Fig. 89: Sleep, no demand detected
A. The output frequency of the drive
B. The PID feedback value
C. The PID setpoint value
D. SNDD Frequency Hysteresis (P3.13.10.3)
E. SNDD Error Hysteresis (P3.13.10.2)
The hysteresis area around the PID
setpoint value.
F. SNDD Actual Add (P3.13.10.5)
G. SNDD Supervision Time (P3.13.10.4)
H. The PID feedback value and the output
frequency of the drive are in the
hysteresis areas for the set time (SNDD
Supervision Time). A bias value (SNDD
Actual Add) is added to the PID feedback
value.
I. SP1 Sleep Delay Time (P3.13.5.2)
J. The drive goes to the Sleep mode.
K. Process Unit (P3.13.1.4)
P3.13.10.1 SLEEP NO DEMAND DETECTION ENABLE (ID 1649)
Use this parameter to activate the Sleep No Demand Detection (SNDD) function.
P3.13.10.2 SNDD ERROR HYSTERESIS (ID 1658)
Use this parameter to set the hysteresis for the error value of the PID controller.
P3.13.10.3 SNDD FREQUENCY HYSTERESIS (ID 1663)
Use this parameter to set the hysteresis for the output frequency of the drive.
P3.13.10.4 SNDD SUPERVISION TIME (ID 1668)
Use this parameter to set the time that the output frequency of the drive and the error value
of the PID controller must stay in the hysteresis areas before the SNDD function becomes
active.
P3.13.10.5 SNDD ACTUAL ADD (ID 1669)
Use this parameter to set the value that is added to the actual value of the PID feedback for a
short time when the SNDD function is active.
