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.
