Symptom / fault code	Likely cause	Corrective action
F219 Motor over-temperature shutdown – drive trips after a few minutes’ run	Ambient > 40 °C, blocked airflow, defective blower, or overload	Check blower rotation & filter; log load cycle vs. rated torque; improve cabinet cooling; allow cool-down then re-enable
F8022 Encoder-1 signals incorrect (red LED on drive)	Feedback cable/EMC noise, cracked Sin/Cos glass, wrong commutation offset	Inspect shield clamp, shorten cable or add ferrites, reload commutation data; replace encoder if error recurs
F230 Max. signal frequency of encoder 1 exceeded at high speed	Commanded speed beyond encoder limit, gearing error, aliasing	Lower speed command or fit higher-line-count encoder; verify gear ratio in drive parameters
F236 Position-feedback deviation too large during rapid moves	Loose coupling, backlash, or wrong position loop gain	Tighten mechanical connection; rerun autotune; increase Kp gradually and test
F8070 +24 V logic supply error (warning then trip)	Control-voltage rail < 21 V or > 30 V	Measure at X31; check PSU sizing & wiring; replace supply if unstable
F8025 Over-voltage in power section when decelerating	Braking resistor open/undersized or regen ramp too steep	Meter DC-bus; test resistor; lower S-0-0044 decel ramp or add larger bleeder
F8060 Over-current in power section immediately on enable	Phase-to-phase short, jammed load, or peak torque demand > Ipeak	Megger motor & cable; free mechanics; reduce S-0-0092 torque limit and retest
F8057 Device overload shutdown after long cycle	Continuous RMS torque exceeds nameplate; fan clogged	Compare duty cycle to S1 rating; clean fan; up-size motor if duty unchanged
F822 Encoder-1 signal amplitude too small (intermittent)	Oil ingress in connector or cracked tracks	Clean/replace connector, reseal cable gland; replace encoder if amplitude < 1 Vpp
F248 Battery voltage too low stored in drive log	Buffer battery on controller < 2.6 V	Replace lithium cell; reset date/time; clear alarm history

Model	Frame Ø	Winding code	Stand-still torque MN (Nm)	Rated speed (rpm)	Holding brake	Typical use case highlight
MKE118D-027-BG0-KE4	118 mm	27	140	3 000	None	Balanced mix of torque & speed for ATEX zone 1 packaging lines
MKE118D-035-NG0-KE4	118 mm	35	187	3 000	None	Higher-torque version – heavier indexing tables in hazardous areas
MKE118D-027-BG0-KE6	118 mm	27	140	3 000	None	Same winding as reference but with KE6 corrosion-resistant connectors
MKE118B-024-NG0-KE4	118 mm	24	115	4 500	None	High-speed winding for direct-coupled centrifuges in zone 2
MKE118D-058-NG1-KE4	118 mm	58	250	2 500	None	Peak-torque variant for heavy agitators; NG1 cable routing

Ordering Codes

Error code	What it means
F219	Motor over-temperature shutdown — winding sensor indicates ≥ 155 °C
F8022	Encoder 1: signals incorrect (missing, noisy or out-of-range feedback)
F230	Max. signal frequency of encoder 1 exceeded — commanded speed too high or gearing error
F236	Excessive position-feedback difference between encoder channels
F8025	Over-voltage in power section — DC-bus above safe limit during braking
F8060	Over-current in power section — short-circuit or peak current beyond rating
F8057	Device overload shutdown — sustained load or heatsink temperature too high
F8069	±15 V internal analogue supply out of tolerance (device hardware fault)
F8070	+24 V control-voltage error — external supply below 21 V or above 30 V
F248	Battery voltage too low (< 2.8 V) — replace absolute-encoder backup battery within two weeks
