Servo motor with the advance of science and technology, the early servo motor simulation system can not completely meet the requirements of motion control, in recent years, following the microprocessor, the use of new type digital signal processor, a digital control system, the control part can be completely by the software, such as: panasonic servo motor A4 and A5, satisfy the operating machinery, processing machinery, printing machine, high speed winding machine and so on the different needs of, so, what is the difference between A4 and A5 panasonic servo motor? See below in detail. What is the difference between A4 and A5 panasonic servo motor in detail is as follows: a, panasonic servo motor A4 and A5 in common. 【1 】Use simple: miniaturization of planning. 【2 】Using the lunch: add motor types, used to more occasions. 【3 】Using fast: using high speed high echo. 【4 】Using intelligent, simple operation and high performance. 【5 】Use that correspond to the ROHS directive, choose out lead solder, environmental non-toxic. Second, panasonic servo motor A4 and A5 differences. 【1 】Echo frequency different: A4 is 1 KHZ, A5 is 2 KHZ; 【2 】Different pulse frequency: A4 is 2 m to 4 m, A5; 【3 】Resolution had the very big enhancement: A4 models have 130000 pulse, A5 model can reach 1. 04 million pulses. 【4 】Encoder connection number is different: A4 series have simplified pulse type drive, panasonic servo motor interface flange remains the same as a whole, the length is shorter, smaller drives, and other basic are exactly the same.
