2-word data
Readable
- Explanation
This variable can be used to monitor the accumulated running time of the inverter. The data monitored
with this variable corresponds to the data monitored by the cumulative operation RUN time monitoring
function (d016). This variable is read-only.
- Sample program: Program to output a one-second pulse signal indicating the running time of the
inverter to a contact output every hour
：
LOOP UL(01)= UL(00) : Set the previous data in variable "UL
(01)".
UL(00)= RUN-Time : Fetch the running-time data.
if UL(00) = UL(01) then LBL1
Y(00)= 1 : Turn Y (00) on.
delay off Y(00) TD(2) 100 : Turn Y (00) off after 1 second elapses.
LBL1 goto LOOP

2-word data
Readable
- Explanation
This variable can be used to monitor the accumulated power-on time of the inverter. The data
monitored with this variable corresponds to the data monitored by the cumulative power-on time
monitoring function (d017). This variable is read-only.
- Sample program: Program to convert the power-on time into a number of days and output the
converted data as word data to Y (00) to Y (05)
UL(00)= ON-Time : Fetch the power-on time data.
UL(00)= UL(00) / 24 : Convert the data into a number of days.
Yw= UL(00) and 31 : Output the data to Yw.
