Fieldbus control with
embedded fieldbus
What this chapter contains
The chapter describes how the drive can be controlled by external devices over a
communication network using embedded fieldbus.
System overview
The drive can be connected to an external control system through a fieldbus adapter
or embedded fieldbus. For the fieldbus adapter control, see chapter
The embedded fieldbus supports Modbus RTU protocol. Modbus is a serial,
asynchronous protocol. Transaction is half-duplex.
The embedded fieldbus can be connected with either EIA-485 (terminal X1 of the
optional FMBA-01 Modbus adapter connected to drive terminal X3) or RS-232
(control panel connector X2).
EIA-485 is designed for a multipoint application (a single master controlling one or
more slaves). RS-232 is designed for a point-to-point application (a single master
controlling one slave).
For more information on the FMBA-01 Modbus adapter module, see
