See Chapter 6 about explanation of Polled I/O message. Set rotational speed:1800min-1 (0708hex). Acceleration / Deceleration command are dependant on the inverter setting. Both rotational speed and run command set from DeviceNet. (3) Change rotational speed command: 600min-1 (0258hex). Set rotational speed:1800min- 1 (0708hex).

There are two ways to communicate with the master, one is polled I/O message communication and the other one is explicit message communication. Also SJ-DN corresponds to the AC Drive profile. 6. 2 Basic DeviceNet specification The table below describes basic DeviceNet specification of this product.
