Command interface/source for start command and frequency
command during communication operation
The following table shows a command interface/source in the Network operation mode. A command via
communication is enabled in addition to an external terminal to the CS signal (RS-485 terminals or communication

When Pr.77 = "2", Pr.162 setting can be changed during operation. The new setting is applied after stop. Until the inverter has
stopped, the previous setting of the interface for the operation command and the speed command in the Network operation mode is
Precautions for electronic bypass sequence function
• The response time of the inverter to the signals depends on the command source, NET or External.
After the communication with the inverter is established, the motor operation is performed according to the command via NET.
The commercial power supply operation with the motor is performed when the MRS signal turns ON before the communication
is established. It is recommended to turn the MRS signal ON after the communication is established.
Example: the response time of the inverter to the signals in the Network operation mode (power-ON). The command source is
External for the MRS signal and NET for the STF (STR) and CS signals.
