Chapter 6 Absolute Reset and Absolute Battery
6.1 Absolute Reset
The controller of absolute specification holds encoder position information by 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) Replacement of absolute battery
(3) Disconnection of encoder cable from controller
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 MSCON 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
1) Select position data on the main screen and click the Alarm button.
2) Select the position data in the main window and press Servo ĺ Home.
