Lim' Response Threshold Of Fault Message 'Control Deviation - Siemens SIPART PS2 Operating Instructions Manual

Parameter assignment
9.4 Description of parameters
Note
Activated tight closing function
If the tight closing function is activated, then for the '49.
control deviation is turned off in the appropriate overflow direction. Then 'YCDO: < 0 %' and
'YCUP: > 100 %'. This functionality is especially advantageous for valves with lining. For
long-term monitoring of the endstop positions, we recommend activating the 'F.
'G. OPEN' parameters.

This parameter is used to set a value for the permissible size of the
control deviation to trigger a fault message. The value is given in
percent.
If the '48. TIM' and '49. LIM' parameters are set to 'Auto', then the
fault message is set if the slow step zone is not reached within a
certain period of time. Within 5 to 95% of the actuator travel, this
time is twice the initialization travel time, and ten times the initializa-
tion travel time outside of 10 to 90%.
