detection time), frequency will be 0 (in sleep mode). If output frequency < sleep frequency and
time < detection time, the 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.
