10-12 is the level for signal loss. Error = (Set point – Feedback value). When the error is
larger than the loss level setting, the feedback signal is considered lost.

When PID output frequency is less than the sleep threshold frequency and exceeds the time
of sleep delay, the inverter will decelerate to 0 and enters PID sleep mode.
¾
When PID output frequency is larger than the Wake up threshold frequency inverter will
enter the PID mode again as shown in the timing diagram below.
