SD Azionamenti Enhanced Description: The SDL drive series are Full Digital high performance microstep devices based on the precise pwm control technology to regulate the sinusoidal current. Thanks to this solution the SDL drives are able to control stepper motors through digital step, direction, rating and starting current signals with less noise, less heating and smooth motion in open as well as in closed loop of torque, velocity and position. Designed for the control of 2 or 4 phase hybrid stepper motors, a wide range of stepper drives with a different power level are available to be used with motor series from 1.7” to 4.2”. The SDL drives offer reliability and first-class performances and can be used in many types of machines such as such as X-Y-Z tables, laser cutting systems, pick & place devices, etc. They are suitable for use in applications that require a high precision, speed and easiness of use.

Specifications: Power stages: 40 kHz H-bridge Bipolar chopper. Optically isolated inputs: up to 8 digital optoisolated inputs 5 Vdc line driver or 24 Vdc NPN or PNP(200 kHz). Optically isolated output: 8 digital optoisolated output 24 Vdc – 100 mA (700 mA for 170 models). Step resolution: from 1 to 128 micro steps. Safety protections: over/under-voltage, over current, over temperature, open windings, closed windings phase/phase phase/ground. Drive Status Monitoring: seven segments LED display. Temperature: working temp. 0°C÷50°C, storage temp. 0°C÷55°C Humidity: 0%÷90%. Protection class: IP20. Control modalities: digital tracker: The Digital Tracker mode enables unlike the Step & Dir mode, also the tracking of an external analog signal and the complete parameterization of the drive by means of serial RS232. Besides the drive’s configuration parameters (step angle, current, internal ramp, functioning type, etc.) it’s possible to activate the following features: • set ratio between the reference speed and the motor speed (Gear Ratio); • set min and max full scale of the analog reference (0÷10V or – 10V÷10V); • Enabling/Disabling of the position and velocity feedback (open loop/closed loop); • Set tracking type (clock & dir, clock & dir with internal ramps, tracking of an incremental encoder, speed tracking of an analog signal). • Advantages of Closed Loop Control: Open Loop Control • compared to an open loop stepper solution; - reliable positioning without synchronism loss; - keeping stable and automatic recovery of the original position in case of positioning errors caused by external factors such as mechanic vibrations; - 100% exploitation of the motor torque; - ability to work at high speed in relation to the current control which is regulated in accordance with the load variations, where the normal open loop systems use a constant current control at all speeds without taking into account the load variations. Closed Loop Control • compared to a brushless servo-controlled solution: - no need for power regulation (automatic current regulation according to the load variations); - keeping stable of the position without fluctuations after the positioning completion; - fast positioning favoured by the independent control of the integrated DSP; - Continuous and fast execution of short stroke movements thanks to the short positioning time.
