5.2 Error messages 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
abbreviation.

Explanation Cause/Remedy
1x E-CPU Collective error
Power-off, remove all control signals, power-on. If error recurs, inform LUST
Service.
1)
2x E-OFF Undervoltage shut-off Check power supply. Also occurs briefly in response to normal power-off.
3x E-OC
Current
overloadshut-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
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
Motor
protectionshut-off
Motor overloaded (after I x t monitoring): Slow down process cycle rate if
possible. Check motor dimensioning.
6x E-OLI
Device safety
shut-off
Device overloaded: Check dimensioning. Possibly use a larger device.
7x E-OTM
Motor temperature
too high
Motor PTC correctly connected?
Parameter MOPTC correctly set(type of motor PTC evaluation)?
Motor overloaded? Allow motor to cool down. Check dimensioning.
8x E-OTI Inverter overheating
Ambient temperature too high: Improve ventilation in switch cabinet.
Load too high during driving/braking: Check dimensioning. Possibly use a
braking resistor.
