SJ200 Inverter

6.Inverter Parameter Setup - The inverter has several settings related to ModBus communications. The table below lists them together. The Required column indicates which parameters must be set properly to allow communications. You may need to refer to the host computer documentation in order to match some of its settings.

NOTE: When you edit and store any of the parameters above, the inverter causes it to take effect immediately. ModBus transmission occurs only after you set the OPE/485 DIP switch to the “485” position and turn on the inverter. Note that parameters C071 to C078 cannot be changed via the network. To edit them, reconnect the inverter keypad (or other digital operator) and edit the parameters.
