Replacing an Existing Variable Frequency Drive with a Magnetek® IMPULSE® VFD

How To's | Power & Motion Technology | Crane Systems | By Casey Cummins | May 21, 2021


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.
