Type Message
F RFID read error (RFIR)
NFC communication interrupted 1. Connect and disconnect mains.
2. Repeat action.
3. If the error occurs again, please contact
the Lenze Service.
F RFID write error (RFIW)
F RFID data CRC invalid (PS02) NFC communication interrupted 1. Load default setting.
2. Connect and disconnect mains.
3. Rewrite parameter set.
F RFID data version invalid (PS04) Incompatible software version Update Lenze App or EASY Starter.
F Missing mains phase (SU02) A mains phase of a three−phase supply has
failed. Reliable detection from an
utilisation > 50 % rated motor power.
¯ Check mains connection.
¯ Check fuses.
F DC bus overvoltage (OU) DC−bus voltage too high ¯ Increase deceleration ramp.
¯ Reduce speed for great regenerative
loads.
¯ Use brake resistor.
W Electronics warning temperature (OH4) Lacking or insufficient cooling.
Drive close to being disconnected due to
overtemperature (OH1)
¯ Check cooling.
¯ Clean cooling ribs.
F Electronics overtemperature (OH1) Ambient temperature too high. Ambient temperature must be in the
permissible range.
