Chapter 2 Bus Supply Hardware and Parameter Conversion
Bus Supply Hardware
Configuration
The PowerFlex 700AFE bus supply was typically used as ‘stand-alone’ bus
supply. In most cases, the PowerFlex 700AFE operates independent of an
automation controller or PLC using the operator control devices on the
enclosure door.
That said, most drive systems incorporate a communication link between the
bus supply and the controller. In most cases, the controller is programmed to
read and update monitor data, status, alarm, and fault parameters of the bus
supply. However, there are many applications that use network communication
to control certain aspects of the bus supply operation. See Chapter 3
for more
information.
PowerFlex 700AFE Bus Supply Control Devices
The PowerFlex 700AFE IP20/IP21 enclosed DC bus supplies came from the
factory with certain door mounted operator control devices (selector switches,
pushbuttons, pilot lamps, and so on) prewired to the included digital I/O.
These operator devices are configured by default to control the bus supply
without connection to an automation controller or PLC. IGBT modulation
can also be controlled via the communication Logic Command Word Bit-0
“Stop” and Bit-1 “Start”.
Figure 18
and Figure 19 show typical power and control circuit wiring of a
frame 10 MCC enclosure. The significant difference between the IP20 2500
MCC and IP21 Rittal versions is that the IP21 Rittal design uses a motor-
operated circuit breaker, MCCB instead of an AC contactor. Similar wiring
diagrams for the PowerFlex 700AFE in IP21 Rittal enclosure can be found in
publication 20Y-UM001
