The time duration of T1 changes depending on the voltage and capacity. Refer to the description of

Precautions
(1) The battery power supply must be connected before BATRY signal is turned ON. Alternatively
connect the battery power supply at the same time as turning ON BATRY signal.
(2) As shown above, inverter operation is possible within the battery operation allowable zone.
There must be a delay of the "T1 + T2" period from when the BATRY , MC, and battery power
supply are turned ON. After that the inverter becomes ready to run.
(3) The BATRY should not be turned ON as long as the voltage level is higher than the specified
undervoltage level (that is, before the LV appears after a power failure). Doing so blocks 73X to
go OFF.
(4) During battery operation, avoid operation with a driving load and run the elevator with a
balanced or regenerative load. Low battery voltage cannot generate sufficient torque and it
causes the motor to stall.
(5) These precautions are given for an inverter operation with an extremely low voltage that
prevents normal operation. For battery operation with a high voltage (such as 600 V for 400 V
class series inverter), do not use the BATRY but run the inverter in a normal manner at a low
speed and be careful with the battery capacity,
(6) In the case of normal operation, turn off BATRY . If the main power supply is turned ON with
BATRY being ON, it could damage the inverter rectifier diode due to the inrush current by 73X
ON state.
