Possible cause
NFC communication interrupted
NFC communication interrupted
Incompatible software version
A mains phase of a three−phase supply has
failed. Reliable detection from an
utilisation > 50 % rated motor power.
DC−bus voltage too high
Lacking or insufficient cooling.
Drive close to being disconnected due to
overtemperature (OH1)
Ambient temperature too high.
The Ixt overload test has been triggered
¯ Motor load too high.
¯ Load cycles not complied with.
Overcurrent limitation active
The maximum current monitoring
function has been triggered.
Short circuit in the motor phases
A motor phase has earth contact

Remedy
1. Connect and disconnect mains.
2. Repeat action.
3. If the error occurs again, please contact
the Lenze Service.
1. Load default setting.
2. Connect and disconnect mains.
3. Rewrite parameter set.
Update Lenze App or EASY Starter.
¯ Check mains connection.
¯ Check fuses.
¯ Increase deceleration ramp.
¯ Reduce speed for great regenerative
loads.
¯ Use brake resistor.
¯ Check cooling.
¯ Clean cooling ribs.
Ambient temperature must be in the
permissible range.
¯ Increase deceleration ramp.
¯ Reduce I .
max
¯ Check dimensioning.
¯ Reduce motor load.
¯ Increase deceleration ramp.
Reduce motor load.
Reset error. If the error occurs again during
restart, please contact the Lenze Service.
¯ Reduce motor load.
