Magnetek G+ Series 4 Features

• 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.
• 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.
• Adaptive Ultra-Lift™ allows for hoist operation above base speed with a light load or empty hook. Adaptive Ultra-Lift continuously monitors motor torque and adjusts motor speed to operate at peak performance, improving plant safety and maximizing throughput.
• Brake Test verifies brake torque with the press of a button, capturing breakaway torque with a monitor parameter on the keypad.
• Anti-Shock automatically stabilizes loads by detecting and minimizing rapid increases in motor torque, thus reducing the potential for crane damage caused by operator induced load shock.
• Quick-Set™ is provided by the easy-to-use keypad and X-Press Programming™ so you get up and running right away.
• Safe Lifting features are built right in, including Torque Proving, which confirms the motor is providing enough torque to safely lift a load prior to releasing the brake.
• Option Cards provide the drive flexibility needed with expandable AC digital input and output, DC digital and analog input and output option cards.
• IMPULSE Link Diagnostic System – maximizes the efficiency of your drive by providing easy parameter management right on your PC.
• IMPULSE G+ drives are compatible with 50HZ voltage making them available for use in all European countries.
