Positioning of the servo driver

　　Servo system, you know the servo drive grounding to pay attention to what matters? The following with Xiaobian together to see.

　　Servo drive ground 8 precautions are as follows:

　　① The correct shield is located at the reference potential point inside its circuit, servo driver depending on whether the noise source and the reception are grounded at the same time, or floating.

　　② Make sure that the shield is grounded at the same point so that the ground current does not flow through the shield.

　　③ to avoid a variety of ground connection generated by the ground circuit is susceptible to noise and in different reference point to generate current.

　　④ In the case where there is no isolation between the AC power supply and the DC bus of the driver, servo driver the non-isolated port or non-isolated signal of the DC bus can not be connected to the ground, which may cause equipment damage and personal injury.

　　⑤ avoid the servo drive connected to the external power supply, will directly affect the controller and drive work.

　　⑥ exchange of public voltage is not on the earth, in the DC bus and the earth may be between the high voltage, prohibit direct grounding.

　　⑦ in the servo system, servo driver the public and the earth must be connected at the signal side.

　　⑧ In order to keep the command reference voltage constant, servo driver the signal of the servo driver is connected to the signal ground of the controller.
