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 >>

Can I use a motor of which capacity is larger than the inverter capacity?

Even when the actual load (torque) is half of the motor capacity, the current output from the inverter to the motor is not reduced to the half. Therefore, it... More Details >>
