Fault / Drive Error Meaning (Likely Cause) Corrective Action
Motor will not enable 24 V “Drive Enable” missing or mains phase absent Check three-phase supply, verify RF/Enable relay, then reset drive
F2-05 Switching to an un-initialised operating mode One of the four mode parameters S-0-0032 … 35 = 0 Reload valid operating-mode set, clear fault, re-enable
F2-08 Motor-type change detected Connected motor ID ≠ parameter file Upload correct MDD090C dataset, cycle power 
F218 Amplifier heat-sink over-temperature Drive fan failure or cabinet airflow blocked Improve ventilation, clean filters, derate load 
F219 Motor over-temperature Internal thermistor > 155 °C, cooling path obstructed Reduce load, clear cooling channels, allow cooldown
F226 Undervoltage in power section DC-bus dipped below minimum threshold Inspect mains supply, DC fuses & capacitors; correct wiring 
F228 Excessive control deviation Command ↔ feedback error above limit Check couplings/backlash; retune loops; re-reference axis
F229 Encoder 1 quadrant error Feedback signals out of range or noisy Inspect shield/ground, reseat connector, replace encoder
F230 Max. signal frequency of encoder exceeded Axis running faster than encoder limit Verify speed parameters; check gearing & scaling
F221 Motor-temperature monitor defective Thermistor wiring break/short Ohm-test sensor leads; repair cable or replace sensor
