Difference between multi-function and standard products

The following are added to the multi-function product in addition to the standard product: - Input terminal function selection (X1 to X3)- Warning NO contact... More Details >>

How many inverters can be connected?

Up to 32 units can be connected. (This is because the inverter communication conforms to RS-485.) More Details >>

Regenerative power flow

If all inverters are in regenerative operation, the regenerative power is regenerated to the power supply. If one of the inverters is power driving, the rege... More Details >>

Output voltage

The output voltage is approximately 300 VDC for the 200 V class and approximately 600 VDC for the 400 V class. 　The output voltage fluctuates due to fluctuat... More Details >>

Certificate for special tax reduction for first year facilities

The special tax reduction for first year facilities is the taxation system for promoting investment in the reform of the energy supply. The required certific... More Details >>

Controlling multiple VVVFs via communication from personal computer

To control multiple inverters using arbitrary signals (4 to 20 mA) simultaneously, it is recommended to connect the signals (4 to 20 mA) in series. (This doe... More Details >>

Compatibility with Y-△ motor and others

1. You can connect them using △ connection. 2. No problem with connecting four Y-△ motors. (Connect all four motors using △ connection.) (Note that the inver... More Details >>

Operation frequency

I cannot answer clearly because the load is unknown. The operation cycle of operating for 10 seconds and stopping for 10 seconds is OK, but it is questionabl... More Details >>

Part selection

1. Choose the circuit breaker based on the inverter capacity. 2. Also, choose the brake resistor based on the inverter capacity. 3. Choose the AC reactor bas... More Details >>
