2. Frequency Command Calculation of the Internal PID (Use PID Pr.08-00≠0)
When the PID calculation reaches the sleep frequency, the drive starts to count the sleep
time and the output frequency starts to decrease. If the drive exceeds the preset sleep time, it
goes directly to sleep mode (0 Hz). If the drive does not reach the sleep time, it remains at the
lower limit (if there is a preset of lower limit), or it remains at the lowest output frequency set at
Pr.01-07 and wait to reach the sleep time before it goes into sleep mode (0 Hz).
When the calculated frequency command reaches the wake-up frequency, the drive starts to
count the wake-up delay time. Once it reaches the wake-up delay time, the drive starts the
acceleration time to reach the PID frequency command value.
