3.2 Description of Peripheral Devices for Main Circuit

Circuit breaker

Leakage circuit breaker

Contactor

Input AC reactor or DC reactor

Input noise filter

Thermal protection relay

Output noise filter

Output AC reactor

The capacity of the circuit breaker shall be 1.5 ~ 2 times the rated current of the inverter.

The time features of the circuit breaker shall fully consider the time features of the inverter overload protection.

Because the inverter output is the high-frequency pulse, there will be high-frequency leakage current.

Special leakage circuit breaker shall be used when installing leakage circuit breaker at the input end of the inverter.

It is suggested that B type leakage circuit breaker be used, and the leakage current value shall be set as 300mA.

Frequent open and close of contactor will cause inverter failure, so the highest frequency for the open and close of contactor shall not exceed 10 times/min.

When braking resistor is used, to void the over temperature damage of the braking resistor, thermal protection relay with braking resistor over temperature detection shall be installed to disconnect the contactor at the contact control power side of the thermal protection relay.

1. The inverter power supply capacity is more than 600kVA or 10 times of the inverter capacity.

2. If there is switch type reactive-load compensation capacitor or load with silicon control at the same power node, there will be high peak current flowing into input power circuit, causing the damage of the rectifier components.

3. When the voltage unbalance of the three-phase power supply of the inverter exceeds 3%, the rectifier component will be damaged.

4. It is required that the input power factor of the inverter shall be higher than 90%.

When the above situations are present, install a AC reactor at the input end of the inverter or DC reactor to the DC reactor terminal.

The noise input from the power end to the inverter and output from the inverter to the power end can be reduced.

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

P9.16 shall be set as “2” (motor protection disabled).

When the output end of the inverter is connected with noise filter, the conduction and radiation interference can be reduced.

When the cable connecting the inverter and the motor is longer than 100m, it is suggested to install

AC output reactor to suppress the high-frequency oscillation to avoid the damage to motor insulation, large leakage current and frequent inverter protective action.

3.6 Attention for Main Circuit Wiring

3.6.1 Power Supply Wiring



It is forbidden to connect the power cable to the inverter output terminal, otherwise, the internal components of the inverter will be damaged.



To facilitate the input side over current protection and power failure maintenance, the inverter 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 inverter may be damaged.

3.6.2 Motor Wiring



It is forbidden to short circuit or ground the inverter output terminal, otherwise the internal components of the

SY8600 High Performance Vector Control Inverter User Manual inverter will be damaged.



Avoid short circuit the output cable and the inverter enclosure, otherwise there exists the danger of electric shock.

It is forbidden to connect the output terminal of the inverter to the capacitor or LC/RC noise filter with phase lead, otherwise, the internal components of the inverter may be damaged.



When contactor is installed between the inverter and the motor, it is forbidden to switch on/off the contactor during the running of the inverter, otherwise, there will be large current flowing into the inverter, triggering the inverter protection action.



Length of cable between the inverter and motor

If the cable between the inverter and the motor is too long, the higher harmonic leakage current of the output end will cause adverse impact on the inverter and the peripheral devices. It is suggested that when the motor cable is longer than 100m, output AC reactor be installed. Refer to the following table for the carrier frequency setting.

Length of cable between the inverter and motor

Carrier frequency (PA.00)

Less than 50m

Less than 15kHz

Less than 100 m

Less than 10kHz

More than 100m

Less than 5kHz

3.6.3 Grounding Wiring



The inverter will produce leakage current. The higher the carrier frequency is, the larger the leakage current will be. The leakage current of the inverter system is more than 3.5mA, and the specific value of the leakage current is determined by the use conditions. To ensure the safety, the inverter and the motor must be grounded.



The grounding resistance shall be less than 10ohm. For the grounding wire diameter requirement, refer to 3.3 lectotype of main circuit peripheral devices.



Do not share grounding wire with the welding machine and other power equipment.



In the applications with more than 2 inverters, keep the grounding wire from forming a loop.

Fig. 3−3 Grounding wiring

3.6.4 Countermeasures for Conduction and Radiation Interference

SY8600 High Performance Vector Control Inverter User Manual

Fig.3−4 Noise current illustration



When the input noise filter is installed, the wire connecting the filter to the inverter input power end shall be as short as possible.



