2) Frequency Command Calculation of the Internal PID
When the PID calculation reaches the sleep frequency, the VFD will start to count the sleep
time and the output frequency will start to decrease. If the VFD exceeds the preset sleep time, it
will directly 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 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).
