6.1.14.4 Group 3.13.4: FeedForward
Feedforward usually needs accurate process models, but in some simple cases a gain + offset
type of feedforward is enough. The feedforward part does not use any feedback measurements
of the actual controlled process value (water level in the example on page 144). Vacon feedfor-
ward control uses other measurements which are indirectly affecting the controlled process
value.
6.1.14.5 Group 3.13.5: Sleep Function
This function will put the drive into sleep mode if the frequency stays below the sleep limit for
a longer time than that set with the Sleep Delay.

Code Parameter Min Max Unit Default ID Description
P3.13.5.1 SP 1 Sleep Freq 0.00 320.00 Hz 0.00 1016
Drive goes to sleep mode
when the output frequency
stays below this limit for a
time greater than that
defined by parameter
Sleep
delay
.
P3.13.5.2 SP 1 Sleep Delay 0 3000 s 0 1017
The minimum amount of
time the frequency has to
remain below the Sleep level
before the drive is stopped.
P3.13.5.3 SP 1 WakeUpLevel Varies 0.00 1018
Defines the level for the PID
feedback value wake-up
supervision. Uses selected
process units.

Select if wake up level should
work as an absolute level or
as an offset below the actual
