VIX步進電機驅動器VIX步進電機驅動器
ViX微步進驅動器
功率單元具有全PWM控制使用正弦轉換。用戶可選擇解角器或編碼器反饋。標準RS-232界面，同時現場匯流排模組提供CANopen 和 RS-485通訊。Compumotor. ViX驅動器適合在高動態、多軸套用中使用，而不需要獨立電源供給，在分散式控制中，它可作為一個獨立的驅動器/控制器使用。
VIX Series
Small, Intelligent and Powerful Digital Servo/Stepper Drives and Drive/Controllers
With its all-digital, DC-powered design, the ViX family of awardwinning
drives and drive/controllers offers a new level of
economical servo performance. Available in both drive-only
and intelligent-drive/controller platforms, the ViX family gives
users a robust and cost-effective DC product, particularly in
multi-axis applications.
Designed for easy set-up and tuning, the ViX uses wizardsbased
software that enables users to implement a fully
configured system within minutes of unpacking the unit. Its
small size–just 4.9 x 1.65 x 3.35 inches–makes it ideal for
narrow applications and for direct-panel mounting, or for
attachment to a standard DIN rail using an optional adapter.
