Encoder feedback control wire

If the phase A and phase B are connected reversely, encoder feedback control is not performed. Instead, the inverter is operated in normal control (V/F contr... More Details >>

Selection of high-duty brake resistor

Inverter general matters

1. To perform emergency stop, it is recommended to have the motor coast and stop it using a mechanical brake.In this case, the output stop (MRS) signal is in... 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 >>

Output current detection

The FR-A500 series that is the successor of the FR-A200E series has a function similar to output current detection of the FR-E500. Consider using the FR-A500... More Details >>

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 >>

Coasting operation of the inverter

To use an inverter using the external contact coast to stop (to shut off the inverter's output), short-circuit the terminals MRS and SD.For CC-Link operation... 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 >>
