Notes for the Use of Inverter

Special Precautions

 Use the inverter only within the allow able ambient temperature range (-10～

50 ).

Since the service life of the inverter is greatly affected by the ambient temperature, use it within the allowable temperature range. Also, observe the installation directions and conditions. (Refer to P.17)

 The inverter will be damaged if the power voltage is applied to its output side.

Applying power voltage to the output terminal U, V or W will damage the inverter.

Check carefully for faulty wiring and operation sequence (commercial switching circuit, etc.). Never apply a voltage exceeding the allowable range.

 Never touch the inside of the inverter during operation.

It could be extremely dangerous since the inverter contains high-voltage circuit. Be sure to turn OFF the power of the inverter and wait at least 5 minutes before making an internal check. Do not touch the heat sink or the braking resistor during operation as these parts are at high temperature.

 Radio interference

The main circuit of the inverter contains a high-frequency harmonic component and may interfere with communicating equipment s (such as AM radio) near by. The severity of inte rference depends on the radio fi eld strength a nd is hard to be eliminated completely. While it ma y be reduced by relocating radio antenna, using noise filter, housing the inverter in a metal box, or routing cables in conduit. (Please inquire separately.)

 Do not conduct insulation resistance test between wires of the inverter.

To measure insulation resist ance between power cord and motor wires, please remove the cables connected to the invert er and conduct test w ith them. Do not conduct insulation test on the control circ uits. However, insulation test can b e performed between charging unit and the ground.

 Do not use a ma gnetic contactor which is connected to the po wer side or load side of the inverter to start or stop the motor (inverter).

Frequent ON/OFF switching on the power supply side can cause inverter malfunction. Also, do not conduct ON/OFF switching on the load side during inverter operation, or it can cause fault trip of the inverter. Start or stop the motor by operating signals of the inverter only.

 Do not connect a power capacitor or a surge absorber to the output side of the inverter.

Such device can damage the inverter, resulting in breakage of capacitors and other parts. Remove it if connected.

 Do not use the inverter for load other than a motor or for a 1-phase motor.

8

Notes for the U se of Inverter

 Precautions for inverter’s protection function

The inverter integrates various protection functions such as stall prevention, current limiting and over-current shut-off. These protection functions are designed to protect the inverter against the sudden abnormal conditions, instead of general control functions.

Therefore, avoid using them in applications where they will be activated under normal conditions.

Failure to do so may shorten the inverter's service life or damage the inverter.

Always measure the output current, etc. with a meter, check the details of the fault trip memory, and confirm that operation conditions conform to the precautions and specifications are correct.

In case the protection function is enabled, reset and restart the inverter only after all faults had been removed.

Besides, if the breaker on the input side of the inverter trips, it may be due to the wiring errors or the damaged parts in the inverter.

Find out the breaker tripping causes, and reconnect the breaker after all faults had been removed.

 Take the measure of suppressing higher order harmonics.

The higher order harmonics generated by the inverter may result in over-heating or damage of the intake phase capacitor or the electric generator.

 Precautions for motors of 400V series

If the inverter is used to drive the motors of 400V series, in this case, use the motors that had undergone a reinforced insulation treatment or adopt a method of suppressing the surge voltage.

The surge voltage on the motor terminal produced due to the wiring parameters may lead to the aging of insulation of the motor for such reason.

 The electronic thermal relay may be unable to provide an overheating protection for motors. It is therefore s uggested to also set an external thermal relay or a PTC thermistor to provide the overheating protection.

3.3.2 Precautions on Wiring Main Circuit

■ Precautions on Wiring

To avoid mistakes in wiring and operation, be sure to observe the following guides. (Failure to do so may damage the unit.)

· Always connect the power source to input terminals (R/L1, S/L2, T/L3), and connect the motor to output terminals (U, V, W). Please connect the output terminals (U, V, W) in the correct sequence. Failure to do so may cause the motor to run in the reverse direction.

