Vectorial drivers for 2 phases stepper motors
2Pages

Main features √ Vectorial control The sinusoidal phase current with “else” technology keep the motor torque constant allowing smooth and noiseless movements. Vectorial drivers for 2 phases stepper motors STEP & DIRECTION Power supply Motors type OPTO ISOLATED INPUTS 4 Digital IN 2 ÷ 24 Vdc NPN, PNP or Line-Driver 2 MHz OPTO ISOLATED OUTPUT 1 Digital OUT 24 Vdc - 100 mA for status monitoring STEP RESOLUTION From full step up to 1/256 (emulated) SAFETY PROTECTIONS Over/Under voltage, Over Current, Over Temperature, Short Circuit Phase/Phase and Phase/Ground TI T A N I O VECTOR - STEPPER - DRIVES ● Setting of the current value by means of dip-switches HUMIDITY 5% ÷ 85% PROTECTION CLASS IP20 ● 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. 1.8° (1/4 microstep of traditional type) ● Equipped with advanced safety features: √ Sensorless motor stall detection √ Integrated diagnostic √ Protections against short circuit motor, open phases, over/under voltage and temperature LW3 drivers of Titanio series, based on Arm Core M4 technology, are the solution to control stepper motors in clock&direction mode with an accuracy, smoothness and noiseless never seen before for a stepper driver. Titanio drivers ● Possibility to select five user functions: 1 - enabling of motor stall detection. 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 - 30% or 70% automatic current reduction (still motor). STATUS MONITORING 3 LED with guiding light (green and red/yellow) TEMPERATURE Working: from 0°C to 40°C. Storage: from -25°C to 55°C ELETTRONICA PER AUTOMAZIONE INDUSTRIALE Via del Commercio, 2/4 -9/11 Loc. S.
