3.3.2 PIO Pattern Selection and PIO Signal
[1] PIO Pattern (Control Pattern) Selection
PIO Converter can extend the positioner function of ERC3, and enables to have 6 types of
control methods. Set the suitable PIO pattern to Parameter No.25 “PIO Pattern Select”.
Check the 4.2.3 Operation in Positioner Mode 2 for the details of PIO Patterns.

Note 1 The position zone signal output can be switched over to the zone signal output with the
setting of Parameter No.149.
*1 Zone signal output : Zone range is to be set to either Parameter No.1, 2 and it is
always available after the home-return operation is complete.
*2 Position zone signal output : This feature is associated with the specified position number.
The zone range is set in the position table. The zone range is
enabled only when the position is specified but disabled if
another position is specified.
