PLC
The PowerFlex 6000 uses a Micro850 PLC to perform many of its internal
control functions. The PLC controls and monitors the cooling fans, input and
bypass switching devices, door switch status, etc. The PLC is also responsible for
interfacing with the user's automation control system via many optional
communication protocols. Standard communication protocols are EtherNet/IP,
Modbus/TCP Server and Modbus RTU. Optional communication modules are
available to support other communication protocols.

HMI
The PowerFlex 6000 HMI is a PanelView Plus 700 series, catalog number 2711P-
T7C4D9.
The HMI is connected to the Master Control board through a communication
interface (standard RJ45 EtherNet/IP connection). The HMI configures
operating parameters and input operation commands, and displays the operation
status, operation parameters, and fault messages.
UPS
The UPS supplies power to the LV Control cabinet using internal batteries if the
customer-supplied control power and isolation transformer control power is off.
The UPS provides control power in the event of transient power loss to ensure
the drive control can operate without interruption.
