8.1.5 Tolerance Band and Hysteresis

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 parameter value (percent) is relative to the maximum current or voltage
signal.

For example, the output variable coming from positive input signals is kept on the
positive minimum value until the input signal becomes lower than the value for the
tolerance band in the negative direction. Then, the output variable follows the set
characteristic.
