When output frequency ≦ sleep frequency and time > detection time, it will go into sleep mode.
When min. output frequency ≦ PID frequency ≦ lower bound of frequency and sleep function
is enabled (output frequency ≦ sleep frequency and time > detection time), frequency will be 0
(in sleep mode). If sleep function is disabled, frequency command = lower bound frequency.
When PID frequency < min. output frequency and sleep function is enabled (output frequency
≦ sleep frequency and time > detection time), output frequency =0 (in sleep mode).
If output frequency ≦ sleep frequency but time < detection time, frequency command = lower
frequency. If sleep function is disabled, output frequency =0.
