Upgrading from the Unidrive SP to the M700

SP to M700 upgrade

Upgrading from the Unidrive SP to the M700 is easy and straightforward. The M701 drives from the M700 series are designed as the direct upgrade path for the Unidrive SP and there are a range of tools to make installation quick and easy.

Designed specifically to replace the SP - exact same out number of programmable inputs and outputs with the same default out of the box configuration.

All of the same great features of the Unidrive SP but with enhancements, for greater stability, protection and robustness.

The M700 drives are the same size or smaller than their SP counterparts with mounting adapters available to match the SP mounting holes so there is no drilling necessary.

The free Unidrive M Connect software automatically converts your Unidrive SP parameter set to be loaded into the M700. You can also use a Smartcard to transfer parameters from an SP to an M700.

How to find your M700 part number

You can find the part number for your M700 drive on the side of the unit. The M700 part numbers follow a particular format, for example M700-034 00025 A with each part of the number indicating something different about the unit, such as the frame size, voltage rating and current rating.
