5.8.3 PID Sleep Mode
If an operation continues at a frequency lower than the PID operation conditions, a boost
operation is performed to extend sleep mode by raising the PID Reference, and then the inverter
enters PID sleep mode. In PID sleep mode, the inverter resumes PID operation when the PID
feedback falls below the PID Wakeup level and maintains the condition for the time set at AP1-09
(PID WakeUp1 DT) or AP1-13 (PID WakeUp2DT).
Note
PID Wakeup level may be calculated using the following formula:
PID Wakeup Level = PID-04 (PID Ref Value)–AP1-10 (PID WakeUp1Dev) or, PID-04 (PID Ref Value) - AP1-
14 PID (WakeUp2Dev).
Two sets of configurations are available in PID sleep mode for sleep mode frequency, sleep mode
delay time, wakeup variation, and wakeup delay time. One of the two configurations may be
selected depending on the multi-function input terminal configuration and input conditions.
