Enhanced Energy Savings

Optimizing Energy-Savings for the complete system

In addition to optimizing the control of the applied motor for Energy-Savings, FRENICEco series drives also optimizes power consumption of the drive for maximizing EnergySavings for the complete system. With regulations expected to call for a reduction of 1% or more in annual energy consumption, Fuji Electric is aiming to optimize energysavings as a complete system approach and not focusing only on reducing energy consumed by the motor.

Using this new system, energy savings is several percent improved over that of the previous models.

Kyoto Agreement, which was studied at the Conference on Prevention of Global Warming (COP3), was ratified by Russia in October 2004, and thereby put into effect on February 16,

2005. In the future, the related regulations are calling for a reduction in energy consumption of 1% or more each succeeding year, and therefore, we are aiming to build energy saving features into equipment as a whole.

FRENIC-Eco is the inverter equipped with

the industry's highest level of efficiency (low power loss).

Number of starts

Example of Use

The number of times the equipment is started and stopped is recorded, so this can be used as a criterion for replacing parts in equipment where starting and stopping is a burden on the machine.

Equipped with the optimum functions for HVAC (Air conditioning systems)

Operation is continued even after the momentary power failure thanks to the auto-restart function.

Even if a momentary power failure occurs, load inertia of a fan or blower, etc. is used to maintain the motor's operation while the motor's operating speed gradually drops, and enables the motor to restart operation without stopping. (The motor may stop on occasion due to the load's inertia.)

Even greater energy savings through the low water volume stop function

When there is pump operation accompanying "pressure drop" that occurs due to pressure loss or leakage, etc. in the piping, etc., or at times when the pump runs repeatedly to obtain a small volume of water, this function controls the pump's operation, preventing it from being driven with the water volume below a predetermined level, and thus reducing wasteful pump operation and saving even more energy.

The equipment's operating condition is determined by the low torque detection function.

The inverter determines the load state of the connected motor and if it drops below a predetermined level, it judges that a "Low Torque" state exists and outputs a signal to that effect. In this way, any trouble that occurs in the equipment (such as a belt on a pulley breaking) can be detected by the inverter.

Also avoids operation signal trouble through the command loss detection function.

If the frequency signals (0 to 10V, 4 to 20mA, multi-step speed operation signals, communications, etc.) that are connected to the inverter are lost, signals are output as a "command loss," indicating that a frequency command was lost. In addition, output frequency when the command loss occurred can be set in advance, so even if a frequency signal line to equipment is broken due to machine vibration, etc., machine operation can be continued uninterrupted.

Simple circuit configuration using the commercial line switching sequence

Continuous equipment operation through overload avoidance control

Inverters are equipped with the commercial line start function that enables switching between the commercial line and the inverter by an external sequence. In addition, inverters are equipped with two types of built-in sequence for operation with commercial line; i.e., Fuji's standard sequence and the automatic switching

If the load on a fan or pulley increases due some foreign object overloading around the shaft, etc., and the inverter's internal temperature rises suddenly or the ambient temperature rises to an abnormal level, etc., causing an inverter overload state, the motor's speed is lowered, reducing the load and enabling operation to continue.

sequence to the commercial line activated when the inverter alarm occurs.

Note: The latter sequence differs from the one for forcible switching to the commercial line during inverter breakdown.

Load state

Inverters are equipped with full PID control functions.

Low water level stop function, deviation alarm and absolute value alarm outputs have been added to the PID regulator which performs such tasks as temperature, pressure and flow rate control. In addition, an anti-reset windup function that prevents PID control overshoot as well as a PID output limiter and integral hold/reset signal provide easy-to-adjust PID control functions.

Simple Sequences through Universal DI/DO

Signals can be transmitted to a higher level controller or PC by connecting digital signals to an inverter from different types of sensors, such as a float switch used to judge the level in a water storage tank, which serve as peripheral devices to the inverter. In the case of small-scale equipment, even if a programmable logic controller (PLC) is not used, information can be sent to a higher-level system easily.

Improved capability for handling regenerated energy

When the inverter slows down and stops the motor, if the braking energy regenerated by the motor exceeds the braking capacity of the inverter's main circuit capacitor, the inverter will trip. At such a time, if even a little excess energy trips the inverter, using this function you may be able to absorb the excess braking energy without connecting to a braking resistor.

Dynamic Rotation of Pump Motors

●With a fixed inverter-driven motor

This configuration consists of a motor driven by the inverter (M0) and motors driven by commercial power (M1 to M4). The inverter-driven motor is fixed at M0 and is controlled for variable speed. When the inverter-driven motor M0 alone cannot sustain the desired discharge flowrate, the inverter starts one or more motors driven by commercial power as necessary.

Consideration of the surrounding environment and panel design

Side-by-side installation saves space!

If multiple inverter units are to be used in a panel and the panel is designed accordingly, it is possible to mount these inverters side-byside horizontally, so the panel can be designed to take up less space. (5HP for 208V,7.5HP for 460V or smaller capacity inverters)

Built-in charging resistors (in rush current suppressing resistors) help reduce peripheral equipment sizing!

When the FRENIC-Eco series (Fuji's FRENIC-Mini Series and 11 Series) is used, the charging resistors (in rush current suppressing resistors) built into the inverter as standard equipment suppress in rush current when motors are started, so compared to operation of motors with direct input, peripheral equipment with reduced capacity can be selected.

Cooling outside the panel is made possible by an external cooling attachment!

Use of the external cooling attachment (optional on 30HP for 208V, 40HP for 460V or smaller inverters and standard on 40HP for 208V, 50HP for 460V or larger inverters) to cool the inverter outside the panel makes it possible to install a simple cooling system outside the panel.

Energy Savings with an Inverter

How does using an inverter save me energy?

●

If you run a fan or pump and you have damper (valve) control or control it with an inverter, the relation between the air flow (flow rate) and the required power, as well as the relation between the power supply frequency fs (Hz) and operating frequency with the inverter fINV (Hz) are as shown in the table at right.

●

If the air flow rate is low, the energy saving effect is particularly great.

For example, if air flow Q: 60 (%) = Power supply frequency fs: 50 (Hz) Q (%) = f 60 (%) = frun (Hz) / 50 (Hz) → frun (Hz) = 50 (Hz) x 0.6 = 30 (Hz)

Energy Savings effect of replacing damper (valve) control with inverter control

Example: The energy savings effect on an office's air conditioning equipment if the operating pattern is as follows: Air flow: 85% for 2,000 hrs, and 60% for 2,000 hrs.Total 4,000 hrs/year. Motor output is 15kW x 1 unit.

Under damper (valve) control,

(15kW x 91% x 2,000 hrs.) + (15kW x 76% x 2,000 hrs.) =

If an inverter is used

Rated capacity is calculated by assuming the output rated voltage as 208V for three-phase 208V.

Output voltage cannot exceed the power supply voltage.

An excessively low setting of the carrier frequency may result in the higher motor temperature or tripping of the inverter by its overcurrent limiter setting. Lower the continuous load or maximum load

* instead. (When setting the carrier frequency (F26) to 1kHz, reduce the load to 80% of its rating.)

Use [R1,T1] terminals for driving AC cooling fans of an inverter powered by the DC link bus, such as by a high power factor PWM converter. (In ordinary operation, the terminals are not used.)

Calculated under Fuji-specified conditions.

Obtained when a DC reactor (DCR) is used.
