Turn spare inverters into converters

Changeover between inverter and high power factor converter

Install the FR-A8AVP (option) in a separated converter type inverter to use it as a high power factor converter. To use the converter, the following options are needed: phase detection transformer box, dedicated filter reactor, dedicated reactor for PWM control, dedicated filter capacitor, inrush current limit resistor, etc.
They can be switched to a converter and back to an inverter again to match process requirements. The converter is classified as the self-excitation three-phase bridge circuit, and achieves K5 (the conversion factor) = 0. The total harmonic distortion of the input current (THDi) is 5% or less^*1, which facilitates compliance with the overseas standards related to harmonic suppression.

*1 : When the input voltage is distorted, harmonic contents increase because power harmonics flow into the converter.

Reduce the shock caused by switching the power source

Phase-synchronized bypass switching (400 V class only)

The FR-A8AVP (option) and the FR-A8VPB (option) make it possible to detect the phase of the commercial power supply. (For wiring details, refer to page 186.)
By synchronizing the inverter output with the phase of the commercial power supply, the spike in the motor current can be suppressed and shock reduced.
Furthermore, the time required for the switching is reduced, which is more beneficial for larger inverters.

Reduced tact time with functionality suited to the application

Reduced tact time

Anti-sway control

When an object is moved by a crane, swinging at the time of stopping is suppressed on the crane's transverse axis or traveling axis. This control cuts down the tact time and facilitates efficient operation.

Increased magnetic excitation deceleration

Deceleration time can be reduced without a brake resistor.
Tact time can be eliminated at conveyor lines, etc.

Selection of optimum capacity to suit the application

Multiple rating

Rated current and four different overload capacity ratings (SLD rating (super light duty), LD rating (light duty), ND rating (normal duty), HD rating (heavy duty)) can be selected with parameters. The optimum inverter can be selected to suit the application, and by selecting an inverter with SLD or LD rating, equipment size can be reduced when compared with the FR-A700 series. The HD rating is best suited for applications requiring low speed and high torque.
If using an inverter with capacity of 75K or higher, or motor with capacity of 75 kW or higher, always select and install the inverter based on the capacity of the motor with DC reactor.

PLC control with an inverter

Built-in PLC function in an inverter

PLC control

Parameters and setting frequency can be changed at the program.
Inverter control such as inverter operations triggered by input signals, signal output based on inverter operation status, and monitor output can be freely customized based on the machine specifications.
All machines can be controlled by the inverter alone, and control can also be dispersed.
Time-based operation is possible by using in combination with the real-time clock function (optional LCD operation panel (FR-LU08)).
The FR-A800-E enables communication between multiple inverters using the I/O devices and special registers of the PLC function, which can create a small-scale system by Ethernet using the inverter-to-inverter link function.
