Further information
Interaction with the "Hibernation mode" function
In order that the "Cascade control" and "Hibernation mode" functions do not influence each
other, you must make the following settings in the cascade control:
● p2392 < p2373
The restart value of the hibernation mode p2392 must be lower than the activation threshold
for the cascade control p2373.
● p2373 < p2376
The activation threshold for the cascade control p2373 must be lower than the overload
threshold for the cascade control p2376.
● It is not permissible for the main drive to be in the hibernation mode.
● The actual speed must be higher than the restart speed for hibernation mode
(p1080 + p2390) × 1.05.
● The value for the activation delay of the cascade control p2374 must be higher than the
ramp-up time t
y
from hibernation mode.
t
y
= (p1080 + p2390) × 1.05 × p1120 × p1139/p1082
