Cause : Encoder 2 has been activated by parameter but the encoder interface (FEN-xx) cannot be found.
Check parameter 90.02 Encoder 2 sel setting corresponds to actual encoder interface 1 (FEN-xx) installed in drive Slot 1/2 (parameter 09.20 Option slot1 / 09.21 Option slot2).
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
