(2) WARNING The drive generates an ENCODER 1/2 CABLE warning. This is the
recommended setting if the maximum pulse frequency of sine/cosine
incremental signals exceeds 100 kHz; at high frequencies, the signals
may attenuate enough to invoke the function. The maximum pulse
frequency can be calculated as follows:
90.10 ENC PAR REFRESH FW block: ENCODER (see above)
Setting this parameter to 1 forces a reconfiguration of the FEN-xx interfaces, which is needed for any
parameter changes in groups 90…93 to take effect.
The parameter is read-only when the drive is running.
(0) DONE Refreshing done.
(1) CONFIGURE Reconfigure. The value will automatically revert to DONE.
