Note: Only p2251 = 0:
If the output signal of the technology controller reaches a skip band in the speed setpoint channel, then the integral
component of the controller is held, if at the same time, the system deviation is lower than the threshold value set
here. By holding the integral component, it can be avoided that the controller oscillates in the range of the skip bands.
r2344 CO: Technology controller last speed setpoint (smoothed) / Tec_ctrl n_setp_sm
Access level: 3
Can be changed: -
Unit group: -
Min
- [%]
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: Smoothing time = 10 s
p2345 Technology controller fault response / Tech_ctrl flt resp
Access level: 3
Can be changed: U, T
Unit group: -
Min
0
Description: Sets the response of the technology controller to the occurrence of fault F07426 (technology controller actual value
limited).
The fault response is executed if status bit 8 or 9 in the technology controller status word r2349 is set. If both status
bits are zero, a switch back to technology controller operation will follow.
Value: 0:
1:
2:
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
oscillations. In this case, a different 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).
