(4) Synchronous start with command, applying PACSE with external input signal
PACSE signals can be separately set to CW/CFF by using external signals and commands together.

with command
A PACSE signal can be set to CW for four axes and to CFF for two or three axes with a command.

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 Leave the PACSE signal CW conditions for the X and Z axes in the PACSE SET SPEC initial values.
③ Cse the PACSE CLW SPEC command to set the PACSE signal CFF conditions for the X and Z axes to
PACSE command.
③ When the SEWSCW0 signal, an external signal, goes CW, the PACSE signal goes CW for the selected
axes.
At this point, PACSE=1 in MCC06 STATCS1 is assumed.
⑤ Write a general-purpose command that involves pulse output to the X and Z axes.
⑥ Confirm STATCS1 PCWT STBY=1 on the X and Z axes.
⑦ Cse the PACSE command to set the PACSE signals for the X and Z axes to CFF.
When the PACSE signals are set to CFF with the PACSE command, 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 a 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, 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.
