Chapter 2 Wiring of System 3

The capacity of the circuit breaker shall be 1.5 ~ 2 time of the rated current of the drive. The time features of the circuit breaker shall fully consider the time features of the drive overload protection.

Leakage circuit breaker

Because the drive output is the high-frequency pulse voltage, there will be high-frequency leakage current. Specialized leakage circuit breaker shall be installed at the input end of the drive. B type leakage circuit breaker is suggested, and the leakage current value shall be set as 300mA.

Contactor

Frequent open and close of contactor will cause drive failure, so the highest frequency for the open and close of contactor shall not exceed 10 times/min. When braking resistor is used, to protect the braking resistor from over-heat damage, thermal protection relay shall be installed to control the disconnect of the contactor at power supply side

Input AC/DC reactor

The drive power supply capacity shall be more than 600kVA or 10 times of the drive capacity. If there is switch type reactive-power compensation capacitor or load with silicon control at the same power line, there will be high peak current flowing into drive power input circuit, causing the damage of the rectifier components. When the voltage unbalance of the three-phase power supply exceeds 3%, the rectifier component will be damaged. The input power factor of the drive is required to be higher than 90%. In case of above situations, install the AC reactor at the input end of the drive or DC reactor to the DC reactor terminal.

Input noise

The input noise filter can reduce the noise that flows from the power supply to the drive or the drive to power supply.

Thermal protection relay

Although the drive has motor overload protection function, when one drive drives two or more motors or multi-pole motors, to prevent the motor over temperature failure, thermal protection relay shall be installed between the drive and each

motor, and the motor overload protection parameter FC.00 shall be set as “0”

(motor protection disabled).

Output noise filter

When the noise filter is applied to the output side of drive, the conduction and radiation interference can be reduced.

Output AC reactor

When the cable connecting the drive and the motor is longer than 100m, it is suggested to install AC output reactor to suppress the high-frequency oscillation

NE200/300 Series Drive User Manual

to avoid the damage to motor insulation, large leakage current and frequent drive protective actions.

2.3 Attention for Main Circuit Wiring

2.3.1 Power Supply Wiring

It is forbidden to connect the power cable to the drive output terminals; otherwise, the internal components of the drive will be damaged. To facilitate the input side over current protection and power failure maintenance, the drive shall connect to the power supply through the circuit breaker or leakage circuit breaker and contactor. Please confirm that the power supply phases, rated voltage are consistent with that of the nameplate, otherwise, the drive may be damaged.

2.4 Motor Wiring

It is forbidden to short circuit or ground the drive output terminals; otherwise the internal components of the drive will be damaged. Avoid short circuit the output cable and the drive enclosure, otherwise there is the risk of electric shock. It is forbidden to connect the output terminals of the drive to the capacitor or LC/RC noise filter with phase lead, otherwise, the internal components of the drive may be damaged. When contactor is installed between the drive and the motor, it is forbidden to switch on/off the output contactor during the running of the drive; otherwise, there will be large current flowing into the drive, triggering the drive protection action. Length of cable between the drive and motor If the cable between the drive and the motor is too long, the higher order harmonic leakage current will cause impact on the drive and the peripheral devices. It is suggested that output AC reactor be installed when the motor cable is longer than 100m, and that carrier frequency be set as follows:

2.4.1 Grounding Wiring

The drive will produce leakage current. The higher the carrier frequency is, the larger the leakage current will be. The leakage current of the drive system is more than 3.5mA, and the exact value of the leakage current is determined by the site conditions. To ensure the safety, the driver and the motor must be grounded. The grounding resistance shall be less than 10ohm. For the grounding wire diameter requirement, refer to 8.7 Model selection of system Do not share grounding wire with the welding machine and other power equipment. Cable length

2.4.2 Countermeasures against conduction and radiation interference

Fig.2-2 Countermeasures for Conduction and Radiation Interference

When the input noise filter is installed, the wire connecting the filter to the drive power input terminal shall be as short as possible. The filter enclosure and mounting cabinet shall be large area reliably grounded to reduce the back-flow impedance of the noise current Ig. The wire connecting the drive and the motor shall be as short as possible. The motor cable adopts 4-core cable, among which the grounding wire shall be one end grounded at the drive side, the other end connected to the motor enclosure. The motor cable shall be sleeved into the metal tube. The input power wire and output motor wire shall be kept away from each other if possible. The equipment and signal cables vulnerable to interference shall be kept far away from the drive. Key signal cables shall adopt shielding cable. It is suggested that the shielding layer shall be grounded with 360-degree grounding method and sleeved into the metal tube. The signal cable shall be kept far away from the drive power input wire and output motor wire. If the signal cable must cross the power input wire and output motor wire, they shall be laid orthogonal. When analog input of voltage or current is adopted for remote frequency setting, twisted shielding cable shall be used. The shielding layer shall be connected to

