Hi All,
I am in the process of ordering an Acra 1440TVS. The lathe from the factory is spec’d with a Yaskawa G7series vfd that is not large enough to handle a single phase input. I have (and Tom at Acra has agreed) to have the VFD changed to a Yaskawa V1000 series CIMR-VU2A0030FAA to allow the full 5hp output on a single phase input. I asked about a DC choke and they don’t install them. I would plan to install a choke when I receive the machine. What else do I need to do? Change the fuses? How much amp service should I plan for? 40 or 50 amps single phase? Any programming changes. They will also install single phase oil and coolant pumps.
Thanks for the help.
Ed
