Do noise and leakage current increase?

During non-low-noise operation (initial setting) with the carrier frequency of 1 kHz, both noise and leakage current levels are almost same as the Z024 serie... More Details >>

How many inverters can be connected?

Up to 32 units can be connected. (This is because the inverter communication conforms to RS-485.) More Details >>

What parameters (settings) are available?

The following three functions can be set: - Acceleration/deceleration time- Electronic thermal O/L relay- Maximum frequencyThe parameter unit is not used but... More Details >>

Inverter current characteristics

In general, relationship between T (torque), K (constant), V (voltage), I (current), and F (frequency) is expressed as "T = K × (V/F) × I". Since (V/F) is co... More Details >>

Compressor

You can use an inverter for fan and pump with the compressor, but it is not recommended for an application that the motor load rapidly increases. More Details >>

Load current limit of inverter

You can input current from the terminal AM of the inverter to the programmable controller (for A/D conversion) and control the speed with the software of the... More Details >>

Vector motor

The constant-torque motor and vector motor are the induction motors, which consist of the stator core, gap, and rotor core. For the constant-torque motor, th... 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 >>

Real sensorless vector control

No, Real sensorless vector control cannot be used in the FR-E700. More Details >>
