When this terminal command is turned on, the undervoltage protection is invalidated. In that case, the motor can
be operated by the inverter with undervoltage status by the battery power.
In addition, the main power down detection also becomes invalid regardless of H72 setting.
Prerequisite of battery operation
(1) Terminal function BATRY/UPS (data = 59) can be assigned to any digital input terminal.
(2) As shown in Figure 5.3-7 and Figure 5.3-8, DC link bus voltage is supplied from the battery to the
main circuit (L1/R-L3/T or L2/S-L3/T).
(3) The specified voltage (sinusoidal waveform or DC voltage) is input to auxiliary power terminal
(R0-T0).
(4) In case of FRN0203E2


or above, input the specified power supply (sinusoidal waveform) to
the fan power supply auxiliary input (R1-T1) as shown in Figure 5.3-9, and change the fan power
supply switching connector as shown in Figure 5.3-10 in order to execute the battery operation.
(5) The terminal that BATRY/UPS (data = 59) is assigned has to be turned on simultaneously with the
MC2.
