The ST-series performance stepper drives incorporate advanced
features that will derive the highest performance from today’s stepper
motors. The Anti-Resonance and Waveform Damping control algorithms
make this drive a clear market leader. The "-S" models are step and direction drives,
compatible with PLCs which feature high-speed pulse output, such as our ELC-PLC series and OCS XL series.
The "-Si" models are stand-alone programmable drives which are programmed with the
simple-to-use Si Programmer software.
Some of the advanced features of the ST-series drives include:
Self Test and Auto Setup: At start-up the drive measures
motor parameters, including the resistance and inductance, then uses
this information to optimize the system performance. It also compares
this information from the last configuration and checks to see if the motor
data has changed (this could indicate a fault or system change). The
drive can also detect open and short circuits.
Anti-resonance: A disadvantage of the step motor is a tendency
to "resonate" at some frequency. By entering some system data this
natural frequency can be calculated and a damping term entered into
the control algorithm. This significantly improves midrange stability and
allows higher speeds and more use of the available torque.
Command Signal Smoothing: Dynamic smoothing can
soften the effect of immediate changes in velocity and direction, making
the motion of the motor less jerky. An added advantage is that it can
reduce the wear on mechanical components.
Torque Ripple Smoothing: All step motors have an inherent
low speed torque ripple that can affect the motion of the motor. By
analyzing this torque ripple the system can apply a negative harmonic
to negate this effect, giving the motor much smoother motion at low
speed.

Introduction to Stepper Motors and Drives
Si Programmer
Intended for use in stand-alone applications, Si (Simple Indexer) Programmer
provides quick, out-of-the-box use with an extremely friendly, point-and-click
graphical interface that does not require any software programming experience.
Once an Si program has been constructed and downloaded to the drive,
the program can be executed stand-alone at power-up or from an external trigger.
Constructing a program is accomplished through the use of instructions selected
in a point-and-click manner. Once an instruction is selected, a "fill in the blanks"
format is used to input parameters.
Constructing an Si program requires no prior programming experience nor does
it require learning a programming language. Si Programmer generates the actual
motion control program, based on user selected parameters, thereby eliminating
syntax errors. Once created, programs are easily downloaded, uploaded, saved
and printed.
Si Programmer also provides the capability to control digital inputs and outputs,
useful for interfacing with external equipment like PLCs, sensors, end-of-travel switches,
and more. Si Programmer has found success in all types of applications, from simple
linear actuator applications to complete machine control with operator interface
applications.
