Tips: Variable frequency drive installation environment

Electrical use conditions:

To prevent electromagnetic wave interference. VFD (Frequency inverter) in the work due to rectification and frequency conversion, around a lot of interference electromagnetic waves, these high-frequency electromagnetic waves on the nearby instruments, instruments have a certain interference. Therefore, the cabinet instrumentation and electronic systems should be selected metal shell, shielding the VFD to instrumentation interference. All components should be reliably grounded, in addition to the electrical components, instruments and instruments between the connection should be selected shielded control cable, and the shielding layer should be grounded. If electromagnetic interference is not handled well, it will often make the whole system unable to work and lead to control unit malfunction or damage.

Ambient temperature:

The ambient temperature of the variable frequency drive refers to the temperature near the cross-section of the VFD. Since the VFD is mainly composed of high-power electronic equipment that is highly susceptible to temperature, the life and reliability of the VFD depends largely on the temperature, which is generally -10℃ to +40℃. In addition, need to consider the VFD's own heat dissipation and the possible extremes of the surrounding environment, for the temperature generally requires a certain amount of margin.

7.5 hp VFD

Is this VFD able to power a PMSM spindle with an encoder up to 800Hz? There will be about 20' of cable between the spindle and the VFD when mounted to the gantry on my cnc. Thank you.
