Connection with personal computer

Connection method for the A500 and E500 is shown in the figure below. The figure is given in an Excel file. Figure 1 More Details >>

Overcurrent at low speed

"8" display in offline auto tuning means forced stop by the operator. This means that you stopped operation before tuning completes. 　With this forced stop, ... More Details >>

Simple torque control using stall prevention function

Basically, torque control cannot be performed. Instead, control speed to adjust the winding torque. It is possible to use the current limit function to preve... 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 >>

Monitor output

The FM output is the 1440 Hz, 1 mA pulse train output at full scale. You can input to the programmable controller if it has a pulse train input. A68AD does n... More Details >>

Inverter data cannot be read

It is considered that communication settings between the inverter and personal computer do not match. Check if settings such as communication rate and stop b... More Details >>

Inverter control power supply

The FR-E540 uses common input for the control power supply and main circuit power supply. (It has only one power supply input terminal.) Therefore, you canno... 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 >>

FR-E710W

Yes. The model is FR-E710W. The input is single-phase 100 V, but the output is three-phase 200 V. More Details >>

Monitor value at CC-Link communication

The data of output frequency, output current, and output voltage are retained at alarm occurrence, but other monitors are not. More Details >>
