PRECAUTIONS

 Electric shock prevention:

The enclosure of the starter cabinet must be grounded properly to keep away from the electric shock even if electric leakage on the enclosure. Disconnect all power supplies before maintenance for soft starter or motor. Due to storage function of internal RC circuit, the triggering component will keep dangerous voltage even if the main power supply is cut off. Use a connection wire to short-circuit it with ground in order to discharge the voltage.

 Compensation capacitance:

The non-active power compensation capacitance is used to raise power factor must be connected to VS65 soft starter’s input terminal and not connect to the output terminal; otherwise, the soft starter’s controlled silicon power device may be damaged.

 Insulation test:

To test voltage withstanding ability of the 3-phase supply to ground, have to take off all circuit control boards. Using a M ohm meter to measure the insulation voltage withstanding of control board to ground is also forbidden.

 Low-voltage test:

The test should be strictly in accordance with operating instructions. The low voltage terminal of the voltage transformer should be disconnected.

 Input & output:

Do not make mistakes when connecting input and output terminals of the VS65 soft starter’s main loop; otherwise, there may be result in the unexpected actions of the soft starter, which could damage the starter and motor.

TRIAL RUN

 Before commissioning the softstarter, please, read section 8 of this manual

referred to power cabinet.

 Verify all parameters before operating the softstarter. Alteration of parameters

may be required depending on application and load.

 Always apply voltage and current signals to each terminal that are within levels

indicated within this manual. Otherwise, damage to the softstarter may result.

EARTH CONNECTION

 Connect only to the dedicated ground terminal of the softstarter. Do not use the

case or the chassis screw for grounding.

 When installing, grounding wire should be connected first and removed last.

 The earth cable must have a minimal cross sectional area that meets local

country electrical regulations.

 Motor ground must be connected to the softstarter ground terminal and not to

the installation’s ground. We recommend that the section of the ground connection cable should be equal or higher than the active conductor.

 Installation ground must be connected to the softstarter ground terminal.

1.3. Design Features

The VS65 medium-and high-voltage (3300~15000V) soft starter consists of two cabinets: one is the power cabinet with main vacuum circuit-breaker, and the other is the softstarter cabinet. Both parts are described below:

 Main Vacuum circuit-breaker

The main vacuum circuit-breaker on the power cabinet allows that the motor can be started or stopped with the load. The switch should be with the protection for the short circuit. Regarding the designed maximum value, the 5kV main vacuum circuit-breaker is used for the 2300~4160V soft starter, the 7.2kV one is used for the 6000~7200V soft starter, and the 15kV one is used for the 10~14kV soft starters.

 Soft starter

The soft starter part consist of the bypass vacuum contactor, controlled silicon component, RC absorber circuit, trigger circuit, and the controlling part, etc.

o Bypass vacuum contactor:

After the soft starter fishing the motor starting, the contactor will be closed and allow the motor current to supply through the bypass contactor. Regarding the used voltage ratio, the 5kV is used for 2300V and 4160V, the 7.2kV is used for 6000V and 7200V, and the 15kV is used for 10kV and 15kV soft starters.

INTRODUCTION

POWER ELECTRONICS

o RC absorber circuit:

It provides instantaneous voltage protection circuit in order to reduce dV/dt surge voltage and prevents the damage into the silicon controlled component.

o Trigger circuit:

It provides over 2A trigger pulses to ensure the dynamic voltage to be distributed between the silicon controlled in series and in parallel stably. Both the trigger circuit and the controlled silicon will be at the high voltage, which are separated from the control board and the transformer by optical fibers.

o The controlled silicon high-voltage component are arranged in parallel and in series, the

practical quantity is depending on the motor’s voltage.

1.4. Operating Principle

The VS65 has a micro CPU as its control core that can start up and protect the motor. The CPU can control and trigger the phase angle of SCR in order to reduce voltage applied to motor, and at next step, by regulating the voltage and current applied on the motor slowly so that the motor torque can be increased smoothly till the motor runs at full speed after acceleration ramp. The starting mode can reduce the surge current at motor’s starting stage, decreasing impact on the electrical grid and the motor itself. Meanwhile, it also can reduce the mechanical impact to the device, increasing the equipment’s service life and avoid some fault and breakdown.

