This parameter is used to drive the control valve to the mechanical
end stops. If the parameter is not activated, the control valve controls
to the end positions which were determined during the initialization.
With tight closing, the control valve requires longer to leave the end
stops. With fast closing, the end stops of the control valve are left
immediately.
The tight closing and fast closing functions are activated on one side
or for both end positions. Parameter '39.YCLS' becomes effective
if the effective setpoint:
● Is at or below the value set in the '40.YCDO' parameter.
● Is at or above the value set in the '41.YCUP' Value for tight
closing/fast closing Up (Page 158) parameter.
