Requirements for battery operation
(1) BATRY (data = 63) must be assigned to any digital input terminal.
(2) A DC voltage (or AC voltage in case of using UPS) must be supplied to the main circuit (R-T or
S-T). The necessary DC voltage depends on the operation speed and load.
(3) Only in the case of using batteries, control board has to be supplied additionally. Control board
supply terminals depend on inverter capacity:
- FRN0032LM2A-4_ or below: +24V/-24V
- FRN0039LM2A-4_ or above: R0/T0
For additional information about external power supply terminals, refer to Instruction manual.
(4) BATRY must be turned ON.

Specifications
(1) The under voltage protection ( LU ) is disabled.
(2) The inverter can run the elevator even in the under voltage condition.
(3) The
RDY ("Inverter ready to run" signal) is forced to go OFF.
(4) The bypass contact of the charging circuit (73X ON) is delayed a defined time (T1) specified in
table 1 from BATRY ON. After that delay time it takes 0.1s (T2) as the start waiting time.
Situation Waiting time (T1)
After control power supply goes OFF,
battery power supply and control
power supply turns ON
200ms
The control power supply remains ON
or after momentary power failure
happens.

(5) During the battery operation, if manual speed (middle) is selected (if the L11 to L18 are default
setting, the terminal conditions are SS1 =ON, SS2 =OFF, SS4 =OFF and SS8 =OFF), inverter runs
the elevator at the speed specified by C03. Even if the analog speed command is selected and
the manual speed (middle) is selected via general-purpose digital input terminals, inverter runs
the elevator at the speed specified by C03 also.
When the multistep speed other than the manual speed (middle) is selected, the inverter runs the
elevator at the speed specified by the corresponding function code.
(6) In battery operation, the acceleration/deceleration time specified by E17 is selected. The S-curve
is disabled in acceleration or deceleration.
When the inverter runs by analog speed command in battery operation, E10 for acceleration
time and E11 for deceleration time are selected.
(7) Decide the battery operation speed by calculating with the following formula based on the
battery voltage. The battery voltage should be above 48 VDC in case of 400 V inverter.
