p1080 Minimum speed
0 (factory setting) … 19,500 rpm. Lower limit of the motor
speed, independently of the speed target value.
✓ ✓
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 con‐
troller
✓ -
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 converter
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) ex‐
ceeds the hibernation restart value, the converter 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
controller (r2260).
