Repeated Stopping Accuracy

Repetitive stopping accuracy is an amount of variation in stopping position.
Please note that it is not an overrun amount(the rotation amount from the beginning of decelaration to a stop).
(Note) Stopping with a brake is a condition, when repetitive stopping accuracy value is input.
