(Note 1) The specifications are as shown above for function code F03 = 0 (MD (CT)).
(*1) Customer orders for 220 to 230 V/50 Hz models are accepted.
(*2) When the power supply voltage is 200 V, the output voltage is approximately 320 VDC, 343 VDC when 220 V, and 355
VDC when 230 V.
(*3) Interphase unbalance ratio (%) =
Max. voltage [V] - Min. voltage [V]
Three-phase average voltage
×67
(*4) When equipped with OPC-RHCE-TBSI-2, the carrier frequency with no transformer automatically becomes 7.5 kHz.
(*5) When equipped with OPC-RHCE-TBSI-2, the carrier frequency with no transformer automatically becomes 5 kHz.
(*6) Be sure to connect to a power supply with the above required power supply capacity or higher.
(If the power supply capacity is insufficient, the converter or inverter may suffer damage due to waveform distortion at the
power supply side.)
If a power supply boosted with a low-capacity transformer is used for the main circuit power supply, etc. for performing a
control panel sequence check in particular, there is a possibility that problems may occur. In cases such as this, open the
converter “RUN-CM”, and perform a sequence check of other parts without running the converter.
