Description
Minimum speed
0 (factory setting) ... 19500 rpm. Lower limit of the motor speed
is independent of the speed setpoint.
Block negative direction
Parameter to block the negative direction
Technology controller enable
0: Technology controller deactivated (factory setting),
1: Technology controller activated
Technology controller mode
0: Technology controller as main setpoint (factory setting),
1: Technology controller as supplementary setpoint
Technology controller minimum limiting
Parameter for the minimum limiting of the technology controller
Hibernation mode
0: Hibernation mode inhibited (factory setting)
1: Hibernation mode enabled
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
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 neces-
sary, after a short boost).
Hibernation mode restart value (as a %)
Is required if the technology controller is used as the main set-
point.
As soon as the technology controller deviation (r2273) exceeds
the hibernation 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 control-
ler (r2260).
