Countermeasure against harmonics

Perform calculation given in the harmonic suppression guidelines, and if the limit value is exceeded, you may also need to insert the ACL. Note that you cann... More Details >>

Inverter current value

1. As the measurement condition is unknown, the possible cases are as follows: - If you measured the current on the input side of the inverter, since the cu... More Details >>

Inverter with one-rank higher capacity

An inverter with one-rank higher capacity is often used when a high torque is required for a short period of time. (Examples)- When rapid acceleration/decele... More Details >>

Can I use a motor of which capacity is larger than the inverter capacity?

Even when the actual load (torque) is half of the motor capacity, the current output from the inverter to the motor is not reduced to the half. Therefore, it... More Details >>

FR-A5CN

When the heat sink is outside, 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. More Details >>

Wire length between inverter and motor

1. Wiring length between the inverter and the motor should be 500 m or less. For 0.75 kW or lower motors, the following relationship is true: Capacity... More Details >>

Wiring of CC-Link communication cable

The communication is established if DA, DB, and DG are connected each other. More Details >>

FR-A7NCE connector

It is tilted to wire the cable easily. More Details >>

Inverter installation when using the FR-A7NCE

Normally, the required space for A700 3.7K or lower is 1 cm. However, when using CC-Link IE, it needs to be separated for 5 cm or more to pass the cable. More Details >>
