Note) To use inter-drive communication (),  can't be set at  for master inverter. ■Communication parameters (standard RS485)

These parameters are used to set or change the data transmission speed, the parity, inverter numbers and the communication error trip timer with the control panel and or a linked control.

※：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.
