t overcurrent limit a.c. VFD: I
2
t limit has triggered, e.g. > 1.5 x I
n
for 60 s (also
note P504)
• Continuous overload at VFD output
• Possible encoder fault (resolution, defect,
connection)
3.1 Chopper overtemperature I

t Brake chopper: I
2
t limit has activated, 1.5 times values
reached for 60 s (please also pay attention to P554, if
present, and P555, P556, P557)
• Avoid overcurrent in brake resistance
3.2 IGBT overcurrent
125% monitoring
Derating (output reduction)
• 125% overcurrent for 50 ms
• Brake chopper current too high
• For fan drives: enable flying start circuit (P520)
3.3 IGBT overcurrent fast
150% monitoring
Derating (output reduction)
• 150% overcurrent
• Brake chopper current too high

E004 4.0 Overcurrent module Error signal from module (short duration)
• Short circuit or ground fault at VFD output
• Motor cable is too long
• Use external output choke
• Braking resistor faulty or resistance too low

Do not switch off P537!
The occurrence of a fault can significantly shorten the
service life of the VFD or even destroy it.
4.1 Overcurrent measurem
"Overcurrent measurement"
P537 (pulse current switch-off) was reached 3x within 50 ms
(only possible if P112 and P536 are disabled)
• VFD is overloaded
• Drive sluggish, insufficiently sized,
• Ramps (P102/P103) too steep -> Increase ramp time
• Check motor data (P201 … P209)

E005
5.0
Overvoltage Ud
DC link voltage too high
• Increase deceleration time (P103)
• If necessary, set switch-off mode (P108) with delay
(not with lifting equipment)
• Extend emergency stop time (P426)
• Fluctuating speed (e.g. due to high centrifugal
masses), adjust U/f characteristic curve if
necessary (P211, P212)
Devices with brake chopper:
• Reduce energy return using a braking resistor
• Check the function of the connected braking resistor
(broken cable)
• Resistance value of connected braking resistor too
high
5.1
Mains overvoltage
Line voltage is too high
• See technical data ( Section 7)