· Use round crimp terminals with sleeve for power source and motor connections. Select crimp terminals according to wire sizes and screw sizes.

· After wiring main circuit, confirm the tightening condition of terminals.

· Main circuit must be wired prior to control circuit. Otherwise, re-tightening operation is not possible after control circuit wiring is completed.

· When connecting directly to a transformer of large capacity (500 kVA or more), always install an AC reactor on the input side of the inverter.

Note 1: It is recommended to use teflon insulated wire (600 V, Class 2, allowable operating temperature up to 75 °C) for main circuit wiring.

Note 2: Use wires with larger diameter if the wiring distance is long.

Note 3: If the over-current trip of the circuit breaker is a magnetic type, the device could become overheated due to higher harmonics. Use a load rate of 50% or lower in this case.

Note 4: Use a circuit breaker for the motor.

Note 5: Always connect protective devices against over-current, short-circuit and current leakage on the input side.

■ Precautions on Using Regenerative Brakes

· When using regenerative brakes, set the parameter P026 to "0". Since its factory setting is "1", the brakes will not be activated in that case.

· Specifications for regenerative brakes are shown as follows. Carefully consider the operation conditions before using them. Note that the inverter could be damaged if a brake outside specifications is used.

Notes for Customers when selecting a braking resistor

1) Resistance Value (Ω)

When selecting a resistor by referring to the resistance value as shown in the above table, a larger resistance value can by chosen, however, the braking torque shall be decreased accordingly.

2) Allowable continuous power rating (W)

A larger power rating may be chosen when referring to the value as shown in the above table, yet in this case, it will cause the resistor to produce lots of heat (300℃).

Please cooperate with the resistor manufacturer to take precautions during installation.

3) Allowable braking utilization rate (%)

The larger the continuous power rating of the braking resistor, the higher the utilization rate can be used in the theoretical calculation. Yet in this case, the resistor in the inverter shall be over-heated, therefore, it is suggested to use the utilization rate of 5% as specified.

Common Precautions on Terminals for Control Circuit

■ Precautions on Wiring

· For wiring of terminals of control circuit, strip specified length of insulation coating before connecting.

· Loosen the terminal screws and insert the wires from the bottom of the terminal block, and tighten the screws to specified tightening torque.

· Any loose connection could cause wire to come off and lead to malfunction. Also, over-tightening could cause short-circuit due to the broken screws and unit, thus lead to malfunction

· Use shielded cables for all control signal lines and separate them from power lines or high-voltage circuits (20 cm or more).

· Wiring length of control signal lines should be within 30m.

· Since input signals of control circuit are feeble, use dedicated terminals for feeble signals to avoid poor contact during contact input.

· Connect the core wires at the same time.

· Do not lift the core wire to make a connection through welding. A disconnection is possible in this case due to vibration.

· After wiring, do not apply voltage to the cables.

· In respect of the terminal structure, if the wire is tightened in an anti-clockwise direction, it is an error connection.

Unplug the wire and reconnect it after the correct terminal had been confirmed.

4. Operation Method (Basic & Trial Operations)

4.1 Safety Precautions

Always close the terminal cover before turning ON the inlet power.

Do not open the terminal cover while the power is ON. Failure to do so may result in electric shock or fire.

Do not operate the switches or dials with wet hands. Failure to do so may result in electric shock.

Do not touch the inverter terminals even when the inverter is stopped while the power is ON. Failure to do so may result in electric shock.

The

STOP

button is not designed for emergency stop purposes.

Set a separate button for emergency stop. Failure to do so may result in injury.

The heat sinks and braking resistors are at high temperature, so do not touch them. Doing so may result in burns.

The inverter can be easily switched from low speed to high speed, so confirm carefully the allowable range of the motor and machine before making settings. Failure to do so may result in injury.

Set separate holding brakes if required. Failure to do so may result in injury.

Before turning on the power, check the following points again.

1. Check again whether all wirings are correct.

The reversed wirings between the power supply and the loads in particular could damage the inverter.

