09-05= 0：8 bits data
09-06= 1：7 bits data
RS-485 communication error detection time(09-06)
Stop selection of RS-485 communication failure(09-07)
09-07= 0：Deceleration to stop by deceleration time (00-15)
09-07= 1：Coast to stop
09-07= 2：Deceleration to stop using the deceleration time of 00-26 (emergency stop time)
09-07= 3：Keep running(warning message only, press the stop button to stop operation)
Communication fault tolerance count(09-08)
When the number of communication errors exceeds the value set in parameter 09-08 the inverter
will display the communication fault alarm.
09-09：Wait time of inverter transmission
Sets the inverter response delay time. This is the time between the controller message and the start
of the inverter response message. Refer to figure 4.3.76. Set the controller receive time-out to a
greater value than the wait time parameter (09-09).
