Customers often ask us how easy it is to replace their existing variable frequency drive (VFD) with a Magnetek IMPULSE VFD. The answer is: it’s easy!
Whether you have an existing VFD from decades ago, or even contactor control, you can get a replacement Magnetek VFD up and running in only a few steps.
STEP 1: Selection
Selecting an IMPULSE VFD is as simple as matching it to the motor. Using the motor nameplate data (e.g. voltage, FLA, etc.) and details of the crane, such as the motion and duty cycle, the experts at Columbus McKinnon will provide the most cost effective and optimal VFD controls for your application.
STEP 2: Connection
Magnetek VFDs can be configured to accept any wiring requirements in the field without needing changes. Whether the speed control is stepped or stepless, the necessary inputs and outputs, such as digital, analog, or even serial communications, can be provided.
STEP 3: Configuration
1: Install the VFD. Simply mount the VFD and determine the new landing spots for the power and control wires. A quick start guide and detailed technical manual are readily available to make this process quick and easy.
2: Choose how you want the VFD to be controlled, whether it is stepped, stepless, or analog. This marries it to the pendant or radio control you will be using.
3: Program the VFD. Magnetek VFDs make programming easy. First, select which part of the crane the VFD controls. Then, configure the VFD for that motor. The auto-tuning feature makes this process essentially automated. If desired, you can tweak the speeds, acceleration and deceleration rates, and any crane-specific features you require.
This online course includes discussions of basic principles and operation of Magnetek’s industry-leading IMPULSE® AC variable frequency drives for crane applications.

When comparing variable frequency drives (VFD) to 2-speed control for use in cranes and hoists, there are a variety of factors you should take into consideration. These range from load control and speed adjustment to efficiency and extended hoist life. In this blog, we will compare the two to show you the benefits of VFD crane control over 2-speed.
When choosing a variable frequency drive (VFD) for your crane or hoist application, we recommend using a crane-specific VFD and not a general purpose VFD. Why? Using a crane-specific VFD can have a significant impact on the safety, uptime, and productivity of your crane application, and can get you up and running quicker and easier.
