5. OPERATIONAL FUNCTIONS
POINT
• When using the following home position return methods, set proximity dog
signal and limit switch signal so that the Z-phase can be passed during home
position return.
• Dog method
• Dog cradle method
• Limit switch combined method
• When performing Z-phase detection method home position return, the Z-
phase is required to be passed through with the JOG operation etc.
When the Z-phase is not passed, not passing Z-phase (operation alarm 91,
detail 01) occurs. However, when "1: Not need to pass motor Z phase after
the power supply is switched on" is selected in the home position setting
condition selection of parameter No.1190 (servo parameter PC17 function
selection C-4), the home position return can be executed even when the Z-
phase is not passed, and the restriction above is removed.
• Set 1 (valid) in No home position of the control option 1 (parameter No.0200)
when setting the position at the time of power on as the home position. Once
a home position return is performed, a position determined by the home
position return is set to the home position.
• In the home position return, smoothing filter is invalid.
• In the Z-phase detection method, shortcut direction can be selected for home
position return direction (parameter No.0240). When shortcut direction is
selected in other home position return methods than Z-phase detection
method, home position return parameter setting error (operation alarm 9D,
detail 03) occurs when the operation starts.
