This chapter describes the communication profiles used in the
communication between the Ethernet POWERLINK network, the
REPL-01 module, and the drive.
Communication profiles are ways of conveying control commands
(Control Word, Status Word, references and actual values)
between the master station and the drive.
With the REPL-01 module, either the CANopen DSP 402 (Device
Profile Drives and Motion Control) profile or the ABB Drives profile
may be employed. The Control Word, Status Word, references
and actual values of these profiles are described in the following
sections.
This section describes the basic functionality of the DSP 402
profile. The DSP 402 is a standardized device profile used for
digital controlled motion products (e.g. frequency converters) and
is part of the CANopen specification. Additional information can b
e obtained from CAN-CIA website.
The start and stop of the drive and several mode specific
commands are executed by the Device Control state machine.
This is described in figure
