Guideline for Suppressing Harmonics in Home Electric and General-purpose Appliances

Our three-phase, 200 V class series inverters of 3.7 kW or less (FRENIC-Mini series) were the products of which were restricted by the "Guideline for Suppressing Harmonics in Home Electric and General-purpose Appliances" (established in September 1994 and revised in October 1999) issued by the Ministry of Economy, Trade and Industry.

The above restriction, however, was lifted when the Guideline was revised in January 2004. Since then, the inverter makers have individually imposed voluntary restrictions on the harmonics of their products.

We, as before, recommend that you connect a reactor (for suppressing harmonics) to your inverter. As a reactor, select a "DC REACTOR" introduced in this manual. For use of the other reactor, please inquire of us about detailed specifications.

Japanese Guideline for Suppressing Harmonics by Customers Receiving High Voltage or Special High Voltage

Refer to this manual, Appendix B for details on this guideline.

 Precautions for Use

Driving a 400 V general-purpose motor

Torque characteristics and temperature rise

In running generalpurpose motors

Vibration

Noise

When driving a 400 V general-purpose motor with an inverter using extremely long wires, damage to the insulation of the motor may occur. Use an output circuit filter (OFL) if necessary after checking with the motor manufacturer. Fuji motors do not require the use of output circuit filters because of their reinforced insulation.

When the inverter is used to run a general-purpose motor, the temperature of the motor becomes higher than when it is operated using a commercial power supply. In the low-speed range, the cooling effect will be weakened, so decrease the output torque of the motor. If constant torque is required in the low-speed range, use a Fuji inverter motor or a motor equipped with an externally powered ventilating fan.

When an inverter-drive n m otor i s m ounte d to a m achine, resona nce m ay be caused by the natural frequencies of the machine system.

Note that operation of a 2-pole motor at 60 Hz or higher may cause abnormal vibration.

* The use of a rubber coupling or vibration-proof rubber is recommended. * Use the inverter's jump frequency control feature to skip the resonance

frequency zone(s).

When an inverter is used with a general-purpose motor, the motor noise level is higher than that with a commercial power supply. To reduce noise, raise carrier frequency of the inverter. Operation at 60 Hz or higher can als o result in higher level of wind roaring sound.

In running special motors

High-speed motors

Explosion-proof motors

Submersible motors and pumps

Brake motors

Geared motors

Single-phase motors

If the reference frequency is set to 120 Hz or more to drive a high-speed motor, test-run the combination of the inverter and motor beforehand to check for safe operation.

When driving an explosion-proof motor with an inverter, use a combination of a motor and an inverter that has been approved in advance.

These motors have a higher rated current than general-purpose motors. Select an inverter whose rated output current is higher than that of the motor.

These motors differ from general-purpose motors in thermal characteristics. Set a low value in the thermal time constant of the motor when setting the electronic thermal overcurrent protection (for motor).

For motors equipped with parallel-connected brakes, their power supply for brake must be supplied from the inverter’s primary circuit. If the power supply for brake is connected to the inverter's output circuit by mistake, the brake will not work.

Do not use inverters for driving motors with series-connected brake coils. If the power transmission mechanism uses an oil-lubricated gearbox or

speed changer/reducer, then continuous motor operation at low speed may cause poor lubrication. Avoid such operation.

Single-phase motors are not suitable for inverter-driven variable speed operation. Use three-phase motors.

Environmental conditions

Installation location

Use the inverter within the ambient temperature range from -10 to +50°C. The heat sink and braking resistor of the inverter may become hot under

certain operating conditions, so install the inverter on nonflammable material such as metal.

Ensure that the installation location meets the environmental conditions specified in Chapter 8, Section 8.4 "Operating Environment and Storage Environment."

iii

Install a recommended molded case circuit breaker (MCCB) or Installing an MCCB or RCD/ELCB

residual-current-operated protective device (RCD)/earth leakage circuit

breaker (ELCB) (with overcurrent protection) in the primary circuit of each

inverter to protect the wiring. Ensure that the circuit breaker capacity is

equivalent to or lower than the recommended capacity.

