Item Specifications
Control method AVR constant control with DC ACR minor
Running/Stopping Starts rectification when the converter is powered ON after connection.
Starts boosting when it receives a run signal (terminals [RUN] and [CM] short-circuited or a run command via the communications
link). After that, the converter is ready to run.
Running status signal Running, power running, regenerative operation, ready-to-run, alarm output (for any alarm), etc.
CT/VT switching Switching between CT and VT modes.
CT: 150% of overload rating for 1 min
VT: 120% of overload rating for 1 min
Carrier frequency Fixed to high carrier frequency
Input power factor 0.99 or above
Restart after momentary power
failure
Shields the gate when the voltage level reaches the undervoltage level if a momentary power failure occurs, and the converter can
automatically restart after the power recovers.
Control
Power limiting control Controls the power not to exceed the preset limit value.
Alarm display
(Protective functions)
AC fuse blown, AC overvoltage, AC undervoltage, AC overcurrent, AC input current error, input phase loss, synchronous power
supply frequency error, DC fuse blown, DC overvoltage, DC undervoltage, charge circuit fault, heat sink overheat, external alarm,
converter internal overheat, overload, memory error, keypad communications error, CPU error, network device error, operation
procedure error, A/D converter error, optical network error, IPM error
Alarm history Saves and displays the most recent 10 alarms.
Saves and displays the detailed information of the trip cause for the previous alarm.
Monitor Displays input power, input current in RMS, input voltage in RMS, DC link bus voltage and power supply frequency.
Load factor Allows the user to measure the load factor with the keypad.
Language Allows the user to specify or refer to function codes in any of the three languages--Japanese, English or Chinese.
Indication
Charging lamp Lights when the DC link bus capacitor is charged.
