PowerFlex 700L Active Converter Power Module User Manual
In addition to Type 3 communication, the 700S may optionally use DPI data
links to control the sequencing of the Converter from a Logix processor as
shown below. This requires the Converter to be configured for Manual
Control in Converter parameter 50 - [Start Config]. The reference for the
voltage loop may also be controlled by a Logix processor when Converter
parameter 160 - [Voltage Loop Sel] is set to Manual Ref.
The DPI data links between the Inverter and Converter are enabled by
setting Converter parameters 300 - [Data In A1] through 317 - [Data Out
D2] to the parameter number of the data to send or receive. When a DPI
data link is used by the Converter, that channel cannot be used by a different
communication card. The following example illustrates using DPI data links
between the Inverter and Converter.
Suppose Inverter parameter 666 is linked to Converter parameter 52 -
[Manual Control], Inverter parameter 667 is linked to Converter parameter
60 - [DcLink Reference], and Converter parameter 71 - [Converter Status] is
linked to Inverter parameter 657. This requires Converter data links to be
configured as follows:
•
Active Converter parameter 306 [Data In D1] = 52
•
Active Converter parameter 307 [Data In D2] = 60
•
Active Converter parameter 316 [Data Out D1] = 71
This example shows Data Link D being used to communicate with the
Converter. The Converter supports DPI Data Links A, B, C, and D so any
group could be used as needed.
All the options for starting and stopping the Converter are explained in
greater detail in
