Accumulated
Operation
Time
Displays the cumulative operation time of the
drive. The value for the cumulative operation
time counter can be reset in parameter o4-01.
Use parameter o4-02 to determine if the
operation time should start as soon as the power
is switched on or only while the run command
is present. The maximum number displayed is
99999, after which the value is reset to 0.
No signal output

<1> U1-03 and U4-13 display monitor contents in amp units. When reading the value of these monitors via
MEMOBUS/Modbus, a value of 8192 is equal to 100% of the drive rated output current.
<2> When this value reaches 100%, the maintenance period has been reached for the component in question and the
drive is at risk of faulting out due to component failure. Periodically check the maintenance monitors to avoid
this situation.
<3> MEMOBUS/Modbus communications data is in 10 h units. If data in 1 h units are also required, refer to register
0099H.
