The VW3A9926 is an EMC plate kit from the Altivar Machine ATV320 accessory range, specifically designed as a mounting plate for variable speed drive size 6. It's the metal plate that closes the drive's EMC shield termination — without it, the cable gland plate leaves a gap that radiates common-mode noise back into the cabinet. This isn't a functional drive component you spec for performance; it's the compliance piece that keeps conducted emissions inside the enclosure boundary during CE marking.
Lifecycle stage is mature; product status is active.
What the EMC plate does in the cabinet
The plate mounts onto the drive chassis, covering the cable entry area where the EMC clamp bracket sits. It provides a low-impedance bond between cable shields and the drive's backplane earth.
