Description
Miniature Digital DC Servo Drive Controller for Extreme Environmental Conditions
Ultra – light and intelligent digital servo drive
Operating Modes-Current, Velocity, Position & Advance Position
The Bee is a highly durable series of featherweight ExtrIQ digital servo drives for DC brush and brushless motors, linear motors and voice coils. Despite weighing only .95 oz (27 g), the Bee can withstand extended environmental conditions and support up to 3.3 amps continuous current. Its high density allows the drive to deliver a peak of 400 W of power and 200 W of continuous power.
Based on Elmo’s SimplIQ Motion Control technology, the Bee is capable of operating in position, velocity and current modes and contains a wide range of feedback and I/O options. By using Elmo’s Composer software, users can easily perform drive setup, configuration, tuning, analysis and programming. The drive operates on DC power. The Bee is a PCB mounted device that enables an efficient and cost saving implementation.
Mating Power Supply ELP-30.
