4. Parameter Description
Zero Point Hysteresis REF 1
GB
GB 26
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.
Adjustment Range:
Resolution:
Factory setting:
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.
