The 3540i is a programmable step
motor driver suitable for a wide range of
motion control applications. It includes a
sophisticated controller integrated with a
140 watt microstepping amplifier. The 3540i
includes Applied Motion’s easy to use Si
Programmer™ Windows software for the
rapid development of stand-alone motion
control programs. The 3540i can also be
commanded in real time from a host PC or
PLC, using the Si Command Language™.
For multi-axis applications, up to 4 of
our “Si” or “i” drives (stepper or Servo)
can be networked using a single SiNet™
Hub 444. The 3540i 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.
