Replacement & Compatibility FAQ
Q: Can the ATV320U22N4B directly replace the ATV312HU22N4?
A: Yes, the ATV320 is the recommended next-generation replacement. Power and voltage ratings are identical; however, terminal layout and parameter mapping differ — refer to Schneider’s migration guide (document NVE41289).
Q: Is the ATV312HU22N4 compatible with single-phase input?
A: No. The N4 suffix denotes 3-phase 380–500 V input only. For single-phase 220 V, select the ATV312HU22M2.
Q: Can I use a third-party VFD as a drop-in replacement?
A: Electrically possible if ratings match, but control wiring, parameter settings, and communication protocols must be reconfigured. Konmask recommends original parts for critical applications.
Q: What is the warranty on this product?
A: Konmask provides a 12-month warranty against manufacturing defects. Schneider Electric’s standard warranty terms apply for factory-sealed units.
Q: Do you provide installation support?
A: Yes. Our technical team can assist with wiring diagrams, parameter setup, and SoMove configuration files. Contact us via email or WhatsApp.
