Constant Torque

Notes:

(*1) Indicated capacities are at the rated output voltage 230V for the 230V series and 460V for the 460V series. The rated capacity will be lowered

if the supply voltage is lower.

(*2) In the case of a low impedance load, such as a high-frequency motor, the current may drop below the rated value.

(*3) The output voltage cannot exceed the input supply voltage.

(*4) The taps within the inverter must be changed for an input power supply rated at 380 to 398V/50 Hz or 380 to 30V/60 Hz.

(*5) If the imbalance between phases exceeds 2%, use a power-factor correcting DC reactor(DCR). Please refer to the equation on the next page.

(*6) The test was conducted under the standard load conditions stipulated by the JEMA committee (at the load equivalent to 85% of the

nominal applied motor hp).

(*7) Indicates the values required when using a power factor correcting DC reactor (DCR) with a loaded nominal applied motor

(optional for inverters of 75 hp/CT, 100 hp/VT or less).
