If b2-01< E1-09, DC Injectionbraking starts at E1-09.0.0 to10.0 0.5Hz A A A Ab2-02DC Injection BrakingCurrentDCInj CurrentSets the DC injection braking current as a percentage of the Driverated current. 0 to 100 50% A A A -b2-03DC Injection Braking Time atStartDCInj Time @StartSets the time of DC injection braking at start in units of 0.01seconds.0.00 to10.00 0.00sec A A A Ab2-04DC Injection Braking Time atStopDCInj Time @StopSets the time length of DC injection braking at stop in units of 0.01seconds.1.When b1-03 = 2, actual DC Injection time is calculated asfollows: b2-04 * 10 * Output Frequency / E1-04.2.When b1-03 = 0, this parameter determines the amount of timeDC Injection is applied to the motor at the end of the decel ramp.3.This should be set to a minimum of 0.50 seconds when usingHSB. This will activate DC injection during the final portion ofHSB and help ensure that the motor stops completely.0.00 to10.00 0.00sec A A A Ab2-08Magnetic FluxCompensation CapacityField CompSets the magnetic flux compensation as a percentage of the no-loadcurrent value (E2-03). 0 to 1000 0% - - A -Denotes that parameter can be changed when the Drive is running.* For parameter b1-04 settings 0 and 1.Table A.1 F7 Parameter List (Continued)ParameterNo.Parameter NameDigital Operator Display Description SettingRangeFactorySettingControl MethodV/F V/Fw/PGOpenLoopVectorFluxVector
