Setpoint to the desired level Current Limit Only Current Step uses the Current Limit feature exclusively This method of starting eliminates the Soft Start voltage current ramp and instead maximizes the effective application of motor torque within the limits of the motor In this mode Setpoint RAMP TIME 1 is set to minimum so that the output current jumps to the current limit setting immediately Typically used with a limited power supply when starting a difficult load such as a centrifuge or a deep well pump when the motor capacity is barely adequate stall condition or overloading occurs or if other starting modes fail Since ramp times are set to minimum START RAMP 1 TYPE is set to either VOLTAGE or CURRENT Initial Torque Initial Voltage 1 or Initial Current 1 Sets the initial start point of either Voltage Ramp or the Current Ramp Every load requires some amount of torque to start from a standstill It is inefficient to begin ramping the motor from zero every time since between zero and the WK2 break away torque level no work is being performed The initial torque level should be set to provide enough torque to start rotating the motor shaft enabling a Soft Start and preventing torque shock damage Setting this start point too high will not damage the starter but may reduce or eliminate the soft start effect Ramp Time 1 Sets the maximum allowable time for ramping the initial voltage current torque or power setting t
