Our Team Expertly Repairs Yaskawa AC Servo Drive SGDV Sigma V series
Precision Zone specializes in Yaskawa product repairs servicing a wide range of AC Servo series such as Yaskawa SGDV Series Servopack.
Yaskawa AC Servo Drive SGDV has been developed for the most advanced Factory Automation and Factory Machining Systems, including robots and machine tools. Sigma one, two and three are all able to be upgraded to the Sigma five platforms. Controllable with a digital operator or SigmaWin Plus.
When assessing the functionality of a drive, our repair team conducts a four-step evaluation:
- 1. Visual Overview
- 2. Static Test
- 3. Checks Under Power
- 4. Alarm Codes Verification
This overview is Precision Zone’s basic troubleshooting process. Once our repair team starts on the job we use specialized, customized test fixtures, Huntron tracker, signal generator, oscilloscope, milli and mega ohm meters and other necessary tools to assure quality repair. Most importantly, every repair is fully tested in custom-built simulators under load to replicate real-life working environment.
Precision Zone goes as far as using heat chamber and overnight dynamic testing to guarantee performance of the repaired product when it comes back to the customer.
Repair Process for SGVD Series Servopacks
Visual Overview
When conducting a visual check, the technician inspects the drive for any mechanical damage to the drive and print circuit boards. Then the team proceeds to verify connections are tight and correct inside the drive and there are no loose screws, wires or particles. Additionally, we look for any burn marks anywhere on the components or chassis. During the visual inspection technical team notes excessive dirt on cooling components and records clogged heatsink.
Static Test Basic
Precision Zone repair technicians use digital multimeter with diode testing capabilities and resistance measurement to conduct a static test. In the instance of Diode testing, our team is looking to check input and output modules.
Input Module Testing
Positive Lead | Negative Lead | Reading |
---|---|---|
L1 | Positive Bus Terminal | ~ 0.48V |
L2 | Positive Bus Terminal | ~ 0.48V |
L3 | Positive Bus Terminal | ~ 0.48V |
Negative Bus Terminal | L1 | 0.48V |
Negative Bus Terminal | L2 | 0.48V |
Negative Bus Terminal | L3 | 0.48V |
Output Module Testing
Positive Lead | Negative Lead | Reading |
---|---|---|
U | Positive Bus Terminal | ~ 0.43V |
V | Positive Bus Terminal | ~ 0.43V |
W | Positive Bus Terminal | ~ 0.43V |
Negative Bus Terminal | U | 0.44V |
Negative Bus Terminal | V | 0.44V |
Negative Bus Terminal | W | 0.44V |
We verify capacitor value using capacitor meter and examine functionality of circuit breakers and contactors in the drive.
The last step in a static test process is checking the Regen Resistor. Resistance output results will vary depending on the size of the drive, but should not be shorted.
