Note
Activate the motorized potentiometer as ramp-function generator to use the motorized
potentiometer of the inverter as setpoint for the hibernation mode.
• Motorized potentiometer: p1030.4 = 1
• Technology motorized potentiometer: p2230. = 1.

Description
Hibernation mode restart speed (rpm)
Required for external setpoint input. The motor starts as soon as
the setpoint exceeds the restart speed. The restart speed is
calculated as follows:
Restart speed = p1080 + p2390 + p2393
p1080 = minimum speed
p2390 = hibernation mode start speed
p2393 = hibernation mode restart speed
Hibernation mode boost duration
0 (factory setting) ... 3599 s. Before the inverter switches over
into the hibernation mode, the motor is accelerated for the time
set in p2394 according to the acceleration ramp, however, as a
maximum to the speed set in p2395.
Hibernation mode boost speed
0 (factory setting) ... 21000 rpm. Before the inverter switches
over into the hibernation mode, the motor is accelerated for the
time set in p2394 according to the acceleration ramp, however,
as a maximum to the speed set in p2395.
Caution:
The boost may not result in any overpressure or overrun.
Maximum hibernation mode shutdown time
0 (factory setting) to 863,999 s. At the latest when this time ex-
pires, the inverter switches to normal operation and accelerates
up to the start speed (p1080 + p2390). If the inverter is switched
to normal operation in advance, the shutdown time is reset to
the value set in this parameter.
With p2396 = 0, automatic changeover to normal operation after
a certain time is deactivated.
