Soft starter controls acceleration
April 2009
Motion Control & Drives
Starters are maturing as more sophisticated units perform soft start and stop functions with greater control, more protection and detailed feedback. The latest release from CHI Control Components, the AuCom EMX3 is more than a starter; it is a complete motor management system.
The EMX3 introduces a new generation in soft start technology: XLR-8, adaptive acceleration control. XLR-8 has an unprecedented level of control over a motor’s acceleration and deceleration profiles. Using XLR-8, the soft starter learns the motor’s performance during start and stop, then adjusts control to optimise performance.
The EMX3 is smart and dependable, with new design features for quick set-up and more customised control.
Easy to use
While soft starters are becoming increasing feature-rich, AuCom has taken steps to ensure that commissioning, operation and fault finding are still quick and easy. Quick setup mode gets machinery running in next to no time, and informative screens advise the operator on motor performance.
Compact and versatile
EMX3 Soft Starters are among the smallest in their class, saving installation costs by minimising panel space requirements. The design of the EMX3 allows for multiple units to be mounted side by side, or in a bank of starters due to the flexibility in cabling options. Internally bypassed starters further reduce the overall size of the soft starter.
The starter has been designed for maximum flexibility in a wide range of industries. Whether it needs to integrate into a network or respond to external signalling equipment, or there is a requirement for reliable motor protection, the EMX3 offers the features needed in a reliable product.
Applications
XLR-8 is ideal for low inertia loads such as pumps and conveyors, and can substantially reduce or eliminate the effects of water hammer. In addition to this the EMX3 is suitable for high inertia loads including circular saws and ball mills as XLR-8 allows precise control over the motor’s stopping time. It is also suitable for pumping (high head applications); compressors (optimised blade control); band saws (blade alignment) and irrigators (built-in timer).
