AC servo driver wiring precautions

For signal line and encoder input line, please use shielded wire. Wiring length: the length of signal line from NC to AC servo driver is less than 3m, and the length of input line from AC driver to encoder is less than 20m. The ground wire should be thick wire as far as possible. According to the third grounding standard (grounding resistance < 100 Ω), one point grounding method should be adopted to connect the ground wire. If the motor and the machine tool are insulated, the motor should be grounded.

How good is the air conditioning dehumidification

Nowadays, the temperature of some air conditioners is set actively by the manufacturer during dehumidification. Under the dehumidification method of this type of air conditioner, the control circuit will first check the room temperature, and then set the operating temperature policy value. The setting value of the factory plan is usually the policy value of the operation arrival It is 2 degrees lower than the room temperature. If the setting is too high, the dehumidification effect is not significant. In order to prevent overheating and lowering the room temperature during dehumidification, this set value is usually judged. At this time, we do not need to set the temperature, just open the air conditioning dehumidification function.<img src="{{media url=&quot;How_good_is_the_air_conditioning_dehumidification.jpg&quot;}}" alt="" />
