Description: Sets the motor restart time with the "Hibernation" function.
If hibernation is active, the technology controller continues to operate and supplies a speed setpoint to the setpoint
channel. Since the drive is de-activated, there is no system deviation at the input of the technology controller. As
soon as this exceeds the restart value p2392, the drive is automatically powered up and the speed is controlled to
1.05 * (p1080 + p2390) via the up ramp of the setpoint channel.
Note: The restart value is set to 5 % when commissioning is completed.
Description: Sets the motor restart speed with the "Hibernation" function.
If hibernation is active a speed setpoint is still supplied to the setpoint channel. If the setpoint increases again and in
so doing exceeds the restart speed, the drive is automatically powered up and the speed setpoint is controlled to
p1080 + p2390 + p2393 via the up ramp of the setpoint channel.
The restart speed is the sum of the minimum speed p1080, the hibernation start speed p2390 and the relative
restart speed p2393.
Dependency: Refer to: p1080
Note: The parameter is set to 6 % of the nominal speed when commissioning is exited.
Description: Sets the boost time period for the "Hibernation" function.
Before the drive is finally powered down (goes into hibernation), the setpoint speed is moved to the boost speed
p2395 for the time set in p2394. Depending on the application, this allows the hibernation intervals to be extended
(in time).
Caution: The controller is not operational while the boost speed is being impressed. As a result, for example, for pump appli-
cations, it must be ensured that the tank does not overflow as a result of the additional boost. For compressors, it
must be ensured that the boost speed does not result in an overpressure condition.
Note: If a boost speed is not approached, then the boost time period is set to 0 s.
