I'm preparing an observation report for a VFD I installed about a year ago. Can you tell me if you see anything odd here? Looks OK to me but this will be on state records so I need more brain power.
Data plate
Input: 480V 50/60hz 40.6A
Output: 0-480V 0-60hz 34A
My readings are as follows with VFD operating at 57hz 480V out.
Input:
A?=43A
B?=38A
C?=36A
A-G=288V A-B=496V
B-G=281V A-C=488V
C-G=279V B-C=485V
Output amp right at 27-29A
Thanks.