If a magnetic contactor (MC) is installed i n the inverter's output (seconda ry) Installing an MC

in the secondary circuit

circuit for switching the motor to commercial power or for any other

purpose, ensure that both the inverter and the motor are completely stopped

before you turn the MC on or off.

Remove a surge killer integrated with the magnetic contactor in the

inverter's output (secondary) circuit.

Combination with peripheral devices

Installing an MC in the primary circuit

Protecting the motor

Discontinuance of power-factor correcting capacitor

Discontinuance of surge killer

Reducing noise

Do not turn the magnetic contactor (MC) in the primary circuit on or off

more than once an hour as an inverter failure may result.

If frequent starts or stops are required during motor operation, use terminal

[FWD]/[REV] signals or the

key.

The electronic thermal feature of the inverter can protect the motor. The

operation level and the motor type (general-purpose motor, inverter motor)

should be set. For high-speed motors or water-cooled motors, set a small

value for the thermal time constant.

If you connect the motor thermal relay to the motor with a long wire, a

high-frequency current may flow into the wiring stray capacitance. This

may cause the thermal relay to trip at a current lower than the set value. If

this happens, lower the carrier frequency or use the output circuit filter

(OFL).

Do not connect power-factor correcting capacitors to the inverter’s primary

circuit. (Use the DC reactor to improve the inverter power factor.) Do not

use power-factor correcting capacitors in the inverter’s output (secondary)

circuit. An overcurrent trip will occur, disabling motor operation.

Do not connect a surge killer to the inverter's output (secondary) circuit.

Use of a filter and shielded wires is typically recommended to satisfy EMC

Directive.

Refer to Appendices, App. A "Advantageous Use of Inverters (Notes on

electrical noise)" for details.

If an overvoltage trip occurs while the inverter is stopped or operated under

Measures against surge currents

light load, it is assumed that the surge current is generated by open/close of

the phase-advancing capacitor in the power system.

* Connect a DC reactor to the inverter.

When checking the insulation resistance of the inverter, use a 500 V megger

Megger test

and follow the instructions contained in the FRENIC-Mini Instruction

Manual (INR-SI47-1729-E), Chapt er 7, Section 7.5 "Insulation Test."

Wiring

Control circuit wiring length

Wiring length between inverter and motor

Wire size

When using remote control, limit the wiring length between the inverter and

operator panel to 20 m or less and use twisted pair or shielded wire.

If long wiring is used between the inverter and the motor, the inverter may

overheat or trip due to overcurrent because a higher harmonics current

flows into the stray capacitance between each phase wire. Ensure that the

wiring is shorter than 50 m. If this length must be exceeded, lower the

carrier frequency or install an output circuit filter (OFL).

Select wires with a sufficient capacity by referring to the current value or

recommended wire size.

Selecting inverter capacity

Transportation and storage

Wire type

Do not share one multi-core cable in order to connect several inverters with

motors.

Grounding Securely ground the inverter using the grounding terminal.

Select an inverter according to the nominal applied motor ratings listed in

Driving general-purpose motor

the standard specifications table for the inverter.

When high starting torque is required or quick acceleration or deceleration

is required, select an inverter with one rank larger capacity than the

standard. Refer to Chapter 7, Section 7.1 "Selecting Motors and Inverters"

for details.

Driving special motors

Select an inverter that meets the following condition:

Inverter rated current > Motor rated current

For transportation and storage instructions, see the FRENIC-Mini Instruction Manual (INR-SI47-1729-E), Chapter 1, Section 1.3 "Transportation" and Section 1.4 "Storage Environment."

1.1 Features.......................................................................................................................................................1-1

1.2 Control System..........................................................................................................................................1-10

1.3 Recommended Configuration................................................................................................................... 1-11

1.1 Features

Upgraded FRENIC-Mini (FRNC2-) functions

• Dynamic torque vector control providing bumped-up torque performance

Fuji's original dynamic torque vector control broadens the range of applications.