2. Check whether the voltage rating of the inverter matches with that of the power supply.

3. Check whether a phase-lead capacitor is connected to the motor.

The connection of a phase-lead capacitor may result in faults to the inverter and capacitor.

4. Confirm the set frequency before starting a trial operation.

4.7.2 Changing Function Parameters During Operation

Changing parameters during operation are likely to cause great changes to the motor and motor load, thus resulting in a sudden stop of them.

(Please take measures to ensure personal safety.) Failure to do so may result in injury.

For the function parameters that can be changed during operation, please refer to items marked with “○” in “Changeable during Operation” of “4.8 List of

Function Parameters”.

Setting Example:

Change the first deceleration time from 5.0s to 10.0s (that is, change the setting value of parameter P002 from “5.0” to “10.0”). Confirm

Use the current data to control the motor

①

Confirm the operation status (operating at

50.0Hz ).

② Press

MODE

button to show “Fr”. MODE

③ Rotate the encoder to “P0--”.

④ Press the encoder to show “P001”.

⑤ Rotate the encoder to “P002”.

⑥ Press the encoder to show “5.0” and it flickers.

⑦ Press the encoder to show “10.0” and it flickers.

Use new data to control the motor

① Press the encoder to set the data. It shows “P002”.

4. Operation Method (Basic & Trial Operations)

• The initial values of such parameters may vary with the different ratings of inverters.

• If you monitor parameters that cannot be set during operation when the operation signal is OFF, the setting values will flicker and then become changeable.

• The changed communication parameters will only be effective after the inverter is rebooted (namely, the power is changed from OFF to ON).

• During operation, it is impossible to change to auto torque boost from manual torque boost and vice versa.

4. Operation Method (Basic & Trial Operations)

4.14 Auto-tuning

When operating in the sensorless vector control mode, or operating the auto torque boost in the V/F control mode, be sure to perform the auto-tuning for all motores before their first operation. Otherwise, they cannot be controlled normally. Measure the motor constants for control use and automatically save them to parameter P208 to P212 (for the 2 nd motor: P216 to P220)

The inverter will automatically drive the motor within the range of uppter/lower frequency limit after the auto-tuning starts.

Do not start an auto-tuning if there is a danger with the motor that is being driven.

Do not approach the unit and the conductive parts during auto-tuning.

Failure to do so may result in injury and accidents.

· Do not connect loads and other objects to the motor shaft during auto-tuning. It is suggested that it should be done in the standalone status.

The auto-tuning cannot be normally performed if loads and objects with greater inertia are connected.

Perform the auto-tuning in a free rotation state without loads as far as possible.

· Start the auto-tuning only after the motor had come to a complete stop.

■ Auto-tuning Procedure:

· Perform it in the following order (1 to 4).

1．Set motor specifications with the parameters P203 to P207 (for the 2 nd motor: P216 to P220).

· Be sure to set them before the start of the auto-tuning.

2．For the 2 nd motor only: switch to the 2 nd Characteristics Selection status.

· Switch the selection status by inputing control signals.

(Refer to parameters P101 to P106.)

3．After setting P202 to “1”, swich to the Operation Status Display mode by pressing the

MODE

button.

· It will enter the measurement ready status after the panel displays “Att1”.

(Reset P202 to “0” to exit the ready status if needed.)

· It takes about 2 minutes for the measurement to end.

· If the measurement needs to be stopped halfway, press

STOP button. The motor constants will not be saved if it is stopped before it displays “End” (“Att1” to

“Att3” flashing) and it will return to the measurement ready status (3.).

(Reset P202 to “0” to exit the ready status if needed.)

· It will display “End” if the measurement ends normally, and the motor constants will be saved.

Press

4. Operation Method (Basic & Trial Operations)

4.15 Vector Control

In sensorless vector control mode, the output current of inverter can be divided into the energizing current and the torpque current in the vector operation and make a compensation for the frequency and voltage to ensure that the current flowing into the motor matches up with the load torque.

