5 Diagnosis/Fault rectification
5.3 Fault signals If a fault occurs in operation it is indicated by a flash code from LED H1
(red) on the inverter module. The code indicates the type of error. If a
KP200 is connected the KP200 indicates the error type as an abbrevia-
tion.

Explanation Cause/Remedy
1x
E-CPU 3 Error in CPU (processor)
Switch power off and back on again. If error reoccurs
notify LUST Service.
2x
E-OFF 1 Undervoltage shut-off
Check power supply. Also occurs briefly in response to
normal power-off.
3x
E-OC 2 Current overload shut-off
Short-circuit, ground fault: Check cabling of connections,
check motor coil, check neutral conductor and grounding
(see also section 3, Installation).
Device setup not correct: Check parameters of control
loops. Check ramp setting.
4x
E-OV 2 Voltage overload shut-off
Voltage overload from mains: Check mains voltage. Restart
device.
Voltage overload resulting from feedback from motor
(regenerative operation): Slow down braking ramps. If not
possible, use a braking resistor.
5x
E-OLM 2 Motor protection shut-off
Motor overloaded (after I x t monitoring): Slow down proc-
ess cycle rate if possible. Check motor dimensioning.
6x
E-OLI 2 Device protection shut-off
Device overloaded: Check dimensioning. Possibly use a
larger device.
7x
E-OTM 2 Motor temperature too high
Motor PTC: Correctly connected?:
Parameter MOPTC (type of motor PTC evaluation) correctly
set?
Motor overloaded? Allow motor to cool down. Check
dimensioning.
8x
E-OTI 2 Inverter overheating
Ambient temperature too high: Improve ventilation in
switch cabinet.
Load too high during driving/braking: Check dimensioning,
possibly use a braking resistor.
