Overclocking a 60's FP1 - New VFD.

So I found a correctly sized VFD for my FP1 that I can mount on the machine where I can get at it, instead of the 7.5HP unit that resides on the floor. This means setting up the new Hitachi VFD with limits. The old one was set to 60Hz max - it still has the original Siemens motor.

Has anybody set their VFD higher than 60Hz and does anybody have an opinion on setting it higher. Usually it is set and forget so this will be an opportune moment.

Thanks
