Chapter 5 Energy Pause Function

System Requirements

The Energy Pause function is available in PowerFlex 755TL low harmonic drives,

755TR regenerative drives, and 755TM bus supplies.

• Firmware revision 3 or later is installed.

• A customer-supplied 24V DC power source is connected to the control

bus at terminal TB5.

Monitor Status with Energy

Pause

Three machine states govern the energy pause function: Owned, Paused, and

Resuming. These states are a subset of the states that are required to support the

CIP Energy Power Management object. The names come from that object.

Monitor the status of the state machine with parameter 0:59 [Energy Status].

Energy Status

Displays the state of the energy function.

Bit 1 ‘Owned’ – indicates that the product (drive or bus supply) is in the ‘Owned’ state. AC precharge is complete and the product is operational. The product moves to the

‘Paused’ state if it receives an Energy Pause command.

Bit 2 ‘Paused’ – indicates that the product is in the ‘Paused’ state. In this state, the product disconnects from three-phase AC power to save energy. The product moves to the

‘Resuming’ state if it receives an Energy Resume command (removal of Energy Pause).

Bit 4 ‘Resuming’ – indicates that the product is in the ‘Resuming’ state. This state means that the product is transitioning from the ‘Paused’ to the ‘Owned’ state. In this

state, the product connects to three-phase AC power and performs the AC precharge function. The product moves to the ‘Owned’ state when it successfully completes the

AC precharge function.

Bit 16 ‘Cls Ext Cont’ – the energy function sets this bit to close an external contactor to connect the line side converter to three-phase power. Connect a digital output

function that energizes to close an external contactor. For example, in the I/O card set parameter 10 [RO0 Sel] to this parameter and address. Connect the relay output to the

contactor to energize the coil that closes the contactor. The energy function clears this bit in the Paused state. The bit is set in the ‘Resuming’ and ‘Owned’ states.
