3) PID Feedback Rate Percentage (Use PID, Pr08-00 ≠ 0 and Pr08-18=1)

When the PID feedback rate reaches the sleep level percentage, the VFD starts to count the sleep

time. The output frequency will also decrease. If the VFD exceeds the preset sleep time, it will go to

sleep mode which is 0 Hz. But if the VFD doesn’t reach the sleep time, it will remain at the lower limit

(if there is a preset of lower limit.). Or it will remain at the lowest output frequency set at Pr01-07 and

wait to reach the sleep time then go to sleep mode (0 Hz).

When PID feedback value reaches the wake up percentage the motor drive will start to count the

wake up delay time. Once reaches the wake up delay time, the motor drives starts the accelerating

time to reach PID frequency command
