Setting the hibernation mode
Parameter Description
p1080 Minimum speed
0 (factory setting) ... 19500 rpm.
Lower limit of the motor speed is independent of the speed setpoint.
p1110 Block negative direction
Parameter to block the negative direction.
p2200 Technology controller enable
0: Technology controller deactivated (factory setting)
1: Technology controller activated
p2251 = 1 Technology controller mode
0: Technology controller as main setpoint (factory setting)
1: Technology controller as supplementary setpoint
p2298 Technology controller minimum limiting
Parameter for the minimum limiting of the technology closed-loop controller.
p2398 Hibernation mode
0: Hibernation mode inhibited (factory setting)
1: Hibernation mode enabled
p2390 Hibernation mode start speed
0 (factory setting) ... 21,000 rpm.
As soon as this speed is fallen below, the hibernation mode delay time starts
and switches off the motor once it expires. The hibernation mode start speed
is calculated as follows:
Start speed = p1080 + p2390
p1080 = minimum speed
p2390 = hibernation mode start speed
p2391 Hibernation mode delay time
0 ... 3599 s (factory setting 120).
The hibernation mode delay time starts as soon as the output frequency of
the inverter drops below the hibernation mode start speed p2390. If the
output frequency increases above this threshold during the delay time, the
hibernation mode delay time is interrupted. Otherwise, the motor is switched
off after the delay time has expired (if necessary, after a short boost).
p2392 Hibernation mode restart value (as a %)
Is required if the technology controller is used as the main setpoint.
As soon as the technology controller deviation (r2273) exceeds the hiberna-
tion restart value, the inverter switches to normal operation and the motor
starts up 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
closed-loop controller (r2260).
p2393 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
