Installation; Safety

VLT ® Series 2000

The VLT® Series 2000 Adjustable Frequency Drive (AFD) contains dangerous voltages when connected to line voltage. Only a competent electrician should carry out the electrical installation.

WARNING

Improper installation of the motor or the AFD may cause equipment failure, serious injury or death. Follow this manual and local and national safety codes.

Caution:

The motor may start without warning during operation and programming of the parameters. Activate the STOP key on the VLT keypad when changing data.

Danfoss VLT® and CE Marking

Danfoss CE marks our VL T® Adjustable Frequency Drives (AFD) according to the Electro Magnetic Compatibility (EMC) Directive 89/336/EEC and LowVoltage Directive 73/23/EEC.

It is possible for the VLT to start upon application of AC power. DO NOT attempt any maintenance on the VLT, motor or system machinery without verifying that the AC power has been disconnected.

DO NOT touch any electrical parts after the AC line has been disconnected for at least 14 minutes. This allows for capacitor discharge.

NOTE: The STOP key on the VLT keypad DOES NOT disconnect the AC line.

It is the responsibility of the user or the person installing the AFD to provide proper grounding and branch circuit protection for incoming power and motor overload protection according to the National Electrical Code (NEC) and local codes.

Upon request we will issue a declaration of conformity to the EMC and low-voltage directives. A manufacturer's declaration for the Machinery Directive 89/392/EEC is also available.

When the installation specification is followed and shielded motor cables are used per instruction manuals provided with the drive, we guarantee the AFD complies with the EMC Directive 89/336/EEC.

Mechanical Installation

The VLT Series 2000 is cooled by natural or forced air convection. Therefore air must be able to pass freely under and over the unit

The VLT adjustable frequency drive must be mounted on a flat vertical surface.

To enable the VLT to get rid of the cooling air, you must allow free air space both above and below the adjustable frequency drive.

The ambient temperature must not exceed 40°C so that the VLT can dispose of its power loss.

CAUTION:

It is the responsibility of the user or the person installing the drive to provide proper grounding and branch circuit protection for incoming power and motor overload. National Electrical Codes (NEC) and local codes must be observed.

Prefuses

Prefuses must be installed in the AC line feeding the adjustable frequency drive.

Wiring

Cables for the control signals and the brake cable must be shielded in order to comply with EMC specifications. The maximum cable length and the maximum cable cross section is listed in the Specification Chart.

Signal Wiring

VLT ® Series 2000

The Electronic Thermal Relay (ETR) in UL listed VLT's provides class 20 motor overload protection in accordance with NEC in single motor applications, when parameter 315 is set to to nominal motor (nameplate) current.

The correct sizes and ratings can be found in the Specification Chart.

Any motor cable shielding is connected to the ground terminals in the adjustable frequency drive and the motor. If non-shielded cables are used, the control inputs can occasionally be subject to signal disturbances. Normally such a disturbance will not affect the VLT.

All Danfoss VLT Series 2000 AC drives utilize the same control card throughout the entire HP range. The VL T control panel consists of a keyboard and a display.

The keyboard is used for two purposes: local control and programming. The display communicates VLT, motor and application information to the operator.

Located on the control panel is a red and green status LED. When the green status LED is illuminated, there is AC power applied to the VL T . The red LED is used for alarm indications. In an ALARM MODE, the LED will flash.

The display is a three-line LCD display. Line A is used for operating displays. It shows the value corresponding to the setting in DISPLAY MODE. The set value remains in the display line during programming of parameters. Line B shows information about parameters and direction of motor operation. Line C shows information about status and setup or data value.

107 Motor Current (MOTOR CURR)

Value:

MAG (par. 108)

Function:

It is important to specify the rated motor current because it is used in part to calculate torque and thermal motor protection, (ETR),

Description:

The rated motor current, which can be seen from the motor nameplate, must be entered. This is also chosen in Quick Set Up Menu step 2.

108 Motor Magnetizing Current (MOTOR MAG AMP)

Value:

0.3 - I

Function:

The VLT uses the value for different calculations such as compensation.

Description:

If the factory setting is unsuitable, the motor current on running idle should be measured with suitable amperemeter (RMS). The magnetizing current is then set to the measured value.

109 Start Voltage (START VOLT)

Value:

0 to (V

Function:

By increasing the start voltage, a high start torque can be obtained. Small motors (<1 HP) normally require a high start voltage. When motors are connected in parallel, it may be desirable to increase the starting torque.

Description:

Do not forget to consider that the motor must be able to start with the required torque:

1. Choose a value to make start possible with the load in question.

2. Reduce value until starting up with the given load is just possible.

3. Choose a value where operation in the rest of the frequency range is possible at the lowest possible current consumption.

