DeadZone
-
This parameter is active onlyfor the analog inputs (AIx) programmed as
speedreference.
When set to 1 enables the Dead Zone for theAnalog Inputs.
If P233 = 0 (Off) the “zero” signal at the Analog Inputs (0 V/0 mA/ 4 mA
or 10 V/20 mA) is directly related to the minimum speed programmed at
P133. Refer to figure 6.28 a).
If P233 = 1 (On) theAnalog Inputs have a “dead zone”, and the speed
reference remains at its minimum value (defined byP133) until theinput
signalreaches a levelproportional to theminimum speed. Refer to figure
6.28 b).

Parameter P232 is valid only for the following commands:
1) The key of the keypad;
2) Start/Stop function with 2-wire control (through DI1 = 1);
3) Start/Stop function with 3-wire control (refer to parameters from P265
to P270 for a complete description about the function 14).
In the V/F Mode the option 2 (Fast Stop) is not available.
