Tips: Variable Frequency Drive Wiring Specification Standard
Signal line and power line must be separated: When using analog signals for remote control of the VFD, in order to reduce interference, the signal line and strong circuit (main circuit and sequential circuit) should be separated, and the distance should be above 30cm. Even in the control cabinet, the wiring specification should be maintained. The maximum length of the control circuit between the signal and the VFD should not exceed 50m.
Signal lines and power lines must be placed in different metal conduits or metal hose: If the PLC and the VFD signal line are not placed in metal conduit, it will be easily affected by the external interference and VFD. For there is no built-in reactor, the VFD input and output power line will have a strong interference on the outside, so the metal conduit or metal hose must be extended to the VFD control terminal to ensure that the signal line thoroughly separate from the power line.
- Analog control signal line should be used double stranded shielded wire, wire size 0.75mm2. In the wiring must note that the cable stripping should be as short as possible (5-7mm). The stripped shield layer should be wrapped with insulating tape to prevent introduce interference from shielded cable and other equipment.
- In order to improve the wiring simplicity and reliability, the signal line using pressure wire rod terminal is recommended.