• RS-485 communications port provided as standard to facilitate system configuration

While the original FRENIC-Mini series has an RS-485 communications port as an option, the upgraded one has it as standard, making it easy to connect the upgraded one to a PLC and facilitating system configuration.

• Slow flowrate stop function under PID control for further energy saving

Under PID control for constant pump discharge pressure, the slow flowrate stop function stops the inverter when the pump discharge pressure is high, which achieves further energy saving.

• Braking signal function making the FRENIC-Mini applicable to simple vertical lift applications

The upgraded FRENIC-Mini series supports brake ON/O FF signals that are conventi onally su pported by the upper inverter series only. The braking signal fun ction enables t he FRENIC-Mini to be applied to simple vertical lift applications.

• Motor switching function

Turning the Di terminal ON and OFF switches between parameters specified for the 1st motor and those for the 2nd motor. This further broadens the range of applications.

1.1 Features

Chap. 1 INTRODUCTION TO FRENIC-Mini

• Motor auto-tuning

The auto-tuning function enables the dynamic torque vector control, automatic energy saving operation, and other advanced motor controls to be applied also to non-Fuji general purpose motors.

• Long-life DC link bus capacitors, control printed circuit board capacitors and cooling fans adopted

• Optional USB-equipped remote keypad

Data copying and connection to FRENIC Loader are easy.

• Permanent magnet synchronous motor (PMSM) supported

A PMSM is more efficient than an induction motor (IM) so that further energy saving c an be achieved.

• Available capacity range up to 15 kW (20 HP)

The capacity range has been spread.

1-1

Optimum performance for traversing conveyors

• High starting torque, at 150% or more

Equipped with Fuji's original dynamic torque-vector control system and the automatic torque boost function, these inverters ensure consistent and powerful operation (when automatic torque boost and slip compensation control are ON and start frequency is set at 3 Hz).

Figure 1.1 Torque Characteristics Data

(Dynamic torque vector control: ON)

Figure 1.2 Example of Output Torque Characteristics

• Braking resistor connectable to the inverter

FRENIC-Mini series of inverters features a built-in braking transistor (for inverters of 0.4 kW (1/2 HP) or larger), which makes it possible for an opt ional braki ng resistor to be connecte d to increase t he regenerative braking ability for conveya nce and transpor tation machin ery that req uires stro ng braking power.

• Trip-free operation

The remarkably improved current limiting function (stall prevention) ensures trip-free operation even for impact loads.

Figure 1.3 Example of Response for Impact Load Torque

• Stable operation even for a step load

The slip compensation function ensures stable operation even when the motor load fluctuates (step load).

Figure 1.4 Example of Response for Step Load Torque (Refer to the note in Figure 1.2 for the test configuration.)

• Inclusion of a brake signal makes it even more convenient

At brake release time After the motor runs, the inverter detects torque generation and outputs signals.

1.1 Features

Chap. 1 INTRODUCTION TO FRENIC-Mini

At brake application time Brake application that matches the timing can be done, so mechanical brake wear is reduced.

• Tripless deceleration by automatic deceleration control

The inverter controls the energy level generated and the deceleration time to decelerate to stop the motor without tripping due to overvoltage.

Figure 1.5

Default functions for fans and pumps

• Automatic energy-saving function provided as standard

To minimize the total loss (motor loss plus inverter loss), rather than just the motor loss as in the predecessor models, FRENIC-Mini saves even more power when used with fans or pumps.

Refer to Chapter 4, Section 4.7 "Drive Command Controller" for details.

• PID control function

Permits motor operation while controlling temperature, pressure, or flow rate without using an external device such as a temperature regulator. Under the constant pump discharge pressure control, the slow flowrate stop function is available.

Refer to Chapter 4, Section 4.8 "PID Frequency Command Generator" for details.



• Cooling fan ON/OFF control function

The inverter's cooling fan can be turned off while the fan or pump is stopped for noise reduction and energy savings.

The ideal functions to serve a multiplicity of needs for small-capacity inverters

• Compatible with a wide range of frequency settings

You can select the optimum frequency setti ng method that m atches your m achine or equipm ent via the

keypad ( 1 to 5 V), 16 multistep speed settings (0 to 15 steps) or via RS-485 communications.

