GV6000 AC Drive User Manual

• “Continue” – Allow the drive to power the motor down to half bus voltage.

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.

13.34.4 Coast

This is the default mode of operation.

The drive determines a power loss has occurred if the bus voltage drops below

Vtrigger. If the drive is running the inverter output is disabled and the motor coasts.

The power loss alarm in Drive Alarm 1(211) is set and the power loss timer starts.

The Alarm bit in Drive Status 1 (209) is set if the Power Loss bit in Alarm Config 1(211)

is set.

The drive faults with a F003 – Power Loss Fault if the power loss timer exceeds Power

Loss Time (185) and the Power Loss bit in Fault Config 1 (238) is set.

The drive faults with a F004 – UnderVoltage fault if the bus voltage falls below Vmin

and the UnderVoltage bit in Fault Config 1 (238) is set.

The pre-charge relay opens if the bus voltage drops below Vopen and closes if the bus

voltage rises above Vclose

If the bus voltage rises above Vrecover for 20mS, the drive determines the power loss

is over. The power loss alarm is cleared.
