INTERLOCK
DI
0-15V/24V
COMD The interlock is released at Low level.
*1
It varies depending on the number of power supplies. *
（
Refer to Table 4-5 in item 4-6)
*2
Input Low level for 200msec or more.
*3
Even if the arc processing time setting is 100us or less, the output will be 100us. Even if arc processing is
performed multiple times during 100us, only one 100us output is generated. This time can be changed from the
menu.
*4
Since there is no corresponding output control mode, a warning will be processed.
