Communication Starting and Operation
Checking with CJ1W-NCx82 Master
After completing the settings and wiring, turn ON the power and check that the communication starts.
The inverter power supply must be turned ON to set the inverter. When the power supply is turned ON,
the inverter may operate in unintended way. Check the condition of the wiring and system carefully
before starting the operation.
Check the condition of the wiring and system carefully, and then turn ON the power supply for all the
inverters and PLC. It does not matter whether the inverter or PLC power supply is turned ON first.
However, an error occurs unless the power supply for all the inverters is turned ON within a certain time
(All Registered Slave Participation Standby Time parameter of CJ1W-NCx82, default value is 10
seconds) after turning ON the PLC power supply.
Firstly,enter the network settings. Until the settings are performed, the indicators show "Initial
processing status" in the table below for both the Master Unit and the EtherCAT Communication Unit.
Start CX-Programmer, and double-click the target CJ1W-NCx82 in the I/O table to start the support
tool. When the support tool starts, the Network Auto Setup dialog box is displayed. Perform the network
setup in accordance with the dialog box instructions. If the Network Auto Setup dialog box is not
displayed automatically, start the dialog box by selecting Network Auto Setup from Network in the
support tool menu.
For details on network setting, refer to Position Control Units
CJ1W-NC281/NC481/NC881/NCF81/NC482/NC882 OPERATION MANUAL (Cat No.W487).
Check that the Master Unit has transitioned to normal operation from initial processing.
The indicators of the CJ1W-NCx82 make it easy to check the changes in status.
