Useful functions for each of the design, operation, and maintenance processes of systems

FR-E800 inverters have various functions to attract more customers by offering safe and reliable operation for a long time. This is the time to start innovation in the fields of manufacturing.

Toward smart factory

Supporting various networks enable flexible system design.

Compatibility with global networks

Supported protocols

Supporting various topologies

Two Ethernet ports are provided as standard, enabling flexible connection in line topology without using a switching hub. (Ring topology will be supported later. For PROFINET, only line topology and star topology are supported.)

Complex networks can be created just by connecting devices with a cable to a free port. The network can even accommodate changes in the specifications of devices.

Line topology

The total wiring length can be minimized for large or extensive systems.
Eliminating a switching hub allows more flexible installation of inverters even in a narrow space.

Star topology

A fault in one device does not affect other devices. Fast recovery is enabled when a fault occurs as it is easy to know which device is faulty.

Enabling construction of a small-scale synchronous system of inverters

Inverter-to-inverter link function

Communication between multiple inverters is carried out through the I/O device and special register transmission of the PLC function. A small-scale system can be created by connecting multiple inverters via Ethernet. (The FR-A800-E inverter or the FR-F800-E inverter can be mixed in the system.)

Supporting various systems and environments

Expanded capacity range

The FR-E820-11K to 22K models and the FR-E840-11K to 22K models are added. The capacity range is extended as compared to the preceding FR-E700 inverters.

Approximately 20% less space is required for installation in an enclosure as compared to the layout using our FR-A820-22K inverters. Users can select the most suitable layout in a given space. (Note that the installation depth is greater when the plug-in option is connected.)

• When the surrounding air temperature is 40°C or less, multiple inverters can be installed side-by-side.
• Since multiple ratings are supported, the inverter can be used to drive a 30kW motor.

Improved environmental resistance

Various applications are supported by allowing for corrosive environments or a wide range of surrounding air temperatures.

• Surrounding air temperatures between -20°C and 60°C^＊1 are supported. (-10°C to +50°C for the FR-E700)
• Inverters with circuit board coating (IEC 60721-3-3 3C2)^＊2 are available for improved environmental resistance.

            ＊1: Derating required for 50°C or higher
            ＊2: Coated model (-60/-06) only.

Effective solution for downsizing equipment

For the three-phase input model, two rating types of different rated current and permissible load can be selected by setting parameters. The choice of inverters is widened for intended applications of users. When users select the LD rating for light duty applications, inverters with smaller capacities can be used as compared to the FR-E700 series inverters. For example, when the LD rating (light duty) is selected for a 22K inverter, the inverter can drive a motor with a capacity up to 30kW.

Enabling installation in various environments

Installation outside of the enclosure enables installation closer to machines (FR-E846). Since the inverter is compatible with hostile environments such as high humidity and dusty environments, users can easily install the inverter near the machine or in available spaces.
It is possible to reduce line noise by shortening the wiring length between the inverter and the motor.

Customizing inverter operation for each machine

PLC function

In accordance with the machine specifications, users can set various operation patterns: inverter movements at signal inputs, signal outputs at particular inverter statuses, and monitor outputs, etc. Operation of the system can be customized by the inverter alone.Parameters and setting frequency can be changed at the program. Control programs can be created in sequence ladders using the inverter setup software (FR Configurator2).

Accurate and stable transfer - Position control

Vector control enables accurate transfer of glass or PET bottles to the filling position.

Positioning function (point table method)

Position data (target position, speed, acceleration/deceleration time) and so on can be set in the parameters.

Positioning is possible for up to 7 points.

Positioning operation is performed by selecting point table numbers with external interface signals.

Continuous positioning is possible.

Energy saving with motors

PM motor

The PM motor achieves even higher efficiency as compared to the general-purpose motor.

The setting for driving PM motors is enabled just by setting parameters.

Why is a PM motor so efficient?

• No current flows to the rotor (secondary side), and no secondary copper loss is generated.
• Magnetic flux is generated with permanent magnets, and less motor current is required.

Supporting step-by-step energy saving solution

Further energy saving operation is enabled by using IE3/IE4 induction motors or permanent magnet embedded (PM) motors.

FR-E800 inverters support both induction motors and PM motors, enabling step-by-step replacement of existing devices. Users can replace inverters first and then motors. There is no need to replace them all at once.

Energy saving with inverters

Advanced optimum excitation control

A large starting torque can be provided with the same motor efficiency under Optimum excitation control. Without the need of troublesome adjustment of parameters (acceleration/deceleration time, torque boost, etc.), acceleration is done in a short time. Also, energy saving operation with the utmost improved motor efficiency is performed during constant-speed operation.

When Advanced magnetic flux vector control is selected, Advanced optimum excitation control is available.

Energy saving monitoring

The energy saving effect can be checked using an operation panel, output terminal, or network.

The output power amount measured by the inverter can be output in pulses. The cumulative power amount can be easily checked.^*1
