- Always ground the ground terminal to prevent disasters such as fire and electric shock and to minimize noise.

® Use a reliable crimp terminal for connection between a terminal and wire. ¯ After terminating the connection (wiring), check the following items:

a. Whether the connection is correct b. Whether all necessary connections have been made c. Whether there is a short-circuit or ground fault between terminals and wires

° Connection modification after power-on

The smoothing capacitor in the direct current part of the main circuit cannot be discharged quickly after the power is turned off. Use a multimeter to check that the voltage of the direct current (DC) is reduced to the safety range (25V dc or less) after the charge lamp goes off to avoid danger. Check that the voltage is zero before short-circuiting a circuit because the residual voltage (electric charge) may cause sparks.

1. Always connect the ground wire,

WARNING

otherwise electric shock and fire could occur.

2. Ensure that a licensed specialist performs the wiring work.

3. Check before starting the wiring that the power is off,

otherwise electric shock could occur.

U, V, W Drive output Connects 3-phase motor. P1, P(+) For connection of DC

P(+), N(-) For DC intermediate circuit Connected to DC link circuit terminal

G For drive grounding Ground terminal for drive chassis (case).

(1) Main power supply input terminal

1 Connect the main power supply input terminals to the

power supply via a molded case circuit breaker for circuit protection or earth leakage circuit breaker. An earthleakage circuit breaker which can also detect DC current is recommended. Phase -sequence matching is unnecessary.

2 It is recommended that a magnetic co ntactor is connected

to prevent any failure or accident from becoming serious by disconnecting the drive from the power supply when the drive protective function operates.

3 Do not turn on or off the main power supply to start or stop

the drive; instead, use the control circuit terminal FWD/REV or the RUN/STOP key on the keypad panel. If it is unavoidable to turn the main power supply on or off to start or stop the drive, it must not exceed once per hour.

(2) Drive output terminal [U, V, W]

1 Connect these terminals to the 3-phase motor with the correct phase -sequence. If a motor rota-

tion direction does not correspond to the correct rotation direction, exchange any two of the U, V, and W phases.

2 Do not connect a phase -advance capacitor or surge absorber to the drive output. 3 A very long wiring length between the drive and the motor causes a high frequency current to

flow due to floating capacity between cables, making the drive trip, increasing the leakage current and deteriorating the accuracy in the current display. To prevent such trouble, the wi r-

ing length to the motor should not exceed 165 feet (50 m). When the drive is operated in the low noise mode (carrier frequency: 8 to 15 kHz) and the wi ring length is long, add an optional output circuit filter.

Use this terminal to connect a input power-factor co rrecting DC reactor (optional). Remove the jumper co nnected in the factory before connecting the DC reactor (see Figure 2-3-2). Use diagonal cutting pliers to cut the surface cover barriers from P1, P(+) terminals before connection. If no DC reactor is used, do not remove the jumper.

(4) Drive grounding terminal[ G]

Always ground the drive grounding terminal [ G] for safety and noise reduction. Grounding of the metal frames of electric equipment has to be done in accordance with the national and local safety specifications in force.

1 Connect a thick and short wire to the grounding terminal

of the drive for connection with a ground electrode prepared exclusively for the drive sy stem.

FWD terminal is short-circuit to CM terminal in the factory. Pressing the RUN key on the keypad panel can start forward operation. If function F02 is 0, short-circuit FWD and CM and press the RUN key for forward operation, or short-circuit REV and CM for reverse operation. If function F02 is 1, then short-circuit FWD and CM for forward operation, or REV and CM for reverse operation. Regardless of whether function F02 is set to 0 or 1, short-circuiting both FWD – CM and REV – CM brings the drive to a deceleration-stop. Refer to F02 “Operation method” for details.

(3) Analog input terminal (13, 12, 11, C1)

Use these terminals to connect external input analog voltage and analog current and frequency setting device (POT). For connecting a contact to this circuit, use a twin contact for fine current si gnal. Do not use a contact for terminal 11.

