The 1240i is a stand-alone programmable step motor
driver suited for a wide range of motion
control applications. It includes a
sophisticated controller integrated with a
48-watt microstepping amplifier. The 1240i
includes easy to use software for the rapid
development of stand-alone motion control
programs. The 1240i can also be
commanded in real time from a host PC or PLC, using the Si Command Language (SCL).
SCL allows for control via serial commands sent from a host device such as a PC or PLC. This permits the user to perform a variety of motion, I/O, and system
status tasks in real time via a host serial device.
For multi-axis applications, up to four drives
(stepper or Servo) can be networked using a
single SiNet Hub 444. The 1240i includes
8 optically isolated programmable inputs for
triggering, branching, position sensing and
end of travel detection. 3 optically isolated
programmable outputs can send signals to
other electronic devices and activate relays.
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
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
