MAGNETEK IMPULSE AC Electric Motor Controls

INDUSTRY-LEADING PERFORMANCE FEATURES COMBINE WITH
OUR SUPERIOR APPLICATION EXPERTISE TO PROVIDE UNMATCHED PERFORMANCE.

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.  Safety features are integrated into every drive,
preventing harm to the crane structure and crane equipment, and most importantly, creating a safe working environment for operators.  Magnetek’s IMPULSE•G+/VG+ Series 4 drives continue our tradition of providing the most reliable and costeffective
adjustable frequency crane controls available. With hundreds of thousands of drives in operation backed by decades of experience, IMPULSE drives are the smart choice.

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, meeting the requirements of IEC/EN 61508.  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. For example, motor speed can now be increased automatically when a magnet releases a load or gear ratios change with overwrapping drums. BRAKE TEST verifies brake torque with the press of a button, capturing breakaway torque with a monitor parameter on the keypad. This valuable tool determines the condition of the brake so you can perform preventative maintenance and quickly commission the crane.

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-SETUP™ is provided by the easy-to-use keypad and X-Press  Programming™ so you get up and running right away. X-Press Programming automatically configures several commonly used parameters and features when a control

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. Torque Limiting prevents the crane from performing a lift that could overload the motor and cause mechanical fatigue. Brake Integrity Check tests the primary and emergency brakes to ensure they are mechanically capable of holding the load.

OPTION CARDS provide the drive flexibility needed with expandable AC, DC digital and analog input and output option cards. Simplify automation and diagnostics integration with our EtherNet/IP, Modbus TCP/IP, PROFIBUS-DP, and PROFINET option cards. The new control power supply option maintains drive diagnostics, I/O, and communications when main power is disconnected from the drive.

IMPULSE•LINK DIAGNOSTIC SYSTEM maximizes the efficiency of your drive by providing easy parameter management right on your PC. IMPULSE•Link can communicate with up to 31 drives locally or wirelessly, allowing drive diagnostics, monitoring, and programming. ENERGY ENGINEERED™ motion control products
from Magnetek are designed to efficiently utilize available power, reducing energy costs for you and your customers. 

RELIABILITY Magnetek drives are designed with reliability and economy in mind. The hardware and software were designed and extensively tested specifically for the operating conditions seen in overhead material handling applications.  These durable drives feature new power modules that can withstand four times more thermal cycles than previous generations. Preventative maintenance monitors provide the feedback you need to proactively schedule maintenance and minimize downtime. IMPULSE•G+ & VG+ Series 4 drives are backed by our industry-leading three-year warranty.method, motion, or speed reference is selected.
