E003 3.0 Overcurrent I²t lim
"Overcurrent I²t limit"
Rectifier 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 Overcurrent, chopper
"Overcurrent, chopper I2t"
I
2
t limit for brake chopper has triggered
(Attainment of 1.5x the value for a period of 60s)
(Please also note 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) See also
Section 9.5
3.3 Overcurrent IGBT fast
monitoring 150% De-rating (power reduction)
150% overcurrent
Brake chopper current too high
E004 4.0 Overcurrent module Error signal from module (short duration)
Short-circuit or earthing fault at FI output
Motor cable is too long
Use external output choke
Brake resistor faulty or resistance too low (Section 8)
4.1 Overcurrent measurem
"Overcurrent from overcurrent
measurement"
P537 (pulse current switch-off) was reached 3x within 50ms
(only possible if P112 and P536 are disabled)
FI is overloaded
(Drive unit sluggish, too small,
Ramps (P102/P103) to steep
→ Increase ramp time)
Check motor data (P201 … P209)
E005 5.0 Overvoltage, Ud Frequency inverter link circuit 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 quick stop time (P426)
5.1 Overvoltage mains Mains voltage is too high
Please check 380V- 20% … 480V+10%
or 200 … 240V 
