Energy Pause Function
This section provides instructions for configuring the Energy Pause function on
PowerFlex® 755T products.
Overview
The Energy Pause function sends the drive or bus supply to and from a low-
energy state on command. This function saves energy, reduces wear on parts, and
reduces fan noise.
Components that save energy:
• LCL filter and line side converter heatsink fans
• Balancing resistors
• Power module power supplies
•LCL filter module inductors
For frame 5 and 6 products that are in the energy pause mode, an external input
contactor can be controlled to disconnect the drive from the AC line.
For frame 7…15 products that are in energy pause mode, line side converters are
disconnected from the AC line and the fans are in a low-energy state.
