Setting of operation mode of the inverter
• The inverter has three operation modes.
External operation mode: For giving a start command and a frequency command with an external potentiometer or
switches which are connected to the control circuit terminal.
PU operation mode: For giving a start command and a frequency command from the operation panel, parameter unit, or
RS-485 communication via the PU connector.
Network operation mode (NET operation mode): For giving a start command and a frequency command via the RS-485
terminals, a communication option, or the Ethernet connector.
*1 For the details of Pr.79 , refer to the Instruction Manual of the inverter.
*2 Operation mode cannot be directly changed between the PU operation mode and Network operation mode.
• Controllability through communication
Refer to the following table to select the appropriate operation mode for the connection. Switching of the operation mode
is available using "test operation" (on
page 164 ) or "parameter list" (on page 99 ) on the sub window. Refer to the Instruction
Manual (Detailed) of the inverter for details of each parameter.
Monitoring and parameter read can be performed from any operation regardless of the operation mode.
