Copley Controls: CANopen Stepper Motor Driver Stepnet 3-Axis (ST3-055 Series)

20-75 VDC & 115-230 VAC Digital Drives for Stepper Motors

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.

Setup is fast and simple using CME 2™ software operating under Windows® and communicating with Stepnet ST3-055-04 via an RS-232 link. 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.

In PVT mode, the controller sends out a sequence of points each of which is an increment of a larger, more complex move than that of a single index or profile.

Digital logic inputs are programmable as limit & home switches, stepper pulse inputs, A/B master encoder, reset, motion abort, or motor over-temperature. There are six programmable logic outputs for reporting a driver fault, or other status indications. When operating as a CAN node, inputs and outputs can be used as general-purpose i/o with no link to amplifier functions.

An Aux HV input is provided for “keep alive” power that preserves the driver data (e.g. current position) and CANopen operation if +HV has been removed as in an emergency-stop situation. This enables the control system to monitor drive status and to enable an orderly recovery without a full system reset, and “homing” of all axes. operation from transformer-isolated DC power supplies saves cost in multi-axis systems.
