確保按照驅動器安裝說明正確接地電機電纜。注意：如果屏蔽未接地，電源電纜的屏蔽上可能存在高壓。確認電源電纜中所有屏蔽都接地。8 MP系列75 mm或更小框架尺寸的低慣量無刷伺服電機羅克韋爾自動化出版物MP-IN006D-EN-P-2015年1月電力電纜屏蔽制動控制和功率調節(jié)永磁制動器的直流電源，例如75 mm（2.95 in.）或更小框架的MP系列伺服電機，需要低紋波電壓的直流電源。電機制動器需要繼電器觸點來打開和斷開制動器線圈的電源。斷電會導致制動器機械接合，但也會導致觸點處產生電弧，直到剩余制動功率充分消散。建議使用客戶提供的二極管，以防止制動器繼電器觸點處產生電弧。用金屬氧化物變阻器（MOV）代替二極管可以減少機械接合制動器的時間。下圖顯示了客戶提供的用于制動控制的典型部件，包括消弧二極管或MOV。電機制動電路中的電弧抑制羅克韋爾自動化公司的Kinetix 6000驅動器有一個制動控制繼電器，包括MOV電弧抑制器。在這種情況下，不需要客戶提供的電弧抑制，除非制動器的功耗需要外部制動器繼電器。電力電纜內的屏蔽信號線（兩根）整體電力電纜屏蔽回路信號屏蔽（兩根中的一根）至整體電力電纜防護。
MP series low inertia brushless servo motor with 75 mm or smaller frame size 7 Rockwell Automation publication MP-IN006D-EN-P-2015 January, all equipment was grounded by using a single point parallel grounding system with grounding bus or large bus. If necessary, use additional electrical noise reduction techniques to reduce EMI in noisy environments. For more information on reducing EMI impacts by improving system level electromagnetic compatibility (EMC), refer to the Electrical Noise Control System Design Reference Manual, publication GMC-RM001. Building and installing cables Correct cable routing and careful cable construction can improve the electromagnetic compatibility (EMC) of the system. Make and install the cable according to the following guidelines: Keep the wire length as short as possible. Keep noise sensitive wiring (encoder, serial, and I/O) away from input power and motor power wiring. For parallel runs every 9 meters (30 feet), separate the cables at least 0.3 meters (1 foot) apart. Ground both ends of the encoder cable shield and twist the signal pair to prevent EMI from other equipment. Shield the power cord Follow the steps below to shield the power cord. 1. As shown in the figure, verify whether the separate signal wire shield is connected to the whole chassis grounding by looping back each signal wire pair. 2. Clamp all three shields at the ground connection of the power cord (chassis) on the drive together. Note: 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: The leakage current generated by MP series motors in the protective grounding conductor exceeds 3.5 mA AC and/or 10 mA DC.
Make sure that the motor cable is properly grounded according to the driver installation instructions. Note: 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. 8 MP series low inertia brushless servo motor with 75 mm or smaller frame size Rockwell Automation Publication MP-IN006D-EN-P-2015 January DC power supply of power cable shield brake control and power regulation permanent magnet brake, such as MP series service motor with 75 mm (2.95 in.) or 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 (MOVs) can reduce the time for mechanical brake engagement. The following figure shows the typical components provided by the customer for braking control, including arc suppression diode or MOV. Arc suppression in motor brake circuits Rockwell Automation's Kinetix 6000 driver has a brake control relay that includes a MOV arc suppressor. In this case, the arc suppression provided by the customer is not required, unless the power consumption of the brake requires an external brake relay. Shielded signal lines (two) in the power cable shield the signal shield of the overall power cable shield loop (one of the two) to the overall power cable protection.
