330 Control through the embedded fieldbus interface
System overview
The drive can be connected to an external control system through a serial
communication link using either a fieldbus adapter or the embedded fieldbus
interface.
The embedded fieldbus interface supports the Modbus RTU protocol. The drive
control program can receive and send cyclic data from and to the Modbus master on
10 ms time level. The actual communication speed depends on other factors as well,
such as the baud rate (a parameter setting in the drive).
The drive can be set to receive all of its control information through the fieldbus
interface, or the control can be distributed between the fieldbus interface and other
available sources, for example, digital and analogue inputs.
