What could the cause my external device to make a lot of noise, when installed next to an Altivar Process Drive?

Product Line:

All serial numbers for Altivar Process Drive (ATV630, ATV930, ATV650, ATV950, ATV660, ATV960, ATV680, ATV980)

Related to noise issues

Noise is typically not generated by the drive but in some cases here are a few things check:
[Complete settings] [Motor parameters] [Switching frequency]
- Switching Frequency [SFr] (Increasing may reduce noise but increase heat generated by the drive)
- Noise Reduction [nrd] 

NOTE: In the event of excessive temperature rise, the drive automatically reduces the switching frequency
and reset it once the temperature returns to normal.
In case of high-speed motor, it is advised to increase the PWM frequency [Switching frequency] SFr at
8, 12 kHz or 16 kHz

- Check for possible electrical interference from nearby devices
- Check installation cables
  Recommend the use of proper VFD or shielded cables in separate conduits. Refer to Installation Manual for Guide Lines.
