[Cd.321] Synchronous encoder axis control method
Set the control method for the synchronous encoder axis.
0: Current value change .......... The synchronous encoder axis current value and the
1: Counter disable ................... Input from the synchronous encoder is invalid. Smoothing
2: Counter enable .................... Input from the synchronous encoder is valid.
[Cd.322] Synchronous encoder axis current value setting address
Set a new current value in synchronous encoder axis position units to apply to the current
value change for the synchronous encoder axis (Refer to section 2.2.1).
[Cd.323] Synchronous encoder axis error reset
If set to "1", "[Md.326] Synchronous encoder axis error No." and "[Md.327] Synchronous
encoder axis warning No." are set to 0 and then "b4: Error detection flag" and "b5: Warning
detection flag" of "[Md.325] Synchronous encoder axis status" are turned OFF. A
synchronous encoder connection becomes valid if there is no error.
The Simple Motion module resets the value to "0" automatically after completion of the
error reset.
However, the setting of the synchronous encoder axis will not be valid even if the error is
reset for the setting error of the synchronous encoder axis parameter. Reconfigure the
parameter and turn the power supply ON again.
synchronous encoder axis current value per cycle are
changed as follows. Set the new current value in "[Cd.322]
Synchronous encoder axis current value setting address".

[Md.321]
Synchronous encoder axis
current value per cycle
processing, phase compensation processing and rotation
direction restriction processing are continued. While these
processes are valid, the input axis speed may not stop
immediately when the counter disable is selected.

A value that is converted "[Cd.322]
Synchronous encoder axis current value

"[Pr.324] Synchronous encoder axis length
per cycle-1".
