Modbus RTU Fuji Alpha 5 with Omron NB10

Application​

  • Control Fuji Alpha 5 Servo Motor with Omron NB10 HMI.
  • Servo On and Run would be controlled from PLC with Digital IO.
  • Setting of Speed and Monitoring from HMI
  • PLC outputs are NPN.

Electrical Wiring​

Three types of of Wirings

  • High Voltage wiring for Servo Drive, Servo drive to motor with prefabricated Cables from Fuji.
  • Digital control Wiring between Drive IO Connector and PLC.
  • Low voltage wiring for HMI
  • Communication Cable between Servo Drive and HMI
  • Communication Cable between PC Loader and Drive

Drive and Motor Wiring​

  • Connect 220V AC to L1 and L2 on the Drive.
  • Connect U, V, W on the drive to Motor Power Connector.
  • Encoder cable from Drive CN2 port to Motor Encoder.

Control Wiring​

Fuji Alpha 5 has IO connector on CN1 port.

Parameters​

  • Parameter PA3:01 to 1 for Setting CONT1 Signal as Servo ON.
  • Parameter PA3:02 to 2 for Setting CONT2 Signal as Servo Run in Forward direction.
  • Parameter PA3:02 to 3 for Setting CONT2 Signal as Servo Run in Reverse direction.

To change the direction without modifying CONT2 parameter, Set PA3:02 to 2 and set PA1:04 to 0 for CCW or 1 for CW.

HMI Program​

  • Create a New project in NB-Designer and Select correct HMI Model from PT in Project Library Window.
  • In PLC tab of Project Library Window, Select Modbus RTU Extended.
  • Set Station Number same as Node address of the Fuji Drive
  • From Connectors tab, select Serial Port and connect drive and HMI.
