SIEPYEUOQ2A01A AC Drive Q2A Technical Manual
Description
Shows the cumulative operation time of the drive.
Use parameter o4-01 [Cum.Oper TimeSetting] to reset this monitor. Use parameter o4-
02 [Cum.Oper TimeSelect] 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. The value then resets and
starts counting again from 0.
Unit: 1 h
Note:
The Modbus communication data is shown in 10 h units. Use register 0099H for
data in 1 h units.
Use parameter o4-13 [NumOfRunCom Init Counter] to reset this monitor. The
maximum value that the monitor will show is 65535. The value then resets and starts
counting again from 0.
Unit: 1
Shows the cumulative operation time of the cooling fans.
Use parameter o4-03 [Fan.Oper Setting] to reset this monitor. The maximum value that
the monitor will show is 99999. The value then resets and starts counting again from 0.
Unit: 1 h
Note:
The Modbus communication data is shown in 10 h units. Use register 009BH for
data in 1 h units.
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.Oper Setting] to reset this monitor.
Unit: 1%
Note:
Replace the cooling fans when this monitor is 90%.
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 [Cap.Maint.Setting] to reset this monitor.
Unit: 1%
Note:
Replace the electrolytic capacitor when this monitor is 90%.
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 [PreChgRly Preset Maintenance Cnt] to reset this monitor.
Unit: 1%
Note:
Replace the drive when this monitor is 90%.
Shows the operation time of the IGBTs as a percentage of the replacement life of the
IGBTs.
Set parameter o4-09 [IGBT Preset Maintenance Cnt] to reset this monitor.
Unit: 1%
Note:
Replace the drive when this monitor is 90%.
Shows the heatsink temperature of the drive.
Unit: 1 °C
Turns on all of the keypad LEDs to make sure that the LEDs operate correctly.
Push with U4-09 shown on the keypad.
All LEDs on the keypad will turn on.
Note:
When Safety input 2 CH is open (STo), READY will flash.
Displays the lower 4 digits of the watt hour value for the drive.
Unit: 1 kWh
Note:
The watt hour is displayed in 9 digits. Parameter U4-11 [kWh Upper 5Digits]
displays the upper 5 digits and U4-10 displays the lower 4 digits.
Example for 12345678.9 kWh:
U4-10: 678.9 kWh
U4-11: 12345 MWh
