This.
Unless you have a spindle with lots of torque (I.e. milling machine/lathe spindle that's been geared down from a multiple KW motor), then holding the spindle with your hand will be enough to stop it from spinning up.
Plus most VFD manufacturers advise against regularly power cycling VFDs.
If you were worried about damage, I'd put the risk of crush injuries on any reasonably sized/powered CNC, far higher than a spindle starting up when you've got your hands near it.Avoiding the rubbish customer service from AluminiumWarehouse since July '13.
