do cnc surface grinders heads drop unexpectedly/Okamoto Grinder

This grinder has a dial on the control panel which allows the operator to spin. It raise or lowers the grinding head at what ever speed your finger spins it. I have noticed that if it is spun fast, the head lags behind and sometimes does't move at all. Then the head may drop with out notice. Does this mean the controller may be bad?
