Noise

The noise amount does not change because the carrier frequency does not change. More Details >>

Stop selection

No. During JOG operation, deceleration stop is performed even though Pr.250 is set. More Details >>

Stop-on-contact control

When the brake sequence function is enabled, the RT signal is disabled and the stop-on-contact control cannot be performed. More Details >>

Communication EEPROM write selection (Pr.342)

They are cleared by the RES signal from the external terminals or inverter reset from the communication. More Details >>

System environment variable of the Modbus-RTU communication

It decelerates and stops. The operation is the same as the one when the Bit of forward rotation command and reverse rotation command are turned OFF. More Details >>

Inverter installation when using the FR-A7NCE

Normally, the required space for A700 3.7K or lower is 1 cm. However, when using CC-Link IE, it needs to be separated for 5 cm or more to pass the cable. More Details >>

Issues of driving the wound rotor motor inverter

The wound rotor motor can be used in the same way as cage-induction motors by shortening the resistor at the secondary side. More Details >>

Long wire to terminal FM

Although you can connect an analog or digital indicator to the terminal FM, use an analog indicator since the wiring length is long. (The maximum wiring leng... More Details >>
