U4: Maintenance Monitors
Use U4 parameters to display drive maintenance information.
U4-01
Cumulative 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.
