The customer’s setup was unique in that there were two motor armatures in series with their respective fields in parallel. Our team cleaned and tested each thyristor assembly to ensure they were working within factory operating specifications. Two of the thyristor assemblies were degraded and required rebuilding.
We then replaced the existing 6RA24 command module and field supply with a new Siemens 6RA80 command module. Because all the existing wiring from the new command module to the thyristor assemblies was an exact match, we were able to complete the conversion in four days. With the new drive integrated into the customer’s system, they now enjoy a more constant speed from their kiln, which improved their quality control measures. The new drive is also more reliable, which improved the customer’s production rates.
The Quad Plus team was also able to integrate the new drive into the customer’s existing IP/Ethernet network, which allows monitoring and control of the drive from their existing PLC network. By monitoring data such as amps, volts, and torque, simple troubleshooting can occur from a laptop at the engineer’s desk or control room rather than requiring an employee to physically look at the drive.
