控制单元执行变频器的闭环控制功能。除了闭环控制功能外，还具有其他功能，可通过参数设置用于具体应用。控制单元分为不同型号：

• CU240D DP
• CU240D DP-F
• CU240D PN
• CU240D PN-F
• CU240D PN-F PP（推拉）

  推拉型包含一种用于 24 V 电源电压和 PN 通信的替代连接方法。

  Safety Integrated 功能

  SINAMICS G120D 故障安全变频器提供了 3 个安全功能，它们都按照 EN 954-1（Cat 3）和 IEC 61508 SIL 2 进行了认证：

  • 安全转矩断开 (STO) 功能用于防止驱动器产生运动
  • 安全停止 1 (SS1) 功能用于连续监视一个安全制动斜坡
  • 安全限制转速 (SLS) 功能用于防止超过某个转速限值的危险移动

    “安全停止 1”和“安全限制转速”功能都无需使用电机编码器或编码器来执行，执行成本非常低。现有系统也可通过安全技术来更新，不需要改变电机或机械系统。

    安全功能“安全限制转速”和“安全停止 1”不能在使用起重机和退绕机的情况下用于穿设负载。

    已使用固件 V3.2 扩展了安全功能。

    有关详细信息，请参见“突出特点”一章的“安全集成”一节。

    功能

    Basic positioner (EPos)

    Overview

    • Absolute and relative positioning
    • Linear and rotary axis
    • Motor encoder or direct measuring system
    • 4 referencing modes
    • 16 traversing blocks
    • Direct setpoint input (MDI)
    • Jog mode
    • Backlash compensation
    • Following error monitoring
    • Cam signals

      The positioning functions are only available in the CU250D?2 Control Unit and are functionally identical to the positioning functionality of SINAMICSS110. Due to its flexibility and adaptability, the basic positioner can be used for a wide range of positioning tasks.

      The functions are easy to handle both during commissioning and during operation. Furthermore, they are characterized by their comprehensive monitoring functions.

      Many applications can be carried out without external position controllers.

      The EPos basic positioner is available as an additional function module that can be activated, and is used for the absolute/relative positioning of linear and rotary axes (modulo) with both rotary and linear motor encoders (indirect measuring system).

      User-friendly configuring and commissioning including control panel (operation using PC) and diagnostics with the STARTER commissioning tool V4.3 or higher.

      In addition to extremely flexible positioning functions, EPos offers a high degree of user-friendliness and reliability thanks to integral monitoring and compensation functions.

      Different operating modes and their functionality increase flexibility and plant productivity, for example, by means of "on-the-fly" and bumpless correction of the motion control.

      Preconfigured PROFIdrive positioning frames are available which, when selected, automatically establish the internal "connection" to the basic positioner.
