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

Name
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 converter 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) ... 21,000 rpm. Before the converter
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
expires, the converter switches to normal operation and ac‐
celerates up to the start speed (p1080 + p2390). If the con‐
verter is switched to normal operation in advance, the shut‐
down time is reset to the value set in this parameter.
With p2396 = 0, automatic changeover to normal operation
after a certain time is deactivated.
