears in the display when the three mains phases are uniformly reduced,
i.e. when a normal mains switch off occurs during operation.
