5.2 Operate with Rotational speed command [min
-1
]
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
-1
(0708hex). Acceleration / Deceleration command are
dependant on the inverter setting. Both rotational speed and run command set from DeviceNet.
(2) Forward running command.
(3) Change rotational speed command: 600min
-1
(0258hex).
(4) Stop command.
(5) Reverse running command. Set rotational speed:1800min
-1
(0708hex).
(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
-1
.
(10) Deceleration condition.
(11) Constant speed run condition. Revolutions arrive at 600min
-1
.
(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
-1
.
(16) Deceleration condition.
(17) Stop condition.
