• SEW-Eurodrive Fault F01 (Overcurrent): Causes, Sub-Codes, and How to Isolate Drive vs Motor vs Cable

  28 Jul, 2026

  SEW-Eurodrive F01 is an overcurrent trip on MOVIDRIVE B and MOVITRAC B. Decode MOVIDRIVE B sub-error codes 0-14, apply the P138 ramp-limit fix, and use one lockout-and-meter session to prove whether the drive, the motor, or the cable is at fault.

• SEW-Eurodrive Fault F14 (Encoder Error): Sub-Codes 0 and 25-34, Hiperface, Resolver, and X14/X15 Wiring Checks

  28 Jul, 2026

  Decode MOVIDRIVE B fault F14 by sub-code: 25 = X15 encoder past 6542 rpm, 28/29 = RS485 errors on X15/X14, 31-33 = Hiperface, 34 = resolver. Plus the cable, shield, and encoder-type checks that actually clear it.

• SEW-Eurodrive Fault F31 (TF/TH Sensor Tripped): Motor Thermistor Troubleshooting on MOVITRAC B and MOVIDRIVE B

  28 Jul, 2026

  SEW fault F31 means the motor's TF thermistor or TH thermostat tripped — or the sensor loop is open. How to ohm out the loop, when to jumper X10:1-X10:2 on MOVIDRIVE B, and what P835 controls.
