Claim 11:
12. A control system for a rotational system including a drive motor, the control system comprising:
an input adapted to receive an indication of a motor performance parameter;
an output adapted to output a high frequency pulse width modulation (PWM) drive motor signal to the drive motor;
a controller operably coupled to the input and to the output, the controller adapted to provide to the output the high frequency PWM signal for operating the drive motor;
the controller further adapted, when the motor performance parameter approaches a limit of a performance range, to add a low frequency PWM signal to the high frequency PWM drive signal that is provided to the drive motor via the output, thereby causing the drive motor to produce a tactile signal that signals to a user that the motor performance parameter is approaching the limit of the performance range.
