7.9.2 Sleep / Wake Function

This function is used to achieve the maximum extent of energy-saving according
to the type of loads in actual applications, for example hydraulic system with
small leakage or accumulator. This function runs according to the PID control
mode, as FcP 5020 ASF active is, this will be assigned to the p/Q PID controller
in ASF, and the basic PID controller of EFC will be deactivated.
Code Name
E5.15 Sleep level
E5.16 Sleep delay
E5.17 Sleep boost time
E5.18 Sleep boost amplitude
E5.19 Wake up level
E5.20 Wake up delay
Tab. 7-15: Parameter list of sleep / wake function
The frequency converter may go into the sleep mode when all the conditions be-
low are met:
[PID feedback] > Pressure command value x [E5.19] ''Wake up level''
●
[PID output] < [E5.15] ''Sleep level''
●
[Duration] t ≥ [E5.16] ''Sleep delay''
●
PID feedback means pressure feedback in FcP 5020. The wake up
●
level or sleep boost amplitude has unit of percentage. This per-
centage is referred to pressure command value in bar.
PID output means the speed output from p/Q controller in FcP
●
5020, without speed ramp from E0.26 / E0.27. This value has the
same unit as sleep level, i.e. Hz.
