Monitor Mode
Monitor mode is the operation mode to display operating
conditions. The following data can be displayed in this mode:
• Input current *
• AC input power voltage
• DC bus voltage
• Power
• Load ratio.
* The displayed value of input current is only an approximate
value and no accuracy can be guaranteed. If you need an
accurate input current, measure it by using a dedicated
measuring device.
To select a value to monitor, press the
key or the key until the
desired value is displayed. Pressing the key or the key will
move you through the each of the displays.
The unit of the displayed value is shown by turning ON the status
LEDs as follows:
• "A" : Shows the unit when the input current is displayed.
• "V" : Shows the unit when monitoring the AC input power
voltage or the DC bus voltage.
• "KW" : Shows the unit when monitoring the power.
• Turning OFF all LEDs : Shows the unit when the load ratio is
displayed.
In both cases of monitoring the AC input power voltage and the DC
bus voltage, the "V" status LED is ON. You can judge which item
is being monitored, by the display order. The unit of the load ratio
is percent (%). But in this case, no status LED is ON.
In case of monitoring the power, the "KW" status LED is ON
continuously when the operation is in power running, and the "KW"
status LED flashes when the operation is regenerative.
In monitor mode, the "PROGRAM" status LED is turned OFF,
indicating that the operation panel is not in program mode.
When any fault occurs, the operation panel cannot be changed to
monitor mode.
