YASKAWA TOEPYAIGA8002B GA800 Drive Programming
V/f CL-V/f OLV CLV AOLV
Shows the cumulative operation time when the first to fourth most recent faults occurred.
Unit: 1 h
Note:
The drive saves the U3-11 to U3-14 [ElapsedTime@1st to 4thFault] the cumulative operation
time to two types of registers at the same time for the MEMOBUS/Modbus communications.
V/f CL-V/f OLV CLV AOLV
Shows the cumulative operation time when the fifth to tenth most recent faults occurred.
Unit: 1 h
V/f CL-V/f OLV CLV AOLV
Shows the cumulative operation time of the drive.
Use parameter o4-01 [Elapsed Operating Time Setting] to reset this monitor. Use parameter o4-02
[Elapsed Operating Time Selection] to select the cumulative operation times from:
• The time from when the drive is energized until it is de-energized.
• The time at which the Run command is turned ON.
The maximum value that the monitor will show is 99999. After this value is more than 99999, the
drive automatically resets it and starts to count from 0 again.
Unit: 1 h
Note:
The MEMOBUS/Modbus communication data is shown in 10 h units. Use register 0099H for
data in 1 h units.
V/f CL-V/f OLV CLV AOLV
Shows how many times that the drive has received a Run command.
Use parameter o4-13 [RUN Command Counter @ Initialize] to reset this monitor. The maximum
value that the monitor will show is 65535. After this value is more than 65535, the drive
automatically resets it and starts to count from 0 again.
Unit: 1
V/f CL-V/f OLV CLV AOLV
Shows the cumulative operation time of the cooling fans.
Use parameter o4-03 [Fan Operation Time Setting] to reset this monitor. The maximum value that
the monitor will show is 99999. After this value is more than 99999, the drive automatically resets it
and starts to count from 0 again.
Unit: 1 h
Note:
The MEMOBUS/Modbus communication data is shown in 10 h units. Use register 009BH for
data in 1 h units.
V/f CL-V/f OLV CLV AOLV
Shows the cumulative operation time of the cooling fans as a percentage of the replacement life of
the cooling fans.
Use parameter o4-03 [Fan Operation Time Setting] to reset this monitor.
Unit: 1%
Note:
Replace the cooling fans when this monitor is 90%.
V/f CL-V/f OLV CLV AOLV
Shows the operation time of the electrolytic capacitors for the main circuit and control circuit as a
percentage of the replacement life of the electrolytic capacitors.
Use parameter o4-05 [Capacitor Maintenance Setting] to reset this monitor.
Unit: 1%
Note:
Replace the electrolytic capacitor when this monitor is 90%.
V/f CL-V/f OLV CLV AOLV
Shows the operation time of the soft charge bypass relay as a percentage of the replacement life of
the soft charge bypass relay.
Use parameter o4-07 [Softcharge Relay Maintenance Set] to reset this monitor.
Unit: 1%
Note:
Replace the drive when this monitor is 90%.
