Rotations per minute vary

It is considered that conditions including the power supply and noise change whether the parameter unit is connected or disconnected, influencing the analog ... More Details >>

Relationship between frequency and load current

If the load is heavy and the output current is higher than the control value, you can adjust Pr.22 (Stall prevention operation level) to trigger the stall pr... More Details >>

Motor characteristics at low input voltage

Since the dedicated motor is designed with the rated voltage of approximately 320 V, it can produce sufficient torque for the input voltage of 380 V. Therefo... 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 >>

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 >>

RS-485 communication

It is available since June, 2007. The model is FR-E7TR. More Details >>

Specifications

It can be driven by connecting single-phase 200 V to the terminals R and S. In this case, the load current must be one-third or less of the inverter rated cu... More Details >>

Noise filter

The noise filter is not built-in the FR-E700 series. It is built in the FR-A700/F700 series with the 55K or lower capacity. More Details >>

Wiring and terminal

The ferrule terminal or single wire can be used for the control circuit wiring. More Details >>

FR-A5AY

The FR-A5AY cannot be used in the FR-A700 (F700(P)). It cannot be installed due to the difference of the connector shape. More Details >>
