Servo Motor Controller features sample rates to 20 kHz.

Press Release Summary:

Intended for up to 100 W brush motors with quadrature encoders, 3C20 digital motion controller includes 30 MIPS, 16-bit DSP coupled with 100 W Hbridge on single 2 x 2 in. card. This single-axis dc servo motor controller/amplifier features profile generator with built-in trapezoidal profile capability. Position, velocity, and acceleration/jerk parameters all have 32-bit or greater precision. Dual FIFO buffered interface allows real-time and queued commands to proceed simultaneously.

Original Press Release:

NEW! 3C20 100W Smart Servo Motor Controller

The 3C20 digital motion controller is a DSP based single-axis DC servo motor controller/amplifier intended to control small (up to 100 W) brush motors with quadrature encoders. The 3C20 includes a 30 MIPS 16 bit DSP coupled a 100 W Hbridge on a single 2"x2" card.

Position, velocity and acceleration and jerk parameters are all have 32 bit or greater precision. Profile generator has simple built-in trapezoidal profile capability . Elaborate time based S-curve profiles are easily generated with a sequence of jerk values and delay tokens place in one of the FIFOs.

High sample rates (~20 KHz) support small and fast drive systems. Software selectable current (torque) or voltage mode motor drive.

The 3C20 host interface is a RS-422 or RS-485 serial port that supports baud rates up to 1.84 MBaud. Efficient dual FIFO buffered interface allows real time and queued commands to proceed simultaneously. Price of the 3C20 is $54 in 100's.
