Hello - I've got a Hitachi WJ200 hooked up with a 2.2kw Chinese spindle and I just added a 200W, 50 ohm braking resistor that I can't get to work right yet.

The problem seems to be with setting A052, which sets the DC braking frequency. This setting maxes out at 60Hz, but my spindle operates at 400Hz. Setting A052 to 60Hz does allow for braking once the spins down to 60Hz, but that can't be right.

Has anyone gotten this combination working together that could share the relevant settings?

Thanks,
Kent
