6 -22Coast to Stop with TimerIf the Stop Command is input (i.e., the Run Command is turned OFF) when b1-03 is set to 3, the Inverter out-put is interrupted to coast the motor to a stop. After the Stop Command is input, Run Commands are ignoreduntil the time T has elapsed. The time T depends upon the output frequency when the Stop Command is inputand the deceleration time.Fig 6.19 Coast to Stop with Timer Using the DC Injection BrakeSet constant b2-03 to apply the DC injection braking current to the motor while it is coasting to a stop, to stopthe motor and then restart it.Set b2-03 to 0 to disable the DC injection brake at start.Set the DC injection brake current using b2-02.Related ConstantsCon-stantNumberName Description SettingRangeFactorySettingChangeduringOpera-tionControl Methods MEMOBUSRegis-terV/fV/fwithPGOpenLoopVec-torFluxVec-torb2-02DC injectionbraking cur-rentSets the DC injection brakingcurrent as a percentage of theInverter rated current.The DC injection braking cur-rent in flux control is affected byany change to the setting of E2-03.0 to100 50% No A A A No 18AHb2-03DC injectionbraking timeat startUsed to set the time to performDC injection braking at start inunits of 1 second.Used to stop coasting motor andrestart it.
