2.2 List of parameters
Description: Delay time once the switch-in conditions have been met until the external motor is switched on.
The activation of the corresponding status bit (r2379) for controlling the contactors or the motor starter is delayed by
this time, while the main motor speed already decreases down to the switch-in speed (p2378).
Description: Time during which the switch-in speed (see p2378) of the main motor is maintained after an external motor has been
switched-in and the main motor has been decelerated to the switch-in speed.
Description: Delay time once the switch-out 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 switch-out speed (p2378).
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.
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.
