YASKAWA ELECTRIC SIEP C710606 44B YASKAWA AC Drive T1000V Technical Manual
Description
Displays the cumulative operation time at the fifth most
recent fault.
Displays the cumulative operation time at the sixth most
recent fault.
Displays the cumulative operation time at the seventh
most recent fault.
Displays the cumulative operation time at the eighth most
recent fault.
Displays the cumulative operation time at the ninth most
recent fault.
Displays the cumulative operation time at the tenth most
recent fault.
U4: Maintenance Monitors
Use U4 parameters to display drive maintenance information.
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 in as a percentage
of their expected performance life. Parameter o4-03 can
be used to reset this monitor.
Displays main circuit and control capacitor usage time in
as a percentage of their expected performance life. As the
ambient temperature affects the lifespan of these
capacitors, the temperature must be set to parameter L8-
12. The maintenance of the capacitors is needed when
U4-05 = 100%. Reset U4-05 using parameter o4-05.
Displays the soft charge bypass relay maintenance time as
a percentage of the estimated product life. Parameter o4-
07 can be used to reset this monitor.
Displays IGBT usage time as a percent of expected
performance life. Parameter o4-09 can be used to reset
this monitor.
<45>
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
Displays the peak hold current during run.
Displays the output frequency when operating at the peak
hold current.
