Operation of the self power management function
• This function controls the magnetic contactor (MC) on the input side using the output relay to reduce the standby power
during inverter stop. With the terminals R1/L11 and S1/L21 (refer to
to
page
73), the main circuit power supply and control circuit power supply are separated, and the MC for main circuit power
supply is controlled by the electronic bypass MC1 signal.
• Set Pr.248 Self power management selection = "1 or 2", Pr.30 Regenerative function selection ≠ "20, 21, 120, or 121"
(other than DC feeding mode 2), and Pr.190 to Pr.196 (Output terminal function selection) = "17 (positive logic)" to
assign the Electronic bypass MC1 (MC1) signal to an output terminal.
• After the inverter is stopped and the time set in Pr.11 DC injection brake operation time and Pr.254 Main circuit power
OFF waiting time have passed, turning OFF the MC1 signal releases the MC on the input side (main circuit power supply
OFF). Set Pr.254 to prevent frequent MC operation.
• Turning ON the start signal turns ON the MC1 signal and closes the MC on the input side (main circuit power supply ON).
After the time set in Pr.137 Start waiting time has passed, the inverter starts. Set time slightly longer (about 0.3 to 0.5
second) than the time period from the MC1-ON to the actual pick-up operation of the MC is turned ON in Pr.137.
