General stepper motor question:
Is it safe to manually turn a stepper motor that is energized (holding at a fixed position)? Or could it damage the motor in some way?
I'm working on an old stage based system that uses stepper motors to move the axes. Each of the axes has a knob on the end that I can use to move the stage position manually, but when the system is energized I'm afraid it will damage something if the knob is turned. When the system is not energized it's very easy to turn the knob, so I'm assuming it might damage the motor to turn it while holding.
Thanks in advance.
