There are three scenarios for the sleep and wake-up frequency.
1. Frequency Command (PID is not in use, Pr.08-00 = 0. Works only in VF mode)
When the output frequency reaches the sleep level (Pr.08-10), the drive operates in sleep
level and starts to count the sleep delay time (Pr.08-12).
When the Frequency command reaches the wake-up level (Pr.08-11), the drive starts to
count the wake-up delay time (Pr.08-22). When the drive counts exceeding the wake-up
delay time, it starts to catch up to reach the Frequency command value by the acceleration
time.
2. Internal PID Calculation Frequency Command (PID is in use, Pr.08-00 ≠ 0 and Pr.08-18=0.)
When the PID calculation Frequency command reaches the sleep level (Pr.08-10), the drive
starts to count the sleep delay time (Pr.08-12).When the drive counts exceeding the sleep
delay time, the drive is in sleep mode (0 Hz). If the drive does not reach the preset sleep
time, the output frequency remains at the lower frequency limit (if the lower limit is not set to
zero), or it remains at the minimum output frequency set for Pr.01-07 (if the lower limit is set
to zero) and waits until it reaches the sleep delay time before going into sleep mode (0 Hz).
When the PID calculated Frequency command reaches the wake-up frequency, the drive
starts to count the wake-up delay time (Pr.08-22). Once it exceeds the wake-up delay time,
the drive starts to catch up to reach the PID Frequency command value by the acceleration
time.
