Function:
Sets the time desired as minimum run time after a normal start command (Start/Jog/Freeze). Any
normal stop command will be disregarded until the set time has expired. The timer will start counting
following a normal start command (Start/Jog/Freeze).
The timer will be overridden by a Coast (Inverse) or an External Interlock command.
Function:
Disabled
[0] : Setpoint compensation not active.
Enabled
[1] : Setpoint compensation is active. Enabling this parameter allows the Flow Compensated
Setpoint operation.
Function:
Example 1:
Adjustment of this parameter allows the shape of the control curve to be adjusted.
0 = Linear
100% = Ideal shape (theoretical).
