1. The control signal of the cutting machine is not input into the system
A. Check whether the oil pressure of the cutting machine system is normal, and judge the working condition of the oil pressure pump and the overflow valve.
B. Check whether the execution element is stuck.
C. Check whether the input and output electrical signals of the servo amplifier are normal and judge its working conditions.
D. Check whether the electrical signal output of the electro-hydraulic servo valve changes or the input is normal to judge whether the electro-hydraulic servo valve is normal. Servo valve failure is generally handled by the manufacturer.
2. The control signal of the cutting machine is input to the system, and the execution element is moving in a certain direction
A. Check whether the sensor is connected to the system.
B. Check whether the output signal of the sensor and the servo amplifier are misconnected into positive feedback.
C. Check the possible internal feedback fault of the cutter servo valve.
