Tolerance Band And Hysteresis - BONFIGLIOLI Vectron Manual

6.1.5
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.

For example, the output variable resulting from the positive input signals is kept at the
positive minimum value until the input signal is below the value for the tolerance band
in a negative direction. After that proceed on the set characteristic.
