Songwei long to do the repair and replacement of
Mitsubishi CNC parts, have seen too many "early symptoms did not pay attention to, and finally the whole machine on the ground,” the example. Today we will talk to you,
Mitsubishi servo drive problems usually have what signs, early discovery, early repair, save heart and money.
1. Motor or Drive Began to "Sound”
Equipment running suddenly a little strange sound? Like "buzzing”, ‘rattling’, "clicking”? That's not background music, it's usually a problem.
Common possibilities include:
* Worn bearings.
* Internal false connections or electrical interference.
* Motor shafts are not concentric, jamming.
Suggestion: turn off the machine first and open it up to see if there are any loose or obvious abnormalities. If it still rattles, it's best to get professional equipment to measure it. We Songwei all repaired drives will do quiet test before shipment to ensure that the factory state is stable.
2. Motor Action Is Not Right, Positioning Inaccuracy, Jitter, Offset
Machine began to appear "the stop is not stopping”, "move more”, "off position” phenomenon? A high probability that the servo drive in the "temper tantrum”.
Common culprits are:
* Encoder feedback abnormal.
* Parameter drift or set the wrong.
* Interference is too strong, the signal is contaminated.
Songwei has a test program specifically designed for "abnormal motion faults”, which can locate the problem very quickly.
3. Alarm Codes Become More, Often Pop-Up Window?
Mitsubishi drives began to frequent alarms, such as AL.12 (overcurrent) or AL.37 (encoder abnormality)? These codes are not "just for fun”, they are the device asking for help.
Possible causes of these alarms include:
* Deteriorating internal parts.
* Too much load on the shaft.
* Loss of feedback signal or unstable communication.
What to do: Don't rush to press off the alarm, take a photo/screenshot to save the alarm. Send it to our technical team at Songwei, we are "reading the alarm code” every day, and will soon be able to help you analyze the cause.
4. Unusually High Temperature or Burning Smell?
Is the drive hot and scary? Even start to smell a little "plastic paste”? This time please stop immediately, or burn out is a small matter, serious safety risks.
Possible reasons are:
* Heat dissipation mouth blocked, bad fan.
* Capacitor aging, serious heat.
* Overload operation, over-current, over-voltage work.
Suggestion: Clean the dust in the control cabinet regularly, especially the air vent. We, Songwei, will replace all temperature sensitive components and do high temperature aging test when repairing the drive.
5. Voltage and Current Jumps Around and Is Unstable
This condition is not easy to detect, but it is the "culprit” behind the fluctuating performance of the equipment.
Possible component problems include:
* IGBT module damage.
* High power supply fluctuations.
* Problems with current/voltage sensors.
The best way: have a multimeter or oscilloscope on the first test; not, you can also send the device directly to Songwei to do a full load test, we can measure the current waveform, drive the output state, the problem at a glance.
What to Do When These Problems Occur?
Don't delay, don't gamble. Stop when you find a problem, don't wait for the machine to go on a complete strike and then regret it. You can handle it like this:
1. Stop the machine immediately to ensure safety.
2. Record the alarms and operating phenomena.
3. Contact a professional maintenance organization (e.g. Songwei).
4. Switch over to spare parts, if available, to avoid a long production stoppage.
Songwei provides free consulting services and can assist you remotely in determining the fault; if you confirm that you need to replace the parts, we can also provide original or compatible parts, and we can also help you to do a complete set of drive testing and repair.
Why Do People Look to Songwei to Repair Mitsubishi Drives?
Our advantage is not just to sell parts, but to understand the machine and also the field situation:
* Mitsubishi original, new and old parts are in stock, fast delivery.
* All tested before shipment, rest assured that the installation.
* Repair with warranty, repaired not afraid to use.
* Global shipping support, fast response, stable service.
* Experienced technical engineers, not just "read the manual” kind of thing.
From equipment diagnosis to maintenance and testing, we are one step, so that you can save heart and effort.
Final Summary
Servo drive will not be bad for no reason, before the problem will certainly give you a signal. Unusual sounds, alarms, heat, positioning inaccuracy ...... these are it reminds you: "I can't hold out any longer”.
It's so much better to find it and fix it early than to wait until it breaks down completely.
