Advanced magnetic flux vector control

Set "13" in Pr.71. Always perform auto tuning. More Details >>

Monitor

The output current monitor of the inverter displays the output current effective value of the three phases measured by the current sensor. It does not displa... More Details >>

Current measurement method

When measuring current, if you open the output side while current is flowing on the input side, high voltage is induced and dielectric breakdown may occur wi... More Details >>

Inverter signal input speed

There is a 10 ms delay after the inverter recognizes the start command (STF OR STR) before it starts decelerating. The delay is 10 ms. A delay of 100 ms is i... More Details >>

Stall mode

Since the stall prevention function works during acceleration and the inverter does not reach the commanded speed, set Pr.156 (Stall prevention operation sel... More Details >>

Controlling multiple VVVFs via communication from personal computer

To control multiple inverters using arbitrary signals (4 to 20 mA) simultaneously, it is recommended to connect the signals (4 to 20 mA) in series. (This doe... More Details >>

Number of inverters that can be connected to a 20 A branch circuit breaker

The basic idea is the same, but the total capacity should be 3.7 kW. (The maximum capacity is also 3.7K.) More Details >>

Certificate for special tax reduction for first year facilities

The special tax reduction for first year facilities is the taxation system for promoting investment in the reform of the energy supply. The required certific... More Details >>

Waveform improvement

A reference sine wave signal is generated inside the high power factor converter, and transistors are configured and PWM switching is performed in the conver... More Details >>
