E003
3.0
Overcurrent I²t lim.
The current limit (I
2
t) has been exceeded (e.g more than
1.5x the rated current for 60 s).
• Reduce motor load
• Check system for blockage or overload
• Check rotary encoder settings (resolution, defect,
connection)
Further notes:
• Adjust the current limit by changing the pulse frequency
(P504).
E003
3.1
Overcurrent chopper
The current limit (I
2
t) of the brake chopper has been
exceeded (e.g more than 1.5 x rated current for 60 s).
• Avoid overcurrent in braking resistor
• Check braking resistor values (P555, P556, P557 and
P554, if available)
E003
3.2
Overcurrent IGBT
The drive is running above its possible power (125%
overcurrent for 50 ms).
• Reduce motor load
• Check the available inverter power via derating tables
(e.g. increased pulse frequency)
E003
3.3
Overcurrent IGBT fast
The drive is running above its possible power (200%
overcurrent).
• Reduce motor load
• Check available inverter power via derating tables (e.g.
increased pulse frequency)
E003
3.4
Overcurrent chopper
Brake chopper current too high
• Avoid overcurrent in braking resistor
E003
3.7
Power limit input
Input current too high. Continuous overload at FI Input.
Shutdown for 150% overload within 60 s.
• Reduce motor load
• Check system for blockage or overload
Further notes:
• Shortening of the shutdown time due to
– Higher loads
– Frequent overloads
• If the mains voltage is in the lower tolerance range, the
input current increases
E004
4.0
Module overcurrent
Module error
• Short circuit or earth fault at the FI output (motor cable or
motor)
• Check optional braking resistor
Further notes:
• The error also occurs if:
– Size of breaking resistor is wrong
– Motor cable too long
• Do not disconnect (P537)!
• The error may significantly reduce the service life of
the device or even destroy it
