Soft starting
Operating principle
A voltage ramp is used to implement soft starting. The 3RW51 soft starter increases the motor
voltage from a parameterizable starting voltage to the line voltage within a definable ramp-up
time.
Application
• Systems in which a startup of the drive without interfering jerky movements is required.
• E.g. pumps or small fans
