These problems can be reduced by the correct installation practices. I have a few suggestions and perhaps others can add to the list.
- Use a screened cable between the motor and the drive. Connect the screen to the motor using a screened gland and connect the screen to the drive using a screened gland.
- If the screened cable has an earth core, connect it to the earth terminal in the motor and in the drive.
- Connect all input/output control cables via screened cable terminated at the drive and the control end by screened glands.
- If the drive does not include an input filter, mount the correct filter as close to the input to the drive as possible. Bond the earth of the filter to the chassis of the drive as close as posible.
Add your rules also.
