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 via a fieldbus adapter or
embedded fieldbus. For fieldbus adapter control, see chapter
The embedded fieldbus supports Modbus RTU protocol. Modbus is a serial,
asynchronous protocol. Transaction is half-duplex.
Embedded fieldbus connection is either RS-232 (control panel connector X2) or
RS-485 (terminal X1 of the optional FMBA Modbus Adapter connected to drive
terminal X3). The maximum length of the communication cable with RS-232 is
restricted to 3 meters. For more information on the FMBA Modbus Adapter module,
see
FMBA-01 Modbus Adapter Module User’s Manual
[3AFE68586704 (English)].
RS-232 is designed for a point-to-point application (a single master controlling one
slave). RS-485 is designed for a multipoint application (a single master controlling
one or more slaves).
