CHAPTER 5
OPERATION
5.2 Operate with Rotational speed command•k min
Following information indicate the example of the inverter control data at P046: 21, P047: 71 and P049: 4.
See Chapter 6 about explanation of Polled I/O message.
Explanation on each data frame.
[Output frame]
(1) Stop command. Set rotational speed:1800min
dependant on the inverter setting. Both rotational speed and run command set from DeviceNet.
(2) Forward running command.
(3) Change rotational speed command: 600min
(4) Stop command.
(5) Reverse running command. Set rotational speed:1800min
(6) Stop command.
[Input frame]
(7) Stop condition
(8) While the inverter is forward run condition and accelerating, "XX" represents rotational speed.
(9) Constant speed condition. Revolutions arrive at 1800min
(10) Deceleration condition.
(11) Constant speed run condition. Revolutions arrive at 600min
(12) Deceleration condition.
(13) Stop condition.
(14) The inverter is in the reverse run condition and accelerating.
(15) Constant speed condition. Revolutions arrive at 1800min
(16) Deceleration condition.
(17) Stop condition.
