Normal Stopcommand and the RUN input changing from true to false will command a NormalStop.ValuesRead-WriteData Type“Coast” (0) – Power removed from motor, motor coasts to zero.“Ramp” (1) – Decelerates to zero speed at the decel rate.“Ramp to Hold” (2) – Decelerates to zero speed at the decel rate, followed by DCbraking until the next start sequence.“DC Brake” (3) – DC braking is immediately applied (does not follow programmeddecel ramp).“DCBrkAutoOff” (4) – Applies DC braking until zero speed is reached or DC braketime is reached, whichever is shorter.“Current Lmt” (5) – Max torque / current applied until zero speed“Fast Brake” (6) – High slip braking for maximum braking performance abovebase speed.Bus Reg Mode ABus Reg Mode BBus Regulation Mode A, BMethod and sequence of the DC bus regulator voltage. Choices are dynamicbrake, frequency adjust or both. Sequence is determined by programming ordigital input to the terminal block.Dynamic Brake SetupIf a dynamic brake resistor is connected to the drive, both of these parametersmust be set to either option 2, 3 or 4.DefaultOptions:1 = “Ramp”0 = “Coast”0 = “Coast”1 = “Ramp”2 = “Ramp to Hold”3 = “DC Brake”4 = “DCBrkAutoOff”5 = “Current Lmt”6 = “Fast Brake”RW 32-bitIntegerDRIVE CFGBraking Features372373Default:Options:1 = “Adjust Freq”4 = “Both-Frq 1st”0 = “Disabled”1 = “Adjust Freq”2 = “Dyn Brake”3 = “Both-DB 1st”4 = “Both-Frq 1st”RW 32-bitInteger!ATTENTION: The drive does not offer protection for externally-mounted brake resistors. A risk of fireexists if external braking resistors are not protected. External resistor packages must be self-protected fromover-temperature or the protective circuit shown in Figure C.1 on page C-2 (or equivalent) must be supplied.374 Bus Reg Lvl CfgBus Regulation Level ConfigurationSelects the reference used to determine the bus voltage regulation level for thebus voltage regulator and the reference used for the dynamic brake.“Bus Memory” (0) – References are determined based on P12 [DC Bus Memory].“BusReg Level” (1) – References are determined based on the voltage set in thebus regulator level parameter P375 [Bus Reg Level]. If coordinated operation ofthe dynamic brakes of a common bus system is desired, use this selection andset the P375 [Bus Reg Level] to coordinate the brake operation of the commonbus drives.Default:Options:0 = “Bus Memory”0 = “Bus Memory”1 = “BusReg Level”RW 32-bitIntegerPowerFlex 750-Series User Manual – Publication 750-UM001C-EN-P – September 2009
