Parameter
p2394
p2395
p2396
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.
Status of the hibernation mode
Parameter Description
r2273 Display of the setpoint/actual value deviation of the technology controller
r2397 Actual hibernation mode output speed
Actual boost speed before the pulses are inhibited or the actual start speed after restart.
r2399 Hibernation mode status word
00 Hibernation mode enabled (p2398 <> 0)
01 Hibernation mode active
02 Hibernation mode delay time active
03 Hibernation mode boost active
04 Hibernation mode motor switched off
05 Hibernation mode motor switched off, cyclic restart active
06 Energy-saving mode motor restarts
07 Hibernation mode supplies the total setpoint of the ramp-function generator
08 Hibernation mode bypasses the ramp-function generator in the setpoint channel

Description
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 maxi‐
mum to the speed set in p2395.
Hibernation mode boost speed
0 (factory setting) ... 21,000 rpm. Before the inverter switches
over to hibernation mode, the motor is accelerated for the time
set in p2394 along the acceleration ramp, but not to more than
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.
