Precautions for Correct Use
A Pulse Output Unit outputs pulses in one control period equivalent to the deviation between
the implemented command position and the command current position. For the Velocity-contin-
uous Pulse Output Method, pulses are output according to the implemented command velocity.
Therefore, observe the following precautions if you check the pulse output without using the
MC Function Module.
• When you change the Pulse Output Unit to Operation Enabled status, pulses may be sud-
denly output if there is a difference between the command position and the command current
position. That may cause the equipment or machine to operate unexpectedly. Make sure that
there is no difference between the command position and the command current position
before you change the status.
• When you output pulses, change the command position in small increments to avoid rapid
movement.
If you use the MC Function Module, the MC Function Module controls these aspects. There-
fore, when you check wiring with a Pulse Output Unit, we recommend that you use the MC
Function Module.
Additional Information
If you check the wiring for a Pulse Output Unit without using the MC Function Module, perform
the following operations.
Refer to 8-8 I/O Data Specifications on page 8-31 for details on I/O data.
External Inputs
Monitor the corresponding bit for the external input status that is assigned as I/O data.
External Outputs
Manipulate the corresponding bit for the external output that is assigned as I/O data and
check to see if the output turns ON and OFF.
Pulse Outputs
The operation to output pulses depends on the Output Mode Selection parameter.
As given below, change the status of the Pulse Output Unit with the Controlword and then
manipulate the command values and check the pulse output.
• Manipulate the Controlword that is assigned as I/O data, implement the Shutdown, and
then implement the SwitchON + Enable Operation commands. Then, place the Pulse Out-
put Unit in Operation Enabled status.
You can check the status of the Pulse Output Unit with the Statusword that is assigned as
I/O data.
• Perform the following operation according to the Output Mode Selection to check the pulse
output.
Position-synchronous Pulse Output
Change the command position that is assigned as I/O data and check the pulse output.
Velocity-continuous Pulse Output
Change the command position and command velocity that are assigned as I/O data and
check the pulse output.
