UPS Option The PowerFlex 7000 “C” Frame drive has the option for internal and external
UPS power to keep the control power active within the drive in the event of a
control power loss. The following diagram shows the current configuration of the
internal UPS option:
Figure 273 - 300W AC/DC Power Supply
The UPS is installed in the incoming cabling section, below the LV control
section.
The UPS will keep control power to all the critical 120VAC loads and an extra
AC/DC Power Supply that feeds the DC/DC Power Supply for powering all the
drive control components. The main drive cooling fan, and the AC/DC Power
Supply that feeds the IGDPS boards are not powered from this UPS.
The UPS is configured for the AS400 communication protocol, and has several
status signals that are fed back to the Customer Interface Board to allow the
control to respond to various conditions including low batteries, loss of input
power, UPS on bypass, etc.
If the customer has an external UPS, the firmware will essentially not expect any
of the signals mentioned in the above section, and will not display any
information relating to the UPS status. The firmware will operate in the same
manner with respect to the operation of the drive with an internal or external
UPS.
