Driver LW3A9030N2A1-00

Description Driver LW3A9030N2A1-00

Functions

● Setting of the current value by means of dip-switches

● Selection of the step angle by means of dip-switches or serial service SCI interface. In order to maintain compatibility with traditional drivers, step angles have been emulated through software, the current regulation is always sinusoidal.

● Possibility to select four user functions:

1 - Reading the motor BEMF, LW3 drivers detect without encoder the step loss, showing alarm status with the Fault digital OUT and a LED sequence.

2 - Step/Direction or Clock-Up / Clock-Down control mode.

3 - enable input management (safety control).

4 - automatic current reduction via software (still motor).

Main Features

● Mains 230 Vac power supply

● Sensorless motor stall detection

● Built-in Service Serial Interface for parameters configuration and debugging via software

● Protections against short circuit motor, open phases, over/under voltage and temperature

● Vectorial control: the sinusoidal phase current with “else” technology keeps the motor torque constant allowing smooth and noiseless movements.

● Smooth movement

● Noiseless rotation

● Low EM emissions

● Software resonance damping

● Reduction of motor’s temperature

SOFTWARE KIT FOR CONFIGURATION

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 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.

Functionalities

The sinusoidal phase current with “else” technology keeps the motor torque constant allowing smooth and noiseless movements.

Connections/Control

Connection for the parameters configuration is made through SCI service serial interface and the software tool Ever Studio that allow easy and quick configuration, a real time debug and a supervision of each system.
