Our Team Expertly Repairs Magnetek AC Inverter GPD505/506 Series
Precision Zone specializes in Magnetek product repairs servicing a wide range of AC inverters such as Magnetek GPD505/506 Series inverter.
The GPD505/506 drive is a full featured drive providing outstanding quality, performance, and flexibility through 300kW. This drive combines easy to use network communications, feedback, and expandable I/O to control anything. The GPD505/506 was designed by Magnetek to operate cranes and other forms of material handling.
When assessing the functionality of a drive, our engineering team typically conducts a four-step check:
- Visual Overview Check
- Static Test
- Checks Under Power
- 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 GPD505/506 SERIES INVERTER
Visual Overview Check
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.
Using your digital multimeter check the DC buss and make sure the DC buss has been discharged.
Input Modules Testing
| Multimeter Positive Lead | Negative Side of the DC Bus |
| Multimeter Negative Lead | L1 L2 L3 |
| Diode Check | Approximately 0.2-1.0 V for each phase |
| Multimeter Positive Lead | L1 L2 L3 |
| Multimeter Negative Lead | Positive Side of the DC Buss |
| Diode Check | Approximately 0.2-1.0 V for each phase |
Output Modules Testing
| Multimeter Positive Lead | U V W |
| Multimeter Negative Lead | Positive Side of the DC Buss |
| Diode Check | Approximately 0.2-1.0 V for each phase |
| Multimeter Positive Lead | Negative Side of the DC Buss |
| Multimeter Negative Lead | U V W |
| Diode Check | Approximately 0.2-1.0 V for each phase |
We verify capacitor value using capacitor meter and examine functionality of circuit breakers and contactors in the drive.
Alarm Codes Troubleshooting
The alarms on the drive are displayed through digital operator located on the front of the inverter. The codes displayed are:
| Alarm Code | Code Type |
|---|---|
| Gf | Ground Fault |
| Oc | Overcurrent |
| ol1 and ol2 | Overload |
| RR | Braking Transistor Shorted |
| ERR | Control Board Hardware Failure |
| UV | Undervoltage |
| OV | Overvoltage |
| OH and OH2 | Overheat |
| OS | Overspeed Detection |
| OPE | Parameter Alarms |
| PF and PH | Phase Loss or Open Phases |
The majority of these alarms can be triggered if there is a fault in the control circuit.
