6.2.3

Parameters Relating to External Interface

z PIO Pattern Selection (No. 25 IOPN)
Parameter No. 25 is used to select a desired PIO operation pattern.
This is a basic operation parameter, so be sure to set it at the beginning.

Setting of
Parameter No. 25

Features of PIO pattern

0

Solenoid valve mode 0
Each movement complete signal is handled in the same manner as an auto switch of an
air cylinder.
A movement complete signal is output as the actuator passes the applicable position,
even when positioning is not performed.
A ready output signal is provided, but no zone output signal is available.

1

Solenoid valve mode 1
A movement complete signal is output upon completion of positioning following a move
command.
A zone output signal is provided, but no ready output signal is available.

The factory setting is “0” [Solenoid valve mode 0].

z Positioning Complete Signal Output Mode (No. 39 FPIO)
This parameter defines the positioning complete signal state to be applied when the servo turns off or “position
deviation” occurs while the actuator is standing still after completion of positioning in solenoid valve mode 1.
The following two scenarios can be considered:
[1] The actuator position has deviated beyond the value set in the “Positioning band” field of the position table,

due to external force applied while the servo was on.

[2] The actuator position has deviated beyond the value set in the “Positioning band” field of the position table,

due to external force applied while the servo was off.

This parameter provides flexibility as to how the “positioning complete signal state” is monitored in accordance
with the characteristics of the applicable system or sequence circuit of the PLC.
The table below shows how the ON/OFF state of a positioning complete signal changes in accordance with each
setting of Parameter No. 39.

Setting of
Parameter No. 39

Definition of rear end complete (PE0), front end complete (PE1),

and intermediate point complete (PE2) signal state

0 [PEND]

[1] When the servo is on
The signal remains ON even when the current position has deviated from the range
corresponding to the value set for the target position in the “Positioning band” field of the
position table.
[2] When the servo is off
The signal turns OFF unconditionally regardless of the current position.

1 [INP]

Regardless of the servo on/off status, the signal turns ON if the current position is inside
the corresponding to the value set for the target position in the “Positioning band” field of
the position table, and turns OFF if it the current position is outside the range.
* The signal effectively functions in the same manner as an auto switch of an air cylinder.

The factory setting is “0” [PEND].
