Description: Displays the smoothed speed setpoint of the technology controller prior to switching to operation with fault response
(see p2345).
Dependency: Refer to: p2345
Note: The smoothing time is 10 s.
Description: Sets the response of the technology controller to the occurrence of a fault F07426 (technology controller actual
value limited). The fault response is executed if status bits 8 or 9 in technology controller status word r2349 are set.
If both status bits are zero, a switch back to technology controller operation will follow.
Value: 0: Function inhibited
1: On fault: Changeover to r2344 (or p2302)
2: On fault: Changeover to p2215
Dependency: The parameterized fault response is only effective if the technology controller mode is set to p2251 = 0 (technology
controller as main setpoint).
Refer to: p2267, p2268, r2344
Refer to: F07426
Notice: Dependent upon the application, the changing over of the setpoint when fault F07426 occurs can lead to the fault
condition disappearing and the re-activation of the technology controller. This can repeat itself and cause limit oscil-
lations. In this case a suitable fault response or a different fixed setpoint 15 for the fault response p2345 = 2 should
be selected.
Note: The parameterized fault response can only be achieved if the default fault response of the technology controller
fault F07426 is set to "NONE" (see p2100, p2101). If a fault response other than "NONE" is entered in p2101 for
F07426, p2345 must be set to zero.
If the fault occurs during ramping up to the starting setpoint p2302, this starting setpoint is retained as the final value
(there is no changeover to the fault response setpoint).
