Reset command (RESET)
This command returns the program step to the first step of the lead program, and
turns DO0 - DO12*

, SO200 - SO231, and the memory I/O all off. The point variable
“P” is also cleared to 0. (Does not clear the counter variables “C” and “D”.
* The output from a parallel I/O port used for emulated serialization does not change
even if reset with the RESET command.
* When the “origin return completed action selection” parameter (single-axis con-
trollers: PRM33, dual-axis controllers: PRM2) is 1 or 3, DO4*
2
does not turn OFF
even if reset with the RESET command. In the same way, if the “servo status output
selection” parameter (single-axis controllers: PRM46, dual-axis controllers: PRM21)
is 1, DO7*
3
does not turn OFF even if reset with the RESET command.

The lead program is a program selected by switching to the last program run by HPB
or POPCOM.
The lead program can also be switched by running the “@SWI” communication com-
mand. It can also be switched even when program data is loaded from the memory
card.
*1: DO0 to DO4 when the SRCP/SRCD series controllers are used.
*2: DO5 when the DRCX series controllers are used.
*3: DO3 when the SRCP/SRCD series controllers are used.
