从电机安装面施加杠杆以移除安装在电机轴上的设备可能会损坏反馈装置。在安装或拆卸过程中，不要用工具敲击联轴器或皮带轮。使用车轮拉拔器从轴的用户端施加压力，以从电机轴上移除任何摩擦配合或卡住的装置。系列或更小框架尺寸的低惯量无刷伺服电机年月通过使用接地母线或大母线的单点并联接地系统对所有设备进行接地。如有必要，使用额外的电气降噪技术来减少噪声环境中的。有关通过提高系统级电磁兼容性来减少影响的更多信息，请参阅《电气噪声控制系统设计参考手册》。构建和安装电缆正确的电缆布线和小心的电缆结构可提高系统电磁兼容性。按照以下指南制作和安装电缆尽量缩短电线长度。将噪声敏感接线编码器和远离输入电源和电机电源接线。对于每米英尺的平行敷设，将电缆至少分开米英尺。将编码器电缆屏蔽的两端接地，并扭转信号线对，以防止来自其他设备的。屏蔽电源线按照以下步骤屏蔽电源线。如图所示，通过回圈每个信号线对，验证单独的信号线屏蔽是否连接到整个机箱接地。将驱动器上的电源线机箱接地连接处的所有三个屏蔽夹在一起。注意如果屏蔽未接地，电源电缆的屏蔽上可能存在高压。确认所有电源电缆屏蔽都接地。注意系列电机在保护接地导体中产生的泄漏电流超过和或。确保按照驱动器安装说明正确接地电机电缆。注意如果屏蔽未接地，电源电缆的屏蔽上可能存在高压。确认电源电缆中所有屏蔽都接地。系列或更小框架尺寸的低惯量无刷伺服电机年月电力电缆屏蔽制动控制和功率调节永磁制动器的直流电源，例如或更小框架的系列伺服电机，需要低纹波电压的直流电源。电机制动器需要继电器触点来打开和断开制动器线圈的电源。断电会导致制动器机械接合，但也会导致触点处产生电弧，直到剩余制动功率充分消散。建议使用客户提供的二极管，以防止制动器继电器触点处产生电弧。用金属氧化物变阻器代替二极管可以减少机械接合制动器的时间。下图显示了客户提供的典型制动控制部件，包括消弧二极管或。
Applying a lever from the motor mounting surface to remove equipment mounted on the motor shaft may damage the feedback device. Do not knock the coupling or pulley with tools during installation or removal. Use the wheel puller to apply pressure from the user end of the shaft to remove any friction fit or stuck devices from the motor shaft. The low inertia brushless servo motor of series or smaller frame size is used to ground all equipment through a single point parallel grounding system using a grounding bus or a large bus. If necessary, use additional electrical noise reduction technology to reduce noise in the environment. Refer to the Electrical Noise Control System Design Reference Manual for more information on reducing impacts by improving system level EMC. The construction and installation of cables Correct cable routing and careful cable construction can improve the electromagnetic compatibility of the system. Follow the guidelines below to make and install cables to minimize wire length. Connect the noise sensitive wire to the encoder and the wire away from the input power supply and motor power supply. For parallel runs per meter foot, separate the cables at least meters feet apart. Ground both ends of the encoder cable shield and twist the signal wire pair to prevent from coming from other equipment. Shield the power cord Follow the steps below to shield the power cord. As shown in the figure, verify whether the separate signal wire shield is connected to the whole chassis ground by looping back each signal wire pair. Clamp all three shields together at the power cord chassis ground connection on the drive. Note that if the shield is not grounded, there may be high voltage on the shield of the power cable. Verify that all power cable shields are grounded. Note that the leakage current generated by the series motor in the protective grounding conductor exceeds and or. Make sure that the motor cable is properly grounded according to the driver installation instructions. Note that if the shield is not grounded, there may be high voltage on the shield of the power cable. Verify that all shields in the power cable are grounded. Low inertia brushless servo motor of series or smaller frame size DC power supply for shielding brake control and power regulation permanent magnet brake of power cable, such as series servo motor of smaller frame, requires low ripple voltage DC power supply. The motor brake requires relay contacts to open and disconnect power to the brake coil. De energizing causes the brakes to engage mechanically, but also causes arcing at the contacts until the residual braking power is sufficiently dissipated. Customer supplied diodes are recommended to prevent arcing at the brake relay contacts. Replacing diodes with metal oxide varistors can reduce the time for mechanical brake engagement. The following figure shows typical brake control components provided by the customer, including arc suppression diodes or.
