The following table lists the functions of the Pulse Output Unit.
Refer to 8-10 Functions on page 8-52 for details on these functions.
1-4-3 Functions of the Pulse Output Unit
Function Description
Pulse output method Allows you to select either forward/reverse direction pulse outputs or pulse +
direction outputs for the pulse output method.
Output mode selection Allows you to select either position-synchronous pulse output or velocity-continu-
ous pulse output for the pulse output mode selection.
External output You can use one external output as a error counter reset output when the Unit is
connected to a Servo Drive and used with the MC Function Module. You can also
control whether the external output is ON or OFF as a general output if you want
to manipulate a device variable directly without the MC Function Module.
Latching You can latch the counter value of the pulse output. You can assign an external
input as a latch input to use two latches at the same time.
External input function selec-
tion
Two external inputs are provided. You can assign them either of the following
input functions: general input or latch input. You can also set the logic for each
input.
Load rejection output setting Allows you to select the pulse stopping method when an error occurs.
You can select from the following two stopping methods: immediate stop or
deceleration stop with set deceleration rate.
Interpolation control for miss-
ing synchronization com-
mand
When a command is missing, the target position is predicted based on previous
commands to continue updating the target position.
Pulse direction change delay When the Pulse Output Unit uses a velocity-continuous pulse output, this setting
sets the wait time when the pulse output direction changes.
I/O refreshing method setting
Sets synchronous I/O refreshing
*1
or task period prioritized refreshing
*1, *2
for the
I/O refreshing

method.
*1. You can select this option only when the Unit is used with a EtherCAT Coupler Unit with EtherCAT communi-
cations in DC Mode.
*2. Unit version 1.2 or later and an NX-ECC203 EtherCAT Coupler Unit are required.
*3. This is the data exchange with the Controller.
