Magnetek, Inc. (www.magnetek.com) has introduced its latest IMPULSE® Series 4 Adjustable Frequency Drives, which continues the company’s tradition of providing the most cost-effective and reliable adjustable frequency crane control in the market, said Dan Beilfuss, Director of Sales at Magnetek.
The IMPULSEoG+ Series 4 can be utilized as a V/F crane control or as an open-loop vector for mechanical load brake hoists or traverse motions, while the IMPULSEoVG+ Series 4 can be utilized as a closed-loop flux vector crane control for high performance traverse motions and non-mechanical load brake hoists.
Beilfuss said that IMPULSE Series 4 drives integrates innovative control and safety features, such as Load Check II, which continuously monitors the frequency range’s hoist overload conditions and halting upward motion, while enabling the load to be lowered.
The latest Adaptive Ultra-Lift feature — which Magnetek has a patent pending — permits for hoist operation above base speed with an empty hook or light load. It constantly monitors motor torque while adjusting motor speed, allowing it to operate at peak performance to optimize plant safety and throughput. The Safe Torque Off feature eliminates the need for external disconnects as it offers a redundant hardware safety circuit to ensure that brake and motor power are removed when a safety controller or an E-STOP switch opens the drive input.
“We are excited to provide our customers with the advanced technology of the IMPULSE Series 4 line of crane controls and want to remind them that every IMPULSE drive is backed by Magnetek’s unsurpassed three year warranty,” quipped Beilfuss.
