STEPPER GEARMOTOR DRIVER MM003AT/21-22 The step-motor is a synchronous electric motor with pulsed direct current and brushless electronic control which can divide its rotation into a large number of steps. Unlike brush DC motors, the position of the motor can be accurately controlled without an encoder (feedback). It is extremely important to choose the correct size and type of motor to suit the application. The use of a step-motor requires a careful preliminary analysis of the operating conditions in order to correctly characterise the system. Since control electronics are required to ensure an optimal use of step motors, Micro Motors has developed a dedicated driver for its product range, which offers the possibility of using the motors in a simple and versatile way. TECHNICAL FEATURES: Power supply: from 12 to 30Vdc - from 12 to 24Vac Setting current: 160mA or 330mA Operating mode: as a step-motor (STEP/DIR) or as a brush motor simulation Dimensions: 33 x 33 x 14 mm Weight: approx. 10g OVERVIEW: A = Power input terminal B = Control signal input terminal C = Speed/acceleration trimmer D = Motor connection E = DIP switch program configuration F = Service button CONNECTIONS: 1-2 = Power input +/-, for more details see “programs” section 3 = Step pulse input (5-30V, ref. program 3) 4 = Input for CW/CCW rotation (connect to GND to change the rotation direction, ref. Programs 3,4,5 and 6) 5 = Speed control by voltage input (1-5V or 2-10V program ref. 4 and 5) 6 = Speed control by current input (4-20mA ref. Program 6) 7 = GND reference point of the signals described above Viale Piave, 80/82 - 23878 VERDERIO (LC) ITALY Tel. 039.510611-499 - email: [email protected] www.micromotors.e

PROGRAM SELECTION (DIP switch “E”) BRUSH MOTOR SIMULATION WITH AC/DC DRIVER INPUT WITH SPEED (5V) AND ACCELERATION/DECELERATION CONTROL DIP switch: 1 = OFF 2 = OFF 3 = ON 4 = (see program 7) In this configuration the motor acts like a brush motor whose speed is determined by the voltage supplied on terminal 5 (from 1 to 5V), while terminal 4 determines the CW/CCW rotation (connect or disconnect to GND to reverse direction). The drive can be powered either in AC or DC mode (terminals 1 and 2). Trimmer “C” sets the acceleration and deceleration. BRUSH MOTOR SIMULATION WITH AC/DC DRIVER INPUT WITH...
