1391-DES45 微处理器的数字伺服驱动器

概述：

1391-DES45-DI-AQB是一种基于微处理器的数字伺服驱动器，主要用于Allen-Bradley的1326伺服电机。该伺服驱动器设计紧凑，但该驱动器支持附加组件，这是驱动器可扩展性功能的一部分。

1391-DES45-DI-AQB的主要特点包括一个集成显示器，用于伺服驱动器参数的本地配置。它也有一个编码器输出可选的选择，包括2048,1024,512和256脉冲每电机旋转。更高的脉冲提供更高的分辨率和更高的反馈精度。

这个伺服驱动器的前面板显示人机界面模块(HIM)与五(5)个数字键盘，允许导航和修改驱动器的参数。它还具有一个整体状态LED，当没有检测到故障和低总线电压时闪烁绿色;无故障且母线电压正常时绿色常亮;当驱动器发生故障时，闪烁红色。它还有一个使能LED，当使能输入关闭时，它是稳定的绿色。当使能输入打开时，使能LED不亮。

TB2和TB3接口端子位于伺服驱动器的底部。TB2用于对接外部信号，TB3用于终止编码器输出信号。集成熔断器和断路器以及TB4, TB5和占空比选择开关位于驱动器顶部。虽然这个驱动器有内部保护电路，但建议安装外部保护。如果使用隔离变压器，Allen-Bradley建议使用合适的1391隔离变压器，因为使用第三方变压器将使设备的UL列表无效。

1391-DES45 微处理器的数字伺服驱动器

The 1391-DES45-DI-AQB is a microprocessor-based digital servo drive primarily used in Allen-Bradley's 1326 servo motor. The servo drive is compact in design, but the drive supports add-ons, which are part of the drive's extensibility capabilities.

The main features of the 1391-DES45-DI-AQB include an integrated display for local configuration of servo drive parameters. It also has an encoder output of optional options, including 2048,1024,512 and 256 pulses per motor rotation. Higher pulses provide higher resolution and higher feedback accuracy.

The front panel of this servo drive displays the Human Machine interface module (HIM) with five (5) numeric keypads that allow navigation and modification of the drive's parameters. It also has a global status LED that flashes green when no fault and low bus voltage are detected; Steady green when there is no fault and the bus voltage is normal; Blinking red when the drive fails. It also has an enable LED, which is steady green when the enable input is turned off. The enable LED does not light up when the enable input is turned on.

The TB2 and TB3 interface terminals are located at the bottom of the servo driver. TB2 is used to interface with external signals, and TB3 is used to terminate the encoder output signal. Integrated fuses and circuit breakers as well as TB4, TB5 and duty cycle selector switches are located on top of the driver. Although this drive has an internal protection circuit, it is recommended to install external protection. If using an isolation transformer, Allen-Bradley recommends using an appropriate 1391 isolation transformer, as using a third-party transformer will invalidate the UL listing of the device.