WARNING

1. The STOP key is valid only when the function has been set. Prepare another switch for emergency stop. When the data of F02 is selecte “2” or “4”, the operation cannot be stopped using the STOP key on the keypad panel,

otherwise accidents could occur.

*Note the following when wiring:

(1) Surge absorber connection

When the exciting coil of the magnetic contactor or relay in the control circuit or drive peripheral circuit is opened or closed, a surge voltage (noise) is generated with a sudden current change. Due to this surge voltage, the drive control circuit or peripheral equipment may malfunction. If so, directly connect a surge absorber to both ends of the coil. (See Figure 2-3-4).)

(2) Co ntrol circuit wiring

1 Wires connected to control circuit terminals must be AWG

20 (0.5mm2) shielded wire or twisted vinyl wire. Remove the sheath as shown in Figure 2-3-5 and then connect it.

2 Keep the wiring of the main circuit, external relay se-

quence circuit and control circuit as far away from each other as possible. If they must be adjace nt, cross them at right angles.

3 Use a twisted-pair shielded wire for long wiring

distances.

(3) Shielding sheath connection

Connect one end of the shielding sheath of a shielded or twisted-pair shielded wire to the ground terminal as shown in Figure 2-3-6. Do not connect the other end.

2-4-1 Harmonic component

A harmonic component which may influence the phase -advance capacitor and generator is included in the drive input current. If necessary , connect a power-factor correcting DC reactor (DCR) (option) for the drive.

2-4-2 Noise

When noise generated from the drive may affect peripheral equipment, and noise generated from peripheral equipment may malfunction the drive, the following basic countermeasures should be taken.

1. When noise affects other devices via power and ground wires

· Separate the ground of the drive and that of the affected device.

· Connect a noise filter to the drive power wire.

· Use an isolation transformer to separate the power supply of the drive and that of the affected device.

2) When another device is affected by induction or radiation

· Separate the main circuit wiring of the drive from the control wiring and wiring of the affected device.

· Encase the drive main circuit wiring in a metal tube and ground the metal tube near the drive.

· Encase the drive in a metal rack and ground the rack.

· Connect a noise filter to the drive power wire.

3) When noise generated from peripheral equipment affects the drive

· Use twisted or twisted-pair shielded wires for the drive control wiring. Ground the shields.

· Connect a surge absorber in parallel to the coil of the magnetic contactor and solenoid .

· If the power supply includes much distortion of the waveform or surge, connect an impedance matching AC reactor for coordination of power supply.

2-4-3 Leakage current

Leakage current flows through the drive I-O wiring and motor stray capacitance when the drive transistor is turned on and off. Table 2-3-3 lists the countermeasures for the problems caused by the leakage current.

Table 2-3-3 Countermeasures for leakage current

1 Trip of earth leakage circuit breaker

on main power supply side

2 Trip of external thermal O/L relay

Problem Countermeasures

Set the carrier frequency lower. Shorten the wiring between the drive and motor. Increase the ELCB/RCD sensitivity current. Replace the ELCB/RCD with an ELCB/RCD that is designed for high frequencies. Set the carrier frequency lower. Increase the thermal O/L relay set value. Use the drive electronic thermal O/L relay.

3 Operation

!

3-1 Inspection and Preparation before Operatio n

Check the following before operation: (1) Check whether the connection is correct,

For 3-phase 230V series, check whether the power supply is connected correctly to the L1/R, L2/S and L3/T terminals. For single-phase 230V series, check whether the power supply is connected correctly to the L1/L and L2/N terminals. Also check whether the drive grounding terminal

is securely connected.

G (2) Check for short-circuits and ground faults between terminals and between live parts. (3) Check for loose terminals, connectors, and screws. (4) Check whether the motor is separated from mechanical equipment. (5) Set switches to OFF before turning on the power so that the drive will not start or operate abnor-

mally at power-on.

(6) Check the following after power-on:

a) Check for alarms displayed on the keypad panel.

1. Always install the surface cover before turning on the power.

WARNING

Do not remove the surface cover during conduction,

2. otherwise electric shock could occur.

3. Do not operate a switch with wet hands,

otherwise electric shock could occur.

