Ramp-Up Detection - Siemens SIRIUS 3RW30 Manual

Ramp-up detection

The SIRIUS soft starter has a motor ramp-up detection function that is always active
regardless of the start mode. If it detects a motor startup, the motor voltage is immediately
increased to 100 % of the mains voltage. The thyristors of the soft starter are bridged by the
bypass contacts integrated in the device and the successful startup is indicated by means of
the BYPASS output and the STATE / BYPASSED LED.
