Common Faults in Universal Testing Machine Operation and Solutions

In the long-term operation of the universal testing machine, a series of problems will arise due to the aging of the parts or improper maintenance . Here we will summarize some possible failures and solutions for the users who are using or are ready to purchase. Provide some help:

Failure analysis:

The host does not start Check if the power cord is connected Check that the power cord is connected correctly and securely.

Whether the three-phase 380 power supply is lack of phase Check if the power socket is missing phase, and if the power line is off.

The emergency stop button is pressed to lift the emergency stop button

The limit switch turns on the adjustment limit button so that it is off.

Whether the sensor is hit by the initial force when starting the machine, and whether the sensor has obvious deformation? If so, the sensor is bad

Zero adjustment parameters have been changed to open the zero adjustment program for hardware zero adjustment

Whether there is any welding or disconnection of solder joints

The force value beats near a certain point and there is no response. Jig slipper to select the right fixture

At the beginning of the curve, there was a section of the platform specimen that was not tightened and the load start recording value was set too small. Set the value to a larger value and filter out the platform section.

Solution:

1) The switching power supply is working properly. Measure the voltage at each output point of the switching power supply

2) The host starts but does not operate. Check whether the sensor connector is connected and whether there is a force value display. Connect the sensor connector and reconnect the sensor connector.

3) Whether the communication line between the computer and the host computer is in poor contact with the center of gravity of the communication line

4) Panasonic servo system has no error message If Error is displayed, the servo system error, restart the host

5) The force parameter is not accurate. The initialization parameter of the force sensor is called. Correctly recall the initialization parameter that is consistent with the sensor.

6) The force calibration parameter has been modified to recalibrate the force value

7) The computer displays "overload" or the force value cannot be zeroed. The sensor connector is fully connected. Reinserted sensor

8) The force parameter has been modified to recalibrate the force value.

These are commonly asked solutions. If you encounter problems that cannot be solved during the operation, you can contact us. We will arrange professional technicians to answer your questions.