4.1.3 Digital display zone

It is four-digit LED display. Be able to display setup frequency, output frequency, various monitoring data and alarm code

4.2 Function code viewing and modification

The keypad of the NE200/300 drive adopts three levels menu structure to carry out operations such as parameter setting. The three levels are: Groups of function code (level-1 menu) Function code (level-2 menu) Function code setup value(level-3 menu)

Note:

At level 3 menu, pressing PRG key or ENTER key can return to level-2 menu. The difference between them is that: Pressing ENTER will save the setup and return to the level 2 menu and then automatically shift to the next function code; while pressing PRG key will directly return to level 2 menu without saving the parameter, and stay at current function code. Below is the example of modifying the function code F9.01 from 10.00Hz to

20.00Hz. (The number of bigger font size refers to the blinking digit),

Fig.4-2 Example of 3 levels menu operating

At level-3 menu, if the parameter has no blinking digit, it indicates that this function code cannot be modified. The possible reasons include:

1) The function code is an unchangeable parameter, such as actual detection

parameter, running record parameter, etc.

2) The function code cannot be modified in running status. It can be modified

only after the drive running is stopped.

Displaying status include the stopped state parameter display, the running status parameter display, the function code edition display and the fault warning condition display etc.

1) The stop status parameter display

The drive is at stop state. The LED displays the stop state parameters. You can press “>>” to by turns display different parameters at stop state. (User can set which parameters are to be displayed at stop state in FE group function codes.)

2) The running state parameter display

The drive is running and the LED displays the running state parameters. You can press “>>” to display by turns the different running state parameters. (User can set which parameters are to be displayed at running state in FE group function codes.)

3) Fault and warning state

If the drive has detected a warning signal, it comes into warning state and blinks the warning code. If the warning signal disappeared, the warning code will automatically disappear. If the drive has detected an error, it comes into fault state and show the fault code steadily. And the indicator TRIP will light on. By pressing the “>>”key, user can view the parameters value of stop state. If you want to see the details of fault

information, press the “PRG” key to enter programming state and check

parameter group FF. User can reset the drive by STOP key, terminal or communication. If the fault signal still exists, the keypad keeps displaying the fault code.

4) Function code setting state

No matter it is under stop state, running state or warning/fault state, it is valid to press PRG key to enter parameter setting. The detailed setting method is instructed in this manual section-4.2.

4.4 Password Setting

The drive provides user password setting function. When FP.00 is set to non-zero value, which is the user password, the password protection turns valid after exiting the editing status. When the user goes to FP group again and

presses ENTER, it shows “0000”. Correct password should be input to unlock the

protection status to enter FP group again. To disable this password protection, user need to input the correct password first and then change FP.00=0.

4.5 Typical application

4.5.1 Open loop synchronizer debugging

1 To set the motor rated frequency (F0.10), motor type (F5.00=2), motor

rated power (F5.02), Polarity number (F5.01, it can be unset, but the rotate speed will not be accurate), rated current(F5.03) according to the motor nameplate.

2 To set the max/upper limit frequency (F0.11/F0.12) according to

working conditions. 3 To set the driver as open-loop vector control. (F0.01=1) 4 Tuning motor: Set F5.10=2 as rotary tuning, when the driver displays

“-At- “on screen, press “RUN” button to start tuning.

NE200/300 Series Drive User Manual

Chapter 4 Operation and application 31

The driver will automatically save synchronous motor parameters F5.11~F5.14. When the motor is on rotary tuning, it must be noted that the acceleration and deceleration time are F0.19 and F0.20, which cannot be set too small. If rotary tuning is not allowed on site, static tuning(F5.10=1) should be conducted, the synchronous motor counter EMF shall be set manually

(F5.14). Note：There are two commonly used method to represent the synchronous motor counter EMF.

a) Volt per thousand rotation b) Rated frequency corresponds to the amount of voltage

NE series invertors uses the second representation. Note: when the motor is on rotary tuning or running, the motor occurs

unstable vibration, skip flow fault, current limiting fault, then need to turn down the current loop parameter properly.

