Drive display (4-digit)	What the fault means	Quick corrective action
F218 – amplifier over-temp	Power-stage heat-sink passed its shutdown limit and the drive disabled output	Stop the axis, let the unit cool, blow out dust, restore cabinet airflow, replace failed fans
F219 – motor over-temp	Stator PTC/NTC in the connected motor tripped ≈ 155 °C	Lower duty-cycle or load, check ambient (< 40 °C), verify sensor wiring
F220 – bleeder over-temp	Dynamic-brake resistor overheated during regeneration	Lengthen decel ramp, fit larger or fan-cooled resistor, tighten wiring lugs
F221 – motor-temp monitor defective	Temp-sensor circuit open/short; supervision lost	Megger MT+/MT– leads, repair cable, replace sensor if resistance off-spec
F226 – DC-bus undervoltage	Link voltage fell below minimum while enabled	Check mains fuses and input wiring, look for brown-outs, test DC-link capacitors
F228 – excessive deviation	Command-vs-actual position error beyond window S-0-0159	Re-reference axis, tighten couplings, review accel/torque limits, retune loop
F229 – motor encoder quadrant error	Invalid or noisy Hiperface/RSF signals	Inspect/replace feedback cable, route away from power leads, clean connector
F230 – encoder-1 max-freq exceeded	Feedback frequency above interface limit (overspeed or noise)	Check speed command, watch for runaway axis, improve shielding, replace cable
F234 – emergency-stop active	+24 V lost at E-Stop input; drive executed controlled stop	Trace safety loop, reset safety relay, restore 24 V, clear fault
F242 – encoder-2 signal too small	Optional external sin/cos amplitude < 1 V	Re-route or swap cable, verify 5 V/12 V supply, replace faulty encoder
