The OS10 series offers an excellent price-performance ratio. The drivers are mountable through 4 holes placed on the corners of the board. The connection of the signal and power cables is through screw terminal blocks suitable for 2,5mm2 wire size.

The diagnostics are accurate and the setting is quick and simple thanks to the graphic software UDP Commander designed for Windows platform.

The many setting options available allow to use the drivers with many kinds of motor and applications. For example, it is possible to set each input to operate in true or negate logic, to set the automatic current reduction time and percentage, etc.

The reduced cost, due to the open frame construction, makes these driver the ideal choice for volume OEM applications.
