Torque measurement possibly invalid

Torque measurement may be invalid

The programming is incorrect as no movement is possible in the second stage.

The program has an error because no movement can be made in the second stage.

Check the programming for the Pset. Ensure that there is some movement in the second stage.

Check the programming of Pset. Ensure that there is some progress in the second phase.

Atlas tightening controller alarm E003 fault explanation

Atlas tightening controller displays E003 alarm code, usually indicating "motor overload". This means that the controller detects that the motor current exceeds the preset safe value, which may cause damage to the motor or controller, triggering the protection mechanism, stopping operation, and displaying an alarm.

2、 Atlas tightening controller alarm E003: troubleshooting

When an E003 alarm occurs, the following steps can be followed for troubleshooting:

1. Check the power supply voltage: Use a multimeter to measure the input voltage of the controller, ensuring that it is within the rated voltage range (e.g. 220V ± 10%). Excessive or insufficient voltage can cause motor overload.

2. Check motor connection: Disconnect the power supply and check if the connection wire between the motor and the controller is loose, damaged, or has poor contact.

3. Check mechanical load: manually rotate the motor shaft and check for any abnormal conditions such as jamming or excessive resistance. Excessive mechanical load can cause motor overload.

4. Check the motor itself: disconnect the motor from the load, run the motor without load, and observe if the E003 alarm still occurs. If the no-load operation is normal, the problem may lie in the mechanical load; If the alarm still sounds during no-load operation, there may be a fault in the motor itself, such as winding short circuit, bearing damage, etc.

5. Check controller parameter settings: Check whether the parameters related to the motor in the controller are set correctly, such as the rated current, acceleration time, deceleration time, etc. of the motor. Incorrect parameter settings can cause motor overload.

3、 Atlas Tightening Controller Alarm E003: Solution

Based on the investigation results, take corresponding solutions:

1. Abnormal power supply voltage: Adjust the power supply voltage to the rated range or use a regulated power supply.

2. Abnormal motor connection: Reconnect or replace the motor connection wire to ensure a secure and reliable connection.

3. Mechanical load abnormality: Check the mechanical transmission part and eliminate faults such as jamming and excessive resistance.

4. Motor malfunction: Replace or repair the motor.

5. Controller parameter setting error: Reset the controller parameters based on the motor nameplate parameters.
