A100 inverter loss

The inverter efficiency (power factor) for the inverter alone is approximately 75 to 80%. However, by installing the power factor improving DC reactor to the... More Details >>

Functions available when using inverter on CC-Link

You can use the regular terminal block wire functions during CC-Link operation. 　Set Pr.338 (Operation command source) and Pr.339 (Speed command source) to e... More Details >>

Countermeasures when input power supply is turned off upon equipment fault

1. When the inverter power supply is turned OFF, the inverter is disconnected from the CC-Link network. However, since the CC-Link master station has the aut... More Details >>

Is the number of writing times of the parameter memory limited?

1. The limit of the parameter writing is 100,000 times. 2. Parameter error occurs. Since the data in the ROM may be broken, the inverter may become unavailab... More Details >>

Current monitor display

The current monitor displays the average value of the three-phase current. The three-phase voltage is not incorporated for the voltage monitor. The output vo... More Details >>

Issues of driving the wound rotor motor inverter

The wound rotor motor can be used in the same way as cage-induction motors by shortening the resistor at the secondary side. More Details >>

Remote register when instruction code execution request is issued at CC-Link communication

The value "0" is stored. More Details >>

Checking bit state by CC-Link communication

Because the H0F monitor only observes the ON/OFF of the hardware, it cannot be checked. More Details >>

Inverter installation when using the FR-A7NCE

Normally, the required space for A700 3.7K or lower is 1 cm. However, when using CC-Link IE, it needs to be separated for 5 cm or more to pass the cable. More Details >>

Noise effect of CC-Link IE communication

The same test as CC-Link is performed, and we confirmed no problem. More Details >>
