P3.4.11 FREQUENCY TO START DC BRAKING AT RAMP STOP (ID 515)Use this parameter to set the output frequency at which the DC braking starts.P3.4.12 FLUX BRAKING (ID 520)Use this parameter to enable the Flux Braking function.You can use flux braking as an alternative to DC braking. Flux braking increases the brakingcapacity in conditions where additional brake resistors are not necessary.When braking is necessary, the system decreases the frequency and increases the flux in themotor. This increases the capacity of the motor to brake. The motor speed is controlledduring braking.You can enable and disable Flux Braking.CAUTION!Use the braking only intermittently. Flux braking converts energy into heat and cancause damage to the motor.P3.4.13 FLUX BRAKING CURRENT (ID 519)Use this parameter to set the current level for the flux braking.10.5 I/O CONFIGURATION10.5.1 PROGRAMMING OF DIGITAL AND ANALOGUE INPUTSThe programming of inputs of the AC drive is flexible. You can freely use the available inputsof the standard and optional I/O for different functions.Use the formats below to give the value for the programmable parameters:• DigIN SlotA.1 / AnIN SlotA.1 (graphical keypad) or• dI A.1 / aI A.1 (text keypad).Selection name Example DescriptionInput type DigIN / dIDigIN / dI = Digital inputAnIN / aI = Analogue inputSlot type Slot A The board type:A / B = Vacon AC drive standard boardC / D / E = Option board0 = The parameter signal is not connected to any terminalTerminal number 1 The number of the terminal on the selected board.PARAMETER DESCRIPTIONS VACON · 13124-HOUR SUPPORT +358 (0)201 212 575 · EMAIL: VACON@VACON.COM 10
