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 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 Pr.01-07 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.
