Description: Sets the start speed for the hibernation function.
The total speed of this activation threshold is the sum of the minimum speed p1080 and p2390.
If the speed setpoint undershoots this start speed, the delay time in p2391 is started. If the restart threshold is no
longer reached before the delay time expires, the hibernation boost speed p2395 is impressed for the time period
p2394 and then the motor is brought to a standstill via the down ramp of the setpoint channel. The drive is powered
down (hibernation active). The drive is automatically powered up again as soon as the speed setpoint exceeds the
restart threshold.
Note: The hibernation start speed is set to 4 % of the nominal speed/frequency when commissioning is completed.
Example:
Nominal frequency 50 Hz: p2390 = 4 % * 50 Hz = 2 Hz
Description: Sets the delay time for the "Hibernation" function.
To ensure that the drive can be shut down (pulse inhibit), a restart condition must not occur during this time.
Dependency: Refer to: p2390, p2392, p2393
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 deactivated, 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: On completion of commissioning, the restart value (technological variable) is set to 5% of the nominal value of the
PID base value in p0596.
Example:
p0596 = 1000 bar: p2392 = 5 % * 1000 bar = 50 bar
