10 Application Cases
8-6) Homing
The homing mode involves the servo drive and the host controller. Set the homing mode according to the
following table.

Select the homing mode of the host controller and set the homing speed, acceleration, and home offset
based on actual mechanical conditions.

Introduction to homing
Function block: MC_Home and MC_HomeWithParameter
1) Set MC_Home in the preceding figure and MC_HomeWithParameter in the function block.
2) The two function blocks both include 10 kinds of homing modes.
MC_Home
MC_HomeWithParameter
Designates the homing action to be modified.
0: Promixity reverse turn/home proximity input OFF
1: Proximity reverse turn/home proximity input ON
4: Home proximity input OFF
5: Home proximity input ON
8: Limit input OFF
9: Proximity reverse turn/home input mask distance
11: Limit inputs only
12: Proximity reverse turn/holding time
13: No home proximity input/holding home input
14: Zero position preset
■
Home proximity input OFF: The host controller searches for the home signal after reaching the falling
edge of the home proximity switch.
■
Home proximity input ON: The host controller searches for the home signal after reaching the rising
edge of the home proximity switch.
■
Proximity reverse turn: If the home proximity signal is ON when homing is enabled, the host
controller reverses the running direction immediately after reaching the falling edge of the home
proximity signal.
