The ASM surface mount machine suddenly slowed down during operation, half the speed before.

Handling strategies and troubleshooting steps

Please conduct a systematic investigation following the order from simple to complex and from the external to the internal.

Step 1: Quick check and reset (completed within 5 minutes)

Check the device status indicator and UI:

Carefully observe the operator interface to see if there are any yellow warning messages or prompts such as "Safety Door Open" or "Slow Down".

Check the machine status bar to see if it displays "Production - Deceleration" or a similar mode.

Perform a full restart:

Completely turn off the device power supply (including the main power switch), wait for 1-2 minutes, and allow all capacitors to discharge.

Power on again to restart. This is an effective method to clear temporary software errors.

Step 2: Systematic investigation (following the order from the external to the internal)

1. Safety and interlock inspection

Check all safety doors one by one: Along the equipment track, reopen all safety doors and covers (including the rear cover) and then firmly close them, listening for the "click" sound indicating that the lock is in place.

Check the emergency stop buttons: Inspect the entire machine and confirm that all emergency stop buttons have been fully rotated out for resetting. You can try pressing each button one by one and then resetting them to ensure proper functionality.

Clean and inspect the safety light curtain: Locate the infrared safety light curtain inside the equipment (usually on both sides of the moving area), clean its emitter and receiver lenses with a dry cloth to ensure that they are not obstructed by dust or oil. Observe whether the light curtain status indicator is working properly.

2. Inspection of the gas circuit system

Check the barometer: directly check the barometer reading on the equipment or in the workshop to confirm whether the air pressure is within the required range for the equipment (usually 6-7 Bar).

Check the air circuit: Inspect the main air pipe for any signs of bending or flattening; verify that the filter's drain valve is functioning properly, and ascertain if the automatic drainer is blocked, causing a decrease in air pressure.

3. Software and settings inspection

Check the operation mode:

In the operating software, look for options named "Production Mode", "Speed Setting", or "Tortoise/Hare Mode".

Ensure that the device is in "Maximum Speed" or "High Speed" mode, rather than "Debugging", "Slow Speed", or "Optimization" mode.

View alarm/event log:

Access the alarm history or event log of the machine.

Focus on all warning messages before and after the time point when the problem occurred, not just error messages. An inconspicuous warning may be the reason for the speed limit.

4. In-depth hardware diagnosis

Check the status of the servo driver:

Open the electrical cabinet door of the servo drive (Note: It must be operated by a professional engineer after powering off to ensure safety!).

Observe the status indicator lights on all servo drives. Under normal circumstances, they are usually green and constantly on or flashing. If there are yellow or red indicator lights, note down their codes and refer to the manual.

Check motor temperature: After the equipment has been running for a period of time, check whether the temperature of each axis motor has increased abnormally through the drive monitoring software, or feel whether the motor housing is hot to the touch under safe conditions.

Perform I/O status check:

In the device maintenance mode, locate the I/O status monitoring page.

Check all safety-related input signals (such as sensors of each safety door, emergency stop buttons, and light curtain signals) one by one to confirm that their status is consistent with the physical reality (door closed = 1, door open = 0). If a sensor still displays an "open" status when the door is closed tightly, it is likely that the sensor has been damaged.

Step 3: Seek professional support

If all the above steps fail to solve the problem, it is likely that there is a deeper hardware or software fault.

Contact ASM technical support: Inform the technical support engineer in detail about the troubleshooting steps you have taken and the phenomena you have observed.

Provide key information:

Specific equipment model (such as SIPLACE X4i).

Device serial number.

Control system and software version.

The complete alarm log file.

The specific time and frequency of the occurrence of the problem.
