Chapter 6 Absolute Reset and Absolute Battery
6.1 Absolute Reset
The Battery-less absolute type or absolute type, controllers retain the encoder position data
even with power is OFF. For those types, it is unnecessary to perform home-return operation
every time the power is turned on.
For absolute type, register the home position (absolute reset) in case of (1) to (3).
(1) Initial activation
(2) When the power to the controller is turned off and absolute battery is replaced
(3) The encoder cable is taken off the controller
For Battery-less absolute type, register the home position in case of (1) to (2).
(1) Replacement of motor
(2) When absolute error generated (in such case as initial activation)
The absolute reset is performed by using a teaching tool such as PC software.
Described below are the steps how to perform it.
[1] Absolute Reset Procedures
1) Connect the controller with the actuator. [Refer to Chapters 1 and 2.]
2) Connect the absolute battery (Enclosed battery if starting up for the first time, new battery if
replacing) to the absolute battery connecting connector on the front panel of the controller.
[Refer to 6.2 Absolute Battery.]
3) Put the operation mode setting switch on the front panel of controller to MANU side, and turn
ON the power to the controller.
4) The absolute encoder error appears on the teaching tool. Perform alarm reset.
5) Perform home-return operation. Once the home return is complete, the point of origin is
memorized at the same time the origin point is established.
6) Repeat the steps 1) to 5) to all the connected absolute type actuators.
[Reference] By marking the home position for each actuator on the mechanical side, it will be
easy to adjust the position in case the home position is misaligned in the next
absolute reset.
[Refer to Repeatability of Home Position described below for the details.]
In below explains the procedure using each teaching tool:
(1) For PC software
Select position data on the main screen and click the Alarm button.
Turn the servo ON with Servo button, and press Home button.
