Fault / Drive Error

What it usually means

Recommended corrective action

Drive stays in “bb” (not-ready) state

24 V *Drive-Enable* or mains still missing – drive only ready-for-power-up, not ready-for-enable

Apply 24 V to the RF/Enable input, verify 230/400 V supply fuses, then issue a Class-1 reset to change status to “Ab” (ready-for-enable)

F208  “Motor-type change detected”

Connected motor’s ID does not match the data set in the drive

Upload the correct MSK040C file, execute **Basic-Load**, then power-cycle the drive

F212  “Encoder signals out of range”

Encoder sine/cosine amplitude too low or noisy (cable, shield or encoder fault)

Inspect/replace encoder cable, check grounding, keep power- and feedback-cables ≥ 100 mm apart

F218  Amplifier heat-sink over-temperature

Cabinet airflow blocked or fan failed – drive shut down

Lower ambient temperature, clean filters, verify fan, add auxiliary ventilation if required

F219  Motor over-temperature shutdown

Motor winding > 155 °C (over-load or failed cooling)

Reduce load-torque/duty cycle, allow cooldown, inspect motor-temperature wiring

F220  Bleeder-resistor over-temperature

Regenerative energy above resistor rating

Lengthen decel ramp, add or up-rate the braking resistor module 

F226  DC-link undervoltage

while enabled

Mains sag or weak DC-bus capacitors

F228  Excessive control deviation

Command ≠ feedback (axis jam or poor tuning)

Check mechanics for binding, reduce acceleration, re-tune position loop (P-gain), redo reference move

F229  Encoder quadrant error

Wrong edge sequence / noisy encoder

Reseat connector, replace cable; if error persists, swap motor encoder

F230  Max. encoder-1 signal frequency exceeded

Axis driven faster than encoder interface rating

Check gearing & speed parameters; fit higher-speed encoder if motion profile demands it

F234  Emergency-Stop active

+24 V removed at E-Stop input – drive decelerated

Trace safety chain, clear E-Stop, restore 24 V, then reset drive

Part number

Continuous torque (Nm, 100 K)

Peak torque (Nm)

Max speed (rpm)
