词条 | VIX步进电机驱动器 |
释义 | ViX驱动器是COMPUMOTOR公司推出的,其合并一个灵活的控制器和250/500 W输出平台在一个极紧凑的4.9 x 1.65 x 3.35-in腔体中。利用全数字化技术提供高达8A RMS持续电流输出,该驱动器的分辨率可选择范围广(200~51200steps/rev),并可在低电压(24~80V)下运行。 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.