The filter enclosure and mounting cabinet shall be reliably connected in large area to reduce the back flow impedance of the noise current Ig.



The wire connecting the inverter and the motor shall be as short as possible. The motor cable adopts 4-core cable, with the grounding end grounded at the inverter 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 as long as possible.



The equipment and signal cables vulnerable to influence shall be kept far away from the inverter.



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 inverter input wire and output motor wire. If the signal cable must cross the input wire and output motor wire, they shall be kept orthogonal.



When analog voltage and current signals are adopted for remote frequency setting, twinning shielding cable shall be used. The shielding layer shall be connected to the grounding terminal PE of the inverter, and the signal cable shall be no longer than 50m.



The wires of the control circuit terminals RA/RB/RC and other control circuit terminals shall be separately routed.



It is forbidden to short circuit the shielding layer and other signal cables or equipment.



Parameter setting method via panel: through three-level menu, users can look up and modify the function codes very easily.

Three level menu structure: function parameters (first level)→function codes(second level)→value of function code(third level). Operation process is shown in Fig.4-1.

Fig.4-1

Menu Operation Procedure

In the third level menu, user can return second level menu by pressing

PRG

key or

SET key. The difference is: Parameter settings can be saved in control board if SET key is pressed, then LED returns to second level menu and shifts to next function code automatically; If user presses

PRG

key, LED returns to second level menu directly, but the parameters cannot be saved and stop at current function code.

4.5.2

Parameter setup

Setting parameters correctly is a premise for actualizingSY8600’s performances.

Parameter setting method via panel will be introduced in the following part with rated power as an example (Change 18.5kW into 7.5kW).

Operation process is shown in Fig.5-2. Press the SHIFT key with single direction shifting function to shift the flashing bit of parameters (that is modification bit). After finishing the parameters setup, press the MENU key twice to exit programming state.

4.6 Parameter Display

In stopping state or running state, various state parameters can be displayed by

LED. The displayed parameters can be decided by PH.00 ~ PH.01 and can be scrolled through by pressing the

SHIFT

key. The following is an explanation for the parameters operation method in stopping and running state.

4.6.1

Switch of Parameter Display in Stopping State

In stopping state, the drive has 9 state parameters which can be scrolled by

SHIFT key, they are: frequency setting, external counting value, digital value input terminal state, digital value output terminal state, panel potentiometer, analog input AI1, analog input AI2 and DC bus voltage. Please refer to the explanation of PH.01.

The default value of PH.01 is "preset frequency". If PH.01 value is set to 2, default display parameter in stopping state will be changed into "DC bus voltage".

User can look up other parameters during stopping state by pressing SHIFT key:

Everytime you press

SHIFT

key, the next parameter in stopping state will be displayed.

4.6.2

Switch of the running parameters

In running state, maximum 15 running state parameters can be displayed by SY8600 drive via

SHIFT

key.

4.7 Motor auto-tuning procedure

Before selecting vector control mode, user should input motor parameters correctly.

SY8600 drive can get motor’s standard parameters according to the parameters on nameplate; In order to get better control performance, you can control the drive to perform auto-tuning on the motor, so as to get accurate motor parameters.

Parameter tuning can be done through P3.05.

S et F0.01 parameter to 0 to select panel running command control mode;

2. According the motor’s name-plat, Set P3.00、P3.01、P3.02、P3.03、P3.04 parameter in proper order。

3. Set P3.05 to1，Select static auto- tuning，Or set P3.05 to 2，Select overall auto- tuning ，Press“SET”key。

4. Press RUN key to start motor auto-tuning, After tuning, the motor stops.

When P2.29=0, this function is disabled. In this case, terminal F/R=OFF, Run FWD; terminal F/R=ON, Run Rev;

When P2.29=1, this function is enabled. In this case, terminal F/R signal is invalid. Motor can only run forward, and switching between FWD/REV is not available.

Running mode of routine program is independent of this function.

