The Next Generation of Crane Performance
Magnetek’s IMPULSE•VG+ Series 4 drives continue our tradition of providing the most reliable and cost-effective adjustable frequency crane controls available. With hundreds of thousands of drives in operation backed by decades of experience, IMPULSE drives are the smart choice.
IMPULSE drives are designed especially for material handling applications, providing a complete package of crane-specific capabilities far beyond a general purpose drive's functionality. The IMPULSE•G+ Series 4 can be used as an open-loop vector or V/F crane control for traverse motions or mechanical load brake hoists.
Industry-leading safety and performance features combine with our superior application expertise to provide unmatched performance.
Load Check II™ continuously detects hoist overload conditions, halting upward motion and only allowing the load to be lowered. Load Check II continuously monitors the hook load, both during acceleration and constant speed, eliminating the need for load cells in most applications. It provides an auto-setup function which defines the hoist’s maximum hook load in seconds. With these control advancements, the drive no longer pauses for tests unless rated capacity is approached, providing increased productivity.
Safe Torque Off provides a redundant hardware safety circuit that guarantees motor and brake power are removed when an E-STOP switch or safety controller opens the drive input, eliminating the need for external disconnects. This functionality is provided in a safety category 3 architecture and designed to PLd and SIL CL2 according to ISO/EN 13849-1 and IEC/EN 62061 respectively
