80ADVANCED PARAMETER-SETTING MODECommissioning manual Powerdrive MD2/FX4617 en - 2017.09 / e5.7.2 - Explanation of parameters in menu 606.01 : Stop modeAdjustment range : Coast (0), Ramp (1),Ramp + DC (2), Zero speed DC (3),Timed DC (4)Factory setting : Ramp (1)Format: 8 bitsCoast (0):The drive stops in freewheel mode.The power bridge is deactivated as soon as the stop commandis given.The drive cannot receive another run command during thetime programmed in 06.63, the motor demagnetisation time.After this stopping time, the drive is «ready». The machinestopping time depends on its inertia.Ramp (1):Stop on deceleration ramp.The drive decelerates the motor according to the decelerationmode chosen in parameter 02.04.One second after the stop, the drive is «ready».Ramp + DC (2) ( ):Stop on deceleration ramp with DC injection for an imposedperiod of time.The drive decelerates the motor according to the decelerationmode chosen in parameter 02.04.When zero frequency is reached, the drive injects DC with amagnitude which can be set in parameter 06.06 for a timedefined by parameter 06.07.The drive is «ready».Zero speed DC (3) ( ):Stop by braking using low frequency current injection, then DCinjection at zero speed.The drive decelerates the motor by imposing a low frequencycurrent until it reaches almost zero speed, which the drivedetects automatically.The drive then injects DC with a magnitude which can be set inparameter 06.06 for a time defined by parameter 06.07. Norun command can be taken into account until the drive is«ready».MotorspeedtTimeFreewheel stop timeStopMotorspeedtTimeDecelerationrate 1 secStopMotorspeedMotorcurrenttTimeDecelerationrateStopDCinjection06.07Motor current06.06Motor speedMotor currenttTimeBraked stopMotorcurrentLow frequencycurrent injectionDCinjection06.0606.07Stop
