Tolerance Band And Hysteresis - BONFIGLIOLI Vectron ACTIVE Manual

5.1.6
The analog input characteristic with change of sign of the reference value can be
adapted by the parameter
to be defined extends the zero crossing of the speed relative to the analog control
signal. The percentage parameter value is relative to the maximum current or voltage
signal.
No.
560 Tolerance band
The
factory extend the parameterized tolerance band to the hysteresis.
For example, the output variable coming from the positive input signals is kept at the
positive minimum value until the input signal becomes smaller than the value for the
tolerance band in a negative direction. Only then is there continuation on the set char-
acteristic.
