Parameter setting examples – ACS355
Speed and torque control using the ABB Drives -
Enhanced communication profile
This example shows how to configure a speed and torque control
application that uses the ABB Drives - Enhanced profile. In
addition, some application-specific data is added to the
communication.
The start/stop commands and reference are according to the ABB
Drives profile. For more information, see the state machine on
page 65 .
When Reference 1 (REF1) is used, a reference value of ±20000
(decimal) corresponds to the reference set with parameter 1105
REF1 MAX in the forward and reverse directions.
When Reference 2 (REF2) is used, a reference value of ±10000
(decimal) corresponds to the reference set with parameter 1108
REF2 MAX 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.
The table below gives the recommended drive parameter settings.
