 PicoSTP

PicoSTP is a simple, user-friendly and flexible stepper motor driver suitable for medium and low power, applications.

PicoSTP is the right choice for all applications where the small dimensions and best cost/performances ratio are important.

The board can operate between 12 and 40V and nominal current up to 1.6A in 8 micro-switch selectable levels; it also contains a useful built-in oscillator with analog input to self generate the step signal.

APPLICATIONS

  • Positioning systems
  • Automatic machinery
  • Servosystems
  • Robots
  • Axes control

GENERAL SPECIFICATIONS

  • Low-power, reliable and efficient stepper motor driver with voltage up to 40Vdc and nominal current up to 1.6A
  • Convenient cost/performances ratio
  • Configuration by means of dip-switches
  • Opto-coupled inputs
  • Small size (125 x 60 x 50 mm)
  • Shortcircuit protection
  • Leds for operative conditions indication
  • Current auto-reduction function on stand-still (escludible)



 TECHNICAL CHARACTERISTICS
Supply voltage
min. 12Vdc max 40Vdc.

Phase current
8 micro-switch selectable levels from 200mA up to 1.6A/phase.
Current auto-reduction function on stand-still. Chopping 20 kHz chopping frequency.

Resolution
HALF or FULL step selectable by means of a microswitch.

Motor types
For stepper motor with 4,6 or 8 windings in serial or parallel mode.
Configurable for high and low inductance motors.

Oscillator
Built-in oscillator with external trimmer regulation (up to 6000 pps).

Inputs
Opto-coupled inputs.
