Inverter Parameter Setup - Hitachi SJ200 Series Instruction Manual

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.
Func.
Name
Code
A001 Frequency source setting
A002 Run command source setting
C071 Communication speed selection
C072 Node allocation
C074 Communication parity selection
C075 Communication stop bit selection
C076 Communication error select
C077 Communication error time-out
C078 Communication wait time
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.
