Adjustable Frequency Drives

Wed, 10/19/2011 - 6:00am

The IMPULSE Series 4 Adjustable Frequency Drives from Magnetek, Inc. (Menomonee Falls, WI) can be used as an open-loop vector or V/F crane control for traverse motions or mechanical load brake hoists. The drives offer Load Check II, which continuously detects hoist overload conditions throughout the frequency range, halting upward motion and only allowing the load to be lowered. The Adaptive Ultra-Lift feature allows for hoist operation above base speed with a light load or empty hook. Safe Torque Off provides a redundant hardware safety circuit that guarantees motor and brake power are removed when a safety controller opens the drive input, eliminating the need for external disconnects.
