General converter behavior when in the PROFIenergy energy-saving mode
● When the PROFIenergy energy-saving mode is active, the converter issues alarm
A08800.
● When the PROFIenergy energy-saving mode is active, the converter does not send any
diagnostic alarms.
● If the bus connection to the control system is interrupted while the converter is in the
energy-saving mode, the converter exits the energy-saving mode and resumes normal
operation ("ready_to_operate").
● The converter changes into normal operation if the control system goes into the stop
condition while the converter is in the energy-saving mode.
Transition into the energy-saving mode from the PROFIdrive operating state (S4)
If you set p5611.2 = 1, you enable transition to the energy-saving mode from the PROFIdrive
operating state (S4)
To do so, you must set one of the following settings:
● p5611.1 = 1: With the transition to the energy-saving mode, the converter issues an
OFF1 command and enters the start-inhibit state (S1).
● p5611.1 = 0: You can use p5614 to interconnect a signal source that switches the
converter off and places it in the start-inhibit state (S1).
If the control sends the command "End_Pause" or "Start_Pause" with a pause time of 0, the
converter continues to run automatically – if the enables are still set.
Inhibit PROFIenergy and idle time
Inhibit PROFIenergy
If you set p5611.0 = 1, you inhibit the response of the converter to PROFIenergy control
commands. In this case, the converter ignores the PROFIenergy control commands.
● Minimum pause time: p5602
– When the pause time, which is sent using command "Start_Pause", is equal to or
greater than the value in p5602[1], then the converter goes into the energy-saving
mode.
– If the pause time is less than p5602[1], the converter ignores the command.
● Maximum duration: p5606
