0 (factory setting) … 19500 rpm. Lower limit of the motor speed is
independent of the speed setpoint.

p2390
Energy-saving mode start speed
0 (factory setting) … 21000 rpm. As soon as this speed is fallen below, the
energy-saving mode delay time starts and switches off the motor once it
expires. The energy-saving mode start speed is calculated as follows:
Start speed = p1080 + p2390
p1080 = minimum speed
p2390 = energy-saving mode start speed.
x x
p2391
Energy-saving mode delay time
0 ... 3599 s (factory setting: 120). The energy-saving mode delay time starts
as soon as the output frequency of the inverter drops below the energy-saving
mode start speed p2390. If the output frequency increases above this
threshold during the delay time, the energy-saving mode delay time is
interrupted. Otherwise, the motor is switched off after the delay time has
expired (if necessary, after a short boost).

p2392
Energy-saving mode restart value (percentage)
is required if the technology controller is used as the main setpoint.
As soon as the technology controller deviation (r2273) exceeds the energy-
saving mode restart value, the inverter switches to normal operation and the
motor starts with a setpoint of 1.05 * (p1080 + p2390). As soon as this value is
reached, the motor continues to operate with the setpoint of the technology
x
p2393
Energy-saving mode restart speed (rpm)
is required for external setpoint setting. 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 = energy-saving mode start speed
p2393 = energy-saving mode restart speed
