Fault / Drive Error Meaning (Likely Cause) Corrective Action
Motor will not enable 24 V “Drive Enable” contact open or mains phase missing Verify 3-phase supply and the enable relay in the drive, then reset
F2-05  Switching to an un-initialised operating mode Controller was started with empty/invalid mode data Reload correct operating-mode parameters and re-enable the drive
F2-08  Motor-type change detected Stored motor ID does not match connected MDD071C Upload the correct MDD071C dataset and power-cycle
F2-18  Amplifier heat-sink over-temperature Cabinet airflow blocked or fan failed Improve ventilation, clean filters, fit auxiliary fan if required
F2-19  Motor over-temperature Internal thermistor > 155 °C or coolant path obstructed Check load, clear cooling channels, allow cooldown before restart 
F2-26  Undervoltage while drive is enabled Line sag or weak DC-bus capacitors Measure DC-bus, check mains fuses/supply module, correct wiring 
F2-28  Excessive following-error Command vs feedback position deviation too large Inspect mechanical backlash, retune position loop, re-reference axis 
F2-29  Motor-encoder quadrant error Encoder signals noisy, mis-wired or open Inspect shield/ground, reseat connector, replace encoder if faulty
F2-68  Holding-brake release error Brake coil open or air-gap > 0.2 mm Measure 24 V brake supply, reset air-gap, replace worn brake
F2-82  Phase fault (open or shorted stator lead) Broken phase lead or winding short Megger U/V/W leads; repair cable or send motor for rewind
