184 [Power Loss Mode]
Sets the reaction to a loss of input power. Power
loss is recognized when:
• DC bus voltage is ≤ 73% of [DC Bus Memory]

“Coast” = Disable drive and enable the motor to coast.
“Decel” = Decelerate the motor at a rate that regulates the DC Bus until the load’s Kinetic
Energy can no longer power the drive.
“Continue” = Enable the drive to power the motor down to 50% of the nominal DC Bus
voltage.

, for
additional information.
185 [Power Loss Time]

ATTENTION: To guard against drive damage, a minimum line
impedance must be provided to limit inrush current when the
power line recovers. Provide an input impedance equal or
greater than the equivalent of a 5% transformer with a VA rating
6 times the drive’s input VA rating.
