(6) Disposal

 Before starting the operation, each parameter must be

confirmed and adjusted. A failure to do so may cause some machines to make unexpected motions.

 Before starting the operation, the wiring of each

peripheral device must be checked. Faulty wiring may cause some machines to make unexpected motions.

(3) Usage

 Any person must stay away from the equipment when the

retry function is set as it will restart suddenly after a trip.

 Since pressing the key may not stop the operation

depending on the function setting status, separate circuit and switch that make an emergency stop (power OFF, etc.) must be provided.

 OFF status of the inverter start signal must be confirmed

before resetting a fault of the converter. If reset is performed with the start signal ON, the converter starts suddenly.

 The load must be always inverters. Connection of any

other electrical equipment to the converter output may damage the equipment.

 Do not modify the equipment.  Do not perform parts removal which is not instructed in

this manual. Doing so may lead to fault or damage of the product.

 The converter must be treated as industrial waste.

(7) General instruction

Many of the diagrams and drawings in this Instruction

Manual show the converter without a cover or partially open

for explanation. Never operate the converter in this manner.

The cover must be always reinstalled and the instruction in

this Instruction Manual must be followed when operating

the converter.

 Do not use a magnetic contactor on the power input side

for frequent starting/stopping of the converter or the inverter. Otherwise the life of the converter or the inverter decreases.

 The effect of electromagnetic interference must be

reduced by using a noise filter or by other means. Otherwise the electronic equipment used near the converter or the inverter may be affected.

 When parameter clear or all parameter clear is performed,

the required parameters must be set again before starting operations because all parameters return to the initial value.

 Before running a converter or an inverter which had been

stored for a long period, inspection and test operation must be performed.



Static electricity in your body must be discharged before you touch the product. Otherwise the product may be damaged.

(4) Emergency stop



A safety backup such as an emergency brake must be provided to prevent hazardous condition to the machine and equipment in case of the converter and inverter failure.

 When the breaker, which is installed in the input side of

the converter, trips, the wiring must be checked for a fault (short circuit), and internal parts of the converter and the inverter for a damage, etc. The cause of the trip must be identified and removed before turning ON the power of the breaker.

 When any fault occurs, take an appropriate corrective

action, then reset the converter, and resume the operation.

(5) Maintenance, inspection and parts replacement

 Do not carry out a megger (insulation resistance) test on

the control circuit of the converter.

Pre-operation instructions

1.1 Pre-operation instructions

Incorrect handling may cause the equipment to operate improperly, its life to be reduced considerably, and in the worst case, the converter and inverter to be damaged. Please handle the unit properly in accordance with the information on each section as well as the precautions and instructions of this manual.

1.1.1 Features of FR-HC2 (high power factor converter)

Power supply harmonics generated from the converter part of an inverter may affect devices including a dynamo and a static capacitor. Power supply harmonics differ from noise and leakage current in their generating source, frequency range and transmission method. Power supply harmonic may be suppressed by using this converter, allowing the compliance with the harmonic suppression guideline issued by the former Japanese Ministry of International Trade and Industry (currently the Ministry of Economy, Trade and Industry). Conversion factor of the converter is K5=0 in the self-excitation three-phase bridge circuit.

REMARKS

Inverter parameters must be set. The parameter settings differ by the inverter series. Refer to page 55 for details.

NOTE

 When the load is light, harmonic suppression effect declines.  When the power supply voltage is unstable, harmonics from electric power system flow in, making the harmonic

current larger.

1.1.2 Japanese harmonic suppression guideline

Harmonic currents flow from the inverter to a power receiving point via a power transformer. The harmonic suppression guideline was established to protect other consumers from these outgoing harmonics. The all capacities and all models of the inverters used by the specific consumers became subject to the Harmonic Suppression Guideline for the Consumers Who Receive High-voltage or Special High-voltage (hereafter referred to as "Harmonic Suppression Guideline for Specific Consumers").

[Harmonic suppression guideline for specific consumers]

This guideline sets the maximum values of outgoing harmonic currents generated from a high-voltage or specially highvoltage consumer who will install, add or renew harmonic generating equipment. If any of the maximum values are exceeded, this guideline requires the consumer to take certain suppression measures.

