Modbus Jazz With VFD Rockwell Powerflex 4M


Recommended Posts



Assuming you have the JZ20-R16, you will need install the JZ-RS4  Module to the JAZZ to be able to work with MODBUS.

     ( You will be programming the JZ20 via the USB Port, and can go online with the JAZZ  to troubleshoot your program)

There is an Example program in   HELP-Examples-MODBUS  that will show the steps to setup MODBUS in the JAZZ-M90  Controllers

     ( You have to use the Special Functions  Methods -  See Help - MODBUS for further details)

From the Description provides, the JAZZ will be the MODBUS Master  .

Look up the JZ-RS4 Installation manual  to review it's settings and wiring.
