◆ o4: Maintenance Monitor Settings
■ o4-01: Cumulative Operation Time Setting
Parameter o4-01 sets the cumulative operation time and allows the user to set the starting value of the accumulated
operation time displayed in monitor U4-01.
Note: The value in o4-01 is set in 10 h units. For example, a setting of 30 will set the cumulative operation time counter to 300 h. 300 h
will also be displayed in monitor U4-01.
■ o4-02: Cumulative Operation Time Selection
Selects the conditions for what is to be considered “accumulated operation time.” Accumulated operation time is
displayed in U4-01.
Setting 0: Power On Time
The drive logs the time it is connected to a power supply, no matter if the motor is running or not.
Setting 1: Run Time
The drive logs the time that the output is active, i.e., whenever a Run command is active (even if the motor is not
rotating) or a voltage is output.

o4-03: Cooling Fan Operation Time Setting
Sets the value of the cooling fan operation time counter displayed in monitor U4-03. Parameter o4-03 also sets the base
value used for the cooling fan maintenance value displayed in U4-04. Be sure to reset this parameter back to 0 if the
cooling fan is replaced.
Note: 1. The value in o4-03 is set in 10 h units. For example, a setting of 30 will set the cooling fan operation time counter to 300 h. “300” will
be displayed in monitor U4-03.
2. The actual maintenance time depends on the environment the drive is used in.
■ o4-05: Capacitor Maintenance Setting
Sets value of the maintenance monitor for the DC bus capacitors displayed in U4-05 as a percentage of the total expected
performance life. This value should be reset to 0 when the DC bus capacitors have been replaced.
Note: The actual maintenance time will depend on the environment the drive is used in.
■ o4-07: DC Bus Pre-charge Relay Maintenance Setting
Sets the value of the softcharge bypass relay maintenance time displayed in U4-06 as a percentage of the total expected
performance life. This value should be reset to 0 when the relay has been replaced.
Note: The maintenance actual time depends on the environment the drive is used in.
