(b) Pulse input reception at an external signal input occurs as follows
1) Reception of pulse inputs from the external synchronous encoder begins
when the clutch is switched ON.

2) The clutch control mode
(Note-3)
operation will be identical its operation at
the external input mode. The synchronous encoder and clutch operations
occur in a corresponding manner.
(2) Operation END
(a) Operation at the synchronous encoder axis is ended when the REAL mode
is established in response to a VIRTUAL to REAL mode switching request
(M2043 switched from ON to OFF).
(b) The procedure for ending operation at the synchronous encoder axis is as
follows.
1) Stop the output module
Stop the external synchronous encoder.
Switch the connected clutch OFF.
2) Switch from the VIRTUAL to REAL mode.
CAUTION
Switching to the REAL mode while synchronous encoder axis and output module operation is in
progress will cause a sudden stop at the output module, resulting in a servo error, and the
machine will be subjected to a jolt.
