Under certain conditions such as when the ZR unit is connected to the controller for the first time, absolute
encoder battery voltage is abnormal, or encoder cable has been disconnected, an encoder battery error
will generate and absolute reset will be required.
13.3.1 Preparing for Absolute Reset
On the ZR unit, an absolute reset is performed from the ball-screw spline adjustment menu in the PC
software. You also need a special jig to perform an absolute reset.

Connect the robot, controller and PC cable to enable operation from the PC software. Before proceeding, be
sure to confirm that the EMG switch operates properly.
x Carrying out any inspection or maintenance work without fully understanding the work may result in
serious injury.
x Put up a sign that says "Work in Progress" so as to prevent other operators from accidentally operating
the controller, operation panel, etc.
x Back up the parameters before the absolute reset.
