Item Explanation Remarks
Running/Stopping
Speed monitor (reference frequency, output frequency, motor speed, load shaft speed, line speed,
and speed indication with percent), output current [A], output voltage [V], calculated torque [%],
input power [kW], PID command value, PID feedback value, PID output, load factor [%], motor
output [kW], torque current [%] *6 *7, magnetic flux command [%] *6 *7,
analog input and input watt-hour
Life early warning
• The life early warning of the main circuit capacitors, capacitors on the PC boards and the cooling
fan can be displayed.
• An external output is issued in a transistor output signal.
• Surrounding temperature: 40ºC
Load factor: Inverter rated current 100% (HD mode) or 80% (MD/LD mode)
Cumulative run time
• Displays the inverter cumulative run time, input watt-hour, cumulative motor run time, and the
number of startups (of each motor).
• Outputs the warning when the maintenance time or the number of start times has exceeded the
preset.
Trip mode Displays the cause of trip by codes.
Light-alarm Shows the light-alarm display
l-al
.
Display
Running or trip mode
• Trip history: Saves and displays the cause of the last four trips (with a code).
• Saves and displays the detailed operation status data of the last four trips.
Overcurrent protection The inverter is stopped for protection against overcurrent.
Short-circuit protection
The inverter is stopped for protection against overcurrent caused by a short circuit in the output
circuit.
The inverter is stopped for protection against overcurrent caused by a ground fault in the output
circuit. (200 V 22 kW, 400V 22 kW or below)
0c1
0c2
0c3
Ground fault protection
Detecting zero-phase current of output current, the inverter is stopped for protection against
overcurrent caused by a ground fault in the output circuit. (200 V 30 kW, 400 V 30 kW or above)
ef
Overvoltage protection
An excessive voltage (200 V class series: 400 VDC, 400 V class series: 800 VDC) in the DC link
circuit is detected and the inverter is stopped.
This protection is not assured if extremely large AC line voltage is applied inadvertently.
0u1
0u2
0u3
Undervoltage protection
The voltage drop (200 V class series: 200 VDC, 400 V class series: 400 VDC) in the DC link circuit
is detected to stop the inverter.
However, the alarm will not be issued when the re-starting after instantaneous stop is selected.
lu
Input phase loss protection
• Protects the inverter or stops the inverter output when an input phase loss is detected.
• When the load is small or a DC reactor is connected, a phase loss may not be detected.
lin
Output phase loss
protection
Detects breaks in inverter output wining during running, to shut off the inverter output.
0pl
Stop the inverter output detecting excess cooling fan temperature caused by a cooling fan fault or
overload.
Stop the inverter output detecting a fault of inner agitating fan.
(200 V 45 kW, 400 V 75 kW or above)
0h1
Stop the inverter output detecting an abnormal temperature inside the inverter unit caused by a
cooling fan fault or overload.
0h3
Overheat protection
Protect the braking resistor from over heat by setting the braking resistor electronic thermal
function.
dbh
Overload protection
Stops the inverter output upon detection of the abnormal heat sink temperature and switching
element temperature calculated with the output current.
0lu
External alarm input With the digital input signal THR opened, the inverter is stopped with an alarm.
0h2
Fuse blown
Stop the inverter output detecting the fuse breaking of the main circuit in the inverter.
(200 V 75 kW, 400 V 90 kW or above)
fu5
Protection
Charger circuit fault
Stop the inverter output detecting the charge circuit abnormality in the inverter.
(200 V 37 kW, 400 V 75 kW or above)
pbf
*6 Available under vector control without speed sensor.
*7 Available under vector control with speed sensor. (PG option required)