4.5.2 Closed loop debugging

Incremental encoder parameters(F3.46=1)

1) To set some motor related parameters, like the motor type, rated power, rated current, motor polarity, rated rotation speed and so on according to motor nameplate.

2) To set encoder pulse number (F3.14), PG direction (F3.16), F3.54, F3.55, F3.56.

3) To set the control mode as closed-loop control mode (F0.01=2)

4) Waiting for the rotary tuning completed (if the encoder with Z signal, users do not have to set the encoder pulse, encoder direction related parameters, these parameters can be gotten from rotary tuning, but need to set the related function of parameter.

Resolver encoder(F3.46=3)

1) To set some motor related parameters, like motor type, rated current, motor polarity, rated rotation speed and so on according to motor nameplate.

2) To set the related parameters of resolver encoder. F3.47~F3.50.

3) To set the control mode (F0.01=2) as closed-loop control mode

4) Waiting for the rotary tuning completed.

Note:

a) The internal driver rated slip is calculated from the synchronous speed

of the motor (120*f/P)-rated rotation speed, so the set rated rotation speed should be lower than motor synchronous rotation speed.

b) When there is no Z signal in the encoder of asynchronous motor, the

encoder pulse can be set and run to 50Hz with an open loop to check the motor rotation speed and the running direction of encoder and motor.(F3.62=0 means same direction. F3.62=1 means that the

NE200/300 Series Drive User Manual

32 Chapter 4 Operation and application

direction between encoder and motor is reverse, you can set F3.16 or exchange the A/B wires to make it reverse.)

c) As to the 24V differential PG option, when the encoder is

non-differential, it can short connect the PG option terminals 24V,A+,B+, and the encoder terminals, A/ B/ Power/ Ground, should be accordingly connected to PG option’s terminals, A-/ B-/ 24V/ COM (or short connect PG option’s terminals, COM/ A-/ B- , and encoder terminals, A/ B/ Power/ Ground, short connect to PG card terminals A+, B+,24V, COM, which is mainly determined by the type of encoder.

4.5.3 DC common bus

A part of drivers of NE200/NE300 can share DC common bus, please to contact our technic support engineer if you want to share DC common bus. While sharing bus, the master driver is AC-in and AC-out, connect the DC bus of the slaver driver to the DC bus of the master. Warning! Usually, the power of the slaver driver can ‘t be more than the 15% of the power of the master driver

because the rectifier and capacitor’s capacity limitation of the master driver.

The proportional gain (KP) is the parameter that decides the sensitivity of P action in response to the deviation. The bigger the proportional gain KP is, the more sensitive the system acts and the faster the drive responses. However, oscillation may easily come into being and regulation time extends. When KP is too big, the system tends to instability. When KP is too small, the system will slow, and responses lag. Use integration time to decide the effect of integral action. The longer the integration time, the slower the response, and the worse the ability of control external disturbance variation. The smaller the integration time is, the stronger the integral take effect. The smaller integration time can eliminate the steady state error and improve control precision, fast response. However, oscillation may easily occur, and the system stability decrease, if the integration time is too small. Differential time define the effect of differential action. The bigger differential time can attenuate the oscillation caused by P action more quickly when deviations occurs and short the regulation time. However, if differential time is too big, oscillation may occur. If the differential time is small, the attenuation effect will be small when deviations come into being and the regulation time is longer. Only the right differential time can reduce regulation time.

The two parameters are used to limit the output range of the PID regulator. When PID regulating is set to be the frequency reference, user can adjust the negative limit of the PID for reverse control, e.g. setting F8.17=30.00Hz to limit the reversed rotation within 30Hz. When PID and other channels are combined as frequency reference, the PID positive and negative limit can be adjusted according to actual application needs. For example, when PID and AI1 is overlapped to be frequency reference, and if system requires PID to conduct fine adjust of ±5V based on AI1, both F8.16 and F8.17 are to be set as 5.00Hz.

The preset length (PB.00), actual length (PB.01) and number of pulse per-unit (FB.02) are mainly used for fixed-length control. The length is calculated via the pulse signal input by the discrete input terminal, which needs to set the corresponding input terminal to length count input terminal. And input terminal X4 or X5 is usually used when the pulse frequency is relatively high. Actual length = counted terminal input pulse number ÷ number of pulse per unit. When the actual length FB.01exceeds the preset length FB.00, the multifunction digital output terminal defined as “length arrival terminal” will output ON signal.
