Description: Additional delay time for the connection of external motors on the line voltage (staging) after the system deviation of
the technology controller has exceeded the threshold value p2373 and the motor has reached the maximum speed.
Dependency: Refer to: p2373
Note: If the deviation at the technology controller input exceeds the overcontrol threshold p2376, the delay time is
bypassed.
Description: Additional delay time for the disconnection of external motors from the line (de-staging) after the system deviation
of the technology controller has exceeded the threshold p2373 and the motor has reached the minimum speed
p1080.
Dependency: Refer to: p2373, p2376
Note: If the deviation at the technology controller input exceeds the overcontrol threshold -p2376, the delay time is
bypassed.
Description: Threshold value for the non-delayed switching-in (staging) or switching-off (de-staging) of 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 staging is executed immediately.
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 de-staging is executed immediately.
Description: Lockout time during which, following the connection or disconnection of an external motor, no further motors are
connected or disconnected by means of staging/de-staging. This avoids duplicate switching operations.
