AUTONICS STEPPER MOTOR DRIVER PDF

The system offers direct control via network connection with master control devices such as PCs and PLCs, removing the need for separate motion controllers. The stepper motor system offers accurate and precise position control through feedback from the integrated encoder without the hassle of tuning and vibration of conventional servo motors. Zoom In Accurate position control with quick response rates The integrated encoder on the motors provide feedback of the current position in reference to the input pulse, allowing extremely accurate and precise control. The brakes are installed on the center area of the motors, providing more brake power compared to motors with brakes installed in the rear.

The Max holding torque of the motors is from 0. Two types of connection types are available. One is standard type with 10 wires, another is pentagon type with 5 wires. Autonics offers both shaft type and hollow type stepper motors. Both sides shaft type also is available as an option.

Geared type assures the maximum torque output. The full step angle for the stepper motor is 0. The drivers are available with full step type or with micro step type. That means the smallest step available in the micro step is 0. The drivers are also available in the 3 type of current ratings as mentioned above. The drivers are available with 3 types of power ratings. The drivers are available with Bipolar Constant current pentagon driver method.

The driver can be controlled by a controller or by a PLC with suitable signal to the driver at suitable time as per the programming sequence. A stepper motor system is an electro-mechanical rotary actuator that converts electrical pulses into unique shaft rotations. This rotation is directly related to the number of pulses.

Stepper motors feature bi-directional control, built-in braking, variable torque, power control, precision accuracy, high resolution, open-loop control, and direct interface to digital systems. Compared to other servo systems, steppers exhibit an excellent power to weight ratio, minimum rotor inertia, no drift, no starting surge, and no cumulative errors. When the coils are sequenced correctly, the motor rotates for- ward. When the sequence is reversed, the motor rotates in reverse. When the sequence is held, the rotor brakes in place.

Typical applications are as follows: Stepper motors are used in automotive gauges, machine tooling automated production equipment and also in retrofit kits stepper motor controllers and motors for CNC machine controls.
