BATRY
 Enable battery operation -- BATRY (Function code data = 59)
Turning this terminal command ON cancels the undervoltage protection so that the inverter runs the motor with
battery power under an undervoltage condition.
When BATRY is assigned to any digital input terminal, the inverter trips after recovery from power failure just as
F14 = 1 regardless of F14 setting. When BATRY is ON, the main power down detection is disabled regardless of
H72 setting.
Prerequisites for battery operation
(1) The terminal command BATRY (data = 59) must be assigned to any digital input terminal.
(2) A DC link bus voltage must be supplied from the battery to the main circuit (L1/R-L3/T or L2/S-L3/T) as shown
in Figures A and B given below.
(3) A regulated voltage (sine-wave or DC voltage) must be supplied to the auxiliary power supply (R0-T0).
(4) For 200 V class series / 230V class series 37 kW / 60 HP and above and 400 V class series / 460V 75 kW /
125 HP and above, a regulated voltage (sine-wave) must be supplied to the auxiliary fan power supply (R1-T1) as
shown in Figure B. The fan power supply connector must be configured for battery operation as shown in Figure C.
(5) The BATRY-assigned terminal (data = 59) must be turned ON at the same moment as closing of MC2.
