Soft starters rated up to 75 Hp (at 460V ) for standard applica-tions in three-phase networks are available. Extremely small sizes, low power losses and simple start-up are just three of the many advantages of this soft starter. 1) Actual motor start times are load dependent. Application The 3RW30 soft starters are suitable for soft starting of

S801+ soft starter unless a means to turn off the soft starter when disconnect switch is open is used. Opening disconnect while the soft starter is operating may cause a malfunction. Closing disconnect switch while the soft starter is operating will result in a soft starter failure and potential equipment damage and personnel hazard. CAUTION

The sizing must be based on the load curve, number of starts per hour and load type. 2) H1 = Control voltage 110 V / H2 = Control voltage 220 V. 3) 1,100 and 1,400 A models have control voltage of220 V.

A soft starter uses voltage to control the current and torque. The motor torque is approximately proportional to the square of the applied voltage. % Torque α% 

cycle that the soft starter will be running (passing current). AC53b: Bypassed soft starters The rating depends on the number of starts per hour, the length and current level of the start, and

speed throughout the acceleration and deceleration ramps by varying its output frequency, a soft starter only controls average voltage to the motor and cannot accurately control motor speed. Therefore, motor speed during acceleration and deceleration can vary with load. Example: a conveyor soft starter could have a Start Time of 10s.

functionality with soft starters. When a soft starter is starting (or soft stopping) a motor, the voltage supplied to the motor is being altered by switching of the SCRs. The result of varying the conduction angle switching point of the SCRs is a non-sinusoidal voltage waveform being supplied to the motor. Soft starters often use back-

this setting could potentially save energy costs. The soft starter has the CE mark and should not need extra filtering for harmonics. Other soft starters may not have the CE mark and may need filtering. Drive Drives are typically 95 98 % efficient. During start, run, and stop (unless set to coast stop), active components such as IGBTs are on.
