8-9-3 Setting Examples
This section describes the minimum parameter settings that are required to use a Pulse Output Unit
with the MC Function Module.
Refer to 8-10-1 Parameters on page 8-52 for information on Pulse Output Unit parameters.
Set the Pulse Output Method parameter, to either Forward/reverse direction pulse or Pulse + direction
according to the pulse input specifications of the connected motor drive.
The default setting for the Pulse Output Unit parameter is Forward/reverse direction pulse.
Refer to 8-10-2 Pulse Output Method on page 8-53 for information on the pulse output method.
In the Output Mode Selection parameter setting, select one of the following output modes according to
the connected motor drive and control application.
• Position-synchronous pulse output (for servomotor control)
• Velocity-continuous pulse output (for stepping motor control)
The default setting for the Pulse Output Unit is for a position-synchronous pulse output.
Refer to 8-10-3 Output Mode Selection on page 8-55 for information on the pulse output methods.
Set the External Input Function Selection and External Input Logic Selection parameters.
The Pulse Output Unit has two inputs.
Leave the input functions at their default settings to use the Unit with the MC Function Module.
The default settings set the inputs to Latch Input 1 and Latch Input 2 and set both to N.O. (Normally
open).
Refer to 8-10-6 External Input Function Selection on page 8-65 for information on external input sig-
nals.
Set the External Output 0 Function Selection and External Output 0 Logic Selection parameters.
The Pulse Output Unit has one output.
You can select between General output and Error counter reset output for the output function.
Select Error counter reset output to use the Pulse Output Unit with the MC Function Module.
When you use the MC Function Module and select Error counter reset output as the output function,
ON/OFF control for this output signal is performed automatically when the home position is detected
(latch 1 input).
This automatically resets the following error counter for homing when a Servo Drive is connected.
If you do not want to reset the Servo Drive’s following error counter or if a stepper motor drive is con-
nected, set the output function to General output.
The default setting is for General output set to N.O. (Normally open).
Refer to 8-10-4 External Output on page 8-59 for information on external output signals.