(a) Calculation of equivalent capacity P0 of harmonic generating equipment

The "equivalent capacity" is the capacity of a 6-pulse converter converted from the capacity of a consumer's harmonic generating equipment and is calculated with the following equation. When the sum of equivalent capacity exceeds the limits in Table 3, harmonics must be calculated in the following procedure.

P0 =  (Ki Pi) [kVA]

Ki: Conversion factor(According to Table 2)

Pi: Rated capacity of harmonic generating equipment

 [kVA]

i : Number indicating the conversion circuit type

(b) Calculation of outgoing harmonic current

Outgoing harmonic current=fundamental wave current (value converted from received power voltage)

 Rated capacity: Rated capacity is determined by the capacity of the applied

motor and found in Table 5. It should be noted that the rated capacity used here

is used to calculate generated harmonic amount and is different from the power

supply capacity required for actual inverter drive.

Harmonic current is suppressed by installing an AC reactor (FR-HAL) in the AC input side of the inverter or a DC reactor (FR-HEL) in the DC bus line of the inverter, or by installing both.

FR-HC2 is designed to switch ON/OFF the converter circuit to convert an input current waveform into a sine wave, suppressing the harmonic current considerably. The converter (FR-HC2) is used with the standard-equipped peripheral devices and accessories.

Using the power factor improving static capacitor with a series reactor has an effect of absorbing harmonic currents.

Using two transformers with a phase angle difference of 30 as in - and provides an effect corresponding to 12 pulses and reduces low-degree harmonic currents.

A capacitor and a reactor are used together to reduce impedance at specific frequencies, producing a great effect of absorbing harmonic currents.

This filter detects the current of the circuit, where harmonic current is generated, and generates the harmonic current equivalent to the difference between that current and a fundamental wave current. By doing so, the harmonic current at where it was detected can be suppressed, and great absorption of harmonic current can be expected.

1.3 Precautions for selecting peripheral devices

1.3.1 Measures against noises (EMI)

In this section, noises indicate those of more than 40th to 50th high frequencies in a power distribution system, which

generally assume irregular conditions.

Some noises enter the converter to adversely affect it, and others are radiated by the converter to adversely affect peripheral

devices. Though the converter is designed to be immune to noises, it handles low-level signals, so it requires the following

basic measures. Also, since the converter chops input voltage at high carrier frequency, it could generate noises. If these

noises affect peripheral devices, measures should be taken to suppress noises (EMI measures). The EMI measures differ

slightly depending on the noise transmission paths.

(1) Basic measures

Do not place the power cables (I/O cables) and signal cables of the converter in parallel with each other and do not

bundle them.

For the control signal cable and the connection cable with a detector, use twisted pair shield cables, and connect the

sheath of the shielded cables to the terminal SD.

Ground (earth) the reactor 1, reactor 2, outside box, converter, etc. at one point. (Refer to page 53)

(2) Measures against noises which enter and affect the converter

When devices, which generate many noises, (for example, magnetic contactors, magnetic brakes, many relays) are

installed near the converter, the converter may malfunction because of the noises. In that case, the following measures

must be taken.

Provide surge suppressors for the devices that generate many noises, and suppress the noises.

Install data line filters to signal cables.

Ground (earth) the connection cable with a detector and a control signal cable with a metal cable clamp.

(3) Measures against the noises that are radiated by the converter to affect peripheral devices

Noises radiated by the converter are largely classified into three types: those radiated by the cables connected to the

converter and converter's main circuit (I/O), those electromagnetically and electrostatically inducted to the signal cables

of the peripheral devices close to the main circuit cable, and those transmitted through the power supply cables.

OUTLINE

Measures

When the devices, which handle low-level signals and are susceptible to noises (such as measuring

instruments, receivers and sensors), are installed near or in the same enclosure with the converter, or their

signal cables are placed near of in the same enclosure with the converter, the devices may malfunction due to

air-propagated electromagnetic noises. In that cases, following measures must be taken.

(1) Install the easily affected devices as far away from the converter and inverter as possible.

(2) Place the easily affected signal cables as far away from the converter and inverter as possible.

(3) Do not place the signal cables and power cables (converter I/O cables) in parallel with each other and do

not bundle them.

