With 35+ years of repairing industrial automation parts there’s not many drive problems we haven’t encountered. As an official Integration Partner our engineers have been factory trained by Control Techniques and we have test rigs in place to fully test the Unidrive SP inverters for the highest quality repairs around. All of our variable speed drive repairs come with a 2 year warranty and our no fix no fee promise.

Control modes

Control modes

The Unidrive SP has five different control modes making them suitable for a wide range of tasks and applications. Open loop motor, closed loop motor, servo motor, linear motor and regenerative active front end are the main control modes. Additional options such as I/O modules and feedback further expand their capabilities.



The Unidrive SP inverter drives have a wide range of error codes that will display on the LCD keypad should an error occur with your variable speed drive. You can find a more information about each error code in the drive manual in the PDF and downloads section. Alternatively you can give us a call and we will do our best to resolve this with you over the phone.

Upgrading from the Unidrive SP to the M700

Upgrading from SP to Unidrive M

The Unidrive M700/M701 is the direct upgrade path for the Unidrive SP and has been designed by Control Technique to be an easy, straightforward replacement.

Compatible physical dimensions, weights and surface mount footprint

There’s no need for any additional drilling when you retrofit the M700 range - existing mounting holes can be reused and mounting kits are available for drives which are smaller.

Power and control wiring are done in the same way as the Unidrive SP

The same menu and parameter structure is used by the Unidrive M range

Parameters are transferable from the Unidrive SP to the Unidrive M with the free M Connect software

How to find your Unidrive SP part number

The easiest way to find a replacement Unidrive SP is to search your part number on our website. Usually you can find the part number located underneath the keypad on the front of the drive. The part number is typically six digits long and will begin with the letters SP.
