VIX步进电机驱动器

ViX微步进驱动器

功率单元具有全PWM控制使用正弦转换。用户可选择解角器或编码器反馈。标准RS-232界面，同时现场总线模块提供CANopen 和 RS-485通讯。Compumotor. ViX驱动器适合在高动态、多轴应用中使用，而不需要独立电源供给，在分布式控制中，它可作为一个独立的驱动器/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.