This function is effective for the case that the load fluctuates sharply when high start-up torque or sufficient torque at lower speed is required.

In sensorless vector control mode, please use the inverter in the following conditions.

· A squirrel-cage induction motor should be selected.

· Please select the inverter with the capacity equivalent to or 1 level higher than the motor capacity.

· The motor must be a 2-pole, 4-pole or 6-pole one.

· It must operate in standalone mode (i.e. one motor is driven by one inverter).

· The maximum wiring length between the inverter and the motor must not exceed 30m.

· The carrier frequency should be higher than 2.5kHz.

If the above conditions are not satisfied, sound operation performance cannot be achieved.

· Uneven rotations occur more often than in the V/F control mode. It is not applicable to the load whose minor rotation may cause problems at lower speed.

In this case, V/F control should be selected.

· The output frequency ranges from 0.5Hz to 120Hz when the sensorless vector control is selected.

· The “P007: carrier frequency” is only effective in the frequency range of 2.5kHz to15.0kHz when the sensorless vector control is selected.

The setting value of carrier frequency shall be automatically changed to 2.5kHz if the “P007: Vector Control Selection” is set to “1” (sensorless vector control) in the condition that the carrier frequency is set to “0.8kHz to 1.6kHz”.

· In sensorless vector control mode, carrier frequency in area where output frequency is relatively lower may vary accordingly.

76

4. Operation Method (Basic & Trial Operations)

【 Setting Procedure for Sensorless Vector Control】

Make a setting and carry out the trial operation in the following order (1 to 4).

1. Selecting the inverter control mode

· In “P006: Vector Control Selection” mode, you may select the V/F control mode or the sensorless vector control mode.

It had been initially set to V/F control mode, therefore, it is necessary to change it to sensorless vector control mode (P006 = “1”).

2. Setting based on various specifications of the motor

The following setting values shall be taken as the benchmark for the auto-tuning, so be sure to set them before the start of the auto-tuning (parameter P202).

1) Setting of Motor Capacity:

· Set the applied motor capacity to “P203: Motor Capacity”.

The initial value of the “Motor Capacity” had been set equivalent to the

“Inverter Capacity”.

2) Setting of Motor Polarity:

· Set the applied motor polarity to “P204: Motor Pole Number”.

The initial value of the “Motor Polarity” had been set to “4 poles”.

3) Setting of Motor Rated Voltage

· Set the applied motor rated voltage to “P205: Motor Rated Voltage”.

The initial value of the “Motor Rated Voltage” had been set to “380V” (in the

400V mode)”.

4)Setting of Motor Rated Frequency

· Set the applied motor rated frequency to “P206: Motor Rated Frequency”.

The initial value of the “Motor Rated Frequency” had been set to “50Hz”.

5) Setting of Motor Rated Current

· Set the applied motor rated current to “P207: Motor Rated Current”.

· The specifications of the motor are generally specified according to the combinations of the rated voltage, rated frequency and rated current.

【 For example】380V／50Hz／1.0A，400V／60Hz／1.5A

The rated voltage should be set only after the power voltage in practical use input to the inverter MK300 had been selected.

Moreover, the rated current varies with the rated voltage and the rated frequency, be sure to set them after the combination had been confirmed.

77

4. Operation Method (Basic & Trial Operations)

3. Setting of Motor Constants

Be sure to perform the auto-tuning after the specifications of motor had been set.

· Do not connect loads to the motor shaft during auto-tuning. It is suggested that it should be done in the standalone status.

STOP

button on the operation panel to reset, and then restart the inverter.

② For the operation in external control mode (parameter P003 is set to “2” or“4”), turn off the OPERATION COMMAND button designed for external control once to reset, and then restart the inverter.

Note: Reset by stop signal cannot be made through communication.

For the operation in external control or communication setting mode

(parameter P003 is set to “3”, “5”, or “7”) , the reset cannot be made even if

OPERATION COMMAND button designed for external control or communication is turned OFF once.

