Bassoon

The Smallest Power-Packed Servo Drive Controller

AC powered for DC, rotary, linear and brush or brushless motors

Up to 1.9 kW of continuous power compressed into a compact
12 oz (350 gr) case

The Bassoon is a series of intelligent digital servo drives for DC brush, brushless motors and linear motors. The servo drive supports up to 6 amps continuous current. Its high density allows the drive to deliver
1900 W continuous power and 3800 W peak power. Based on Elmo's SimplIQ Motion Control technology, the Bassoon is capable of operating in position, velocity and current modes and contains a wide range of feedback and I/O options. With Elmo's Composer software, users can easily perform drive setup, configuration, tuning, analysis and programming. The drive operates on AC power. The Bassoon's compact case enables efficient and cost saving implementation.
