5 POSITIONING CONTROL
5.21 Home Position Return
Set home position return retry function to "valid".
When set as "invalid" at the detection of the external limit switch, an error occurs and stops.
■ Operation B
"Operation B" of a home position return by the dogless home position signal reference method is shown below.
• If an external limit switch is detected during home position return operation, an error occurs and stops.
• Home position return retry function cannot be used.
■
Operation C
"Operation C" of a home position return by the dogless home position signal reference method is shown below.
• When the position where address of absolute linear encoder becomes 0 is in the home position return direction
• If an external limit switch is detected during home position return operation, an error occurs and stops.
• Home position return retry function cannot be used.
