General Drives Questions Frequently Asked Questions
| Question | What drive power cable do you recommend and why? |
| Answer | Beldon 29500 – 29507 cables are specifically designed for use with VFDs. Using the wrong cable can increase the detrimental effects from ringing due to capacitive coupling. Thermoplastic insulation like in standard THHN cable will break down over time with connectivity from inverters to motors. The standing waves caused by PWM will cause high voltage potential on single conductors. This renders corona (reflective/ringing voltage) in the air gaps between the conductors, which could breakdown and cause a system failure. |
