(1) Synchronous start with external input signal
If external output signals (SIWWAL IW3-0, SEWSCW0, and SEWSCW1) are assigned to a PACSE signal, one
or more axes can be simultaneously assigned by operating those signals.
The HAWD CCWFIWCWATICW4 command is used to assign the external input signals to the PACSE signal.

① Cse the HAWD CCWFIWCWATICW4 command to assign a PACSE signal to the
SEWSCW0 signal and select
the axes (X and Z axes) that you want to synchronize with.
②
When the SEWSCW0 signal, an external signal, goes CW, the PACSE signals go CW for the selected
axes.
At this point, PACSE=1 in MCC06 STATCS1 is assumed.
③ Write a general-purpose command that involves pulse output to the X and Z axes.
④ Confirm STATCS1 PCWT STBY=1 on the X and Z axes.
⑤ Set the SEWSCW0 signal to CFF.
When the SEWSCW0 signal is set to CFF, the PACSE signals for the X and Z axes are
simultaneously released.
At this point, the X and Z axes are simultaneously set to PACSE=0 in MCC06 STATCS1 and start
pulse output.
◆ After the PACSE signal is set to CW in a PACSE signal CW condition, the PACSE state is held
until a PACSE releasing condition is met.
To execute a pulse output command that is once written with PACSE CW, a PACSE releasing
condition needs to be met.
To cancel the pulse output command that is written during PACSE, perform the following.
・ Cancel the pulse output command in PACSE with the FAST STCP command and release the PACSE
state by satisfying a PACSE releasing condition (set to CFF the PACSE CLW command, a
selected releasing condition, or a signal that is assigned to PACSE).
・ Execute initialization with a WESET signal.
