Cautions
• A system which the servomotor can rotate one time or more is required.
• After the proximity dog ON, when a servomotor rotates one time to reverse direction after stop with travel value set in the
"travel value after proximity dog ON", make a system which does not turn OFF the external upper/lower stroke limit.
• Home position return and continuously start of home position return are also possible in the proximity dog ON in the count
method 3. When the home position return and continuously start of home position return are executed in the proximity dog
ON, the home position return is executed after return the axis once to position of the proximity dog OFF.
• When the "travel value after proximity dog ON" is less than the deceleration distance from "home position return speed" to
"creep speed", a minor error (error code: 1A57H) will occur and deceleration stop is made.
• When "1: Not need to pass motor Z phase after the power supply is switched on" is selected in the "function selection C-4
(PC17)" of servo parameter (expansion setting parameter), even if it does not pass zero point at the servo amplifier power
ON, the "[St.1066] Zero pass (R: M32406+32n/Q: M2406+20n)" turns ON. This operation is the same as count method 1.
• If "[St.1062] In-position (R: M32402+32n/Q: M2402+20n)" does not turn ON, home position return is not ended.
