    Introduction 1.1.2 Operating Mode of the SIRIUS 3RW44 Electronic Soft Starter The 3RW44 soft starter has two antiparallel thyristors in each of the phases. There is one thyristor for the positive and one thyristor for the negative half wave. Using phase angle control and various control methods, the r.m.s. value of the motor voltage is increased from a definable start voltage or start torque to the motor rated voltage within a selectable starting time.

    Stopping Modes Different stopping functions can be selected thanks of the large numbers of applications for which the SIRIUS 3RW44 soft starter can be used. The motor stop can be set optimally according to application and deployment. If a start command is output while the motor is being stopped, this process is aborted and the motor is started up again using the specified starting mode.
