400 Hz output setting

Change Pr.18 (High speed maximum frequency) to 400 Hz.If you are using the analog command to set the frequency, calibrate the 400 Hz frequency with Pr.903. More Details >>

Terminal FM

Since the terminal FM is designed with 8 V peak pulse voltage output, it cannot output 10 V.Since the terminal AM is an analog output of 0 V to 10 V, use thi... More Details >>

Two-rank up maximum short-time torque

It is not possible to generate torque larger than the maximum possible torque of the motor by increasing the inverter's capacity.Even when the inverter is up... More Details >>

Brake sequence function

Since the brake sequence function requires Advanced magnetic flux vector control and advanced flux control is applied to 0.4 kW or higher motors, you cannot ... More Details >>

Countermeasure against the fault occurrence

When a CC-Link communication fault occurs, the option error (OP3) occurs on the inverter and the output is shut off, and the motor starts coasting. When usin... 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 >>
