8.3.2.11 '38.YCUP' Value for tight closing/fast closing Up
Requirement: Parameter '36.YCLS (Page 150)' is set to 'uP', 'uP do', 'Fu',
'Fu Fd', 'uP Fd' or 'Fu do'
Adjustment range: 0.0 ... 100.0
Purpose: Use the parameter '38.YCUP' to set the value as of which
the tight closing Up or fast closing Up is activated. If the
effective setpoint is at or above the value set here, the ac‐
tuator moves in tight closing Up or fast closing Up.
Factory setting: 100.0
Note
The value in the parameter "37.YCDO (Page 151)" is always smaller than that in "38.YCUP".
The tight closing function has a fixed hysteresis of 1%. The parameter "38.YCUP" refers to the
mechanical stops. "38.YCUP" is independent of the value that is set in the parameters "6.SDIR
(Page 145)" and "35.YDIR (Page 150)".
8.3.2.12 '38.YCUP' Upper value for tight closing / fast closing
Requirement: ' 36.YCLS' Tight closing/fast closing with manipulated variable
(Page 150) Parameter is set to 'do', 'uP do', 'Fd', 'Fu Fd', 'uP Fd' or
'Fu do'
Adjustment range: 0.0 ... 100.0
Purpose: Use the 'YCUP' parameter to set the value as of which the tight
closing Up or fast closing Up is activated. If the effective setpoint is
at or above the value set here, the actuator moves in tight closing
Up or fast closing Up.
Factory setting: 99.5
Note
The value in the 'YCDO' parameter is always smaller than that in 'YCUP'. The tight closing/fast
closing function has a fixed hysteresis of 1%. The 'YCUP' parameter is relative to the
mechanical stops. The 'YCUP' is independent of the values set in the '6.SDIR' Setpoint
direction (Page 145) and '35.YDIR' Direction of action of manipulated variable for display and
position feedback (Page 150) parameters.
