Description: Setting to invert the fault signal of the technology controller.
The setting depends on the type of control loop.
Value: 0: No inversion
1: Inversion
Caution: If the actual value inversion is incorrectly selected, then the closed-loop control with the technology controller can
become unstable and can oscillate!
Note: The correct setting can be determined as follows:
- inhibit the technology controller (p2200 = 0).
- increase the motor speed and in so doing, measure the actual value signal (of the technology controller).
- if the actual value increases with increasing motor speed, then the inversion should be switched out.
- if the actual value decreases with increasing motor speed, then the inversion should be set.
If value = 0:
The drive reduces the output speed when the actual value rises (e.g. for heating fans, intake pump, compressor).
If value = 1:
The drive increases the output speed when the actual value increases (e.g. for cooling fans, discharge pumps).
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
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
