What is a General Purpose Variable Speed Drive?

We’re committed to providing the very best variable speed drives for every application, and with our general purpose VSDs we make no exception. We designed each general purpose variable speed drive in our range to be suitable for purpose, backed by in depth customer research. This means we offer the most basic AC motor control found on simple conveyors, as well as solving the world’s most complex motor control problems.

What is a General Purpose Variable Speed Drive?

General purpose VSDs make it possible to control the speed of a motor by variating the frequency and voltage of the signal going into the motor. They differ from high performance AC drives in two ways:

Simple to setup variable speed drives

Our general purpose VSDs don’t require a specialist to install them. In fact, we designed them to be quickly installed with little or no training. Parameter settings are clearly labelled on the drive, and laid out on the keypad in a way that makes setup easy.

For engineers working onsite, our webpage www.drive-setup.com contains setup videos and fault diagnostics, to get you up and running in minutes. If you batch build, VSD setup takes seconds by using a backup adaptor (and 24 V).

AC drive performance you can rely on

If we’re talking world class motor control, then you’ll know that’s what we’re famous for. In simpler applications we understand you just need the right tool for the job. But still, it’s good to know that our general purpose AC drives work on the same technology as our flagship M700 series. That means you can say goodbye to site revisits; our drives are made to last.

General Purpose VFDs designed for all your automation needs

From the moment they are switched on, our drives are ready to go. Simple to set up. Accurate. Flexible to your needs.

We're here when you need us. Made with distributors in mind. Less stock.
