5. OPERATIONAL FUNCTIONS
5.6 Home position reset function (data set function)
The home position reset function (data set function) is a function that resets the current position to the home
position. Prior to executing the home position reset function, set the home position coordinates (parameter
No.0246, 0247). The movement is the same as the data set method return to home position, where the current
position is changed to the home position coordinates (parameter No.0246, 0247). This function can be used
independent of the method for returning to home position. If absolute position detection system is used,
whether or not data for absolute position detection system (home position multiple revolution data (parameter
No.024D), home position within 1 revolution position (parameter No.024E, 024F)) are changed can be selected
using return to home position option 2 (parameter No.0241).
The home position reset function is valid after home position return complete. If the home position reset
function is used prior to home position return finish (home position return request (ZREQ) is ON), a home
position return not complete error (operation alarm 90, detail 01) occurs.
Start operation is performed according to the following procedure.
(1) Move to an arbitrary position using JOG operation or something similar.
(2) Set home position coordinates for resetting.
(3) Turn on the home position reset mode (DST).
(4) Turn on the start fast operation signal (FST).
API LIBRARY
Use the sscDataSetStart function to perform procedures (3) to (4) above.
Use the sscGetDriveFinStatus or sscWaitIntDriveFin functions to check
completion of operation.
