What Does a Servo Drive Do, and How Does It Work?
A servo system can be comprised of a number of integrated components, with the two most prominent being the servo drive and the servo motor. In essence, the servo drive serves to translate incoming command signals into the right voltage and current needed to power the servo motor, which then produces the force needed to get your equipment moving. A problem with either your servo driver or your servo motor will result in less-than-optimal performance issues for your system.
A servo drive is sometimes referred to as an amplifier. It could also be considered as the nervous system connecting the controller with the servo motor. The drive receives command signals for position, speed, or torque requirements, and then adjusts the voltage and/or current are needed to engage the servo motor properly in order to achieve the desired outcome. For industrial, research, and government applications, servo drives are utilized for automation and robotics, machining, laboratory functions, aerospace, defense, communications, offshore & underwater operations, and much more. Without a properly functioning servo drive, your servo motor could be rendered practically useless. If your servo system is underperforming, the issue may not be with your motor; the problem could live with your servo drive. The AES team can help get your servo drive – and your servo system – back online!
What Can Lead to Servo Drive Failure?
Servo systems are generally very efficient and reliable. Even so, because this closed-loop system includes a motor, drive, controller, and feedback device, a problem with any one of these components can throw a wrench into the whole system. Here are common issues we see with servo drives at AES:
Oscilloscope reads as all noise
In many cases, this simply means that the current monitoring output hasn’t been properly isolated from the AC power supply or transformer.
Servo motor runs faster in one direction
There could be a few reasons why the motor runs faster in one direction than in the other. There could be a phase error with the servo motor itself. The deviation potentiometer could also be in the wrong position. Another potential cause could be that the test/deviation switch is toggled to the wrong setting.
Servo motor stalls or sputters
Sometimes there could be a polarity error with your speed feedback. There are different approaches for addressing this, depending upon the design of your particular unit. In other cases, the encoder power could be lost due to encoder power feedback. If this is the case, a power supply check is in order.
LEDs are green, but the servo motor isn’t moving
Assuming there isn’t an issue with the motor itself, this usually points to the need to do some troubleshooting with the INHIBIT ports. It’s also possible that the command signal isn’t properly connected to the servo drive signal.
Internal short circuits or circuit board issues
Any industrial electronic equipment which depends upon printed circuit boards (PCBs) can eventually fail, and that includes servo drives and amplifiers. Needed PCB service may require replacement of resistors, capacitors, and diodes, along with gold finger contact and trace repair services.
Servo Drive Repair with AES
Sometimes servo drive repair means focusing on the stand-alone drive itself. In other cases, it may mean troubleshooting and servicing the entire controller-drive-motor-feedback servo system. No matter what’s going on with your servo drive or servo system, AES has you covered. Servo repair is really one of our specialties!
Send Your Servo Drive to AES
Pack your servo drive (or integrated servo system) with foam, bubble wrap, or appropriate protective material, and just send it on to AES! If you can describe any specific issues you’ve been facing with your drive, that will also be helpful. But if all you know is that your servo drive isn’t working properly, that’s fine. Just send it on in! Our team can effectively troubleshoot, diagnose, and deliver whatever repair solution may be needed.

Equipment Check-in, Troubleshooting, & Repair Quote
Once we receive your servo drive, we’ll assign it a unique tracking ID as part of our check-in procedure. We’ll then move right to troubleshooting and diagnosis, where we’ll break everything down and assess each individual component. We’ll then provide a detailed repair quote describing exactly what will be needed in order to get your drive back up and running properly.
Your individually-assigned Customer Service Representative will connect with you personally; at AES, we happen to believe the individual, personal touch is best. We’ll let you know what we discover after analyzing your servo drive, including our recommended repair and service prescriptions.
