p2375 Closed-loop cascade control switch-out delay / Csc_ctrl t_out_del
Access level: 3 Calculated: - Data type: Unsigned16
Can be changed: T, U Scaling: - Dynamic index: -
Unit group: - Unit selection: - Function diagram: -
Min:
0 [s]
Max:
650 [s]
Factory setting:
30 [s]
Description: Additional delay time for the disconnection of external motors from the line after the system deviation of the technology
controller has exceeded the threshold p2373 and the motor has reached the minimum speed p1080.
Dependency: See also: p2373, p2376
Note
If the deviation at the technology controller input exceeds the overcontrol threshold -p2376, the delay time is bypassed.
p2376 Closed-loop cascade control overcontrol threshold / Csc_ctr ovctr_thr
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: PERCENT Dynamic index: -
Unit group: 9_1 Unit selection: p0595 Function diagram: -
Min:
0.0 [%]
Max:
200.0 [%]
Factory setting:
25.0 [%]
Description: Threshold value for instantaneous switching-in or switching-out external motors.
Note
If the maximum speed is reached and the deviation at the technology controller input exceeds the overcontrol threshold
p2376 at the same time, the delay time p2374 is bypassed and the motor is immediately switched-in (connected).
If the minimum speed is reached and the deviation at the technology controller input exceeds the overcontrol threshold
-p2376 at the same time, the delay time p2375 is bypassed and the motor is immediately switched-out (disconnected).
p2377 Closed-loop cascade control interlocking time / Csc_ctrl t_interl
Access level: 3 Calculated: - Data type: Unsigned16
Can be changed: T, U Scaling: - Dynamic index: -
Unit group: - Unit selection: - Function diagram: -
Min:
0 [s]
Max:
650 [s]
Factory setting:
0 [s]
Description: Interlocking time during which, following the connection or disconnection of an external motor, no further motors are
connected or disconnected using the closed-loop cascade control. This avoids duplicate switching operations.
p2378 Closed-loop cascade control switch-in/switch-out speed / Csc_ctrl n_in/out
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: T Scaling: - Dynamic index: -
Unit group: - Unit selection: - Function diagram: -
Min:
0.0 [%]
Max:
100.0 [%]
Factory setting:
50.0 [%]
Description: Sets the speed for the main drive, which is approached directly after an external motor has been connected or
disconnected.
The parameter value refers to the maximum speed (p1082).
