Condition Selection Of Home Position Set - Mitsubishi Electric MELSEC iQ-R16MTCPU Programming Manual

Condition selection of home position set

A home position return must be made after the servomotor has been rotated more than one revolution to pass the axis
through the Z-phase (motor reference position signal) and the "[St.1066] Zero pass (R: M32406+32n/Q: M2406+20n)" has
been turned ON. 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), Condition selection of home position set" of servo parameter (expansion setting parameter), if it does
not pass zero point with the motor rotation after turning the servo amplifier power ON, the "[St.1066] Zero pass (R:
M32406+32n/Q: M2406+20n)" can be turned ON.
Setting data
Set the following "servo parameter" using MT Developer2 to select the "function selection C-4 (PC17)".
Set the servo parameters for every axis.

Precautions
• When "1: Not need to pass motor Z phase after the power supply is switched on" is set as the above servo parameter, a
restrictions such as "make the home position return after the servomotor is rotated more than one revolution to pass the
axis through the Z-phase (motor reference position signal)" is lost.
• 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), 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.
• When the above parameter is changed, control circuit power supply of the servo amplifier is turned OFF to ON after
resetting or turning power OFF to ON of Multiple CPU system.
• Set "0: Need to pass motor Z phase after the power supply is switched on" in the "function selection C-4
(PC17)" of servo parameter (expansion setting parameter) for the home position return by the scale home
position signal detection method. If "1: Not need to pass motor Z phase after the power supply is switched
on" is set, a minor error (error code: 1978H) will occur at the home position return start and the home
position return is not executed.
• When executing home position return by dogless home position signal reference method, set the servo
parameter (expansion parameter) "Function selection C-4 (PC17)" by the servo amplifier connected.
