Difference from general-purpose inverter

While the inverter uses open-loop (V/F) control, it uses semi-closed loop vector control (constant current control). This enables output of stable torque esp... More Details >>

Vector inverter option

Just by adding this option, encoder pulses connected to the inverter or option are output.You can also divide the pulse train output. More Details >>

Manufacturing of 6P dedicated motor

We cannot manufacture a 6P by SF-VR dedicated motor. Use a motor with 6P encoder. More Details >>

Small capacity vector inverter dedicated motor

We offer 5.5 kW or higher SF-VR dedicated motors and do not offer small capacity (3.7 kW or lower) motors. If you need small capacity (1.5 kW to 3.7 kW), use... More Details >>

Use of general-purpose servo motor

You can operate it by adjusting the motor constant by the auto tuning function. (Note that the same characteristics as operated by the servo amplifier MR-VA ... More Details >>

Coasting to stop method

Use Pr.17 (Input terminal assignment) to assign MRS to the terminals DI1, DI2, and DI3. More Details >>

Encoder cable length restriction

If the cable length is longer than 100 m, speed may not be read correctly due to voltage drop and waveform deformation of the encoder signal. Therefore, use ... More Details >>

Reset selection

The specifications of the FR-V200E series do not allow for choosing from "Reset input always enabled" and "Reset input enabled only when the protective funct... 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 >>

Comparison with FR-A200E

In addition to speed control, you can also select torque control as well as you can perform position control using an option. The speed control range is as l... More Details >>
