DC motor control Stepnet ST3-055-04

stepperCANopenRS-232

Stepnet ST3-055-04 puts three stepper motor drivers in a 13 in² package that combines CANopen networking with 100% digital control of stepper motors. Each axis is programmable with a unique CAN node address, which is stored in flash memory. Power output is compatible with most NEMA 17 and 23 size stepper motors. The small footprint is well suited for desktop instrumentation and enables motor drive, interface, and control circuits to be combined on a single PC board.

CAN address selection is programmed into driver flash memory. As a CANopen node Stepnet ST3-055-04 operates as a Motion Control Device under the DSP-402 protocol of the CANopen DS-301 V4.01 (EN 50325-4) application layer. DSP-402 modes supported include: Profile Position, Interpolated Position (PVT), and Homing. Profile Position Mode does a complete motion index on command with S-curve acceleration & deceleration, top speed, and distance programmable.
