Chapter 6 Adjustment of Operation
6.1 Absolute Reset and Absolute Battery
6.1.1 Absolute Reset
PIO Converter is necessary for Simple Absolute Type. Simple Absolute Type retains the
encoder position information in the battery backup. It is not necessary to perform the
home-return operation every time the power is turned ON.
In order to hold the encoder position information, absolute reset is required.
Provide absolute reset in the following cases:
(1) Initial activation
(2) When the absolute battery was replaced with the power to the PIO converter is shut, and
(3) When disconnected the power supply and I/O cable for the actuator from PIO Converter
The absolute reset is performed by using a teaching tool such as PC software or PIO. The
absolute reset using PIO is available in Positioner Mode 2. Also, the absolute reset cannot be
performed on Quick Teach.
Caution: If it is Pulse Train Control Mode, it would not comply with simple
absolute type. Take the greatest care.
