Enc15
Drive encoder trip: The number of periods per revolution calculated from encoder data
during auto-configuration is either less than 2 or greater than 50,000.
165
Linear motor pole pitch / encoder ppr set up is incorrect or out of parameter range
i.e. Pr 5.36 = 0 or Pr 21.31 = 0.
Faulty encoder.
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
176 Replace feedback device
Et External trip from input on terminal 31
6
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
