YASKAWA SIEP YAIP1U 01C AC Drive - P1000 Technical Manual
Description
Displays the time when the seventh most recent fault occurred.
Displays the year when the eighth most recent fault occurred.
Displays the date and day when the eighth most recent fault occurred.
Displays the time when the eighth most recent fault occurred.
Displays the year when the ninth most recent fault occurred.
Displays the date and day when the ninth most recent fault occurred.
Displays the time when the ninth most recent fault occurred.
Displays the year when the tenth most recent fault occurred.
Displays the date and day when the tenth most recent fault occurred.
Displays the time when the tenth most recent fault occurred.
Description
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.
Displays the number of times the Run command is entered. Reset the
number of Run commands using parameter o4-13. This value will reset to
0 and start counting again after reaching 65535.
Displays the cumulative operation time of the cooling fan. The default value
for the fan operation time is reset in parameter o4-03. This value will reset
to 0 and start counting again after reaching 99999.
Displays main cooling fan usage time as a percentage of its expected
performance life. Parameter o4-03 can be used to reset this monitor.
Replace the fan when this monitor reaches 90%.
Displays main circuit capacitor usage time as a percentage of their expected
performance life. Parameter o4-05 can be used to reset this monitor.
Replace the capacitor when this monitor reaches 90%.
Displays the soft charge bypass relay maintenance time as a percentage of
its estimated performance life. Parameter o4-07 can be used to reset this
monitor.
Replace the soft charge bypass relay when this monitor reaches 90%.
Displays IGBT usage time as a percentage of the expected performance
life. Parameter o4-09 can be used to reset this monitor.
Replace the IGBT when this monitor reaches 90%.
Displays the heatsink temperature.
Lights all segments of the LED to verify that the display is working
properly.
Monitors the drive output power. The value is shown as a 9-digit number
displayed across two monitor parameters, U4-10 and U4-11.
Example:
12345678.9 kWh is displayed as:
U4-10: 678.9 kWh
U4-11: 12345 MWh
