About battery operation (when BATRY is ON)
(1) The undervoltage protective function ( lu ) is deactivated.
(2) The inverter can run the motor even under an undervoltage condition.
(3) The RDY ("Inverter ready to run") output signal is forcedly turned OFF.
(4) The bypass circuit of the charging resistor comes to be closed (73X ON) after a delay of time T1 from when the
BATRY is turned ON. Further, after a delay of time T2 (a maximum of 0.1 second), the battery operation starts. For
the specifications of T1, see the table below.

After the control power supply goes OFF, the
battery power and control power are turned ON. 100 ms 500 ms
The control power remains ON or after a
momentary power failure happens. 205 ms
(5) The S-curve acceleration/deceleration is disabled.
(6) The battery operation speed can be calculated by the following formula.
