i have a problem in my commissioning in Modbus interface...

in my project i have omron cp1e plc and one v20 inverter, i have a communication between inverter and plc and my project's goal is to change the speed of inverter, what jobs should i do for only changing the frequency of the inverter

i send stw 047e hex and hsw 2710 hex but inverter doesn't take the value that sent

in summary could u tell me what registers should i change to my goal???

Hello,

Please refer the attached table having information of MODBUS registers. You need to set max. frequency i.e. maximum speed in p2000 i.e. register 40324 & set point frequency in HSW i.e. in register 40003

HTH.
