When the calculated frequency command reaches the wake-up frequency, the VFD will start to
count the wake-up delay time. Once reaching the wake-up delay time, the VFD will start the
acceleration time to reach the PID frequency command.
3) PID Feedback Rate Percentage ( Use PID, Pr08-00
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 percentagethe 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
