s and Settings
Assign the process data for the Digital Input Units to the axis functions as shown below in the detailed
settings on the Axis Basic Settings Display.
You can review the Pulse Output Unit process data that was automatically assigned in the detailed set-
tings on the Axis Basic Settings Display.
Additional Information
You can use external inputs 0 and 1 on the Pulse Output Unit as external latch inputs 1 and 2
by setting the External Input Function Selection parameters. If you perform homing with the MC
Function Module, external latch 1 (external input 0) is used as the home input. If you do not use
external latch 2 (external input 1) for latching, select a general input for the External Input Func-
tion Selection parameter. If you select a general input, you can use the external input as a limit
input or other input.
Application Example
If you use the MC Function Module and use and the latching function of the Pulse Output
Unit only for homing, set the external input 0 of the Pulse Output Unit as the external latch
input 1 and use it as the home input. You can set external input 1 as a general input and
use it as the home proximity input or another input. In this case, you can change the set-
tings of the digital inputs of the MC Function Module to assign the input bits.
Refer to External Input Function Selection on page 8-65 for the External Input Function Selec-
tion parameters of the Pulse Output Unit. For the digital input settings of the MC Function Mod-
ule,