• A transistor output is provided

This enables an overload early warning, lifetime forecast or other information signals to be output during operation.

Refer to function code E20 in Chapter 9, Section 9.2.2 " E codes (Extension terminal functio ns)."



• High output frequency - up to 400 Hz

The inverter can be used with equipment such as centrifugal separators that require a high motor speed. In this case, you need to check whether the machine operation in combination with the motor is compatible or not.

• Three points can be set for a non-linear V/f pattern.

The addition of an extra point (total 3 points) for the non-linear V/f pattern, which ca n be set as desired, improves the FRENIC-Mini's drive capability, because the V/f pattern can be adjusted to match a wider application area.

Refer to Chapter 4, Section 4.7 "Drive Command Controller" for details.

1.2 Control System

This section gives you a general overview of inverter control systems and features specific to the FRENIC-Mini series of inverters.

As shown in Figure 1.8, single- or three-phase commercial power is converted to DC power in the converter section, which is then used to charge the capacitor on the DC link bus. Accor ding to co ntrol commands or signals generated in the control logic, the inverter modulates the electricity charged in the capacitor to PWM (Pulse Width Modulation) format and feeds the output to the motor. The modulation frequency is called "carrier frequency." As shown in Figure 1.7, the voltage waveform of the modulated power source produces pulse train with positive and negative polarity synchronized with the inverter's output comm and frequ e ncy . The inverter feeds the produced output as drive power with sinusoidal current waveform like that of ordinary commercial power lines.

PWM voltage waveform Current waveform

Figure 1.7 Output Voltage and Current Waveform of the Inverter

For the reference frequency given in the control logic, the accelerator/decelerator pr ocessor calculate s the acceleration/deceleration rate required by run/stop control of the m otor and transfers the calc ulated results to the 3-phase voltage command processor directly or via the V/f pattern generator.

Refer to Chapter 4, Section 4.7 "Drive Command Controller" for details.



The FRENIC-Mini series changes the voltage control from the "Simplified Torque-Vector Control" using a magnetic flux estimator in conventiona l inverter series, to the Dynam ic Torque Vector Control adopted in upper inverter series. Accordingly, the FRENIC-Mini series assures high start torque that the conventional series cannot obtain, broadening the range of applications.

The control logic section, which is the very brain of the invert er, allows you to customize the i nverter's driving patterns using the function code settings.

 Displaying I/O signal status in hexadecimal format

Each I/O terminal is assigned to bit 15 through bit 0 as listed in Table 3.11. An unassigned bit is interpreted as "0." Allocated bit data is displayed on the LED monitor in 4-digit hexadecimals ("0" to "F" each).

With the FRENIC-Mini, digital input terminals [FWD] and [REV] are assigned to bit 0 and bit 1, respectively. Terminals [X1] through [X3] are assigned to bits 2 through 4. The value "1" is set for each bit when the assigned input terminal is short-circuited (ON) with terminal [CM]. The value "0" when it opens (OFF). For example, when [FWD] and [X1] are ON and all others are OFF, the display on LED4 to LED1 would be 0005.

Bit 0 is assigned to digital output terminal [Y1]. The value "1" is set when the terminal is short-circuited with [Y1E], and the value "0" is set when it opens. The status of the mechanical relay contact output terminal [30A], [30B] and [30C] are assigned to bit 8. The value "1" is set when the circuit between output terminals [30A] and [30C] is clos ed and the value "0" when the circuit between [30B] and [30C] is closed. For example, if [Y1] is ON and the circuit between [30A] and [30C] are short-circuited with each other, then the display for LED4 to LED1 would be 0101.

4.1 Symbols Used in the Block Diagrams and their Meanings

FRENIC-Mini inverters are equipped with a num ber of function codes to m atch a variety of m otor operations required in your system. Refer to Chapter 9 "FUNCTION CODES" for details of the function codes.

The function codes have functional relationship with each other. Several special function codes also work with execution priority with each other depending upon their data settings.

