SP600 AC Drive User Manual
Sets the reaction to a loss of input power. Power loss is recognized
when:
• DC bus voltage is
≤
73% of DC Bus Memory and Power Loss
Mode is set to Coast.
• DC bus voltage is
≤
82% of DC Bus Memory and Power Loss
Mode is set to Decel.
0 = Coast: The drive coasts to stop if the bus voltage drops below
the threshold level. (Output transistors disabled.)
1 = Decel: Provides inertia ride-through, which may prevent the
drive from the need to reconnect to the motor. By recapturing the
mechanical energy, converting it to electrical energy, and returning it
to the drive, the bus voltage is maintained. As long as there is
mechanical energy, the ride-through time is extended, and the
motor remains fully fluxed up. If AC input power is restored, the
drive can ramp the motor to the correct speed without the need for
reconnecting.
Sets the time that the drive will remain in power loss mode before a
fault is issued.
