p2394
Energy-saving mode boost duration
0 (factory setting) … 3599 s. Before the inverter switches over into the energy-
saving mode, the motor is accelerated for the time set in p2394 according to
the acceleration ramp, but not to more than the speed set in P2395.

p2395
Energy-saving mode boost speed
0 (factory setting) … 21000 rpm. Before the inverter switches over into the
energy-saving mode, the motor is accelerated for the time set in p2394
according to the acceleration ramp, but not to more than the speed set in
p2395.
Caution:
The boost may not result in any overpressure or overrun.

p2396
Maximum energy-saving mode shutdown time
0 (factory setting) … 863999 s. At the latest when this time expires, the
inverter switches to normal operation and is accelerated 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.
