Synchronous operation of two motors

When synchronously operating two motors, you need to detect speed from both motors. Each inverter is controlled based on this speed detection signal. As an e... More Details >>

Installation dimensions of the heat sink panel through attachment

The heat sink panel through attachment to the FR-A520-5.5K inverter consist of the top installation frame, bottom installation frame, and upper cover. The to... More Details >>

Using dedicated motor

Since the inverter power supply uses the single-phase input, you cannot use a 0.75K inverter with a 0.6 kW motor to draw the maximum ability of the motor. To... More Details >>

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 >>

Can I use a motor of which capacity is larger than the inverter capacity?

Even when the actual load (torque) is half of the motor capacity, the current output from the inverter to the motor is not reduced to the half. Therefore, it... More Details >>

Inverter input current

Since the input current has a distorted waveform and the waveform ratio is low, the total inverter input power factor is very poor depending on the power sup... More Details >>

Part selection

1. Choose the circuit breaker based on the inverter capacity. 2. Also, choose the brake resistor based on the inverter capacity. 3. Choose the AC reactor bas... More Details >>

Parameter unit

The FR-PU02-1 cannot be used with the FR-B3 series inverters. 　Use the FR-DU04 or FR-PU04. More Details >>