(4)Insert line noise filters ( FR-BLF, RC5128 (available product manufactured by Soshin Electric Co., Ltd.)) and

radio noise filters (FR-BIF) into the input side of the converter, and insert line noise filters (FR-BLF, RC5128

(available product manufactured by Soshin Electric Co., Ltd.)) into the output side of the inverter to

suppress cable-radiated noises.

(5) Use shield cables for signal cables and power cables and place them in individual metal conduits to

produce further effects.

When the signal cables are placed in parallel with or bundled with the power cables, magnetic and static

induction noises may be transmitted to the signal cables which causes the devices to malfunction. In that case,

the following measures must be taken.

(1) Install the easily affected devices as far away from the converter and inverter as possible.

(2) Place the easily affected signal cables as far away from the converter, inverter, and their I/O cables as

possible.

(3) Do not place the signal cables and power cables ( I/O cables of the converter and inverter) in parallel with

each other and do not bundle them.

(4) Use shield cables for signal cables and power cables and place them in individual metal conduits to

produce further effects.

When the peripheral devices are connected to the same power supply line with the converter, converter-

generated noises may flow back through the power supply cable to the devices, causing malfunction of the

devices. In that case, the following measures must be taken.

(1) Install radio noise filters (FR-BIF) to the power cable (input cable) of the converter.

(2) Install the line noise filters (FR-BLF, RC5128 (available product manufactured by Soshin Electric Co., Ltd.))

to the power cable (input cable) of the converter and to the power cable (output cable) of the inverter.

When a closed loop circuit is configured by connecting the wiring of a peripheral device to the converter,

leakage current may flow through the ground (earth) cable of the converter, causing malfunction of the device.

In that case, disconnecting the ground (earth) cable of the device may remove the malfunction.

NOTE

 Install the earth leakage circuit breaker (ELB) on the input side of the converter.

 In the connection earthed-neutral system, the sensitivity current is blunt against an earth (ground) fault in the

inverter output side. Earthing (Grounding) must conform with the requirements of national and local safety

regulations and electrical codes. (NEC section 250, IEC 536 class 1 and other applicable standards)

 When the breaker is installed on the output side of the inverter, it may be unnecessarily operated by harmonics even

if the effective value is less than the rating.

In this case, do not install the breaker since the eddy current and hysteresis loss will increase, leading to temperature

rise.

 The following models are the standard breakers

(2) Clearances around the converter

To ensure ease of heat radiation and maintenance, leave at least the shown clearance around the converter. At least the following clearance are required under the converter as a wiring space, and above the converter as a heat radiation space.

REMARKS

For replacing the cooling fan of the 160K or higher, 30cm of space is necessary in front of the inverter. Refer to page 141 for fan

replacement.

(3) Converter mounting orientation

Mount the converter on a wall as specified. Do not mount it horizontally or any other way.

(4) Above the converter

Heat is blown up from inside the converter by the small fan built in the unit. Any equipment placed above the converter should be heat resistant.

(5) Arrangement of multiple inverters and converters

When installing multiple inverters and converters in the same enclosure, generally arrange them horizontally as shown in the right figure (a). When it is inevitable to arrange them vertically to minimize space, take such measures as to provide guides since heat from the bottom converters can increase the temperatures in the top inverters, causing inverter failures.

When installing multiple inverters and converters, full caution must be taken not to let the surrounding air temperature of the converters and inverters exceed the permissible value. Avoid the temperature to exceed the value by providing ventilation and increasing the enclosure size, etc.

Arrangement of multiple inverters and converters

(6) Placement of ventilation fan and converter

Heat generated in the converter is blown up from the bottom of the unit as warm air by the cooling fan. When installing a ventilation fan for that heat, determine the place of ventilation fan installation after fully considering an air flow. (Air passes through areas of low resistance. Make an airway and airflow plates to expose the converter to cool air.)

Main circuit terminal specifications

2.6.3 Cable sizes of the main control circuit terminals and earth (ground) terminals

Select the recommended cable size to ensure that a voltage drop will be 2% max. If the wiring distance is long between the inverter and motor, a main circuit cable voltage drop will cause the motor torque to decrease especially at the output of a low frequency. The following table indicates a selection example for the wiring length of 20m

2.7 Wiring of main circuit (FR-HC2-7.5K to 75K, FR-HC2-H7.5K to H220K)

 Perform wiring securely to conform with the harmonic suppression guideline of the former Ministry of International

Trade and Industry (currently the Japanese Ministry of Economy, Trade and Industry). Incorrect wiring causes the converter to display an alarm or causes an fault or damage.