This chapter contains the main block diagr am s for contr ol l ogic i n the i nverter a nd de scribes th e relati onship between the inverter's logic and fun ction c odes. It is im portant to fu lly u nderstand this relationshi p a nd to set the function code data correctly.

The block diagrams contained in the chapter show only function codes having mutual relation. For the function codes that work stand-alone and for details of individual function codes, refer to Chapter 9 "FUNCTION CODES."

4.2 Drive Frequency Command Generator

Figure 4.1 shows the processes that generate the final drive frequency command from the frequency settings given by various means and those switched/modified by function codes. If PID process control takes effect (J01=1 or 2), the drive frequency generation will differ from that shown in this diagram. (Refer to Section 4.8 "PID Frequency Command Generator.")

Additional and supplemental information is given below.

- Frequency settings using the

key on the keypad may take a different format by means of the data

setting for function code E48. Refer to function code E48 in Chapter 9 "FUNCTION CODES" for details.

- [C1] input as a frequency settings signal will always be interpreted as "0" when the current input signal

terminal [C1] is specified for the thermistor (H26 = 1, 2).

- Settings for both gain and bias will take effect concurrently only for frequency setting 1 (F01). For

frequency setting 2 (C30) and auxiliary frequency settings 1 and 2 (E60 to E62), only the gain will take effect.

- Gain for the built-in potentiometer cannot be changed by any function code or other means.

- Switching between normal and inverse operation is only effective for frequency setting from the analog

input signal (terminal [12], [C1] or built-in potentiometer). Frequency settings from the

key are

only valid for normal operation.

- The command formats for frequency settings by S01 and S05 for the communications link facility take a

different form, as follows:

- S01: the setting range is –32768 to +32767, where the maximum output frequency is obtained at ±20000.

- S05: the setting range is 0.00 to 655.35 Hz in 0.01 Hz step, or 0.1 Hz step for the maximum frequency exceeding 600 Hz.

- Priority level for setting for S01 is higher than that for S05. If a value other than 0 is set for S01, then the data set to S01 will take effect. If S01 = 0, the setting for S05 will take effect.

4.3 Drive Command Generator

The drive command generator shown in Figure 4.2 produces final drive comm ands (FWD: Drive the motor i n the forward direction) and (REV: Drive the motor in reverse direction) from the r un commands that are given by various means and modified/switched by function codes.

Additional and supplemental information is given below.

- For the run command given by the the

key and releases it upon depression of the key except during jogging operation.

key, the generator holds the command ON upon depression of

- The hold command HLD holds the run forward/reverse commands FWD/REV until it is turned OFF. This allows you to run the inverter in "3-Wire Operation." Refer to the function code E01 in Chapter 9 "FUNCTION CODES" for details.

If you do not assign a hold command HLD to any digital input terminals, then the "2-Wire Operation"

using the FWD and REV command will be active.

- Setting 0 (zero) for function code F02 allows you to operate the inverter using the

key on the

built-in keypad for the run command, while the FWD and REV commands determine direction of motor rotation. The logic shown in the block diagram shows you that if the run command from the

key and

either the FWD or REV command are given, then the internal run command <FWD> or <REV> decode d internally by the logic turns ON.

- S06 (2-byte data for bit 15 through bit 0 can be manipulated), the operation command by the communications link, includes:

- Bit 0: assigned to FWD

- Bit 1: assigned to REV

- Bits 13 and 14: programmable bits equivalent to the terminal inputs [FWD] and [REV]

- In the block diagram, all of these are noted as operation commands. The data setting for function co d e E98 to specify the terminal signal property for [FWD] and E99 for [REV] determine which bit value should be selected as the run command. If bits 13 and 14 hav e th e same setting to specify the property for (FWD) or (REV), the output of bit 13-14 processor logic will follow the truth table list ed in Fig ure

4.2.

- If either one of bits 13 and 14 is ON (1 as logic value), the OR logic will make the link command LE turn ON.

- If both run commands FWD and REV come ON concurrently, the logic forces the internal run commands

<FWD> and <REV> to immediately turn OFF.

