5.3 Description of Function Codes
5-114
Battery operation (When BATRY/UPS = ON)
(1) Undervoltage protection function (lu )becomes non-operating status.
(2) The inverter can operate the motor even under the undervoltage condition.
(3) Operation ready complete
RDY signal is turned off.
(4) The circuit of charging resistor is shorted (73X = ON) after the delay time T1 from the BATRY/UPS terminal
being turned on. In addition, after the delay time T2 (max. 0.1 sec.), the battery operation starts. For T1
specifications, see Table 5.3-10 on the next page.

the battery, and turning on of the short circuit 73X for the charging
resistor
(5) S-curve acceleration/deceleration becomes invalid.
(6) The operable speed during the battery operation is calculated by using the following expression.
