7.7 Application-specific functions
Parameter Description
p2394 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.
p2395 Energy-saving mode boost speed
0 (factory setting) to 21,000 rpm.
Before the inverter switches over into the 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 must not result in any overpressure or overflow.
p2396 Maximum hibernation mode shutdown time
0 (factory setting) to 863,999 s.
At the latest when this time expires, the inverter switches to normal opera-
tion 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 switchover to normal operation after a certain
time is deactivated.
