AC Servo Drives include 8, 16, and 24 A models.

Press Release Summary:

Series MB2 can be configured for low or high inductance servomotors. Units rated 8 and 16 A operate from 40-220 Vac, while 24 A model operates from 40-120 Vac. All drives can operate in current, velocity, or position mode. They include LEDs for status and diagnostics, fully isolated power stage, and I/Os that are TTL/CMOS or opto-isolated. If Over-RMS condition is reached, drives can be set to shut-down or roll-back to RMS current setting and continue operating.

Original Press Release:

The MB2 AC Series of Servo Drives

Chatsworth, CA - An all-new series of low cost, user friendly, compact, servo drives has features that let brushed DC servos out perform higher priced brushless servos. The MB2 AC Series of Servo Drives has been designed by Servo Dynamics to give high performance at lower cost. Three models (8, 16 and 24 amp continuous) are easily configured for low or high inductance servomotors. The 8 and 16 amp drives are designed to operate from 40 VAC to 220 VAC and the 24 amp drive from 40 to 120 VAC. For greater throughput the 8 and 16 amp drives have switch selectable peak currents of 2 or 3 times the continuous current. For use with smaller servomotors, the 8 amp model is switch selectable to 4 amp continuous with no loss of resolution.

MB2 AC drives incorporate the latest in digital and analog circuitry for performance and reliability. The MB2 AC drives can operate in current, velocity or position mode. Velocity mode feedback options are: Tachometer, encoder or sensorless, and the position mode accepts either pulse-and-direction or pulse-up and pulse-down command inputs. The MB2 drives are equipped with LEDs for status and diagnostics. Other features include: a fully isolated power stage and I/O's that are TTL/CMOS or Opto-Isolated. Also, if an Over-RMS condition is reached, these drives can be set up to either shut-down or roll-back to the RMS current setting and continue operating. The MB2 AC Servo Drives are UL and CE compliant.

Servo Dynamics located in Chatsworth, California designs and manufactures high performance servo control systems and is committed to total customer satisfaction. Servo Dynamics is a registered ISO 9001:2000 supplier.