 Refer to the Instruction Manual of each inverter for the wiring of the inverter. Special attention must be paid to the

wiring length and wire gauge.

2.7.1 Connection diagram (when using with the FR-A700 series)

Connection method differs by the inverter series. Perform connection by referring to the Instruction Manual of the inverter.

 Do not connect anything to the inverter power input terminals R/L1, S/L2 and T/L3. Incorrect connection will damage the inverter. Connecting opposite

polarity of terminals P and N will damage the converter and the inverter.

 Use input terminal function selection to assign the terminal used for X10 signal. (Refer to the Instruction Manual of the inverter.)  The power phases of the terminals R4/L14, S4/L24, and T4/L34 and the terminals R/L1, S/L2, and T/L3 must be matched.  Do not insert MCCB between terminals P and N (P and P, N and N).  Always connect the terminal R/L1, S/L2, T/L3 of the converter to the power supply. If the inverter is operated without connecting the terminals to the power

supply, the converter will be damaged.

 Do not insert MCCB or MC between (1) (terminal R/L1, S/L2, and T/L3 input of the Reactor 1) and (4) (terminal R4/L14, S4/L24, and T4/L34 input of the

converter) of the above diagram. It will not operate properly.

 Securely perform grounding (earthing) by using the grounding (earthing) terminal.  Installation of a fuse is recommended. (Refer to page 11)  The MC power supply stepdown transformer is only equipped in the 400V class models.

2.9 Wiring of main circuit (FR-HC2-H400K, H560K)

 Perform wiring securely to conform with the harmonic suppression guideline of the former Ministry of International

Trade and Industry (currently the Japanese Ministry of Economy, Trade and Industry). Incorrect wiring causes the converter to display an alarm or causes an fault or damage.

 Refer to the Instruction Manual of each inverter for the wiring of the inverter. Special attention must be paid to the

wiring length and wire gauge.

2.9.1 Connection diagram (when using with the FR-A700 series)

Connection method differs by the inverter series. Perform connection by referring to the Instruction Manual of the inverter.

 Do not connect anything to the inverter power input terminals R/L1, S/L2, and T/L3. Incorrect connection will damage the inverter. Connecting opposite

polarity of terminals P and N will damage the converter and the inverter.

 Use input terminal function selection to assign the terminal used for X10 signal. (Refer to the Instruction Manual of the inverter.)  The power phases of the terminals R4/L14, S4/L24, and T4/L34 and the terminals R/L1, S/L2, and T/L3 must be matched.  Do not insert MCCB between terminals P/+ and N/- (P and P, N and N).  Always connect the terminal R, S, and T of the converter to the power supply. If the inverter is operated without connecting the terminals to the power supply,

the converter will be damaged.

 Do not insert MCCB or MC between (1) (terminal R/L1, S/L2, T/L3 input of the converter) and (3) (terminal R4/L14, S4/L24, T4/L34 input of the converter) of

the above diagram. It will not operate properly (except for the inrush current limit MC).

 Securely perform grounding (earthing) by using the grounding (earthing) terminal.  Installation of a fuse is recommended. (Refer to page 11)  Connect three sets consisting of one filter capacitor and one filter capacitor alarm detector for 560K.  For 560K, install a set of three MCs to each phase.

NOTE

• When connecting the converter to the inverter, match the control logic (sink logic (initial setting)/source logic). The

converter does not operate properly if the control logic is different.

(Refer to page 60 for the switching of the control logic. Refer to the Instruction Manual of the inverter for the switching

of the control logic of the inverter.)

• Keep the wiring length between terminals as short as possible.

• When sudden large distortion or depression of power supply occurs, reactor may generate abnormal acoustic noise.

This acoustic noise is caused by the power supply fault and not by the damage of the converter.

• Do not connect the DC reactor to the inverter when using a high power factor converter.

• When using a sine wave filter with FR-HC2 (75K or higher), select MT-BSL-HC as a reactor for the sine wave filter.

CAUTION

Check the connection order of the reactor 1 and the reactor 2. Incorrect connection may damage the

converter and reactors.

