3. PID Feedback Rate Percentage ( Use PID, Pr.08-00 ≠ 0 and Pr.08-18=1)
When the PID feedback rate reaches the sleep level percentage, the drive starts to count the
sleep time. The output frequency also decreases. If the drive exceeds the preset sleep time, it
goes to sleep mode (0 Hz). If the drive does not reach the sleep time, it remains at the lower limit
(if there is a preset of lower limit.), or it remains at the lowest output frequency set for Pr.01-07 and
waits to reach the sleep time before going into sleep mode (0 Hz).
When the PID feedback value reaches the wake-up percentage, the drive starts to count the
wake-up delay time. Once it reaches the wake-up delay time, the drive starts the acceleration time
to reach the PID frequency command value.

Case 01: If feedback >12kg, frequency decrease.
Case 02: If feedback < 6kg, frequency increase.
