如果电机上安装了用于表面冷却的鼓风机，则还存在电机鼓风机连接。端子图中未显示这一点。INDRAMAT驱动器的电气连接已标准化，以尽量减少电缆多样性。12节和13节规定了给定应用和电机类型的电气连接。电源连接以下连接集成到电源连接中：•电源电缆•温度传感器（PTC）连接电缆•阻断制动器的连接电缆温度传感器内置在电机绕组中。通过评估控制器中的温度传感器，防止电机过热。如果电机因热原因停机，控制器将生成相应的错误消息。闭锁制动器由驱动控制器控制。电源连接的电机电源接头可用于压接或焊接。公制电缆直径的电力电缆可以压接或焊接到电机电源连接器上。直径为英寸的电力电缆只能焊接。反馈连接电机上有一个用于反馈连接的12针法兰套筒。13节概述了连接图、可用反馈电缆和反馈连接器。电机鼓风机连接电机鼓风机通过保护电机开关连接。这意味着它独立于控制器运行。有关电机鼓风机的更多信息，请参阅文档“用于安装到MDD伺服电机的鼓风机”，文档。编号9.578.003.4。

If a blower for surface cooling is mounted on the motor, then a motor blower connection is also present. This is not shown in the terminal diagram. The electrical connections of INDRAMAT drives have been standardized to minimize cable diversity. Sections 12 and 13 specify the electrical connections for a given application and motor type. Power connection The following connections are integrated into the power connection: • power cable • connecting cable for temperature sensor (PTC) • connecting cable for blocking brake The temperature sensor is built into the windings of the motor. The motor is protected against overheating by evaluating the temperature sensor in the controller. In the case of a motor shutdown for thermal reasons, the controller will generate the appropriate error message. The blocking brake is controlled by the drive controller. Motor power connectors for the electrical power connections are available either • for crimping or • soldering. Power cables with metric cable diameters can be either crimped or soldered to the motor power connector. Power cables with inch diameters can only be soldered. Feedback connection There is a 12-pin flanged socket on the motor for the feedback connection. The connection diagram, available feedback cables and feedback connectors are all outlined in section 13. Motor blower connection The motor blower is connected via a protective motor switch. This means it operates independently of the controller. Additional information about the motor blower can be found in the document "Blowers for mounting to MDD servo motors", doc. no. 9.578.003.4.
