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 XSEL 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 XSEL 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 XSEL 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 XSEL PC software (X_SEL.exe) on the PC. The following explains the operation steps in the XSEL
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.)