VS65 series can provide 3 types of starting mode:

 Voltage ramp starting mode:

 Current-limited starting mode:

The voltage ramp with current-limiting function is the factory configuration and the most reliable starting mode that meets the most requirements. The initial torque should be set at a value that just can drive the motor with the load to start. And then the voltage will be rise smoothly, within a specified ramp time and starting current range till the motor runs at the fullspeed.

During the starting, the current is increased to the specified value rapidly till the motor runs at the full speed.

INTRODUCTION

VS65

POWER ELECTRONICS

 Heavy load starting mode:

The mode is used mainly in some applications where the motor drives the loads with big inertia such as the fan, the ball mills, etc. The function can increase 8 seconds to alternative the bypass circuit in order to avoid excessively impact current due to too earlier switching.

Figure 1.1 Block diagram

1.5. Protection for Motor and System

VS65 soft starter series provides protections for the soft starter and for the motor. These protections are:

 3-phases input loss protection: the motor will only start at 3-phases input supply.  Over temperature protection: this is due to the softstarter startup frequently, that will be resulted in

the controlled silicon working at over temperature (up to 85℃)

 Over starting time protection: if the starting time is too long to damage the softstarter and the

motor. The maximum value of starting time is up to 120s.

 The softstarter can cut off the output of controlled silicon during the starting or switch off the

bypass vacuum contactor after starting in order to protect the motor. Meanwhile, by the external detection input (e.g. overload, phase input loss, etc.), these will cut off the power supply.

2. INSTALLATION AND CONNECTION

2.1. Acceptance and Unpacking

VS65 is usually transported upright. For the shipment abroad, the equipment may be placed horizontally in a container.

Unpack the goods carefully and check for any damage taken placed during the transportation. In case of damaged, please fill in a damage report within 15 days of reception of delivery order.

Confirm the received shipment accord with the ordered model. The product model is shown on the label of the low-voltage control board.

2.2. Initial Inspection

Check whether there is damage during transportation and handling.

Check whether there is the loosen parts, broken wires, or loosen connections phenomenon during the transportation and handling. The loosen connections should increase impedance and affect the performance.

Before startup, please check and confirm the rated voltage and the rated current.

2.3. Operating Environment

The proper installing location can ensure its normal running and service life. VS65 softstarter must be installed in an environment meeting these requirements:

 Operating temperature: 0~50℃ (32°F-122°F) (running at -20℃ is acceptable if there is the

heating resistance) against rain and moisture.

 Humidity: 5~95% non-condensing.  Keep away from the metal scraps, conductive dusts, and corrosive gases.  Oscillation (less than 0.5G).

2.4. Power Connections

Connect the 3-phase medium voltage power lines to the equipment’s input terminals L1, L2, and L3. Connect the three phases of motor to the output terminals U, V, and W. The copper bars or the cable must be complied with the standard of the current capacity and the voltage isolation.

WARNING

Pressing the “Stop” button does not means to cut off the power supply, there is still high voltage applied to the AC main loop. Prior to maintenance, it is necessary to switch off the main power supply, i.e. turn off the main vacuum circuit-breaker, and put it at the test position. The WARNING sign should be adhered on the panel of control cabinet and complied w ith the local electrical regulations. It is forbidden to connect a capacitance power-factor compensator with the output of VS65, otherwise will be resulted in the impact current that may damage SCR during startin g. Do not connect a capacitor to the output of soft starter. If PFC (power-factor compensa tor) is necessary, please contact with the manufacturer. To avoid the wrong connection of the input and output terminals; otherwise the logic control circuits will be damaged.

2.6. Connection and Usage of Control Terminals

2.6.1. Preparations for connection

If the user intends to use the external terminals, we suggest using a shielded wire leading out from the terminal, the shielded should be connected to the ground.

