How to Solve the Displacement Problem of Servo Hydraulic Press?

How to solve the displacement problem of the servo hydraulic press? The abnormality of the servo hydraulic press is generally reflected in the following three aspects: sensor, amplifier unit and system setting failure.

How to Solve the Displacement Problem of Servo Hydraulic Press?

1. Check the system settings of the servo hydraulic press.

If the display screen in the workstation shows that the stroke of the actuator is different from which under normal conditions, there is maybe a problem with the settings, and the system needs to be reset.

2. Check the servo hydraulic press sensor. 

If the sensor signal is normal, disconnect the feedback signal of the sensor, after repeating several times, the feedback data of the sensor is measured as a linear change line, and the sensor is judged.

3. Check the servo hydraulic press amplifier unit. 

After eliminating the fault of the sensor, it is now necessary to check whether the amplifier unit is normal. First, disconnect the output signal of the amplifier unit system. Remove the output wiring, add a DC input signal to the amplifier unit through the workstation, and then measure the amplifier, after several repetitions, the output signal of the amplifier unit changes linearly to determine whether the amplifier unit is normal.
