Precautions
(1) The battery power supply must be connected before or at the same moment as turning ON of BATRY .
(2) As shown in the timing diagram above, battery operation is possible within the battery operation-enabled zone.
There is a delay of "T1 + T2" after the BATRY , MC2, and battery power supply are turned ON.
(3) The BATRY must not be turned ON when the voltage level is higher than the specified undervoltage level (that is,
before the lu appears after a power failure). Turning the BATRY ON causes the bypass circuit (73X) of the charging
resistor to stick to ON (closed).
(4) During battery operation, driving with a heavy load must be avoided and the motor must run with no load or braking
load condition. Low battery voltage cannot generate sufficient torque, causing the motor to stall.
(5) The battery operation must be performed at a low speed. Be careful with the battery capacity.
When a high voltage (e.g., 300 VDC for 200 V class series / 230 V class series for USA of inverters or 600 VDC for
400 V ones / 460 V ones for USA) is applied, not battery operation but normal operation must be performed.
(6) In normal operation, the BATRY must be OFF. Turning the main power supply ON with the BATRY being ON could
damage the rectifier diode because the 73X is ON.

Count the run time of commercial power-drive motors 1 to 2 -- CRUN-M1 , CRUN-M2 (Function code data =
72, 73) These four terminal commands enable the inverter to count the cumulative run time of motors 1, 2 even
when they are driven by commercial power (not by the inverter). When the CRUN-M1 , CRUN-M2 is ON, the inverter
counts the run time that the motor 1, 2 is driven by commercial power.

Select droop control
–
DROOP ( Function code data = 76)
This terminal command DROOP toggles droop control on and off.

Refer to H28.

ON Enable
OFF Disable

Cancel PG alarm-- PG-CCL (Function code data = 77)
When this terminal command is ON, the PG signal loss alarm is ignored. Use this terminal command when
switching PG wires for switching motors, for example, to prevent it from being detected as PG wire break.

Run forward -- FWD (Function code data = 98)
Turning this terminal command ON runs the motor in the forward direction; turning it OFF decelerates it to stop.
This terminal command can be assigned to the same setting as E01 thru E07 only by parameter E98.

Run reverse -- REV (Function code data = 99)
Turning this terminal command ON runs the motor in the reverse direction; turning it OFF decelerates it to stop.
This terminal command can be assigned to the same setting as E01 thru E07 only by parameter E99.
