Fault Possible causes Remedy
Type Message
F RFID read error (RFIR) NFC communicaon interrupted 1. Connect and disconnect mains.
2. Repeat acon.
3. If the error occurs again, please
contact the Lenze Service.
F RFID write error (RFIW)
F RFID data CRC invalid (PS02) NFC communicaon interrupted 1. Load default seng.
2. Connect and disconnect mains.
3. Rewrite parameter set.
F RFID data version invalid (PS04) Incompable soware version Update Lenze App or EASY Starter.
F Missing mains phase (SU02) A mains phase of a three-phase
supply has failed. Reliable detecon
from an ulizaon > 50 % rated
motor power.
•
Check mains connecon.
•
Check fuses.
F DC bus overvoltage (OU) DC-bus voltage too high
•
Increase deceleraon ramp.
•
Reduce speed for great
regenerave loads.
•
Use brake resistor.
W Electronics warning temperature (OH4) Lacking or insucient cooling.
Drive close to being disconnected due
to overtemperature (OH1)
Ambient temperature too high.
•
Check cooling.
•
Clean cooling ribs.
Ambient temperature must be in the
permissible range.
F Electronics overtemperature (OH1)
F Electronics overload (Ixt ) (OC9) The Ixt overload test has been
triggered
•
Motor load too high.
•
Load cycles not complied with.
•
Increase deceleraon ramp.
•
Reduce Imax.
•
Check dimensioning.
F Electronics overcurrent (OC11) Overcurrent limitaon acve
•
Reduce motor load.
•
Increase deceleraon ramp.
F Motor overcurrent (OC7) The maximum current monitoring
funcon has been triggered.
Reduce motor load.
F Motor short circuit (OC1) Short circuit in the motor phases Reset error. If the error occurs again
during restart, please contact the
Lenze Service.
F Motor earth fault (OC2) A motor phase has earth contact
F Motor overload I2xt (OC6) Motor thermally overloaded
•
Reduce motor load.
•
Check seng of the I2xt
monitoring funcon.
•
Increase acceleraon and
deceleraon ramp.
F Brake resistor overload I2xt (OC12) Too frequent and too long braking
processes
Increase deceleraon ramp.
Lenze Smart motor without brake
resistor: DC-bus voltage too high
•
Reduce regenerave load.
•
Use brake resistor.
•
Increase deceleraon ramp.
F Internal error (DH69) Various Reset error. If the error occurs again
during restart, please contact the
Lenze Service.
F Internal error (DF01)
