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.
