FR-F series

We provide solutions to your energy saving needs, not to mention the leading drive performance such as its energy saving functions, low speed and high torque driving, the selectable multiple rating between two types, LD (light duty) and SLD (superlight duty) depending on the load of the fan/pump, and equipping the 24 VDC control power input as standard.

Functions Ideal for Fans and Pumps

Multiple rating

The rating can be selected between the two types (LD (light duty) or SLD (superlight duty)) depending on the load of the fan/pump to be used. The optimum inverter capacity can be selected suitable for the motor to be used.
For the 200 V class 90K or higher and the 400 V class 75K or higher, a motor with one-rank higher capacity can be combined.

Load	Rating	Overload current rating
Superlight duty	SLD rating	110% 60 s, 120% 3 s (inverse-time characteristics) at surrounding air temperature of 40°C
Light duty	LD rating	120% 60 s, 150% 3 s (inverse-time characteristics) at surrounding air temperature of 50°C

Further Enhanced PID Control

PID multiple loops (two loops)

Two PID operation units are available in the inverter. The inverter can perform PID control of the motor operation and control the external equipment at the same time. The system cost can be reduced because no external PID controller is required for controlling the external equipment.

Direct setting of the PID set point

The PID set point can be set directly from the operation panel. The setting can be easily changed at hand.

PID pre-charge function

Before PID action, the water flow to the pipe is controlled by operating the motor at a constant speed until the measured value (pressure, etc.) reaches the set level. This function is used to avoid rapid acceleration/deceleration caused by starting the PID action while the pipe is empty, and prevent a water hammer action, etc.

Multi-pump function

By controlling the pumps connected in parallel (up to four pumps) by the PID control by one inverter, water volume, etc. can be adjusted.
One of the connected pumps is driven by the inverter. Other pumps are driven by commercial power supply. The number of pumps to be driven by commercial power supply is automatically adjusted according to the water volume.

PID input pressure control

In order to prevent air intake and cavitation inside the pump, the pump inlet pressure can be controlled so that there is no water shortage.

Operating Status Monitoring

Load characteristics measurement function

The speed/torque relationship is stored while no fault occurs. By comparing the present load status with the stored load characteristics, out-of-range warnings can be output if applicable.
Mechanical faults such as clogging of the filter or breakage of the belt can be easily detected, and maintenance is facilitated.

Smooth Restart

Keep Running during Flying Start Operation

Regeneration avoidance function

The operation frequency is automatically increased to prevent the regenerative overvoltage fault from occurring. This function is useful when a load is forcibly rotated by another fan in the duct.

• 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).
• 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 (when using an optional LCD operation panel (FR-LU08)).

Compatibility with Various Systems

Compatibility with various networks

It supports BACnet^® MS/TP as standard, as well as Mitsubishi inverter protocol and MODBUS^®RTU (binary) protocol.
Communication options are also available for major network protocols such as CC-Link, CC-Link IE Field Network, LONWORKS^®, FL remote, PROFIBUS-DP V0, and DeviceNet™.

Simplified external equipment

The CA-type inverters are available. For the CA type, the monitor output terminal FM/CA operates as terminal CA (analog current output 0 to 20 mA), not as terminal FM (pulse train output). An external converter is not required.
(The factory setting is different for the CA type and the FM type.)

Mechanical Resonance Suppression

Speed smoothing control

Vibration caused by mechanical resonance can be reduced.
(Enabled only under V/F control.)

Support for up to three types of options

Three types of plug-in options can be attached.
The functions of the inverter can be extended through network. For example, additional I/O terminals can be used.

Easy Setup & Operation

Streamlining the Startup Process

A USB host connecter (A type), which allows external device connections, has been added.
Parameters can be copied to commercial USB memory devices.

● With the sense of unity with other Mitsubishi FA products with common MELSOFT design and operability, the software is easy to use.

● Easy plug-and-play connection is available to the USB terminal equipped as standard.

● A free trial version, which contains start-up functions, is available. It can be downloaded at Mitsubishi Electric FA Global Website.

Spring clamp terminals have been adopted for control circuit terminals.
Wires can be protected against loosening under vibrations during transportation of the inverter. Ten additional terminals are used as compared to the FR-F700(P) series.
Round crimping terminals can also be used by employing a control terminal option (FR-A8TR).

Easy-to-follow Display Improves the Operability

With the parameter setting mode selection of the operation panel, the group parameter mode can be selected to provide intuitive and simple parameter settings. (The conventional parameter setting mode is selected by default.)

To Aid with Maintenance

Reduced wiring check time

Serial number reading is possible using the optional LCD operation panel (FR-LU08) or the inverter setup software (FR Configurator2). Administration of different inverters has become much more simple.

Compact inverter for fans and pumps
Both the general-purpose motor and the IPM motor can be operated. The general-purpose motor driving setting can be switched to IPM driving setting by only one setting.
When the budget is limited, equipment investment can be made in several stages. Use this inverter with a general-purpose motor at first, then with an IPM motor.
