FR-A700: USB automatic recognition
Normally, operation panel (PU connector) is the command
source. During USB connection, USB is the command
source.
FR-D700, F700PJ : Parameter unit automatic recognition
FR-E700(SC): USB automatic recognition
During USB connection, USB is the command source.
Normally, operation panel is the command source. When the
parameter unit is connected to the PU connector, PU is the
command source.
Note
• Always reset the inverter after making the setting of the parameters. After you have changed the communication
related parameters, communication is not established until the inverter reset.
