Description:
This parameter acts only for the analog inputs (AIx) programmed as speed reference, and it defines if the Dead Zone
at those inputs is On (1) or Off (0).
If the parameter is configured as Off (P0230 = 0), the signal at the analog input will work on the Speed Reference
starting from the minimum value (0 V / 0 mA / 4 mA or 10 V / 20 mA), and will be directly related to the minimum
speed programmed at P0133. Refer to the
If the parameter is configured as On (P0230 = 1), the signal at the analog inputs will have a Dead Zone, where
the Speed Reference remains in the minimum value (P0133), even with the variation of the input signal. Refer to the

In case that the analog inputs AI2 and AI4 are programmed for -10 V to +10 V (P0238 and P0248 configured in
4), there will be curves identical to those of the
the speed direction will be inverted.
