Purpose: Use this parameter to activate continuous monitoring of the upper
endstop. Monitoring is always carried out if the '38.YCUP' Upper
value for tight closing / fast closing (Page 152) parameter is set to
one of the following values: 'uP', 'uP do', 'Fu', 'Fu Fd', 'uP Fd', 'Fu do'
It checks whether the upper endstop has changed compared to its
value during initialization. Monitoring is performed in three steps.
Set the following sub-parameters appropriately. To activate moni‐
toring, set the parameter to 'On'. Sub-parameters are displayed.
The value is displayed in Diagnostic value '19.OPEN - Upper end‐
stop' (Page 264). The positioner triggers a message if the current
value exceeds one of the three thresholds.
Factory setting: OFF
G1.LEVL1 - threshold 1
Adjustment range: 0.1 ... 10.0
Purpose: Use this sub-parameter to set threshold 1 for the upper endstop in
percent. Set the threshold in a range from '0.1' to '10.0'.
The positioner triggers a threshold 1 message if the difference be‐
tween the upper endstop and the initialization value exceeds thresh‐
old 1. This message is only output if threshold 2 or 3 is not exceeded
at the same time. The process to activate and display this message
is described in the 'XDIAG' parameter.
Factory setting: 1.0
G2.LEVL2 - threshold 2
Adjustment range: 0.1 ... 10.0
Purpose: Use this sub-parameter to set threshold 2 for the upper endstop in
percent. Set the threshold in a range from '0.1' to '10.0'.
The positioner triggers a threshold 2 message if the difference be‐
tween the upper endstop and the initialization value exceeds thresh‐
old 2. This message is only output if threshold 3 is not exceeded at
the same time. The process to activate and display this message is
described in the 'XDIAG' parameter.
Factory setting: 2.0