Always connect the terminal RDY of the converter to the terminal MRS or the inverter terminal of which X10

signal is assigned to. Also, always connect the terminal SE of the converter to the terminal SD of the inverter.

If these are not connected, the converter may be damaged.

2.10 Notes on earthing (grounding)

 Always earth (ground) the converter with its accessories (reactor 1, reactor 2, outside box, filter capacitor).

(1) Purpose of earthing (grounding)

Generally, an electrical apparatus has an earth (ground) terminal, which must be connected to the ground before use. An electrical circuit is usually insulated by an insulating material and encased. However, it is impossible to manufacture an insulating material that can shut off a leakage current completely, and actually, a slight current flow into the case. The purpose of earthing (grounding) the case of an electrical apparatus is to prevent operator from getting an electric shock from this leakage current when touching it. To avoid the influence of external noises, this earthing (grounding) is important to audio equipment, sensors, computers and other apparatuses that handle low-level signals or operate very fast.

(2) Earthing (grounding) methods and earthing (grounding) work

As described previously, earthing (grounding) is roughly classified into an electrical shock prevention type and a noiseinfluenced malfunction prevention type. Therefore, these two types should be clearly distinguished, and the following work must be done to prevent the leakage current having the converter's high frequency components from entering the malfunction prevention type earthing (grounding): (a) Independently earth (ground) the converter with its accessories whenever possible. If independent earthing

(grounding) (l) is not available, use (ll) common earthing (grounding) in the figure below where the converter is connected with the other equipment at an earthing (grounding) point. Do not use the other equipment's earthing (grounding) cable to earth (ground) the converter as shown in (III). A leakage current containing many high frequency components flows into the earthing (grounding) cables of the converter with its accessories. Because of this, the converter must be earthed (grounded) separately from EMIsensitive devices. In a high building, it may be effective to use the EMI prevention type earthing (grounding) connecting to an iron structure frame, and electric shock prevention type earthing (grounding) with the independent earthing (grounding) together.

(b) This converter must be earthed (grounded). Earthing (Grounding) must conform to the requirements of national and

local safety regulations and electrical codes. (NEC section 250, IEC 536 class 1 and other applicable standards).

indicated in the table on page 31.

(d) The converter with its accessories should have their earthing (grounding) points as close as possible to them, and

their earthing (grounding) cables should be as short as possible.

(e) Run the earth (ground) cable as far away as possible from the I/O wiring of equipment sensitive to noises and run

them in parallel in the minimum distance.

(ground) cable size should be no less than the size

(accessories)

(I) Independent earthing (grounding).......Good

(3) Earthing (grounding) of the reactor

(a) The reactor 1 and reactor 2 are usually earthed (grounded) by being mounted securely to the enclosure. If it cannot

be earthed (grounded) securely enough to the enclosure, remove varnish from a mounting hole and use that hole and a cable to earth (ground). (For the position of the varnish-removed mounting hole, refer to the outline dimensions. (Refer to page 157 and 165.))

(b) If the model is equipped with an earth (ground) terminal, wire the cable to that earth (ground) terminal. (Refer to the

outline dimensions for presence/absence of the earth (ground) terminal. (Refer to page 157 and 165.))

(Refer to page 31)

(4) Earthing (grounding) example

(a) Independently earth (ground) the converter with its accessories whenever possible. (b) Wire the earthing (grounding) cable as close as possible to the input cable in parallel. (c) Earth (ground) the high power factor converter with its accessory at one point. (Excluding when the reactors 1 and 2

are mounted on the enclosure surface.)

Compatible inverter for the high power factor converter

(d) When the wiring length between the inverter and high power factor converter (between P and N) is long and they

cannot be set in the same enclosure together, wire the earthing (grounding) cable between the inverter and the high power factor converter as close as possible to the wire between P and N in parallel. When the wiring length is short and the inverter and the high power factor converter can be set in the same enclosure, earth (ground) them at one point as well as (c).

(e) For the earthing (grounding) of the motor, wire the earthing (grounding) cable through the inverter’s earthing

(grounding) terminal.

2.12 Wiring of several inverters to one converter

Up to ten inverters can be connected to one converter. Be sure to use a converter with the capacity higher than the total

capacities of inverters. Additionally, the total capacity of the inverters needs to be higher than half the converter capacity.

