8 Pulse Output Units
8 - 40 NX-series Position Interface Units User’s Manual (W524)
The following is a configuration example for a system that controls a stepper motor drive.
*1. Assign these signals to the MC Function Module axis in the basic axis motion control settings.
*2. Error inputs cannot be controlled from the MC Function Module. Handle error inputs as input signal device
variables and control operations to save inputs, output sequencing, and other operations from the user pro-
gram. You cannot use instructions such as the MC_Power and MC_Reset instructions for control.
*3. These signals are used for instructions that use the latch function. External input 0 (latch input 1) is also used
for the home input during homing. Refer to 8-10-6 External Input Function Selection on page 8-65 for informa-
tion on using the home input signal. If you use the MC Function Module but do not use the home input signal,
set the homing method of the Home (MC_Home) instruction to 11 (Limit inputs only) or 14 (Zero position pre-
set).
The following is a configuration example for a system that controls a Servo Drive.
*1. Assign these signals to the MC Function Module axis in the basic axis motion control settings.
