Overspeed
– programmable speed switch
In heavy duty applications, like in steel industry or in cranes, it is common that an incremental encoder signal needs to be complemented with a separate relay output for overspeed indication. This is typically used to prevent falling loads, or to protect motors and machines from breakdowns. Thereby, standstills and costly production losses can be avoided.
The critical speed limits vary with the exact motor types and applications. In the same plant there may therefore be a need of different speed limit configurations on different drives. This is one of the reasons why Overspeed, the integrated programmable speed switch solution from Leine Linde, is so appreciated!
Flexible speed range 0-6000 rpm
Overspeed is a programmable speed detection system, and features four different relay switches for immediate speed control. In an enclosed easy-to-use software, you will set your own values for overspeed, underspeed, standstill, or direction.
Leine Linde’s solution provides great flexibility as the speed range covers 0-6000 rpm. The same unit may be used for different installations, programmable with the settings needed for every specific use.
Overspeed can be integrated in an encoder from the 800 series or the 1000 series as an option. It can also be acquired as a separate unit, Overspeed module. Programming is made over USB with help of an included PC software.
超速
– 可编程速度开关
在如炼钢厂或起重机之类的重工况应用中，增量编码器信号通常需要通过单独继电器输出辅助才能进行超速控制。这通常用于防止下降负重或避免发动机和机器的故障。因此，就可以避免停机现象和严重的生产损失。
临界速度限制会随着具体的电机种类和应用的变化而变化。因此，在同一工厂中，不同的驱动可能会需要不同的速度限制配置。这也是 Leine Linde 的集成可编程速度开关解决方案得到了众多客户赞赏的原因。
弹性的速度范围 0-6000 rpm
超速是一种可编程速度探测系统，配备四种不同的即时速度控制的继电器开关。在封闭式简易软件中，您可以为超速、低速、停滞或方向设置所需的值。
Leine Linde 的解决方案会提供十分灵活的速度范围（0-6000 rpm）。相同的产品能用于不同的安装和各种用途所需的可编程设置。
超速开关可作为可选功能集成在 800 系列或 1000 系列编码器上。它也可以作为一个单独的产品， Overspeed Module。借助计算机软件通过 USB 接口即可完成编程。.
