Active Converter
Communication The active converter communicates control and starts information with the
700S controller over DPI Data Link D.
• 700AC Parameter 71 - [Converter Status] is transferred to 700S
Parameter 657 - [DPI Data In D1]. This may be used to monitor the
operation of the active converter.
• 700S Parameter 666 - [DPI Data Out D1] is transferred to 700AC
Parameter 70 - [Converter Control]. This may be used to start and stop
the converter.
• 700S Parameter 667 - [DPI Data Out D2] is transferred to 700AC
Parameter 72 - [Converter Min Vdc]. This may be used to set the
minimum DC link voltage reference.
For more information, please refer to the PowerFlex 700 Active Converter
Power Module User Manual (Publication No. PFLEX-UM002…).
Auto Tune Operation The pre-charge bypass contactor must be closed and the converter must be
enabled before Auto Tuning of the inverter can be performed. See the
section below on Pre-charge Operation to accomplish this.
700S Parameter 431 sets the current level for the Auto Tune procedure. The
default value of 50.0% is high for large horsepower drives. A typical value
for a motor connected to an LPM20 drive is 20.0%.
After the converter is ready and parameters are set correctly, the Auto Tune
operation can be initiated from the HIM as described in the PowerFlex 700S
High Performance AC Drive — Phase II Control User Manual (Publication
No. 20D-UM006…).
