DETAILED PARAMETER DESCRIPTION
P0233 - Dead Zone
Adjustable range: 0 to 1 Factory setting: 1
Acesso: Menu → Configurations → I/O → Analog inputs
Description:
It defines if the Dead Zone in the Analog Inputs is 0 = Inactive or 1 = Active
If P0233 = 0 (Inactive), the signal in the Analog Inputs acts on the Speed Reference from the minimum point:
– (0 to 10) V/(0 to 20) mA/(4 to 20) mA:0 V/0 mA/4 mA.
– (10 to 0) V/(20 to 0) mA/(20 to 4) mA:10 V/20 mA/20 mA.
If P0233 = 1 (Active), the signal in the Analog Inputs has a dead zone, where the Speed Reference remains at
the value of the Minimum Value (P0133), even with the variation of the input signal.

If the analog input AI2 or AI4 is programmed for (-10 to +10) V (P0246 = 4), curves identical to those of the
Figure 5.28 on page 5-44, only when AI2 or AI4 is negative will the direction of rotation be inverted.
