p2386 Staging motor OFF delay / Staging t_del_OFF
Access level: 3
Can be changed: U, T
Units group: -
Min
0.000 [s]
Description: Delay time once the de-staging conditions have been met until the external motor is switched off.
The resetting of the corresponding status bit (r2379) for controlling the contactors or the motor starter is delayed by
this time, while the main motor ramps up to the staging speed (p2378).
p2387 De-staging speed hold time / Destag t_hold
Access level: 3
Can be changed: U, T
Units group: -
Min
0.000 [s]
Description: Time during which the destaging speed (see p2378) of the main motor is maintained after an external motor has
been disconnected and the main motor has been accelerated to the de-staging speed.
p2390[0...n] Hibernation starting speed / Hib n_Start
Access level: 3
Can be changed: U, T
Units group: 3_1
Min
0.000 [rpm]
Description: Sets the start speed for the hibernation 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 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 powered
down (hibernation active). The drive is automatically powered up again as soon as the speed setpoint exceeds the
restart threshold.
Note: The hibernation start speed is set to 4 % of the nominal speed when commissioning is completed.
p2391[0...n] Hibernation delay time / Hib t_del
Access level: 3
Can be changed: U, T
Units group: -
Min
0 [s]
Description: Sets the delay time for the "Hibernation" function.
To ensure that the drive can be shut down (pulse inhibit), a restart condition must not occur during this time.
Dependency: Refer to: p2390, p2392, p2393
