Chapter 5 Energy Pause Function
Activate Energy Pause
You can activate the Energy Pause function by setting a bit in the controller, or by
using a discrete-wired digital input. The product must be stopped before an
energy pause request can be sent. If a converter or inverter is modulating, the
drive ignores the request to enter energy pause mode and remains in the Owned
state. The product must detect a rising edge of the energy pause command after
the converter and inverter have been stopped.
Logic Command
For PowerFlex 755TM bus supplies:
• Program the Logix project to set bit 21 ‘Energy Pause’ of the logic
command word to request an Energy Pause command. Link to
Communication of Option Module Logic Command/Status Words. See
the Communication section in the PowerFlex Drives with TotalFORCE
Control Programming Manual, publication 750-PM100
.
• Program the project to clear the bit to request an Energy Resume
command.
For PowerFlex 755TL/TR drives:
• Set parameter 0:63 [LS Start Mode] to 2 ‘ConvLogic’
• Set an output datalink to parameter 0:64 [LS Manual Ctrl]
• Program the Logix project to set parameter 0:64 [LS Manual Ctrl] bit 21
‘Energy Pause]’of word to request an Energy Pause command.
• Program the project to clear the bit to request an Energy Resume
command.
Discrete-wired Digital Input—Frames 5 and 6
The Energy Pause function sets parameter 0:59 [Energy Status] bit 16 ‘Cls Ext
Cont’ to close an external contactor to connect the line side converter to three-
phase power.
Example: Connect a digital output function that energizes to close an external
contactor.
• Set I/O card parameter nn:10 [RO0 Sel] to 000059.16.
This value is the address of parameter 0:59 [Energy Status] bit 16.
• Connect the relay output to the contactor to energize the coil that closes
the contactor.
• The energy function clears this bit 16 in the Paused state.
Bit 16 is set in the Resuming and Owned states.