If the total inverter capacity is less than half the converter capacity, the converter can be used as a common converter or a

regenerative converter. However, it's harmonic suppression effect reduces.

(1) Junction terminals or cross wiring are used to connect several inverters, so carefully select the wire gauge. Start adding

the inverter capacities from the furthest inverter.

(2) When connecting several inverters, connect starting with the inverter with the highest capacity.

(3) Installation of a fuse, which corresponds with each motor capacity, is recommended for each inverter when connecting

several inverters to one converter. Select a fuse according to the motor capacity.

When using a motor, of which capacity is smaller than the inverter capacity by two ranks or more, select the converter

capacity according to the inverter capacity. (Refer to page 11 and 13.)

(4) Keep the total wiring length within 50m.

Main circuit wiring example

The following diagram shows a connection example when connecting six inverters in total (FR-A720-30K, 15K, 5.5K, 2.2K,

1.5K, and 0.75K) to FR-HC2-55K.

2.13.4 Wiring instructions

 It is recommended to use the cables of 0.75mm2 gauge for connection to the control circuit terminals.

If the cable gauge used is 1.25mm cables are run improperly, resulting in an operation panel contact fault.

 The wiring length should be 30m (200m for the terminal FM) at the maximum.  To minimize EMI, use shielded or twisted cables for connection to the control circuit terminals and place them away

from the main and power circuits (including the 200V relay sequence circuit). For the cables connected to the control circuit terminals, connect their shields to the common terminal of the connected control circuit terminal. When connecting external power supply to the terminal PC, however, connect the shield of the power supply cable to the negative side of the external power supply. Do not directly earth (ground) the shield to the enclosure, etc.

 Use two or more parallel micro-signal contacts or twin contacts to prevent

a contact faults when using contact inputs since the control circuit input signals are micro-currents.

or more, the front cover may be lifted when there are many cables running or the

Micro signal contacts Twin contacts

 Do not apply a voltage to the contact input terminals (e.g. RES) of the control circuit.  Always use relay coil, lamp, etc. for fault output terminals (A, B, C).

 Wiring of the control circuit of the FR-HC2-75K, FR-HC2-H110K or higher

Separate the wiring of the control circuit away from the wiring of the main circuit. Make cuts in rubber bush of the converter side and lead wires.

CAUTION

Do not connect anything to the free terminal (NC) of the control circuit. Using the terminal may cause a damage to the converter and the inverter.

Always connect the terminal RDY of the converter to the terminal MRS or the inverter terminal of which X10 signal is assigned to. Also, always connect the terminal SE of the converter to the terminal SD of the inverter. If these are not connected, the converter may be damaged.

 When Pr. 27 = "9999", the ON state is held until the next start.  When Pr. 28 = "1", turning Y12 signal ON stops the output of the

converter and displays the input current detection alarm (E.CDO). When the trip occurs, Y12 signal stays ON for the time set in Pr. 27 with Pr. 27  9999 setting, and Y12 signal stays ON until a reset with Pr. 27 = 9999 setting. E.CDO does not occur by setting Pr. 28 = "1" while Y12 is ON. Pr. 28 setting becomes valid after Y12 signal turns OFF.

 Set "12 (positive logic)" or "112 (negative logic)" to any of Pr. 11 to Pr.

Set the period from when the input current drops below the Pr. 29 value until the zero current detection signal (Y13) is output.

(2) Zero current detection

(Y13 signal, Pr. 29, Pr. 30 )

 If the input current remains lower than the Pr. 29 setting during the

converter operation for longer than the time set in Pr. 30, the zero current detection signal (Y13) is output from the converter's open collector or relay output terminal.

 Set "13 (positive logic)" or "113 (negative logic)" to any of Pr. 11 to Pr.

16 (output terminal function selection) to assign the function of Y13

signal to the output terminal.

NOTE

 The response time of Y12 and Y13 signals is approximately 0.1s. Note that the response time varies with the load.  Changing the terminal assignment using Pr. 11 to Pr. 16 (output terminal function selection) may affect other functions. Set

instantaneous power failure

 If restart after instantaneous power failure is activated at the inverter side, set Pr. 57 Restart selection = "0" at the converter

side. When Pr. 57="9999," the inverter output is stopped by the fault signal "E.IPF" from the converter even though the automatic restart after instantaneous power failure is activated in the inverter.

