Reversible operation of agitator

When the inverter's forward and reverse terminals are switched instantaneously, the inverter decelerates and then switches the rotation direction. It can swi... More Details >>

Current increase at motor stop

If the current increases when the motor stops under V/F control (at low speed under a light load), the motor is considered to be in the overexcitation state.... More Details >>

Imbalanced input side power supply

1. Power supply voltage phase imbalance toleranceMitsubishi inverter's input power supply voltage phase imbalance tolerance is ±3%.If the phase imbalance exc... More Details >>

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 >>

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 >>

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 >>

FR-A5CN03

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 >>

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 >>
