SM1868
Axis 2 start
instruction
OFF: Not executed
ON: Being executed
• This relay turns on when positioning
control by the start instruction
(IPPSTRT2(P), IPDSTRT2(P),
IPSIMUL(P), IPABRST2), JOG operation
by the JOG start instruction (IPJOG2), or
OPR control by the OPR start instruction
(IPOPR2(P)) is started.
• This relay turns off when positioning
control, OPR control, or JOG operation is
completed.

Axis 2 error
reset
OFF  ON:Resets the
Axis 2 error.
OFF: Clears the reset
status.
• Turning on this relay will turn off SM1865
and SM1866 and will clear the SD1865
and SD1866 values to "0".
• Even if this relay is turned on, SM1865
will not turn off and the SD1865 value will
not be cleared to "0" until SM1860 turns
off.
