This process is identical to [Default] (bSd) , but in the following cases
the frequency at reference = 0 is also = 0:
• The signal is below the [min value], which in turn is greater
than 0 (example: 1 V on a 2 to 10 V input)
•
The signal is above the [min value], which in turn is greater
than 0the [max. value] (Example: 11 V on a 0 to 10 V input)
If "bidirectional" has been set for the input field, the process is identical
to [Default] (bSd) .
This parameter defines how the speed reference is taken into account, for analog inputs and Pulse input only.
In the case of the PID regulator, this is the PID output reference. The limits are defined by the parameters
[low speed]
(LSP) and
[high speed]
(HSP) ( see "Parameters that can be modified during operation or when the motor is stopped." on page 130 ).
