Rotation becomes decoding chip and is connected with digital signal processor, receives and reconciles corresponding signals of rotating transformer, will
It is sent to data signal manager and host computer, and wherein rotary transformer is turn of the rotating object driven for measurement motor
Axis angular displacement and angular speed.
Digital signal processor receives the control instruction of the speed from host computer by serial communication modular, receives simultaneously
Rotation becomes the feedback speed signal of decoding chip output, and rate control instruction and feedback speed signal are in digital signal processor
After comprehensive calculation process, export PWM speed governing and DIR motor drive direction control signals, by line driving buffer module export to
Motor driver carries out power amplification, and motor rotates, until motor reaches set rotating speed.
Current sensor is connected by ADC conversion chips with digital signal processor, and the power for gathering motor supplies
The output current information of power supply, the current analog signal of generation change into data signal by ADC conversion chips and are conveyed to number
Word signal processor, and then motor power supply is monitored in real time.
Power module is arranged to avoid the interference that control of the power of motor power supply to servo-driver is powered, and is driven for servo
Dynamic device provides isolation and linear power supply, power power supply is physically separated with control power supply.