3-3 Trial Run

The motor rotates when a frequency value and running command are input from the keypad panel or external signal terminal. Refer to Table 3-3-1. Use a low frequency (about 5Hz) for trial runs A frequency can be set using the built-in frequency setting POT (VR) , and forward/stop can be performed using the keypad panel with the functions set in the factory.

Table 3-3-1 Running command

Operation method Frequency setting Running command Operation by using keypad panel

Operation by using external signal terminal

(When built-in POT (VR) is used) The frequency increases when the variable resistor is turned clockwise and reduces when it is turned counterclockwise. The motor accelerates when the variable resistor is turned clockwise during operation and decelerates when it is turned counterclockwise.

(When the UP/DOWN key is used) Frequency increases when the UP key is pressed.

It reduces when the DOWN key is pressed.

Operation starts when the RUN key is pressed.

The motor decelerates and stops when the STOP key is pressed.

Operation starts when FWD (REV) terminal is connected.

The motor decelerates and stops when the FWD (REV) terminal is disconnected. * Operation is not stopped although the STOP key is pressed. (When the data of F02 is set to “2” or “4”)

Check the following items: a) Rotation direction b) Whether rotation is smooth (whether there is a motor buzzing noise or abnormal vibration) c) Whether acceleration and deceleration are smooth d) Whether the drive cooling fan is rotating (1.5kW or more) If no abnormality is detected, check the item again by increasi ng the frequency. Even if the output from the drive is stopped, you will be get an electric shock when you touch the main circuit terminals such as drive output terminals U, V and W if the voltage is supplied to the main power supply input terminal. The smoothing capacitor in the drive has been charged when the power is turned off and it is not discharged immediately. Before touching the electric circuit, wait until at least five minutes have elapsed after power-off and the charge lump is off, indicating the voltage is already low. After checking normality in the above trial run, start operation.

Contents of operation

If the drive output current momentarily exceeds the ove rcurrent detection level because of an overcurrent in the motor or the short-circuit in the output circuit, the output is shut down, an alarm is issued, and the drive is tripped.

If the DC voltage of the main circuit exceeds the overvoltage dete ction level because of an increase in the regenerating current from the motor, etc., output is shut down, an alarm is issued, and the drive is tripped. However, prote ction against inadvertent overvoltage loading (e.g., highvoltage line) might not be provided.

Undervoltage LU If the DC voltage of the main circuit falls below the undervoltage detection level

because of a lowered power supply, output is shut down to protect the drive. If the restart function after momentary power failure is not activated, an alarm is issued and the drive is tripped. If the restart function is activated, the drive restarts automatically with no alarm. For further details of the protective function, refer to the descriptions of Function

6-2 Alarm Reset

To release the trip status, enter the reset command by pressing the reset key or from terminal (RST) after removing the cause of the trip. Since the reset command is an edge operation, be sure to input a command string

such as OFF ON OFF as shown in Figure 6-2-1. When releasing the trip status, set the operation command to OFF. When the operation command is set to ON, check that operation starts after resetting. If the cause of tripping is Er1, reset the error and initialize data. If the drive is not reset, contact GE Fuji.

Inspections are usually done to check the following:

1) The expected performance (satisfying the standard specification) is obtained.

2) The environment satisfies the standard specification.

3) The keypad panel display is normal.

4) There are no abnormal sound, vibrations or unpleasant odors.

5) There are no overheating marks or discoloration.

8-2 Periodic Inspection

The periodic inspection must be executed after stopping the operation and cutting off the power source and removing the surface cover. After power-off, time is needed for the smoothing capacitors in the DC section in the main circuit to discharge. To prevent electric shock, make sure that the voltage falls down to the safety value (25Vdc and below) using a multimeter after the charge lamp (CRG) goes off.

WARNING

1. Start inspection five minutes or more after turning off the power supply. (Check that the charge lamp (CRG) goes off, and check the voltage is 25V dc or below between terminals P(+) and N(-) There is danger of electric shock.

2. Only the designated person can perform the maintenance and replace components (Take off any metal objects such as a watch or ring.) (Use insulated tools.)

