(A) Application parameters
Operation of the self power management function
• This is a function to control the input side magnetic contactor (MC) with an output relay to reduce standby power. Use
separate power supplies for the main circuit and the control circuit by using terminals R1/L11 or S1/L21 (refer to
and 24 V external power supply input (refer to
MC1 signal of the inverter.
• Set Pr.248 Self power management selection = "1 or 2", and Pr.190 to Pr.195 (Output terminal function selection) =
"17 (positive logic)" to assign the control signal for main circuit power supply MC (Y17 signal) to an output terminal. (Set
Pr.248 in accordance with the Pr.248 setting of the inverter.)
• The Y17 signal turns ON while the self power management function is enabled.
• When the protective function of the converter unit is activated, the Y17 signal immediately turns OFF according to the
Pr.248 setting.
When Pr.248 = "1", the Y17 signal turns OFF whenever a protective function is activated.
When Pr.248 = "2", the Y17 signal turns OFF only when a protective function is activated by a fault originating in the
converter unit circuit or a connection fault (refer to the table below). (For the fault details, refer to
If the protective function of the slave is activated, the Y17 signal turns OFF regardless of the fault contents.

NOTE
• Repeated operation of the magnetic contactor due to frequent start and stop or activation of the protective function may
shorten the inverter and the converter unit life.
• Changing the terminal assignment using Pr.190 to Pr.195 (Output terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.
Selection between resetting or not resetting during power supply to
main circuit (Pr.30 = "100")
• Converter reset is not performed if Pr.30 Reset selection during power supply to main circuit = "100", and supplying
power to the main circuit (R/L1, S/L2, T/L3 input) is started when power is supplied only to the control circuit (R1/L11, S1/
L12 input, or 24 V external power supply input).
NOTE
• When supplying power to the main circuit is started when power is supplied only to the control circuit, there is a slight waiting
time before starting.
• When supplying power to the main circuit is started while the protective function of the converter unit is activated, converter
reset is performed even when "not resetting after power-ON" is selected.
