Speed control using the ABB Drives communication
profile
This example shows how to configure a speed control application
that uses the ABB drives profile.
The start/stop commands and references are according to the ABB
Drives profile. For more information, see the state machine on
page 87.
Reference 1 (REF1) value ±20000 (decimal) corresponds to the
reference set with parameter 19.01 (Speed scaling) in the forward
and reverse directions.
The minimum and maximum 16-bit integer values that can be
given through the fieldbus are -32768 and 32767 respectively.
When configuring the master, you need to map the following
objects to the transmit and receive PDOs. For an example, see
section Mapping objects required for controlling the drive on
page 66.
The table below gives the recommended drive parameter settings.
