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.
Example 01: PID negative feedback
 Pr. 08-10 must > Pr. 08-11
30kg is the reference

 Set the parameter:
Pr. 03-00 = 5 (AVI is PID feedback)
Pr. 08-00 = 1 (PID negative feedback: AVI
simulation input function select)
Pr. 08-10 = 40% (Sleep reference:
Pr. 08-11 = 20% (Wake-up reference:
Case 01: If feedback >12kg, frequency decreases.
Case 02: If feedback <6kg, frequency increases.
12kg = 40%*30kg)
6kg = 20%*30kg)
