PLC control step motor problem
The first step is that you should have a pulse of 3200 pulses. The domestic stepper motor can also go up to 600, without any doubt about stepping motor performance! The frequency of 8000HZ, I think you should check your pulse output if you have a question, do you use the high speed pulse output module? And then you have a separate PLC control motor or a connection with other devices! PLC model?
So if you try, 1/16, 8000HZ try it out! What about the effect? It should be 150 revolutions per second; And then you know, if you go to 14, 8000HZ, you know what's the problem with the pulse here or the problem with the motor here! What I'm talking about is not the location problem, the PLC's high speed pulse output is not as accurate as it says, and the balance is normal!
Step motor if it is from the Angle of the building Lord 1.8 ° segmentation is 1/16 3200 pulses for 1 round. If your frequency is 8khz is 8000/3,200 = 2.5 (revolutions per second) The speed is 2.5 r/s times 60 equals 150 revolutions per minute What is the maximum response frequency for the step driver of the building? If the maximum can reach 200 KHZ So that means 200,000 over 3,200 is 62.5 r/s 62.5 r/s/s = 3750 revolutions per minute (highest) The problem may be: the motor response frequency is not enough The step drive response frequency is not sufficient The voltage of the step drive and the electrical failure of the motor cause the drive current to be small, which cannot be driven or dropped. It can only be solved by elimination method.
