Overshoot in position signal which grows over time
It is possible that the position of the motor may show an overshoot when driven with
a large square wave or similar, and that this overshoot will grow with time until a fault
is triggered. There is usually a certain frequency and amplitude above which this
starts to occur. This behaviour is caused by choosing a power supply which cannot
deliver enough current for the intended application. The oscillation builds up because
the power supply voltage is dropping on the rising edge of the position signal and
effecting the board's behaviour. With every rising edge the effect becomes slightly
greater as the overshoot grows.
