故障现象:当按压srnm/s档和25mrn/s档时走纸速度均为srnm/s,按压50rum/s档和IO0nim/s档时走纸速度均为50rum/s,但速度显示与按压的档位相同。故障分析:该机走纸稳速电路是采用锁相环路来达到稳速的目的,速度大小的控制是改变触发脉冲的频率来实现的。上述故障肯定出
Symptom: When the srnm/s and 25mrn/s are pressed, the speed is srnm/s. When pressing 50um/s and IO0nim/s, the speed is 50mm/s, but the speed is displayed and pressed. The same gear. Failure analysis: The machine adopts a phase-locked loop to achieve steady speed, and the control of the speed is achieved by changing the frequency of the trigger pulse. The above failure is definitely out
