CP.17 adjusts a zero point hysteresis of the setpoint input REF1. Voltage fluctuations
and ripple voltages near the zero point of the setpoint do not cause the motor to shift.

This function has a switching hysteresis of 50%. If the analog signal is larger than the
adjusted hysteresis value (CP.17), then the analog value is active. If the analog signal
goes below 50% of the adjusted hysteresis value (0.5 x CP.17), then the analog
setpoint is set at 0.
