User Manual of EM730 Series Inverter Suggestion: F09.28 (sleep action point) is greater than or equal to F09.30 (wake-up action point) during the positive action, and less than or equal to F09.30 (wake-up action point) during the negative action. 248 constant pressure control) restart after the stop or sleep), or the output frequency of the inverter reaches the lower limit, causing the failure to continue to decelerate (due to the lower frequency limit or lower output limit of the inverter), and these conditions have been met and maintained to the sleep delay time (F09.29), the sleep status will be enabled. ★： The PID continues the output during the delay period.
The output depends on the function code after the delay period. Sleep status Judgment of the wake-up conditions: If the |Feedback| is less than or equal to the value of the wake-up action point (F09.30), and this has been maintained for the wake-up delay time (F09.31), the sleep status will be disabled. ★: The output depends on the function code during the delay period; and the PID can continue normal output after the delay period. Negative action (e.g. constant temperature control) Normal work Judgment of the sleep conditions: If the |Feedback| is less than the sleep action point (F09.28) (necessary condition:
the feedback pressure must be lower than or equal to the set pressure during restart after the stop or sleep), or the output frequency of the inverter reaches the lower limit, causing the failure to continue to decelerate (due to the lower frequency limit or lower output limit of the inverter), and these conditions have been met and maintained to the sleep delay time (F09.29), the sleep status will be enabled. ★： The PID continues the output during the delay period. The output depends on the function code after the delay period. Sleep status Judgment of the wake-up conditions:
If the |Feedback| is greater than or equal to the value of the wake-up action point (F09.30), and this has been maintained for the wake-up delay time (F09.31), the sleep status will be disabled. ★: The output depends on the function code during the delay period; and the PID can continue normal output after the delay period.