- If you set 1 or 3 to function code H96 (STOP key priority/Start Check) to make the

key priority effective, then depressing the key forces the internal run commands <FWD> and <REV> to immediately turn OFF.

- If you have enabled operat io n via the timer, inputting any run command starts the timer. The internal run

command <FWD> or <REV> and hold command HLD triggered by key pad will be aut om atically turned OFF after the time preset in the timer has elapsed.

Chap. 4 BLOCK DIAGRAMS FOR CONTROL LOGIC

- If the reference frequency is lower than the start frequency (F23) or the stop frequency (F25), the internal run commands will remain OFF.

4.4 Terminal Command Decoders

Programmable digital input terminals [X1], [X2], [X3], [FWD] and [REV] can be assigned to internal terminal commands such as FWD or REV decoded by data settin gs of related fu nction codes as shown in the block diagrams in Figures 4.3 (a) through 4.3 (d). In the decoders, negative logic input signals are also applicable if you set data of 1000s to the function code.

The contents of the block diagram are div ided into five gr oups, dependi ng on whether inputs are assigne d for the same internal terminal comm ands respectively or t he commands iss ued from the comm unications facility (linked operation) specify the internal commands. Each of the diagrams shown in Figure 4.3 has following role.

- Figure 4.3 (a) The terminal command decoder (general) shows the decoding process of the internal commands functioning with the negative l ogic inputs. T his is switchab le with inputs from the communications facility (for example, link operation commands received through RS-485 communications).

- Figure 4.3 (b) The terminal command decoder (terminal signal inputs) shows the process to decode internal terminal commands de dica ted to the con trol si gnal in put applie d to the in verter 's terminal block. These commands cannot be changed via the com munications facility (link operation command).

- Figure 4.3 (c) The terminal command decoder (terminal signal input excluding negative logic) shows process to produce FWD and REV commands. In this process, settings via the communications facility do not take effect. In the next process of the drive command generator, however, they may take effect. (Refer to the block diagram in Section 4.3, "Drive Command Generator.") To keep the inverter operation safe, any negative logic input for the FWD and REV commands cannot be applied.

- Figure 4.3 (d) The upper part of the terminal command decoder (ORing with link commands/ignoring link commands) shows the process to produce commands by ORing signals issued from the communications facility and the control sign al input term inal bl ock (Logical Orin g. If any of input signals is ON, then the command becomes ON.).

The lower part of the terminal command decoder shows the control in which only digital

inputs of all control signals are enabled even if link operation command LE has been turned ON.

4.7 Drive Command Controller

The simplified block diagram shown in Figure 4.6 explains t he process in which the inverter drives the m otor according to the internal run command <FWD>/<REV> from the frequency genera tor, or the PID freque ncy command from the PID controller, and the run commands.

Additional and supplemental information is given below.

- The logic shown in the left part of the block diagram processes the drive frequency command so as to invert (×(-1)) the command for reverse rotation of the motor or to replace it with 0 (zero) for stopping the motor.

- The accelerator/decelerator processor determines the output frequency of the inverter by referring to the set data of related function codes. If the output frequency exceeds the peak frequency given by function code F15, the controller limits the output frequency at the peak.

- Acceleration/deceleration time is selectable from acceleration/deceleration time 1 or 2, or acceleration/deceleration time for jogging operation. The suppression of the regenerative braking feature may multiply the commanded acceleration/deceleration time by 3. Refer to role of function code H69 in the block diagram.

- If the overload prevention control feature is active, then the logic automatically switches the output frequency to one of overload suppression control and controls the inverter using the switched frequency.

However, if the current limit control is active (F43 ≠ 30, H12 = 1), the overload prevention control

automatically becomes inactive.

- If the current limit control is active, then the logic automatically switches the output frequency to one of current limit control and controls inverter using the switched frequency.

- The slip compensation facility adds frequency components based on the preset rated slip frequency (P12) to the frequency currently commanded. The logic adjusts the error according to the settings of the slip compensation gain for driving (P09) and braking (P11).

the set data of function code P09 that controls slip compensation gain for the motor.

