Description: Display and connector output for the output signal of the adaption of integral time Tn for the technology controller.
Dependency: Refer to: p2252, p2317, p2318, p2319, p2320, p2321
Note: Tn adaptation is activated with p2252.8 = 1.
Description: Sets the threshold value for the system deviation of the technology controller, which controls holding the controller
integral component in the range of the skip speeds of the ramp-function generator.
Recommendation: To avoid speed setpoint steps in the range of the skip speeds, we recommend setting p2252 bit 4 = 1 (ramp-function
generator bypass deactivated).
Dependency: The parameter has no effect for p2252 bit 5 = 1 (integrator hold deactivated).
Refer to: r2273
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.
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
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: Function inhibited
1: On fault: Changeover to r2344 (or p2302)
2: On fault: Changeover to p2215
