The CONTACTRON Speed Starter offers the critical functions common in a variable frequency drive (VFD) without the complexities. The device requires no drives expertise or software, making it fast and easy to commission. The Speed Starter provides ramp-up and ramp-down functions while the motor is under load, which a soft starter cannot. Unlike a traditional motor starter, it offers two independently settable operating speeds.
The intuitive keypad and rotary knob allow commissioning in just 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. The Speed Starter also streamlines safety. The 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. The Speed Starter is ideal for intralogistics applications such as conveyor and material handling systems.
