7.7 Application-specific functions
● When the setpoint setting is entered from the technology controller, the technology
controller deviation (r2273) is monitored and the motor is switched on if the deviation of
the technology closed-loop controller exceeds the hibernation mode restart value
(p2392).
In the factory setting, only the positive deviation of the technology closed-loop controller
is monitored, i.e. the motor is switched on as soon as the technology closed-loop
controller deviation is greater than the hibernation mode restart value (p2392).
To switch the motor back on for negative technology closed-loop controller deviation, the
value of the deviation must be monitored.
Set p2298 = 2292 and set the minimum threshold in p2292.
Note
Hibernation mode after switching on the inverter
After switching the inverter on, a waiting period starts in the inverter. The waiting period is at
most the following times:
• p1120 (ramp-up time)
• p2391 (hibernation mode delay time)
• 20 s
If the motor does not reach the hibernation mode start speed within this wait time, the
inverter activates the hibernation mode and switches off the motor.
Additional setting options are provided in the List Manual in function block diagram 7038 and
in the associated parameter descriptions.
If you want to prevent frequent activation and deactivation, before deactivation you still have
to set a short speed boost. The boost is deactivated with p2394 = 0.
To avoid tank deposits, particularly where liquids are involved, it is possible to exit the
hibernation mode after an adjustable time (p2396) has expired and switch to normal
operation.
The settings required for the respective variant can be found in the following tables.
