ErrorBit (DW#16#...)
Description
10000 Invalid value at the ManualValue parameter: Value has an invalid number
format.
The actuator cannot be moved to the manual value and remains in its cur-
rent position.
Assign a valid value in ManualValue or move the actuator in manual mode
with Manual_UP and Manual_DN.
20000 Invalid value at the SavePosition tag: Value has an invalid number format.
The actuator cannot be moved to the substitute output value and remains in
its current position.
40000 Invalid value at the Disturbance parameter: Value has an invalid number
format.
Note: If automatic mode was active and ActivateRecoverMode = FALSE
before the error occurred, Disturbance is set to zero. PID_3Step remains in
automatic mode.
Note: If pre-
tuning or fine tuning mode was active and ActivateRecoverMode
= TRUE before the error occurred, PID_3Step switches to the operating
mode that is saved in the Mode parameter. If Disturbance in the current
phase has no effect on the output value, tuning is not canceled.
The error has no effect during transition time measurement.
1
Note: If automatic mode was active before the error occurred and ActivateRecoverMode = TRUE,
PID_3Step remains in automatic mode.
2
Note: If pre-tuning, fine tuning, or transition time measurement mode were active and Acti-
vateRecoverMode = TRUE before the error occurred, PID_3Step switches to the operating mode
that is saved in the Mode parameter.
3
Note: If automatic mode was active before the error occurred and ActivateRecoverMode = TRUE,
PID_3Step switches to "Approach substitute output value with error monitoring" or "Error monitor-
ing" mode. As soon as the error is no longer pending, PID_3Step switches back to automatic
mode.
4
Note: If ActivateRecoverMode = TRUE before the error occurred, PID_3Step cancels the tuning
and switches to the operating mode that is saved in the Mode parameter.
5
The actuator cannot be moved to the substitute output value and remains in its current position. In
manual mode, you can change the position of the actuator only with Manual_UP and Manual_DN,
and not with ManualValue.
