Installing reactor for suppressing harmonics

You can connect multiple inverters to a single reactor. In this case, the load seems to be light from the reactor unless all of the inverters are rotating an... More Details >>

Notes on using single-phase 200 V

With the single-phase 200 V input specifications, the input cable current increases. Therefore, choose larger power supply capacity and NF/MC than three-phas... More Details >>

Interval of next power ON

The instantaneous power failure error occurs when the power is turned ON instantaneously (within 100 ms) after the power is turned OFF. When the motor is coa... More Details >>

Operation of the motor with a brake

For the general-purpose inverter, the motor stop cannot be detected accurately because the actual motor speed from a motor is not input. In general, the RUN ... More Details >>

Monitor

The output current monitor of the inverter displays the output current effective value of the three phases measured by the current sensor. It does not displa... More Details >>

Earthing (grounding) of FR-A7NC (E kit)

There is no problem, however, earthing (grounding) from each FG terminal is recommended to avoid the influence of noises. More Details >>

Wiring of CC-Link communication cable

The communication is established if DA, DB, and DG are connected each other. More Details >>

PID control of CC-Link communication

When performing the PID control by CC-Link communication, the X14 signal is disabled. More Details >>

Speed command by CC-Link communication

It is not possible when the speed command is communication. More Details >>

Writing set frequency by CC-Link communication

No error will occur because up to 400 Hz that is the upper limit of the setting range can be written. More Details >>
