p2383

Closed-loop cascade control switch-out sequence / Csc_ctr sw-out seq

Access level: 3
Can be changed: T
Unit group: -
Min:
0
Description: Selection of the response used to stop the motors when the OFF command is sent.
For p2383 = 1:
OFF1 disconnects the external motors from the line in the order 3 - 2 - 1. The time set in p2387 is applied as a delay
time between the disconnection of each motor. The main motor is only switched off if all the external motors have
already been switched off.
In the case of OFF2 and OFF3, the external motors and the main motor are switched off immediately with the OFF
command (same behavior as with p2383 = 0).
Value: 0:
1:
CAUTION
If p2383 = 1 and the OFF1 command is pending, the main motor will not be stopped until all external motors have been
disconnected and time p2387 has elapsed. By switching off the external motors the main motor can be accelerated
again.
p2384

Closed-loop cascade control motor switch-on delay / Csc_ctr t_del_on

Access level: 3
Can be changed: T, U
Unit group: -
Min:
0.000 [s]
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).
p2385 Closed-loop cascade control holding time switch-in speed / Csc_ctr t_hld n_in
Access level: 3
Can be changed: T, U
Unit group: -
Min:
0.000 [s]
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.
p2386 Closed-loop cascade control motor switch-off delay / Csc_ctrl t_del_off
Access level: 3
Can be changed: T, U
Unit group: -
Min:
0.000 [s]
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).
