The VW3AE0655 is a sinus filter from the Altivar 61 Plus range, designed as a protection accessory for Altivar floor-standing enclosures with separate air flows or the compact version. It cleans the drive output waveform to reduce motor stress and bearing currents on longer cable runs.
What it does in the drive system
A sinus filter sits between the drive and the motor, converting the PWM output into a near-sine wave. That cuts motor heating, reduces acoustic noise, and lets you run longer unshielded cable distances without reflected-wave damage. On an Altivar 61 Plus cabinet drive, this filter bolts into the floor-standing enclosure with separate air-flow routing — not a retrofit for a standard IP20 panel.
