AFE VDC Demand parameter sets the required DC link voltage for the common DC link bus. Recommended level for nominal drive voltage rating of
400V (with 820V overvoltage trip level and 410V undervoltage trip level) is 720V.
AFE VDC Min Level parameter defines the level of DC link voltage at which external precharge closure is instigated. By default it is equal to
undervoltage trip level.
For any additional adjustments (if required) the full set of the AFE related parameters can be found in the Parameters::Regen Control::AFE menu.
Other (non-AFE) drives, supplied through common DC bus MUST have the following set-up:
DC Link volts limit feature disabled
If in V/Hz mode the Terminal Voltage Mode parameter set to FIXED
AFE Application
A standard AFE macro (App_5_AFE_Control) is included as part of the default application. It provides necessary application layer logic to operate in
AFE control mode. This macro can be modified (if necessary) using standard AC30 PDQ or PDD tools. It enables the user immediate operation
without any additional diagram logic wiring, providing that electrical connections to digital inputs and outputs are the same as in default AFE macro.
