Inverter output stop

1. Such a behavior does not usually happen. 　(1) The operation command (STF) is not input, contact faults are present, or wire is broken. 　(2) The output shu... More Details >>

How can I calculate the processing torque from the measured power?

You can calculate the torque from the power. 　From the general equation: Pout = ωn × TT = (Pout × τ)/ωnPout: Measured valueωn: Actual motor shaft angular fre... More Details >>

Concurrent monitoring of running frequency, output voltage, and output current

Add an analog output by the FR-A5AY.Monitor the three output; output AM (0 to 5 (10) V) and optional 4 to 20 mA, and 0 to 5 (10) V. 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 >>

Angular velocity change control

The inverter itself does not have a function to detect the rotation angle and change the velocity accordingly. Therefore, to implement required control, it i... More Details >>