- The voltage processor determines the output voltage of the inverter. The processor adjusts the output voltage to control the motor output torque.

- If DC braking control is active, the logic switches the voltage and frequency control components to ones determined by the DC braking block to feed the proper power to the motor for DC braking.

4.8 PID Frequency Command Generator

The block diagram shown in Figure 4.7 shows the PID frequency command generator that becomes active when the PID control is enabled (J01= 1 or 2). The logic shown generates the final frequency command according to the PID process command given by various means of setting and feedback, or frequency settings as a speed command given manually, and various means of switching.

Additional and supplemental information is given below.

- Switching of data settings for frequency 2 (C30), auxiliary frequencies 1 and 2 (E60 to E62) as manual speed commands will be disabled.

- For multistep frequency settings, settings 1 to 3 are exclusively applicable to the manual PID speed command.

- For selecting analog input (terminal [12], [C1], or built-i n POT) as the PID process comm and, you need to set proper data for function codes E60 to E62 and J02.

- Multistep frequencies that can be used as a PID process command include multistep frequency 4 (C08), 8 (C12) and 12 (C16).

- To switch the operation between normal and inverse, the logic inverses polarity of deviation between the PID command and its feedback (turning INV command ON/OFF, or setting J01 = 1 or 2).

- Refer to Section 4.2 " Drive Frequency Command Generator" for explanations of common items.

5.1 Overview on RS-485 Communication

Using the RS-485 communications port on the FRENIC-Mini series enables the following extended functions.

 Operation from a remote keypad

Connecting a remote keypad to the RS-485 communications port on the inverter with an extension cable allows you to mount the keypad on the easy-to-access front of a panel. The maximum length of the extension cable is 20 m (66 ft.).

 Operation by FRENIC Loader

The FRENIC-Mini can be connected to a Windows-based PC, on whi ch you can run FREN IC Loader (see Section 5.2 "Overview of FRENIC Loader.") to edit the function code data and monitor the running status information of the inverter.

 Operation from the host equipment

The FRENIC-Mini can be connected to host equipment (m aster) such as a PLC or com puter. It can act as a slave device.

Protocols for managing a network inclu ding inverters include t he Modbus RTU protocol (compliant to the protocol established by Modicon Inc.) that is widely used in FA markets and the Fuji general-purpose protocol that supports the FRENIC-Mini and conventional series of inverters.

Chap. 5 RUNNING THROUGH RS-485 COMMUNICATIONS

For the remote keypad, the inverter uses the dedicated protocol that automatically switches the operation source to the remote keypad, so no function code setting is required.

For FRENIC loader, however, you need to set up function code H30 for some communications conditions although the dedic ated protocol is used.

For the details about the termi nating resistor swit ch, refer to the FRENIC-Min i Instruction Manual, Section 2.3.7 "Setting up the slide switches."

When connecting a remote keypad, it is no t ne cessary t o turn th e terminating resistor switch ON.

5-3

5.1.3 Connection

You need to select devices suitable for your network configuration, referring to the figure shown below.

Converter Some computers are not equipped with an RS-485 communications port but with a USB port, so a

USB/RS-485 converter is required to connect them to the RS-485 communications p ort on the inverter. It is recommended that insulated converters such as RS-485/RS-485 converters be used for eliminating electric noise.

Multi-drop branch connector The RS-485 communications port on the FRENIC-Mini uses an RJ-45 connector. For multi-drop

connection of inverters, therefore, multi-drop branch connectors (MS8-BA-JJJ by SK Koki Co.) are required.

Cable For the connection of the remote keypad, use an 8-wire straight cable with an RJ-45 connector.

(Remote keypad extension cable option: CB-5S) For the connection of other equipment or connection of FRENIC-Mini inverters with each other, us e a

cable that has signal wires only. (EIA568-compliant 10BASE-T)

- No converter is required for connection of the remote keypad.

- To connect the FVR-E11S series of general-purpose inverters to the FRENIC-Mini series, take necessary measures for the difference of the pin assignment between FVR-E11S and FRENIC-Mini series to avoid a short-circuited failure.