3. Never modify the drive. There is danger of electric shock or injury.

8-3 Electrical measurements in the Main Circuit

The indicated values depend on the meter types because of harmonic components included in the voltage and current of the main power supply (input) and the output (motor) side of the drive. Therefore, when measuring

with a meter for the commercial power frequency, use the meters shown in Table 8-3-1. The power-factor cannot be measured using the power-factor meter available on the market which measures the phase difference between voltage and current. When the power-factor must be measured, measure the power, voltage, and current on the input side and output side. Then, calculate the power-factor using the following formulas: Three-phase

Power factor =

3 x Voltage [V] x Current [A]

Electric power [W]

x 100 [%]

Single-phase

Power factor =

Voltage [V] x Current [A]

Electric power [W]

x 100 [%]

8-4 Insulation Test

As much as possible, do not test the drive with a megger because an insulation test was done at shipping from the factory. If a megger test must be done, test as described below. If the test method is incorrect, there is a possibility of damaging the product. Incorrect use of test specifications for the dielectric strength test may damage products like megger test. If the dielectric strength test must be conducted, contact your local distributor or nearest GE Fuji’s sales office.

(1) Megger test for the main circuit

1) Test with a 500V dc megger.

2) If the test voltage is connected to the control circuit, remove all connection wires to the control circuit.

3) Connect the main circuit terminals using common wires as shown in Figure 8-4-1

4) Execute a megger test only between the common wire connected to the main circuit and the ground (terminal G).

5) If the megger indicates 5MΩ or more, it is normal. (This is the value measured with a drive only.)

(2) Insulation test in the control circuit

The megger test and the dielectric strength test must not be executed in the control circuit because those parts will be damaged and cannot be repaired. Use a high-resistance multimeter for the control circuit.

1 Remove all external wiring from the control circuit terminals. 2 Execute a continuity test between grounds. If the result is 1MΩ or more, it is normal.

(3)External main circuit and sequence control circuit

Remove wiring from all the terminals of the drive in order not to apply the test voltage to the drive.

Molded case circuit breaker

For input power-factor correcting

AC reactor (ACR) DC reactor (DCR)

The molded case circuit breaker (MCCB) is connected for protecting the main circuit wiring to the drive and for turning power on and off. The rated current or the rated interrupting capacity varies according to the power supply specifications. This is connected in the following cases. When the power transformer capacity is more than 500 kVA. When the imbalance ratio between phases of source voltage exceeds 2% (The value is equivalent to our conventional allowable value.)

Imbalance ratio between phases = ——————————————————— x 67 [%]

Maximum voltage [V] - Minimum voltage [V]

Average voltage among three phases [V]

To reduce input harmonic current The input power factor is improved to 0.75 to 0.85 (ACR). The input power factor is improved to 0.9 to 0.95 (DCR). If there is a thyristor load in the same power supply, if the capacitor for powerfactor correcting is turned on or off, or if the surge voltage in the power supply is large (ACR only)

* The AC reactor is unnecessary when the DC reactor is used. Magnetic contactor (MC)

The drive can be operated without connecting the magnetic contactor. When the

drive protective function is activated, this should be connected to turn off the

power for safety. Surge absorber This is connected to suppress the surge generated by the exciting coil when

switching on or off the magnetic contactor and the control relay.

Reactor for radio noise suppression Frequency setting POT (VR)

This is used for noise suppression when the drive causes excessive noise in a ra-

dio or electronic equipment around the drive.

This is connected when the frequency is set from the control circuit termi nal us-

ing drive power.

12-2 Compliance with EMC directive in EU [Applicable to products with CE mark]

12-2-1 General

The CE mark indicated on the AF-300C11series concerns with European minister directorate di rective 89/336/EEC concerning the environmental electromagnetic compatibility EMC, and other directives are not included. The CE mark does not prove that the entire machine or system housing our product complies with the EMC directive. Therefore indicatio n of the CE mark to the entire machine or system will be done at the responsibility of the manufacturer or the machine. This is because:

1) The CE mark attached on our product supposes operation of the product under certain conditions. Satisfaction of the conditions is up to the manufacturer of the machine.