To prevent electro-magnetic interference, the control cable should be kept away from motor’s cables and other inductive devices.

2.6.2. Connection of relay output terminal

 Bypass relay terminals

After the starting process is finished, the inside contact will be closed, the bypass contact KM will be closed; when the stop instruction is order, the inside contact will be opened (See Fig

2.1).

Figure 2.1 J11 Connector wiring

 Fault output terminals

The inside contact can be programmed. It is normally-open at factory setting and can be set to normally-closed through programming. The contact has capacity of AC 250V 5A.

 Interlocking relay output terminals

These contacts are mainly used when the device is interlocked with other equipments. It may be programmed to select status. See 4.3.6 contact capacity AC 250V 5A; external control input terminal J2

 Emergency stop input terminal

They are used for the external fault signal input. Only be closed, the starter can run. When they are opened, the starter will stop. The user may program to no use the function.

 Control terminal (Stop), (Starting), (Common terminal)

The three terminals are to be connected to external startup and stop buttons. They need to be programmed.

Fig 2.2 shows the three-wire connection method.

POWER ELECTRONICS

INSTALLATION AND CONNECTION

Page 21

POWER ELECTRONICS

But the two-wire connection should be practiced for the cases below (See Fig 2.3).

1. When the customer needs only a switching contact to control starting and stop of softstarter, like the control contact J of PC/PLC.

2. When the delay function of soft starter is used, when J is closed and after a certain delay, the starter begins starting. The delay value can be set by programming (See 4.3.3 for details).

 Analogue current signal output (4～20mA)

This is used to the proportional 4~20mA current signal of main loop, with the proportional output current can be selected by programming (See 4.3.9).

 Operational power supply terminal

Provides power supply 110~220V (AC 50Hz) by a voltage transformer usually.

 Field bus terminal

MODBUS RTU and PROFIBUS share the terminal. It is necessary to select the protocol while ordering the softstarter. See Chapter 7 for the communication protocol.

4.3. Function Code Explanations

4.3.1. Code 00 – Pickup voltage. Code 01 – Rise time

They are starting control parameters under the voltage mode. Increasing the pickup voltage can help to overcome the static-friction force during the starting; if bigger load inertia, you have to set a longer rise time (as shown in Figure 4.2).

Figure 4.2 Starting ramp

VS65

4.3.2. Code 02 – Shutdown time

The shutdown time of 0 second means the free stopping. Excessive shutdown time maybe cause the system is instable. (See Figure 4.3).

POWER ELECTRONICS

Figure 4.3 Stop mode

4.3.3. Code 03 – Starting delay

This is the duration from the moment while the remote startup is closed (two-wire type) until the softstarter begins running. To use this function, the Code 09 must be set to 1. While the remote control terminals RUN, STOP, and COM are connected and the countdown value is 0, the softstarter will startup.

4.3.4. Code 04 – Limiting current

To use the function, Code 08 must be set to 0. The starter will begin starting with starting current below the set value (150%~500%). When the starting is finished, the current will drop below the rated value. If the value is larger, the allowed starting time is shorter.

Figure 4.4 Limiting current

PROGRAMMING KEYBOARD

POWER ELECTRONICS

4.3.5. Code 05 – Emergency stop setup

By setting the code 0 or 1, the user can turn on or turn off the remote emergency input. Setting 0 is disabled, setting 1 is enabled.

4.3.6. Code 06 – Interlocking delay. Code 07 – Interlocking control

The starter’s interlocking output is controlled by programming these two values. The set value of Code 06 represents the delay time from the moment when the starter startup until the terminals is closed. The code 07 can be assigned a control method of interlocking relay. See table on section

4.2. Code 07 must be 0 if delay.

0 1 2 3 4 5 6 START ● ● ● RUN ● ● ● ● STOP ● ● ● DELAY ●

Note: Marked as “●” means “Interlock” relay is closed

VS65

4.3.7. Code 08 – Starting mode

If set to 0, it means the current mode. See 4.3.4 for starting limiting current.

If set to 1, it means the voltage mode. See 4.3.1

If set to 2, it means the heavy load mode.

