Cumulative Operation
Time
Drv Elapsed 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.