2) Generally speaking, various devices are used in a machine or system as well as our product. Therefore

consideration for the entire machine or system must be paid by the manufacturer of the machine. The EMC directive includes immunity to the incoming noise and emission of outgoing noise. The general purpose drive houses an internal element switching at a high speed which generates electric noise. Applicable standards Immunity: EN 61800-3/1996 Emission: EN 61800-3/1996 Above-mentioned "certain conditions" include installation of a dedicated RFI filter in a metallic control panel. Refer to in exclusive Instruction Manual for RFI Filter for details.

12-3 Compliance with low voltage directive in EU [Applicable to products with TÜV or CE mark]

12-3-1 General

The general purpose drive is applicable for the low voltage directive in EU. Compliance of the AF300C11series with EN 50178/1997 has been obtained from a testing organization in EU and compli ance with the low voltage directive is asserted.

12-3-2 Precautions

Refer to "Compliance with low voltage directive in EU" on pages 2 and 3 when using our product as one complying with the low voltage directive in EU.

13 Electromagnetic Compatibility (EMC)

13-1 General

In accordance with the provisions described in the European Commission Guidelines Document on Council Directive 89/336/EEC,GE Fuji has chosen to classify the AF-300C11 range of Drives as "Complex Components". Classification as a "Complex Components" allow s a product to be treated as an "apparatus", and thus permits compliance with the essential requirements of the EMC Directive to be demonstrated to both an integrator of AF-300C11 Drives and to his customer or the installer and the user. AF-300C11 Drives are supplied `CE-marked', signifying compliance with EC Directive 89/336/EEC when fitted with specified filter units installed and grounded in accordance with this sheet. This Specification requires the following performance criteria to be met.

EMC product standard EN61800-3/1996

Immunity : Second environment ( Industrial environment ) Emission : First environment ( Domestic environment )

Finally, it is customer’s responsibility to check whether the equipment conforms to EMC directive.

13-2 RFI Filters

It is strongly recommended that the appropriate AF -300C11 input filter is used, as shown in the followings, to limit RF current flowing into the main supply circuit. Without an input filter a AF -300C11 installation may not meet statutory requirement. AF -300 Drives contain high-power semi-conductor devices which are switched at high speeds to synthesize a near-sinusoidal current wave form across the frequency range of output. Rapidly-changing voltages and currents will generate some degree of electromagnetic emission. Emissions will be predominantly conducted through the motor and the mains supply cables, although some radiated emissions will be detected in close proximity to the drive system. It is essential that precautions are taken both at the design stage and at the time of installation to prevent radio frequency interference (RFI) from the drive system affecting sensitive equipment in close proximity. The RFI filters range are designed especially for the AF -300C11 Drive and help to ensure EMC compliance of machinery an installations using the Drives. The Drives single phase series may be mounted on top of the filter using the integral fixing positions, the intention being that valuable space inside wiring cabinets may be saved. (Refer to Table 13-2-2)

In case of single phase power supply

13-3 Electromagnetic Compatibility (EMC) Recommended Installation Instructions

It is necessary that these instructions must be followed to conformed to EMC Directive. Follow the usual safety procedures when working with electrical equipment. All electrical connections to the filter, Drive and motor must be made by a qualified electrical technician.(Refer to Fig. 13-3-1 and Fig. 13-3-2)

Use the correct filter according to Table 13-2-1. Install the Drive and filter in a electrically shielded metal cabinet. The back panel of the wiring cabinet of board should be prepared for the mounting dimensions of the filter. Care should be taken to remove any paint etc. from the mounting holes and face

area of the panel. This will ensure the best possible grounding of the filter. Use a screened cable for the control , motor and other main wiring which are connected to the Drive. The screens should be securely grounded. It is important that all wire lengths are kept as short as possible and that incoming mains and outgoing motor cables are kept well separated.

Power Supply

In case of a ferrite ring is provided with the filter, fit a ferrite ring to the motor cable with the 3

phase conductors only passing twice through the center of the ferrite.
