General-purpose
Sequence Input 0
(Servo ON Input)
You can allocate the input signal to use with
a parameter.
Controls turning the Servomotor ON and
OFF (supplying/not supplying power).

General-purpose
Sequence Input 3
(Mode Switch
Input)
You can allocate the input signal to use with
a parameter.
Switches between mode 0 and mode 1.
ON: Program Table Operation Mode is
entered (mode 0).
OFF: Jog Speed Table Operation or Homing
Mode is entered (mode 1).

/SI1*
(/START-
STOP,
/HOME)
42
General-purpose
Sequence Input 1
(Program Table
Operation Start-
Stop Input or
Homing Input)
You can allocate the input signal to use with
a parameter.
Mode 0: When the signal turns ON, program
table operation starts or restarts. Refer to
/SEL0 to /SEL4 when starting.
When this signal turns OFF, the program
table operation is stopped.
Mode 1: When the signal turns ON, homing
is started or restarted.
When the signal turns OFF, homing is can-
celed.

/SI2*
(/JOGP,
SEL0)
43
General-purpose
Sequence Input 2
(Forward Jog
Input or Program-
Specified Area 1
Input)
You can allocate the input signal to use with
a parameter.
Mode 0: Program table selection 0
Mode 1: Forward jog operation starts when
the input signal turns ON. (Jog operation
stops when the signal turns OFF.)
/SI5*
(/JOG0,
/SEL2)
45
General-purpose
Sequence Input 5
(Jog Speed Table
Selection Input or
Program-Speci-
fied Area 3 Input)
You can allocate the input signal to use with
a parameter.
Mode 0: Program table selection 2
Mode 1: Jog operation is started when the
input signal turns ON.

/SI6*
(/PGM-
RES,
/ALM-RST)
46
General-purpose
Sequence Input 6
(Program Table
Operation Reset
Input or Alarm
Clear Input)
You can allocate the input signal to use with
a parameter.
Mode 0: If this signal turns ON while a pro-
gram table operation is stopped, the pro-
gram table operation will be reset.
Mode 0 or mode 1: An alarm is reset.
(There are a limited number of general-pur-
pose input signals, so this signal is used for
two functions. Both /ALM-RST and /PGM-
RES are used to reset errors.)
/SI4*
(/JOGN,
SEL1)
44
General-purpose
Sequence Input 4
(Reverse Jog
Input or Program-
Specified Area 2
Input)
You can allocate the input signal to use with
a parameter.
Mode 0: Program table selection 1
Mode 1: Reverse jog operation is per-
formed. (Jog operation stops when the
signal turns OFF.)
