I have been working on a new CNC lathe build. Have a spindle setup from and old pneumatic controlled lathe.
I have had problems with getting the Haun Yang VFD working with the Baldor 5HP motor.
Motor was set to high voltage mode and I rewired for low voltage mode. The motor has a Brake and Clutch, runs the lathe spindle through v belts
With the VFD the motor spins but when the clutch is turned on the lathe spindle spins a second or so then the VFD errors with E.OC.n
Error is over current so I wonder if the VFD is too small. It is the 5HP one advertised to run a 5HP motor
Baldor motor 5HP
208-230 volts
15-13.2 amps
rpm 1725
hz 60
3 phase
I was hoping to be able to set it to the optimal programmed parameters. Would someone post a set of parameters for this specific motor? I have it set up with the set of parameters from page 10 of this thread.
How do I know if the VFD is too small for the motor.
Huan Yang VFD model:
HY04D023B
3PH 0~220AC 4.0KW 18A 0.50-400.00HZ
