Output Function List
Output function
specification
value
Function name Remarks
0 General-purpose output
1 Operation-cancellation level or
higher error output (ON)
* The following output functions cannot be assigned at the same time:
• Operation-cancellation level or higher alarm output (ON) (Output function
specification value = 1)
• Operation-cancellation level or higher alarm output (OFF) (Output function
specification value = 2)
• Operation-cancellation level or higher alarm + emergency stop output (ON) (Output
function specification value = 3)
• Operation-cancellation level or higher alarm + emergency stop output (OFF) (Output
function specification value = 4)
2 Operation-cancellation level or
higher error output (OFF)
(Same as “Output function specification value = 1”)
3 Operation-cancellation level or
higher error + emergency stop
output (ON)
(Same as “Output function specification value = 1”)
4 Operation-cancellation level or
higher error + emergency stop
output (OFF)
(Same as “Output function specification value = 1”)
5 READY output (PIO trigger
program operation enabled)
* The following output functions cannot be assigned at the same time:
• READY output (PIO trigger program operation enabled) (Output function
specification value = 5)
• READY output (PIO trigger program operation enabled AND absence of operation-
cancellation level or higher error) (Output function specification value = 6)
• READY output (PIO trigger program operation enabled AND absence of cold-start
level or higher error) (Output function specification value = 7)
6 READY output (PIO trigger
program operation enabled AND
absence of operation-
cancellation level or higher
error)
(Same as “Output function specification value = 5”)
7 READY output (PIO trigger
program operation enabled AND
absence of cold-start level or
higher error)
(Same as “Output function specification value = 5”)
8 Emergency stop output (ON) * The following output functions cannot be assigned at the same time:
• Emergency stop output (ON) (Output function specification value = 8)
• Emergency stop output (OFF) (Output function specification value = 9)
9 Emergency stop output (OFF) (Same as “Output function specification value = 8”)
10 AUTO mode output
11 Auto operation status output (Other parameter No. 12)
12 All-valid-axes home (= 0) output * To move the absolute-encoder axis to coordinate 0 or the preset home coordinate, use
a MOVP command instead of a HOME command.
13 All-valid-axes home return
complete (coordinate confirmed)
output
* To move the absolute-encoder axis to coordinate 0 or the preset home coordinate, use
a MOVP command instead of a HOME command.
14 All-valid-axes preset home
coordinate output
* To move the absolute-encoder axis to coordinate 0 or the preset home coordinate, use
a MOVP command instead of a HOME command.
15 Voltage-low warning output for
system-memory backup battery
16 Voltage-low warning output for
absolute-data backup battery
All axes are checked by the OR gate. Once an abnormal level has been detected, the
signal will remain ON until a power ON reset or software reset is performed.
17 Drive-source cutoff (SDN)
notification output
The output port will turn OFF when the drive source is cut off.
(* Caution: This notification output is implemented only by software means.)
18 For future expansion
19 For future expansion
20 ~ 23 For future expansion
24 Axis 1 servo-ON status output
25 Axis 2 servo-ON status output
26 ~ 29 For future expansion
The following assignments are prohibited:
• Assign a specification value not included in the I/O function lists.
• Assign the same input function specification value, which is not for general-purpose input, to multiple input ports.
• Assign the same output function specification value, which is not for general-purpose output, to multiple output ports.
(For the conditions associated with each specification value, refer to the Remarks field of the applicable item.)
If a prohibited assignment is set, an error “I/O function assignment error” will generate and all input ports and output ports will become
general-purpose inputs and general -purpose outputs, respectively.
* In the positioner mode, input and output function assignments are ignored. Each function will follow the corresponding specification in the
positioner mode.
