PID Control Bit

Settings
 Bit0, When Pr08-21 = 1, PID reverse running is enable..
 Bit0 = 0, if the PID calculated value is positive, it will be forward running. If the PID calculated value
is negative, it will be reverse running.
There are three scenarios for sleep and wake-up frequency.
1) Frequency Command (PID is not in use, Pr08-=00
When the output frequency ≦ the sleep frequency, and the VFD reaches the preset sleep time,
then the VFD will be at the sleep mode.
When the frequency command reaches the wake-up frequency, the VFD will start to count the
wake-up delay time. Then when the VFD reaches the wake-up delay time, the VFD will begin
acceleration time to reach the frequency command.

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.
0.00~600.00 sec.
Bit0 =1, PID reverse running must follow the setting of Pr00-23
Bit0 = 0, PID reverse running follows PID's calculated value
