Common Issues with VARIABLE FREQUENCY DRIVES
| PROBLEM | CAUSE | SOLUTION |
| Electromagnetic Interference (EMI) | VFDs inherently generate more EMI that gets radiated into the environment. The EMI emitted from the power cable can induce voltages, currents, or crosstalk onto adjacent cables, which is potentially dangerous to surrounding equipment. |
ServiceDRIVE® uses a 5-mil copper tape shield with 50% overlap to ensure full containment, reducing EMI emissions from the cable. |
| Premature Cable Failure | Thermoplastic insulation, like THHN, cannot withstand the voltage spikes associated with VFDs, resulting in hotspots and pinholes in the insulation and arcing across wires. | ServiceDRIVE® uses NFPA 79 compliant thermoset (XLPE) insulation, which better resists the elevated temperatures generated when voltage stresses are high. |
| Stray Currents | Common-mode stray currents occur when current is unintentionally induced into the grounding system or other unintended conductors instead of being contained inside the cable and off the ground path. This can cause unwanted issues with control systems and mechanical parts, significantly affecting reliability and performance. |
The complete ServiceDRIVE® System provides the best low impedance path and addresses the effect of common-mode stray current to the drive, motors, and electronic equipment within proximity of the drive system. |
| Motor Bearing Failure | Stray currents traveling through the motor create pits and fluting in the motor bearing raceway. Once this starts, it is self-perpetuating, substantially shortening the lifespan of the motor and ultimately resulting in premature motor failure. | Because the stray currents in the grounding system are reduced, ServiceDRIVE® minimizes bearing failure due to common-mode stray current and intermittent trips or damage to sensitive electronic equipment. |
