i have a problem in my 22kw compressor vsd,compressor motor gives vibration and rhythmical humming once it is driven via vsd.what is the reason.is there any remedy for that while changing VSd parameters
For problems like that maybe it's due to your mechanical side. For the vsd parameter there are no settings that can change the vibration or hum. If the problem is with vsd maybe it's due to life time. I will give the life time of each part. If it is outdated then I suggest you to try to replace the part. 1. Fan : 2-3 years (20000 hour) 2. Electrolytic capacitor : 4-5 years 3. PCB : 5-8 years 4. Fuse 10 years I hope this can help you
@@lukmanabdulrasyid also we remove compressor air end and the motor to check rhe bearings..after replacing all the bearings if the sound remains as the sams..then can assume that there is a problem with the VSD
