DC Servo Drive

The UM/UL series from Baldor is a DC servo drive providing control for a wide range of Baldor DC servo motors such as the M3300, M4000, and M4500 motors.

Providing 600 watts thru 2.25 Kw, the UM comes in models providing 6 amp and 15 amp continuous, with peak currents of 15 and 30 amp. The UM is a fully protected unit and has protection against over voltage, surge current, over temperature, ground faults and logic fault.

The UM is an open chassis multi-axis configuration, typically containing one to six control cards which are inserted onto the chassis. The chassis includes the power supply and associated hardware.

Easily interfaces with today’s motion controllers, the UM accepts the industry standard +/- 10 Vdc input command, tachometer feedback, and will operate in either velocity or current mode.

A version/model of the UM is the “LD” series that accepts 115 Vac direct, providing 160 Vdc bus. It is available in 1 or 2 axis.