4.3.8. Code 09 – Control mode

0: Only the keys RUN and STOP can be used to control startup and shutdown.

1: Remote control. Only RUN/STOP by two-wire or three-wire.

2: Keyboard + Remote control (applicable for the three-wire control method) Both keyboard and remote control can be operated, but only the STOP-COM is closed, the “RUN” key of keypad can be valid,

3: PC is operated by communication bus to control and monitor.

4: Keyboard + PC: Both keyboard and communication bus is valid.

Note: The analogue current is proportional to the actual load and the maximum value is 20 mA (or 10 mA) of output current.

Ix: the measured current value (mA), D: the motor load current (%)

0 1 2 3

4.3.10. Code 11 – Display mode

0: the Current displayed is shown as the percentage of the rated current value of softstarter, i.e. 100% represents the rated current of softstarter.

XXX: the rated current of motor is setting between 1 and 1000, meanwhile the actual output current value is displayed on the LCD.

4.3.11. Code 12 – Fault relay setting

The user may set the fault relay’s status to normal-open (0) or normal-closed (1).

4.3.12. Code 13 – Tributary address

This is used to set the slave address of field bus. For the same master, the slave address will be unique. Refer to Field Bus Communication in Chapter 7.

4.3.13. Code 14 – Restart

When the starter is stopped due to the fault, setting Code 14 to 1 can cause the starter automatically running after 6s delay. If it is set to 0, the starter can only be restarting after reset. The function is only valid in the two-wire method.

4.3.14. Code 15 – Communication bus

It allows selection of communication bus between 0: MODBUS and 1: PROFIBUS.

4.3.15. Code 16 – Communication speed

This is used for selection of communication speed by MODBUS communication, the possible rang is from 300 to 19.2k bps. See 7.2 for information on usage.

4.3.16. Code 17 – Even-odd check

This is used for selection of check method by MODBUS communication. It should be in accordance with the master device.

4.3.17. Code 18 – Bbus mode

This is used in PROFIBUS, with 0 for Method 1 where parameters modification is allowed and 1 for Method 2, where only starter monitoring is performed. Refer to 7.1.

4.3.18. Code 19 – Bus fault

In case the communication control is selected, when the communication bus connection is faulted (connection failure), the starter may choose a status between: 0: only alarm without stop; and 1: stop with alarm.

4.3.19. Code 20 – RET terminal control (not be used)

VS65

RET: This terminal is multifunctional. When set to different values, the code has different functions as described below:

0: Used as a remote reset terminal, the same RST function as the STOP key on keyboard;

1: Locks remote control terminals RUN and STOP, which means when RET terminal is connected to the COM terminal, RUN and STOP will be disabled from controlling starter.

2: Locks communication bus control, which means when RET terminal is connected to the COM terminal, using bus to control startup and stop of the starter is forbidden.

4.3.20. Code 21 – Language

It allows selection of the user language. User can select English.

4.3.21. Code 22 – Invary void

According to the load type, the user can set a fixed voltage value during the starting period of motor. Once elapsed the time set in code 23, the voltage will be increased at certain ramp.

4.3.22. Code 23 – Invary time

According to the load type, the user can set the time value for keeping a fixed voltage during the starting period.

4.3.23. Code 24 – Write protection

5.2. High-Voltage Trial Run

Set up connections for the main loop according to 2.4. Since the soft starter’s incoming lines do not have section breakers, it is necessary to power on the cabinet by using the main circuit-breaker on the incoming cabinet. Prior to providing medium-voltage current, the user must check and confirm all connections are correct and the cabinet door is closed.

Based on the motor load at the field, the user should adjust various parameters of the soft starter, allowing the motor to obtain the optimum starting torque.

When pressing Key RUN, check and find whether the motor is revolving according to requirement. For any abnormal conditions, press Key STOP to shut down. If the motor does not revolve, raise the pickup voltage to increase the starting torque.

In case of faults during running, identify the reason by referring to 6.2. Pressing Key STP or closing the external control terminal RET can perform a reset.

