Mclennan Servo Supplies has launched a range of microstepping drives from Applied Motion Products.

The flexible STAC5 series features advanced algorithms for extended dynamic performance and flexible motion-control options including a choice of step and direction, PC or PLC host control and full-featured multitasking programmable control.

The compact panel-mount STAC5 series is designed for straightforward integration into motion-control systems with direct-online power at nominal voltages of 120 and 220V AC with a maximum of 5A per phase to suit 23- and 34-frame NEMA stepper motors.

A 100Mbit Ethernet communication port is included to configure the drive with self test and auto setup, as well as support streaming of individual commands or full program upload and download.

An encoder feedback option is also available that provides position verification and combines with a stall-detection and stall-prevention feature that allows selectable levels of position maintenance.

The STAC5 has a number of current control features that help deliver improved motor performance.

The Anti Resonance algorithm improves midrange stability, allowing higher speeds, faster settling times and improved torque, while Torque Ripple Smoothing greatly improves low-speed dynamic performance.

The Command Signal Smoothing algorithm reduces jerk, which can help reduce wear on mechanical transmission components.

In addition, the Microstep Emulation feature converts low-resolution step pulses from a controller into microsptep resolution pulses at the motor, vastly improving smoothness.

The STAC5 series is available with a choice of two controller options.

The S controller allows step and direction interfacing from any third-party controller and can also be software configured for run-stop operation where built-in analogue and digital I/O can toggle speeds or provide a joystick control interface.

The S controller and the more powerful Q controller will both accept serial commands over Ethernet from a PC or a PLC for multi-axis control.

For full standalone programmable control, the Q controller uses Applied Motion Product’s Q language with features that include multi-tasking, conditional programming and maths functions.

The Q version is able to download, store and execute programs from a host or directly from the Q Programmer GUI, which allows straightforward motion and machine I/O programming from a PC.

The S controller includes four digital inputs, two digital outputs and one analogue input.

The Q controller has 12 digital inputs, six digital outputs and one analogue output.