SY8600 High Performance Vector Control Inverter User Manual

In traverse operation mode, both FWD and REV running are allowable, but switching between FWD/REV is prohibited. Setting FWD/REV direction may not be same as actual direction, which can be defined by changing phase sequence of the output.

P2.30 Carrier frequency adjustment

Setting range:2.0～12.0KHz

Carrier wave frequency can be continuously adjusted within 2.0~12.0KHz.

This function is mainly used to improve system performance, and reduce noise and vibration.

Since SY8600 series adopts IGBT as power devices, carrier frequency can be higher. Increasing carrier frequency can bring following benefits: better current waveform, lower noise, which is especially suitable for applications that need low noise. However, with the increase of carrier frequency, it also brings some disadvantages, such as increase of power loss on switching devices, overheat, low efficiency, etc. Since high frequency carrier produces severe radio interference, please install filter for application with high requirement on EMI. At the same time, capacitive leakage current increases, and the wrong action of leakage protector and over current may happen.

Decreasing carrier frequency, the contrary is the case. Motor noise will increase in lower carrier frequency. Influence of carrier frequency is different for various motors. Therefore, optimal carrier frequency should be selected according to practical situation. In fact, with the increase of motor capacity, carrier frequency should decrease. For motor capacity above 37 kW,

2KHz carrier frequency is recommended.

P2.31 Zero frequency threshold

P2.32 Zero frequency hysteresis

Setting range: 0~400.0Hz

The above two parameters are to set zero frequency hysteresis control.

Take analog input AI1 for example, see Fig.6-10:

Startup process:

When the Run command is issued, only afterAI1 voltage arrives or exceeds VS-b, does the drive start and accelerate to the preset frequency in defined Acc time.

Stop process:

During Dec process, when AI1 voltage reduces to VS-b, the drive will not stop until it reaches VS-a and the corresponding frequency becomes fa, where fa is the threshold of zero frequency defined by P2.31, and fb, fa is defined by P2.32.

This function can realize dormancy to save energy, in this way, frequent start and stop at threshold frequency can be avoided.

If the integral time is set to 0 (P5.01=0, P5.03=0), which means integral function is disabled, and the speed loop is simply a proportion regulator. a. Adjustment of proportion gain P and integration time I for speed regulator

Increasing P will fasten system transient response, but system oscillation may occur given too big P. Decreasing I will fasten transient response, but system oscillation and overshoot may occur given too small.

Normally, user may tune P first, increase its value as long as no system oscillation occurs; then adjust I, ensuring fast response without overshoot. Figure 6-15 shows better speed step response if P, I are set properly. Speed response can be monitored through analog terminals AO1 and AO2. Refer to P8 parameter group for detail information.

SY8600 High Performance Vector Control Inverter User Manual

Note: a. With improper PI parameters, after accelerating to high speed, over-voltage during Dec process may occur (Without external braking resistor or unit), which is caused by regenerative braking after speed overshoot. To avoid this fault, user can tune PI parameters. b. Adjustment of PI parameter in high/low speed applications

If system is required to respond quickly both in low and high frequency operation with load, user may set ASR switching frequency (P5.04).

Normally, when the system runs at low frequency, the transient response performance can be improved by increasing P and decreasing I. Adjust

ASR parameters following the procedures below:

1. Set appropriate switching frequency P5.04;

2. Tune proportional gain P5.00 and integration time P5.01 for low-speed application, and ensure no oscillation and good response performance at low frequency.

3. Next, tune proportional gain P5.02 and integration time P5.03 for high-speed application, and ensure no oscillation and good response performance at high frequency.

P5.05 Slip compensation gain Setting range:50.0～200.0%

P5.05 is used to calculate slip frequency. Setting value 100% means rated slip frequency corresponds to rated torque current. User may decrease/increase the settings of P5.05 to adjust the speed control's difference accurately.

Note:

This function is valid to open loop vector control mode. For close loop vector control mode, F5.05 can be set to 100% for most applications.

Pd.00

Motor overload protection mode

0: No protection

Setting range：0，1，2

1: Common motor protection

Since cooling conditions of common motor deteriorates at low speed, please lower the motor’s thermal protection threshold at this time.

