Possible causes
NFC communication interrupted
NFC communication interrupted
Incompatible software version
A mains phase of a three-phase
supply has failed. Reliable detection
from an utilization > 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
Motor thermally overloaded
Too frequent and too long braking
processes
Lenze Smart motor without brake
resistor: DC-bus voltage too high
Various
Diagnostics and fault elimination
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 Imax.
• 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.
• Check setting of the I2xt
monitoring function.
• Increase acceleration and
deceleration ramp.
Increase deceleration ramp.
• Reduce regenerative load.
• Use brake resistor.
• Increase deceleration ramp.
Reset error. If the error occurs again
during restart, please contact the
Lenze Service.
