The reference step will always be automatically added to the reference value when the
corresponding auxiliary drive is started. With the reference steps, e.g. the pressure
loss in the piping caused by the increased flow can be compensated. See Figure 8-55.
1016 Sleep frequency 57 (P1.1.15)
The frequency converter is automatically stopped if the frequency of the drive falls
below the Sleep level defined with this parameter for a time greater than that
determined by ID1017. During the Stop state, the PID controller is operating switching
the frequency converter back to the Run state when the actual value signal either falls
below or exceeds (ID1019) the Wake-up level determined by ID1018. See Figure 8-56.
