FAQ

What drives is the VW3 A7 701 compatible with?

It is designed for various Schneider Electric Altivar drives, including the Altivar 31, 312, 32, and the modern Altivar Machine ATV320 series. Always check the drive’s manual for specific power and resistance requirements.

How do I ensure proper cooling for this resistor?

This unit is designed for natural convection cooling. It must be installed in a vertical position with sufficient clearance around it as specified in the installation manual to allow for proper airflow and heat dissipation. Do not enclose it in a small, unventilated space.

Can I connect multiple VW3 A7 701 resistors in parallel to handle more power?

No, connecting braking resistors in parallel is generally not recommended without explicit manufacturer approval. It can lead to uneven current distribution and potential overheating. If more braking power is needed, you should select a single resistor with the appropriate higher power and lower resistance rating as specified by the drive manufacturer.
