Functions
● Setting of the current value by means of dip-switches
● Selection of the step angle by means of roto-switches.
In order to maintain compatibility with traditional drivers,
step angles have been emulated through software, the current
regulation is always sinusoidal.
● Possibility to select user functions:
1 - Step/Direction or Clock-Up / Clock-Down control mode.
2 - Enable input management (safety control).3 - 30% or 70% automatic current reduction (still motor).
4 - enabling of “Clock Test” function, useful during the
driver’s installation, which shows the right presence
of the clock signal through status LED flashing.

SOFTWARE KIT FOR CONFIGURATION
| Code | Description |
| LW3_SERV00-SL | Kit software for drive configuration with Ever Studio + 200 cm service serial cable and serial/USB converter |
LW3 is a new line of
vectorial drives belonging to the Titanio family, characterised by innovative performance. Built by integrating the
new ‘Else - Error Less Servo Efficient technology’, with the accurate control of the sinusoidal current, these drives allow to command stepper motors with a drastic noise reduction, less heating and extremely smooth movements. Suitable for driving 2-phase hybrid stepper motors, they can be coupled mainly with the series of motors from 0.8” to 3.4”.
Completely digital and made using Arm technology, LW3 drives offer exceptional reliability combined with mechanical compactness and a competitive price.
They can be used in many types of machines where there is already a controller for the generation of digital clock & direction signals, such as X-Y tables, labelling machines, laser cutters, pick-place devices, engraving tables, etc. and they are recommended in all applications in which not only versatility, precision and speed are required, but also smooth and silent movements as in the medical field.
