Zero Point Hysteresis REF 1
A zero point hysteresis of the analog reference input REF1 is adjusted with this
parameter. Voltage fluctuations and ripple voltages around the zero point of the
setpoint value do not cause any drifting of the motor.

Example: If CP.17 is adjusted to 5 % then the drive
starts only at a setpoint value of +/- 0,5 V.
