134 EtherNet/IP – Start-up
Parameter setting examples – ACS355
Speed control using the ODVA AC/DC drive profile,
Extended speed control assembly
This example shows how to configure a speed control application
that uses the ODVA AC/DC drive profile, Extended speed control
assembly. In addition, some application-specific data is added to
the communication.
The start/stop commands and reference scaling are according to
the ODVA AC/DC drive profile. For more information, see section
ODVA AC/DC drive profile on page 161.
When Reference 1 (REF1) is used for speed control and the
parameter 5123 value is 128, an ODVA speed reference value of
±30000 (decimal) corresponds to an equal amount of rpm in the
drive. The reference value sent from the PLC is limited by
parameter 1105 REF1 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.
