The Contactron speed starter offers the critical functions common in a variable-frequency drive (VFD) without the complexities. It requires no drives expertise or software, making it easy to commission. The starter provides ramp-up and ramp-down functions while the motor is under load. It offers two independently settable operating speeds. The intuitive keypad and rotary knob allow commissioning in minutes. Digital inputs activate user-settable output speeds, so it can be used in place of a traditional across-the-line starter while offering drive-like functionality. An integrated safety torque off (STO) feature has emergency stop capabilities up to SIL 3/PLe when used with a suitable safety relay or safe PLC.
