Enc16 Drive encoder trip: EnDat encoder - The number of comms bits per period for a linear encoder exceeds 255.
166
Select a different type of encoder.
Faulty encoder.
Enc17
Drive encoder trip: The periods per revolution obtained during auto-configuration for a rotary SINCOS encoder is not a
power of two.
167
Select a different type of encoder.
Faulty encoder.
ENP.Er Data error from electronic nameplate stored in selected position feedback device

Check terminal 31 signal
Check value of Pr 10.32
Enter 12001 in Pr xx.00 and check for parameter controlling Pr 10.32
Ensure Pr 10.32 or Pr 10.38 (=6) are not being controlled by serial comms
