For p2372 = 2:
Motor selection for switching-in/switching-out is derived from the operating hours counter p2380. When switching-in,
the motor with the least operating hours is connected. When switching-out, the motor with the most operating hours
is disconnected.
In addition, those motors which have been in operation continuously for longer than the time set in p2381 are
interchanged automatically.
If p2371 = 4 (selection of three identical motors), the switch is only performed between two motors, if the required
input power of one single external motor is sufficient for the actual operating point.
For p2372 = 3:
Motor selection for switching-in/switching-out is derived from the operating hours counter p2380. When switching-in,
the motor with the least operating hours is connected. When switching-out, the motor with the most operating hours
is disconnected.
In addition, those motors which have been in operation for a total time longer than that set in p2382 are interchanged
automatically.
For p2372 = 2, 3:
This automatic interchange (autochange) is only possible if the designated motor is not in operation. If all motors are
in operation, the interchange will not be possible and alarm A07427 appears.
Autochange mode is only possible if p2371 = 2, 4 (motors of the same size).
Description: Threshold value for the delayed switching-in or non-delayed switching-out of external motors connected to the line.
Motor switching-in is activated if the maximum speed is reached and the wait time in p2374 has expired.
Dependency: Refer to: p2374
Description: Additional delay time for connecting external motors to the line voltage after the system deviation of the technology
controller has exceeded the threshold value p2373 and the motor has reached the maximum speed.
Dependency: Refer to: p2373
Note: If the deviation at the technology controller input exceeds the overcontrol threshold p2376, the delay time is
bypassed.
Description: Additional delay time for the disconnection of external motors from the line after the system deviation of the
technology controller has exceeded the threshold p2373 and the motor has reached the minimum speed p1080.
Dependency: Refer to: p2373, p2376
Note: If the deviation at the technology controller input exceeds the overcontrol threshold -p2376, the delay time is
bypassed.
