Note
Technology controller as main setpoint
To use the technology controller as main setpoint for the cascade control, interconnect the
main setpoint with the technology controller output (p2251 = 0, p2200 =1)
For more information, see the parameter descriptions and function diagram 7036 in the List
Manual.
Additional conditions when the hibernation mode is enabled
In order that the cascade control and hibernation mode functions operate without any
conflict, you must parameterize the cascade control so that the following conditions are
satisfied.
● 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 less than the
overcontrol threshold for the cascade control (p2376).
● It is not permissible that the main drive is in the hibernation mode.
● The actual speed must be higher than the restart speed for the hibernation mode
(p1080 + p2390) * 1.05.
● The value for the activation delay of the cascade control (p2374) must be longer than the
power-up time from the hibernation mode (t
