Page 444 [Pr.43] Home position return method
*2 The home position return operation follows the home position return direction set in the driver (servo amplifier) and does not refer to
"[Pr.44] Home position return direction". However, "[Pr.44] Home position return direction" must be set when using the backlash
compensation function.
When the positioning is executed in the reverse direction against "[Pr.44] Home position return direction", the backlash compensation is
executed in the axis operation such as positioning after the driver home position return. Set the same direction to "[Pr.44] Home position
return direction" of the Motion module and the last home position return direction of the driver (servo amplifier).
Checking the home position return parameters
[Pr.43] to [Pr.55] are checked with the following timing.
• When the "PLC READY signal [Y0]" output from the CPU module to the Motion module changes from OFF to ON
