run, a fault is generated. This fault can be disabled in parameter 238 - [Fault
Config] bit 7 (PWM SyncLost).
When operating as a Stand Alone unit (DPI MASTER) and PWM Carrier
Synchronization is enabled, the Converter needs to know if it should
synchronize to a 700VC or a 700S. This selection is done in parameter 51 -
[Option Select] Bit 6 (700VC Invtr). This bit must be set for a 700VC and
cleared for a 700S. PWM carrier synchronization can only be done with one
inverter, so any other inverters on the common bus will have higher
common mode voltage.
Converter Faults When set to operate as a Coupled unit (DPI SLAVE), any fault in the
Converter is passed to the Inverter so all the faults are recorded in the
Inverter fault queue. When set to operate as a Stand Alone unit (DPI
MASTER), the Converter maintains its own fault queue.
Converter Faults as a Coupled Unit (DPI SLAVE)
When using PowerFlex 700 Vector Control, the fault from the Converter is
added to a base number of 300, so all the Converter faults are numbered 301
to 399. The pop-up window on the HIM alerts the user to look at the fault
log in the PF700AC to get the specific fault text.
When using PowerFlex 700S Phase II Control, the faults from the Converter
are all combined into one fault code (F110) in the Inverter. The pop-up
window on the HIM alerts the user to look at the fault log in the PF700AC
to get the specific fault text.
