Specifications

DCR built in type
■Three-phase 230V series
LD (Low Duty)-mode inverters for light load

*1

US 4P-standard induction motor

*2

Rated capacity is calculated assuming the rated output voltage as 230 V for 230 V series and 460 V for 460 V series.

*3

Output voltage cannot exceed the power supply voltage.

*4

To use the inverter with the carrier frequency of 3 kHz or more at the surrounding temperature of 40°C (104°F) or higher, manage the load so that the current comes to be within the rated ones enclosed in parentheses ( ) in continuous running.

*5

Voltage unbalance (%) = (Max. voltage (V) - Min. voltage (V) / Three-phase average voltage (V)) × 67 (IEC 61800- 3) U
If this value is 2 to 3%, use an optional AC reactor (ACR).

*6

Average braking torque for the motor running alone, without external braking resistor. (It varies with the efficiency of the motor.)

HD (High Duty)-mode inverters for heavy load

*1

US 4P-standard induction motor

*2

Rated capacity is calculated assuming the rated output voltage as 230 V for 230 V series and 460 V for 460 V series.

*3

Output voltage cannot exceed the power supply voltage.

*5

Voltage unbalance (%) = (Max. voltage (V) - Min. voltage (V) / Three-phase average voltage (V)) × 67 (IEC 61800- 3) U
If this value is 2 to 3%, use an optional AC reactor (ACR).

*6

Average braking torque for the motor running alone, without external braking resistor. (It varies with the efficiency of the motor.)
