Saves and displays the most recent 10 alarms.
Saves and displays the detailed information of the trip cause for the previous
alarm.
Displays input power, input current in RMS, input voltage in RMS, DC link
bus voltage and power supply frequency.
Allows the user to measure the load factor with the keypad.
Allows the user to specify or refer to function codes in any of the three
languages--Japanese, English and Chinese.
Lights when the DC link bus capacitor is charged.
Name
Connects with the three-phase input power lines through a
dedicated reactor.
Connects with the power input terminals P(+) and N(-) on an
inverter.
Grounding terminal for the converter's chassis (or casing).
For a backup of the control circuit power supply, connect the power
lines same as that of the main power input.
Voltage detection terminals for the internal control of the converter.
Connect with the power supply side of the dedicated reactor or
filter.
Detection terminal for AC fuse blown.
Short-circuiting terminals [RUN] and [CM] runs the converter;
opening them stops the converter.
When the converter stops due to an alarm, removing the alarm
factor and short-circuiting the terminals [RST] and [CM] cancels
the protective function, restarting the converter.
