Since the heat sink and fan are not waterproof, you need to enclose them so that they are not exposed to the spray of water. If you use the inverter (heat si... More Details >>

Motor characteristics at low input voltage

Since the dedicated motor is designed with the rated voltage of approximately 320 V, it can produce sufficient torque for the input voltage of 380 V. Therefo... More Details >>

Number of years of service life designated by law

The number of years of service life of the inverter is not designated by law. More Details >>

Inverter loss

The inverter efficiency changes depending on the inverter output frequency, carrier frequency, motor capacity, and load factor. When the inverter and motor h... More Details >>

PWM control

PWM is an acronym for Pulse Width Modulation and varies the switching pulse width of transistors.　This method creates many pulses within a single cycle of th... More Details >>

Second deceleration time setting

Your suggestion is fine, but note that deceleration stop is naturally not available in case of an inverter error.In addition, considering regenerative power,... More Details >>

Applied motor selection

As the motor operates with the electronic thermal O/L relay characteristics for the standard motor, the thermal error occurs if the motor continuously operat... More Details >>

Relationship between undervoltage warning and instantaneous power failure

When an instantaneous power failure occurs and the inverter's bus voltage drops below the standard value, it outputs an undervoltage warning and stops its ou... More Details >>
