Stepper controller tackles demanding applications

A JVL Industri Elektronik product story
Edited by the Engineeringtalk editorial team Oct 7, 2003

The SMC35 is JVL's new stepper motor controller, offering high torque, high velocity and high resolution to solve the most demanding applications.

The SMC35 is JVL's new stepper motor controller, with a built-in micro-PLC, 11 inputs and eight outputs, two analogue inputs and one analogue output.

The controller offers high torque, high velocity and high resolution in order to solve the most demanding applications in the industry.

Programming is accomplished from a PC using JVL's Windows-based software MotoWare, which ensures quick and easy setup, programming, and running in of a system.

Two built-in microprocessors ensure true multitasking with change of velocity, acceleration, outputs etc while the motor is running.

The controller additionally includes advanced timers, counters and interrupt facilities so that any task can be solved.

An encoder input enables motor position and "stall" to be detected so that corrective measures can be taken.

An external step and servo driver with pulse/direction can be connected so that 1.5-axis movement can be performed.

The SMC35 offers fast, 20kHz switching, recirculating digital current control, anti-resonance circuitry and software selection of current, step resolution, velocity etc.

It is protected against short-circuiting motor phases and outputs.

It offers selection of mini-step resolution, where each mechanical full-step is divided into many fine small steps (one, two, four or eight ministeps per full step).

This gives better motor operation at low speeds, lower noise, resonance-free operation and finer resolution.

Using a fieldbus interface, it is possible to connect peripheral equipment such as a keyboard/display, extra I/O modules etc.
