Cause : Drive position feedback interface power supply overload comes when the Encoder 1 trip indicates that the drive encoder power supply has been overloaded. Terminals 13 &14 of the 15 way D type connector can supply a maximum current of 200 mA @ 15 V or 300 mA @ 8 V and 5 V.

1. Check encoder power supply wiring.
2. Disable the termination resistors (Pr 03.039 set to 0) to reduce current consumption.
3. For 5 V encoders with long cables, select 8 V (Pr 03.036) and install a 5 V voltage regulator close to the encoder.
4. Check the encoder specification to confirm if it is compatible with the encoder port power supply current capability.
5. Replace the encoder.
6. Use an external power supply with higher current capability.