CAUTION

The motor and machine will start suddenly after occurrence of an instantaneous power failure (after the reset

time has elapsed). Stay away from the motor and machine when automatic restart after instantaneous power

failure has been selected.

If the automatic restart after instantaneous power failure function has been selected, apply the CAUTION

stickers, which are supplied with the Instruction Manual of the inverter, to easily visible places.

the number of retries.)

A fault output is provided during the retry

operation.

Set the waiting time from when a converter

fault occurs until a retry is made.

Clear the number of restarts succeeded by

retries.

 Retry operation automatically resets a fault and restarts

the converter when the time set in Pr. 68 elapses after the converter trip.

 Retry operation is performed when Pr. 67  "0". Set the

number of retries at a fault occurrence to Pr. 67.

 When retries fail consecutively more than the number of

times set in Pr. 67, a retry count excess fault (E.RET) occurs, resulting in a converter trip. (Refer to the Retry failure example.)

 Use Pr. 68 to set the waiting time from when the converter

trips until a retry is made in the range of 0 to 360s. (When the setting value is "0s", the actual time is 0.1s.)

 Reading the Pr. 69 value provides the cumulative number

of successful restart times made by retries. The cumulative count in Pr. 69 increases by 1 when a retry is successful. Retry is regarded as successful when normal operation continues without a fault for the Pr. 68 setting multiplied by four or longer (6s at the shortest). (When retry is successful, cumulative number of retry failure is cleared. )

 Writing "0" in Pr. 69 clears the cumulative count.

During a retry, RTY signal is ON. For RTY signal, assign the function by setting "11 (positive logic)" or "111(negative logic)" in any of Pr. 11 to Pr. 16 (output terminal function selection).

NOTE

Changing the terminal assignment using Pr. 11 to

Pr. 16 (output terminal function selection) may affect

other functions. Set parameters after confirming

the function of each terminal.

Description of parameters

 Using Pr. 65, you can select the fault that will cause a retry. No retry will be made for the fault not indicated. (Refer to page

NOTE

 The data stored as the error reset for retry is only that of the fault which occurred the first time.

 When an converter fault is reset by the retry function at the retry time, the accumulated data of the electronic thermal

relay function, etc. are not cleared. (Different from the power-ON reset.)

CAUTION

Stay away from the motor and machine when the converter trips while the retry function is selected. Motor and

machine will start suddenly (after the reset time has elapsed) after a converter trip.

If the retry function has been selected, apply the CAUTION stickers, which are supplied with the Instruction

Manual of the inverter, to easily visible places.

(1) Reset selection

 You can select the enable condition of reset function (RES signal, reset command through communication) input.

 When Pr. 75 is set to any of "1, 3, 15, 17", a reset can be input only when the converter is tripped.

NOTE

 Inputting the reset signal (RES) during operation also resets the inverter. The motor coasts since the inverter being

reset shuts off the output. Also, the cumulative value of the electronic thermal relay is cleared.

 The reset key of the parameters is only valid when the converter is tripped, independently of the Pr. 75 setting.

(2) Disconnected PU detection

 This function detects that the PU (FR-DU07-CNV/FR-PU07) has been disconnected from the converter for 1s or longer

and causes the converter to provide a fault output (E.PUE) and to trip.

 When Pr. 75 is set to any of "0, 1, 14, 15", operation continues if the PU is disconnected.

NOTE

 When the PU has been disconnected since before power-ON, it is not judged as a fault.

 To make a restart, confirm that the PU is connected and then reset the converter.

 When RS-485 communication operation is performed through the PU connector, the reset selection/PU stop selection

function is valid but the disconnected PU detection function is invalid.

(3) PU stop selection

 When Pr. 75 is set to any of "14 to 17", input from the PU stops the converter.

 When the converter is stopped by the PU stop function, " " is displayed. A fault output is not provided.

(4) How to restart the motor stopped by input from the PU (PU stop (PS) reset method)

3)Turn SOF signal OFF and restart the converter

operation.

(b) Parameter unit (FR-PU07)

1)Turn SOF signal ON and stop the converter operation.

2)Press
