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 >>

Energy consumption

Using a general-purpose inverter to drive a three-phase induction motor can save energy under the following two types of loads (application): 　　1. Constant-t... 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 >>

Speed command by CC-Link communication

It is not possible when the speed command is communication. 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 >>

System environment variable of the Modbus-RTU communication

It decelerates and stops. The operation is the same as the one when the Bit of forward rotation command and reverse rotation command are turned OFF. More Details >>

IPM motor drive

Overshooting of the speed due to the acceleration/deceleration may be the cause. Overshooting is more likely to occur when the load inertia is too high. As a... More Details >>

MT-BU5

No, the MT-BU5 is unavailable because it is the conventional model. Use the FR-BU2. More Details >>

FR-HC2

Yes, the circuit board coating and conductive plating are applied to the HC2 as standard. More Details >>

Trace function

The ST1 is a setting file and the TR1 is a waveform file. More Details >>
