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

Do not switch off P537!
The occurrence of a fault can significantly shorten the
service life of the device, or even destroy it.
4.1 Overcurrent measurement
"Overcurrent measurement"
P537 (pulse current switch-off) was reached 3x within 50 ms
(only possible if P112 and P536 are disabled)
• FI is overloaded
• Drive sluggish, insufficiently sized,
• Ramps (P102/P103) too steep → Increase ramp time
• Check motor data (P201 … P209)
4.5 Overcurrent / short circuit in
the brake rectifier
Overcurrent / short circuit in the
brake rectifier
• Electromechanical brake defective
• Electromechanical brake connected with
impermissible electrical data
 Check the connection data

5.0
Overvoltage Ud
Link circuit voltage too high
• Increase deceleration time (P103)
• Possibly set shutdown mode (P108) with delay (not
for lifting equipment)
• Extend the quick stop time (P426)
• Speed fluctuation (for example due to high inertia
loads)  if necessary set the <U/f characteristic
curve (P211, P212)
FIs with brake chopper:
• Dissipate energy feedback with a braking resistor
• Check the function of the braking resistor (cable
break)
• Resistance of connected braking resistor too high

8.0 Parameter loss
(maximum EEPROM value
exceeded)
Error in EEPROM data
• Software version of the stored data set not
compatible with the software version of the FI.
NOTE: Faulty parameters are automatically reloaded
(default data).
• EMC interferences (see also E020)
8.1 Inverter type incorrect
• EEPROM faulty
