o2-09 Initialization Specification Selection
Parameter o2-09 should always be set to “1: American Spec.” (Do not set.) This parameter does not normally require
adjustment. Possible damage to equipment or injury may occur if this setting is changed from “1: American Spec.” o2-09 is a
macro parameter that can change the default values of terminal I/O and many other parameters in the drive. Consult the
Yaskawa factory for details.
o2-10 Cumulative Cooling Fan Operation Time Setting
Setting Range: 0 to 65535 Hours
Factory Default: 0 Hours
The elapsed time of heatsink cooling fan operation is tracked by the U1-40 monitor. Much like the o2-07 parameter can be
used to adjust or reset the Drive operation elapsed timer, parameter o2-10 can be used to adjust the time displayed by the
U1-40 monitor in the event of fan replacement.
o2-12 Fault Trace / Fault History Clear Function
The operator can clear the Fault Trace (U2) and Fault History logs by setting o2-12= “1: Enabled”. Clearing the Fault Trace
and Fault History logs erases all the information.
o2-14 kWh User Monitor Initialization
The kWh monitors (U1-29 and U1-30) track the power usage of the Drive and are not reset by powering down the Drive. To
reset the monitors back to zero, set o2-14= “1: Clear all”.
