Speed adjustment of multiple inverters using variable resistor

You can connect up to three inverters in parallel to an external variable resistor. Refer to the figure below for a connection example. By setting parameters... More Details >>

Input power supply circuit breaker

When using a motor circuit breaker, the rated current of the motor circuit breaker to use must be equal to or higher than the rated current of the circuit br... More Details >>

Short-circuiting frequency setting terminals

You can short-circuit the terminals 10 and 2.If you are considering to perform operation at the maximum frequency, consider using the high-speed command RH o... More Details >>

Influence on inverter at motor coasts to stop

An induction motor does not act as a power generator unless voltage is applied to it.Therefore, just rotating due to coasting does not affect the inverter. 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 >>

Harmonic suppression guidelines

A 200 V class inverter of 3.7 kW or smaller is the target of the harmonic suppression guidelines for household appliances and general-purpose products, and i... More Details >>

Installation of external thermal

Since the inverter has a built-in motor overheat protective function called "electronic thermal O/L relay", the external thermal is not required. (If you use... More Details >>

Countermeasure against the harmful effect on model selection and other devices

Harmful elements that may affect other devices through the input side of the inverter include noise and harmonics. Harmonics can be reduced by inserting the ... More Details >>

Common connection of the terminal SD

There is no problem for only the terminal SD connection because undesirable current will not be flown. More Details >>

Comparison of the speed change rate

Speed fluctuation ratio differs depending on the control method as follows. - V/F control?????????2 to 5% (At the encoder feedback: 0.02%)- General-purpose m... More Details >>
