Note 2) Pre-PID
The Pre PID function is activated in Function code A82 (Pre PID Frequency). When the run signal comes,
the inverter operates in the form of Open loop. If the output frequency reaches the Pre PID Frequency, it
operates in Closed loop (PID control).

Note 3) Sleep and Wake up
In Function code A83 (Sleep Frequency), the sleep function is activated. When the output frequency falls
below the Sleep Frequency(A83) for the Sleep Delay Time(A84), operates the sleep mode. If output
frequency rises above the Sleep Frequency , the sleep delay time is reset. The inverter has stopped the
motor In sleep mode. When the PID output frequency rises above the Wake up Frequency(A85) for the
Sleep Delay Time(A84), the inverter restart the motor.
