I have a 3hp ACRA mill with OEM Yaskawa V1000 VFD speed control. It is originally 380-480 3PH input. I reconfigured the motor to 230V configuration and purchased a chicom 230V VFD with either 1ph or 3ph input. I have an opportunity to pick up a Yaskawa 5.5kw 230V V1000 VFD for a reasonable price, but it requires 3ph input. I already have a 7.5hp RPC, so 230V 3ph is available. My question is would it be better to run the chicom VFD on 3ph input from my RPC? The input current would be less, right? Is the 5% voltage balance between the RPC legs acceptable for the 3ph VFD input?
I'm on the fence with the Yaskawa 230V VFD. It is used with no history. Missing covers, etc. To use it, i would need to run it from the RPC as it requires 3ph input.
The original 380-480 Yaskawa VFD was running in the mill when it was pulled from service. My long term plan is to have a step up xformer to have 460V 3ph available, but that plan is awaiting finding the correct 3ph xformer. Once i have 460V available, I'll reconfigure the mill motor back to 460V and reinstall the original Yaskawa VFD.
