Closed-loop cascade control holding time switch-out speed / CscCtr t_hld n_out
Access level: 3
Can be changed: T, U
Unit group: -
Min:
0.000 [s]
Description:
Time during which the switch-out speed (see p2378) of the main motor is maintained after an external motor has been
switched-out and the main motor has been accelerated to the switch-out speed.
p2390[0...n]
Speed start of hibernation mode / Hib mode n_start
Access level: 3
Can be changed: T, U
Unit group: 3_1
Min:
0.000 [rpm]
Description:
Sets the speed for the start of the "hibernation mode" function.
The total speed of this activation threshold is the sum of the minimum speed p1080 and p2390.
If the speed setpoint undershoots this start speed, the delay time in p2391 is started. If the restart threshold is no longer
reached before the delay time expires, the hibernation mode boost speed p2395 is impressed for the time period
p2394 and then the motor is brought to a standstill via the down ramp of the setpoint channel. The drive is switched
off (hibernation mode active). The drive is automatically switched on again as soon as the speed setpoint exceeds the
restart threshold.
Note
The speed at which the hibernation mode is started is set to 4 % of the nominal speed when commissioning is
completed.
p2391[0...n]
Hibernation mode delay time / Hib mode t_delay
Access level: 3
Can be changed: T, U
Unit group: -
Min:
0 [s]
Description:
Sets the delay time for the "hibernation mode" function.
To ensure that the drive can be shut down (pulse inhibit), a restart condition must not occur during this time.

p2392
Hibernation mode restart value with technology controller / Hib start w/ tec
Access level: 3
Can be changed: T, U
Unit group: 9_1
Min:
0.000 [%]
Description:
Sets the motor restart time with the "Hibernation mode" function.
If the hibernation mode function is active, the technology controller continues to operate and supplies a speed setpoint
to the setpoint channel. Since the drive is deactivated, there is no system deviation at the input of the technology
controller. As soon as this exceeds the restart value p2392, the drive is automatically switched on and the speed is
controlled to 1.05 * (p1080 + p2390) via the up ramp of the setpoint channel.
Note
The restart value is set to 5 % when commissioning is completed.
