4-5 Checking Wiring
Use the functionality of the Sysmac Studio to check the wiring. The procedure depends on whether the
MC Function Module is used.
When the MC Function Module is used to control motion, use the MC Test Run and axis status monitor
(MC monitor table) functions of the Sysmac Studio.
You can use these functions to monitor sensor signals and to check the wiring to external devices, such
as motor drives and encoders, without any programming.
For details on the MC Test Run and axis status monitor (MC monitor table) functions, refer to the
NJ/NX-series CPU Unit Motion Control User’s Manual (Cat. No. W507) and to the Sysmac Studio Ver-
sion 1 Operation Manual (Cat. No. W504).
Precautions for Correct Use
If you assign an Incremental Encoder Input Unit to an encoder axis, you cannot monitor the
external inputs with the Axis Status Monitor (MC Monitor Table).
To check the external inputs of the Incremental Encoder Input Unit, use the procedures in
Pro-
cedures When Not Using the MC Function Module on page 4-33, below, before you assign the
Unit to an encoder axis.
If you do not use the MC Function Module, use the I/O Map and Watch Tab Page to check the wiring.
• For inputs, you can turn ON and OFF the input from the external device that is connected to the Unit
you need to check and monitor the results. If the input device is an encoder, you can rotate the
encoder to change the input value and monitor the results.
• For outputs, you can use forced refreshing to control the output to the Unit you need to check to con-
firm the operation of the connected external device.
If you use the I/O Map, you can conveniently monitor status or perform forced refreshing without defin-
ing variables or creating an algorithm to check the wiring.
Refer to the Sysmac Studio Version 1 Operation Manual (Cat. No. W504) for the procedures to monitor
status or perform forced refreshing.
Also, you can use the I/O checking function to check wiring by connecting the Sysmac Studio to the
peripheral USB port on the EtherCAT Coupler Unit. This allows you to check wiring in the following
cases.
• If you need to check the wiring when the CPU Unit is temporarily unavailable, such as when commis-
sioning the system
• If you need to check the wiring when EtherCAT network wiring is not completed, such as when com-
missioning the system
• If you need to check wiring when the CPU Unit and EtherCAT Slave Terminal are not connected
• If it is necessary for more than one person to check the wiring when more than one EtherCAT Slave
Terminal is used
Refer to the NX-series EtherCAT Coupler Unit User’s Manual (Cat. No. W519-E1-03 or later) for infor-
mation on I/O checking.