2: Variable frequency motor protection

Since the variable frequency motor applies forced air-cooling, the protection parameters needn't be adjusted during low speed running.

Pd.01

Motor overload protection factor

Setting range：20.0%-150.0%

Heat dissipation becomes worse at low frequency, and high temperature will reduce service life of the motor. Through setting threshold of the electronic thermal overload relay, overload current and current limit will be proportionally adjusted.

When motor capacity is lower than that of the drive, this function is used provide overheat protection for the motor.

When several motors are driven by the same variable speed drive, this function is disabled. When display readings reach 100%, overload protection will be trigged

Pd.02

Over voltage stall selection

0: Disabled; 1:Enabled

Setting range：0,1

In inverter's Dec process, the actual motor speed may be higher than the output synchronized speed of the inverter due to the load inertia. At this time, the motor will feed the energy back to the inverter, resulting in the voltage rise on the inverter's DC bus. If no measures being taken, tripping will occur due to over voltage.

The overvoltage stall protection function is that during the Dec running, the inverter detects the bus voltage and compares it with the stall overvoltage point defined by

102

SY8600 High Performance Vector Control Inverter User Manual

PD.03. If the bus voltage exceeds the stall overvoltage point, the inverter will stop reducing its output frequency. When the detected bus voltage is lower than the point, the Dec running will be restored, as shown in Fig.6-32.

Setting range：0.00-99.99Hz/S

Setting range：0、1、2

Auto current limiting function is used to limit the load current under the preset current (PD.07) in real time to avoid trip due to over-current. This function is especially useful for the applications of larger load inertia or sharp change of load.

PD.07 defines the threshold for current limiting. Its setting is a percentage of drive’s rated current Ie. PD.08 defines the decreasing rate of output frequency when the drive is in auto current limiting status. If PD.08 is set too small, overload fault may occur. If PD.08 is set too big, the drive may be in energy generation status for long time that may result in overvoltage protection.

The action mode of auto current limiting function is decided by PD.09:

PD.09= 0: disabled;

PD.09= 1: auto current limiting is effective during acceleration or deceleration but ineffective at constant speed;

PD.09= 2: auto current limiting is effective during acceleration/deceleration and constant speed;

I/O status

If communication fault occurs, the drive will response fault code, and report function code or 80H to the main control equipment.

For example:

ASCII mode: RTU mode:

Slave address ‘0’

‘1’

Fault code:

01 Function code error:

Function code is invalid. In the protocol, valid function codes are: 03H,

06H or 08H.

02 Invalid data address:

Data address is invalid

03 Invalid data setting

Data value is invalid.

04 Invalid command:

In current state, the drive cannot execute this command.

09 Wrong CRC check

11 Reserved

12 Message characters of the command string is too short

13 Command string is too long, and reading string should be less than 72 characters.

14 Contains non-ASCII character, non-starting character or non-CR, LF end character.

Additional information

1. Function code conversion

If preset data is n, then sending data n = n×(1/increment) (Refer to function parameters table)

Convert data “n” into HEX number, which is 2 bytes.

2. ASCII mode LRC check

In the example above, LRC check: 01H+03H+02H+00H+00H+01H=07H, and it’s complement=F9H.

3. RTU mode CRC check

LRC check is executed from slave address to data end character, and the operation rule is shown as following:

131

SY8600 High Performance Vector Control Inverter User Manual

Step 1: Load a 16-bit register with FFFFH. Call this the CRC register;

Step 2: Execute XOR operation with the first message command and the lower byte of 16-bit CRC register, and put the result in the CRC register;

Step 3: Shift the CRC register one bit to the right (toward the LSB), and fill the MSB with 0;

Step 4: If the shifted bit is 0, save the new value of step 3 to CRC register; otherwise, execute XOR operation with A001H and CRC register, and save the result in CRC register;

Step 5: Repeat step3~4 until 8 shifts have been performed.

Step 6: Repeat step2~5 for the next 8-bit message command. Continue doing this until all messages have been processed. The final content of

CRC register is the CRC value.

Note:

When the 16-bit CRC is transmitted in the message, the low-order byte will be transmitted first, followed by the high-order byte.
