Chapter 8 How to Perform An Absolute Encoder Reset (Absolute
Specification)
1. Single Axis, Orthogonal Axis and Rotating Axis
When the absolute-encoder battery voltage of the X-SEL Controller is abnormal or when the battery or
encoder cable is disconnected, an encoder battery error will occur and an absolute encoder reset must be
performed.
This chapter explains how to perform an absolute encoder reset using the PC software. For the absolute-
encoder reset method using the teaching pendant, refer to the operation manual for the teaching pendant.
In the case of a synchro controller, refer to “ Absolute Reset of A Synchro Controller” in Appendix.
1.1 Preparation
(1) PC
A PC in which IAI’s X-SEL PC software (X_SEL.exe) has been installed
(2) Connection cable (the cable supplied with the PC software)
RS232C cross cable (PC-end: female 9-pin, Controller-end: male 25-pin)
(3) All adjustments other than the absolute reset must have been completed.
1.2 Procedure
(1) Turn off the X-SEL Controller power. Turn on the PC power and wait for the operating system to be
started.
(2) Connect the 9-pin, D-sub connector on one end of the connection cable to the communication port on
the PC, and connect the 25-pin, D-sub connector on the other end to the 25-pin communication port
on the controller.
(3) Turn on the controller power. If an encoder battery error is present but no other adjustments are
pending, the 7-segment LED display will show “E914” or “ECA2” indicating that the controller has
detected an encoder battery error.
(4) Start the X-SEL PC software (X_SEL.exe) on the PC. The following explains the operation steps in
the X-SEL PC software.
(5) When the [Connection Confirmation] dialog box is displayed, select the port name you are using on
the PC. Click the [OK] button.
(The software will automatically detect the baud rate.)
