(*1) When the power supply voltage is 400 V, 440 V, or 460 V, the output voltage is approximate 640 VDC, 686 VDC, or 710 VDC,
respectively.
(*2) When the power supply voltage is 380 to 398 V/50 Hz and 380 to 430 V/60 Hz, tap-switching is required in the converter. When
the power supply voltage is less than 400 V, it is necessary to decrease the converter capacity.
(*3) Voltage unbalance (%) = (Max. voltage (V) - Min. voltage (V)) / Three-phase average voltage (V) x 67

(*1) When the power supply voltage is 420 V or above and the converter is running under 50% load or above, the power factor
decreases to about 0.95 (only under regenerative control).

Three-phase three lines, 380 to 440 V 50 Hz, 380 to 460 V 60 Hz
Voltage: -15 to +10%, Frequency: ±5%, Voltage unbalance: 2% or less
AVR constant control with DC ACR minor
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, power running, regenerative operation, ready-to-run, alarm output
(for any alarm), etc.
Switching between CT and VT modes.
CT: 150% of overload rating for 1 min
VT: 120% of overload rating for 1 min
(Converters of 500 kW or above are fixed in CT mode.)
Fixed to high carrier frequency
0.99 or above (under 100% load) ( * 1)
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.
Controls the power not to exceed the preset limit value.
