(004C)
Cumulative Ope Time
Shows the cumulative operation time of the drive.
Use parameter o4-01 [Elapsed Operating Time Setting] to reset this monitor. Use parameter o4-02
[Elapsed Operating Time Selection] to select the cumulative operation times from:
•
The time from when the drive is energized until it is de-energized.
•
The time at which the Run command is turned ON.
The maximum value that the monitor will show is 99999 . After this value is more than 99999 , the
drive automatically resets it and starts to count from 0 again.
Unit: 1 h
Note:
The MEMOBUS/Modbus communication data is shown in 10 h units. Use register 0099H for
data in 1 h units.
10 V: 99999 h
U4-02
(0075)
Num of Run Commands
Shows how many times that the drive has received a Run command.
Use parameter o4-13 [RUN Command Counter @ Initialize] to reset this monitor. The maximum
value that the monitor will show is 65535 . After this value is more than 65535 , the drive
automatically resets it and starts to count from
0
again.
Unit: 1
10 V: 65535 times

Cooling Fan Ope Time
Shows the cumulative operation time of the cooling fans.
Use parameter o4-03 [Fan Operation Time Setting] to reset this monitor. The maximum value that
the monitor will show is 99999 . After this value is more than 99999 , the drive automatically resets it
and starts to count from 0 again.
Unit: 1 h
Note:
The MEMOBUS/Modbus communication data is shown in 10 h units. Use register 009BH for
data in 1 h units.
