Cause : Encoder 1 has been activated by parameter but the encoder interface (FEN-xx) cannot be found.
Check parameter 90.01 ENCODER 1 SEL setting corresponds to encoder interface 1 (FEN-xx) installed in drive Slot 1/2 (signal 9.20 OPTION SLOT 1 / 9.21 OPTION SLOT 2).
Note: The new setting will only take effect after parameter 90.10 ENC PAR REFRESH is used or after the JCU control unit is powered up the next time.
