The new 400 v offering includes a completely new amplifier design that offers advantages to machine builders and end users seeking to upgrade a 400 v motion control system. The amplifier has a new book-style form factor built around a single standard height and two standard widths. This makes control cabinet design and configuration easier and more predictable. Installation ease is also enhanced by the presence of wiring connections on the top and bottom of the amplifiers, allowing the routing of wiring above and below the amplifier and eliminating the need for terminal board breakouts.

The new 400 volt line retains the full set of performance advantages shared by all Sigma-7 products:

• 3.1 kHz frequency response, which sets a new industry standard for bandwidth and servo performance

• 24-bit encoder feedback for unequaled resolution and precision positioning

• New tuning functions that combat vibration, resonances, friction and ripple effects

• Motor compatibility with comparably sized past Yaskawa products, for easy upgrading
