UPS Option
The PowerFlex 7000 “B” 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 85 - 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 uses the AS400 communication protocol, and feeds several status
signals back to the ACB to control responses to various conditions including low
batteries, loss of input power, UPS on bypass, etc.
