5.3 Description of Function Codes

UPS operation (When BATRY/UPS = ON)
(1) The inverter can run the motor starting from the voltage level specified with H111.
(2) The
RDY (“Inverter ready to run” signal) is forced to go OFF.
(3) The circuit of charging resistor is shorted (73X = ON) after the delay time T1 (0.2 sec) from the timing which
BATRY/UPS terminal being turned on and the DC link bus voltage exceeds UPS operation level (specified
with H111) or above. In addition, after the delay time T2 (max. 0.1 sec.), the UPS operation starts. For T1
specifications, see the table below.
(4) During the UPS operation, the inverter can run the motor.
(5) S-curve acceleration/deceleration becomes invalid.