Press

STOP button on the operation panel to reset, and then restart the inverter.

6. Maintenance and Inspection

6.1 Safety Precautions

Wait at least five minutes after turning off the input power before starting the maintenance and inspection work.

Failure to do so may result in electric shock.

Maintenance, inspection and part replacement work must be done only by qualified persons.

(Remove metal articles such as watch, bracelet(s) etc. before operation.)

(Please use insulated tools.)

Failure to do so may result in electric shock or injury.

Do not replace the cooling fan when power is ON. Failure to do so may result in electric shock

Employ an electrical engineering company to periodically tighten the terminal screws.

Loose terminal screws could lead to overheating or fire.

6.2 Precautions on Inspection

· To measure the insulation resistance between the power supply cable and the motor cable with a megger, always disconnect the wires connected to the inverter first before measuring. Do not make such measurement on the control circuit.

· The inverter is mainly consisted of semiconductor elements. To prevent the negative effects arising from the temperature, humidity, dust and vibration etc. in working environment and the malfunctions caused by components’ aging and service life, please perform daily inspection.

The following table shows the standard replacement interval (years) under normal working conditions (average annual ambient temperature = 30°C, load factor < 80% and average daily operation period < 12 h).

6.3 Inspection Items

1. Daily inspection: Basically check if abnormality occurs during operation.

A multimeter is normally used to check the input and output voltages of the inverter during operation.

2. Periodic inspection: To check all locations where inspection can be performed only when the inverter is stopped and where periodic inspection is required.

86

6. Maintenance and Inspection

6.4 Component Replacement

Wear-out faults are related to endurance period and service life. The endurance period largely depends on the working conditions.

1. For example, service life of relay is determined by the roughness of the contact surface.

Contact current and load inductance are the major factors affecting its service life.

2. Capacitor inside the inverter is used mainly as a smoothing filter. Due to the chemical reaction that takes place internally, its service life is greatly affected by the temperature. Generally speaking, rising of 10°C in temperature reduces the service life of an aluminum electrolytic capacitor by half, which also affects the service life of inverter.

When the inverter is used under high temperature, the aluminum electrolytic capacitor may suffer from wear-out faults prior to other components in normal status and must be replaced to extend the service life of inverter.

Rotation Direction of Timer Operation

Rotation direction at each level from the 1st to 8th speed can be set in “P301:

Multi-step Speed Function Selection” with the setting value of “3” or “4”.

“0” and “1” indicate forward run and reverse run respectively, while the 1st to

8th speed indicate different levels. After rotation direction is determined (“0”

(forward run) or “1” (reverse run)), the sum of 0 or 1 multiplied by addition value corresponding to each level can be acquired and used as the setting value.

(Refer to the following table. The sum of rotation direction (“0” or “1”) multiplied by addition value of each speed level is used as the setting value.)

■ Example of setting: The 1st speed＝forward run, the 2nd speed＝forward run, the 3rd speed＝forward run, the 4th speed＝forward run, the 5th speed＝ reverse run, the 6th speed＝reverse run, the 7th speed＝reverse run, the 8th speed＝forward run

Appendix Function Parameter List

PID control is a control method enabling the feedback value (measured value) to be consistent with the set target value. In MK300, PID control can be applied after the setting values of P118, P101 to P106 are changed to “10(r10)”. Related parameters of PID control: P345 to P356.

■ P Control (Proportional Control)

Output the operation amount (output frequency) that is in direct proportion to the deviation.

■ I Control (Integral Control)

Output the operation amount (output frequency) of the deviation integral. Which can be used to effectively control the consistence of the feedback value and the target value, however, a sharp change cannot be traced.

■ D Control (Derivative Control)

It is controlled via the value, which is obtained by derivative (slope deviation) multiplied by the time constant, to judge the deviation of the signal. Transient characteristics such as overshoot or vibration can be reduced through the derivative control.
