Does the step motor drive use DSP chip?
DSP chip main features: (1) a multiplication and an addition in a single instruction cycle; (2) the program is separated from the data space and can access both the command and the data at the same time. (3) there is fast RAM within the slice, usually accessible through two separate data buses; (4) hardware support with low overhead or no overhead cycles and jumps; (5) quick interrupt processing and hardware I/O support; (6) a number of hardware address generators that operate within a single cycle; (7) multiple operations can be performed in parallel;
As the world cries for efficiency, energy efficiency and low noise, the DSP is expanding into the entire motor market, controlled by high-end industrial motors. The ASD878R, developed by handebao, is based on the DSP control chip, combined with the unique control circuit. It is a new generation intelligent digital step motor drive, user can set 1-128 segmentation. Low medium high speed running is very smooth, almost no vibration and noise, completely solve the defect of step motor low speed vibration and noise. Internal parameters are integrated with automatic parameters, which can automatically generate optimal running parameters for different motors. Precise current technology control technology, which reduces the temperature of the electric motor, automatically halve the dynamic current at rest, and the performance of the step motor is maximising. ASD878R two-phase stepper motor drive stepper motor control using DSP is a high level of integration, the generality of the new motor control DSP to system level chip development, integrates the analog-to-digital conversion of analog circuit, PWM motor control module, flash memory and peripherals, such as components, thereby reducing the number of elements and the whole machine system board size, reduce the overall cost of the system.
Supports assembly line operation to enable the operation of reference, decoding and execution to overlap. DSP chip advantage: Simplify the design of the entire motor control system; Low cost and market advantage; The ability to respond quickly and efficiently in the accuracy of motion control; In the chip control algorithm, the algorithm can improve the arithmetic precision. The digital revolution is promoting the extensive application of high performance DSP, han debao ASD878R two-phase stepper motor drive research and development is a result of market mechanism, and the user to select the best basis for economical and efficient drives.
