This paper studies a DC double closed loop digital PWM speed adjusting system controlled by 8098 single chip computer to explore the feasibility for the middle or small power motors.
The computer control system hardware based on S7400 PLC, the system power supply, full digital 6RA70 DC drive configuration for the system and PROFIBUSDP field bus configuration are introduced.
