Encoder
communication error
(EcCe)
1. Encoder communication feedback error
2. CRC checksum error
Action and Reset
Action condition
Verify if the encoder feedback data CRC is correct in each sampling cycle
Action time
Pr.10-46 high bit determines the allowed continuous number of times
For example: Pr.10-
46 = 050D, the allowed continuous number of times is 5
errors
Fault treatment parameter
N/A
Reset method
Manual reset
Reset condition
N/A
Record
Yes
Cause
Corrective Actions
Encoder is interfered by the noise,
causing encoder feedback packet
error
1. Check the PG card wiring and anti-interference performance
2. If the drive continuously receives faults more than 5 times (single-turn
counting error, encoder lost, encoder communication error, PG command
error, etc.), the keypad displays the code of the last error. You can reset the
error after the fault.
