142 EtherNet/IP – Start-up
7. Define the process data transferred to and from the drive in
parameter groups 52 and 53.
Note: The adapter module assigns the Control word, Status
word, references 1…2 and actual values 1…2 automatically to
cyclical communication according to the selected assembly
instances.
8. Validate the settings made in parameter groups 51, 52 and 53
with parameter 51.27 FBA par refresh.
9. Set the relevant drive control parameters to control the drive
according to the application.
Examples of appropriate values are shown in the tables below.
Parameter setting examples – ACS850 and ACQ810
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 value
of parameter 51.23 is 128, an ODVA speed reference value of
±30000 (decimal) corresponds to an equal amount of rpm in the
drive. The speed reference value sent from the PLC is limited by
parameter 20.01 Maximum speed in the forward direction and
20.02 Minimum speed in the reverse direction.
