High-function General-purpose Inverter RX2 Series User’s Manual
*1. The rated input currents shown in the table are the values when the rated current is output. The values vary depending on impedance on the power supply
(wiring, breaker, input reactor option, etc.)
*2. The power supply equipment capacities shown in the table are the values when 220V rated current is output. The values vary depending on impedance on
the power supply (wiring, breaker, input reactor option, etc.)
*3. The setting of rated values for carrier frequencies [bb101]/[bb201] are internally limited in accordance with the description. Also, it is recommended to set
values equivalent to or above (maximum output frequency for driving ×10) Hz for the setting of carrier frequencies [bb101]/[bb201]. Also, in the case of
induction motor (IM) control, for items other than those subject to V/f control, it is recommended to set carrier frequency at 2kHz or more. In the case of
synchronous motor (SM)/permanent magnet motor (PMM) control, it is recommended to set carrier frequency at 8kHz or more.
*4. The value of the sensor-less vector control applied to the ND rating in the Standard motor. Torque characteristics may vary depending on the control
method and the motor used.
*5. Based on self declaration.