5.3. Data Display in Running

7. COMMUNICATION PROTOCOL

The customer can select the protocol between Modbus and Profibus when placing orders. In case of choosing communication bus controlling, the function code 09 must be set to 04, 05, or 06 to activate the communication function.

7.1. Profibus Protocol

The device uses Profibus-DP to implement the communication function. The protocol standard is specified by EN50170. The Profibus communication interface has the following features:

 The Profibus performs cyclic communication rapidly;

 The Profibus supports baud rate up to 12MHz;

 Up to 125 soft starters can be controlled;

 With a Profibus debugging tool, configuring is very easy;

 The built-in Profibus communication module is very convenient in connection setup;

 All control parameters of soft starter can be set, modified by serial bus;

 The response time of data is 5ms.

Principles for quickly setup

 It is necessary to connect with the cable between the master and softstarter correctly, including

terminal resistance (for communication rate of 12M).

 The bus cable should be a shielded cable, the shielding should be connected to ground.

 The bus must be in running status;

 The softstarter must be power-on.

 The slave address (function code) of soft starter must be set correctly and consistent with that on

the master. The soft starting address must be unique.

 When the soft starter shows a fault of connection, please check the connection cable between the

master station and the softstarter, the slave address, and other parameters.

 The terminal A and B should be connected to 220ohm resistance in parallel. When multiple

devices are connected in parallel, only one of them needs to be connected with a resistance.

7.1.1. Application protocol

The Profibus controls VS65 by data blocks. There are two data areas, the Parameter Identification Area PKW and the Process Control Area PZD, occupying 2 words in input/output respectively. The former is used to read and modify starter’s function parameters and the latter is used to control and monitor status and current. The master station’s configuration is given by GSD file (See the table below).

IND: Parameter index; PWE: parameter value; STW: Control word; ZSW: Status word; ACT: Actual current value

The user may choose Type I (PPO1), which allows full operations on softstarter’s parameters and control & monitoring; when parameter modification is not necessary, Type III (PPO3) may be used.

COMMUNICATION PROTOCOL

Page 37

POWER ELECTRONICS

7.1.2. Parameter explanation

When PPO1 is chosen, function parameters of VS65 can be read and modified. The high byte (INDH) of parameter index (word) IND is task request, the low byte (INDL) is parameter address, which corresponds to the address of function code. PWE is the value of visited parameter. All values are the hexadecimal.

INDH Meaning

0 No task 1 Read a parameter at address INDL 2 Modify a parameter at address INDL; value written in PWE

INDH Meaning

0 No response 1 Pass a parameter, value in PWE 2 No right to modify 3 Task cannot be executed.

With the response of 3, the task can not be executed, the operated parameter cannot be read or written. The table below is the error types. Codes of error types are read from PWE.

3 – 15 0 Unused

Example: To start the softstarter with the slave address 02. The controller sends 02 06 00 00 00 01. If the command is executed normally, the code 02 06 00 00 00 01 will be returned. Checking the status register whether the starter started normally. If there is the fault, the code 02 06 00 00 00 04 should be sent to reset.

 Register address 40002 state register

The state register reflects the state of soft starter, which is expressed with a word.

Bit Value Description

4 – 15 Unused

Example: Reading the code of status 02 03 00 01 00 01 If the starter is in the starting process, the code 02 03 02 00 01 will be returned. If a fault occurs to the starter, the code 02 03 02 00 08 will be returned.

 40003 current average value (hexadecimal system)

The value is VS65 average value of 3-phase actual current, which is shown in percentage or actual value depending upon setting of the function code 0B.

Example: Read current value Send the code 02 03 00 02 00 01. If the current is 235A, the code 02 03 02 00 EB will be returned.

 40004 fault code (hexadecimal)

When the 3rd bit of status register 40002 is 1, VS65 is in fault status, with the fault code being consistent with 6.1.

Example: Send 02 03 00 03 00 01 If the code 02 03 02 00 04 is returned, it means there is the input phase loss (fault code 04).

