Functions
● Motor parameters selection via roto-switches configurable via software
● 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 the following user functions:
1 - Step/Direction or Clock-Up / Clock-Down control mode.
2 - Reversal of motor rotation.
Main Features
● Closed loop of torque, speed and position via incremental encoder
● Integrated diagnostic
● Protections against short circuit motor, open
phases, over/under voltage and temperature
● Vectorial control: the sinusoidal phase current with “else” technology keep
the motor torque constant allowing smooth and noiseless movements.
● Smooth movement
● Compact size
● Noiseless rotation
● Reliability
● Low EM emissions
● Software resonance damping
● Auto tuning of motor control parameters
● High efficiency current set up
● Reduction of motor temperature
● Digital IN 5 - 24 Vdc
● Quick and easy installation

| SW4_SERV00-SL | Kit software for drive configuration with Ever Studio + 200 cm serial cable and serial/USB converter |
LW4 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”. Furnished an incremental encoder input with which it is possible to control the motor in closed loop of torque, speed and position.Completely digital and made using Arm Core M4 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.
