I was thinking the machine might have more torque at lower RPM if I used a CT capable drive of the appropriate size instead of the factory VFD, which I understand is a VT set up. Am I wrong? The installed VFD is a Yaskawa MC5.
Right now the spindle max speed is just over 5000, which I interpret to mean I'm running on the low range.
If there's a screen or routine to do probing on the Centurion 6, I haven't found it yet. Maybe it needs to be enabled?
I had to replace a home switch on the Y, but other than that it's "just worked". Best machine tool buy yet.
edit: Forgot to mention... I was talking about additional torque at low speeds, like rigid tapping seems to use. I do have rigid tapping installed.