 Function parameter register 40XXX of soft starter

XXX-1 is as 1YY in hexadecimal and YY corresponds to code value in table on section 4.2. For example, 108 corresponds with 08 (starting mode). Reading or writing these function codes is possible. Examples are below.

Example 1: Read the function code 04 (current-limiting value) The controller sends 02 03 01 04 00 01. The read value of function code 04 is returned. For example, 02 03 02 01 5E means the current limiting value is 350%.

Example 2: Read the function code 0C (protection level) The sent code is 02 03 01 0C 00 01. A returned code 02 03 02 00 03 is the protection level

3. Example 3: Modify the function code 04 (starting current) of soft starter to 250%.

The master sends 02 06 01 04 00 FA and VS65 returns the code 02 06 01 04 00 FA. If the code 02 86 03 is returned, it means writing is disable, possibly because the starter is running.

8.2.1.1. Basic Principle

OCDT protection, two stages

The OCDT I is valid after starting the motor and can set a delay time. It is mainly used for the short-circuit protection of the motor. Any phase current among A, B, C is larger than the setting protection value and after delay time, the device will trip at once.

Figure 8.2 Logic diagram of OCDT I protection

The OCDT II is used for the rotor locked protection of the motor. It is valid after starting the motor. The function can prevent from too long starting time and rotor locked. Any phase current among A, B, C is larger than the setting protection value and after delay time, the device will trip at once.

Figure 8.3 Logic diagram of OCDT II protection

Negative-phase-sequence over current protection

The device provide the NPS I protection to prevent the motor from phase loss, serious voltage imbalance. The NPS II protection can be used for the more sensitive current imbalance and you can select the action between warn and trip.

Figure 8.4 Logic diagram of NPS I protection

ANNEXE A. POWER CABINET OPERATION

Page 47

POWER ELECTRONICS

Overload protection

If the current of phase A or phase C (or three phases) is larger than overload setting value, then the timer is starting. The device can select the action between the warn and trip.

Thermal Overload protection

Thermal overload protection is used to prevent the motor from overheat. Considering the thermal effect of positive-sequence current (I1) and negative-sequence current (I2), we build a formula as below to simulate the process of the motor producing (Ieq) heat:

In the start-up time of the motor, K1=0.5 and after the start-up time, K 2=3 ~ 10. After the device trip, the motor is forbidden to restart until the motor has return to the cool status or press the “RES” key on the keypad.

Earth fault protection

If the zero sequence current is larger than the setting value, then the timer is starting. The device can select the action between the warn and trip.

Residual over voltage protection

The residual over voltage protection is also used to prevent the stator from the earth fault. If the zero sequence voltage is larger than the setting value, then the timer is starting. The device can select the action between the warn and trip.

Figure 8.9 Logic diagram of residual over voltage protection

Under voltage protection

If the line voltage is less than the setting value and the lasting time is longer than the setting time, the under voltage protection will be operated. The device can automatically detect PT breaking.

Figure 8.10 Logic diagram of under voltage protection

Over voltage protection

If the line voltage is larger than the setting value and the lasting time is longer than the setting time, the over voltage protection will be operated.

PT breaking protection

The device can detect the PT breaking status. If meet any conditions as below, the device will send out the warning signal after 10 seconds.

a) The max. phase voltage is less than 30V and any phase current is larger than 0.3 A b) The negative sequence voltage is larger than 8V.

Non-electric protection

The device can provide two ways of non-electric protection including temperature rising warning and high temperature trip or warn.

Warning function

Control loop breaking: checking the trip loop while the breaker is ON, and checking the close loop while the breaker is OFF. Abnormal status: detecting power loss or self-diagnose error (ROM, RAM, EPROM, etc.)

Measurement

Frequency: f Voltage: Uab, Ubc, Uca, Ua, Ub, Uc, Uzero Current: Ia, Ib, Ic, Izero Power: Active power, reactive power, power factor

Control

You can operate the breaker to trip or close at the remote control or at the manual operation by the keypad. The interval between two operations must be longer than 10 seconds.
