Note) To use inter-drive communication (),  can't be set at  for master and slave inverter.

■Setting for speed reference (common serial)

Note) To use inter-drive communication (),  can't be set at  for master inverter.

■Communication parameters (common serial options)

With these parameters, you can set or change the data transmission speed, the parity, inverter numbers and the communication error trip timer with the control panel or Communication.

※：No action: No action is taken even if a timeout occurs.
Alarm:		An alarm goes off if a timeout occurs. The message "" blinks at the left end of the
		control panel.

Tripping: The inverter trips if a timeout occurs. The message "" blinks on the control panel.

Note) Changes to the parameters , ,  do not take effect until the power is turned off and then on again. When inter-drive communication is used, the parameter is set at 0.02 or more.