If the start voltage makes normal operation impossible, you can change the V/f ratio in parameter 111.

112 Slip Compensation (SLIP COMP.)

Value:

0.0 - 20 Hz

Function:

Slip Compensation

voltage of the VLT adjustable frequency drive with an increasing load to compensate for the motor's increasing slip (loss). This achieves a load-independent speed.

Description:

Choose a value so that the speed remains constant when the load increases. If the value is too high the speed increases with the load. This may lead to unstable motor operation. When you use synchronous motors and motors connected in parallel, set slip compensation to 0 Hz. Slip compensation should be avoided in case of high dynamics.

114 Feedback Signal (FEEDBACK T)

Value:

Voltage (VOLTAGE) [0]

★ Current (CURRENT) [1]

Pulses (PULSES) [2]

Function:

This parameter allows a choice of process feedback signal in a closed loop system, as chosen in parameter 101. It has no effect if parameter 101 is set to OPEN LOOP. For further information, see the section on the PID controller.

Description of choice:

If a PID controller is used, one of the inputs on terminal 29 (parameter 405), terminal 53 (parameter 412) or terminal 60 (parameter 413) must be used for the feedback signal. The same type of signal cannot be the reference signal.

119 FF Factor (FEED FWD F)

Value:

0 to 500% ★ 100%

Function:

This parameter is used in connection with a PI controller. The FF factor makes a large or small part of the reference signal around the PID controller so that the PI controller only affects part of the control signal. Any change of the setpoint will affect the motor rpm directly. The FF factor gives high dynamics at changes of the setpoint and less overswing.

Description of choice:

You can choose the required % value in the interval f Choose a value above 100% if the setpoint variations are only minor.

121 Proportional Gain (PROPRT/L G)

Value:

Function:

The proportional gain sets the amplification factor of the error (the difference between the feedback signal and the setpoint).

Description of choice:

Quick regulation is obtained at a high amplification, but if the amplification is too high, the process may become unstable due to overshoot.

122 Integral Time (INTEGRAL T)

Value:

Function:

The integral time determines how long the PI controller takes to correct the fault. The integral time results in a delay of the signal, and therefore has a dampening effect that will improve stability.

Description of choice:

Quick regulation is obtained through a short integral time. However, if this time is set too short, the process will become unstable. If the integral time is set long, regulation becomes unnecessarily slow. inactive.

209 Current Limit (CURRENT LI)

Value:

0.3 to I

VLT,MAX

Function:

Use this parameter to set the maximum intermittent output current. If the current limit is exceeded, the output frequency is reduced until the current falls to below the current limit. The output frequency will not increase to the reference level until the current has fallen below the current limit.

Description of choice:

The value set at the factory corresponds to a load which is 160% (VLT 2030, 3Ø 208-240 V: 140%) of the rated output current. If the current limit is to be used as motor protection, the rated motor current must be programmed. Parameter 310 determines the length of time that the drive will run in current limit before an overcurrent fault. The load range between 100 and 160% can be programmed, but it is only intended for intermittent operation therefore the unit can only give an output of 160% (VLT 2030, 3Ø 208-240 V: 140%) for 60 seconds. The intermittent operating time will be extended as the load drops below 110%, and becomes unlimited at 100%.

Group 5 -- Serial Data Interface

Using the serial RS 232 port (terminals 71 and 72) you can read and set parameters of the VLT adjustable frequency drive and issue reference and control commands. The serial port can be used for point to point communication between the VLT and a PC. Communication takes place by means of a protocol specified by Danfoss, and using the echo function (parameter 500) you can connect several VLT adjustable frequency drives.

The data format consists of 10 bits:

One start bit (logical 0) Eight data bits One stop bit (logical 1)

Set the baud rate (rate of transmission) in parameter 501 and the address of each unit in parameter 500.

Protocol:

The communication protocol for the VLT Series 2000 consists of 22 ASCII characters make it possible to operate, set and read parameters, and to receive status feedback from the VLT adjustable frequency drive.

The communication takes place in the following way:

The master sends a telegram to a VLT adjustable frequency drive. Then the master awaits a reply from the VLT before sending a new message. The reply to the master resembles the telegram sent by the master, but now contains any updated data values and the status of the VLT.

Data format Telegram format

Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com

VLT® Series 2000 Programming

Byte 1:

Start byte, which in this case must be the character "<" (ASCII: 60).

Byte 2 and 3:

The two-digit address of the adjustable frequency drive. This address is also programmed in parameter 500. Sending to address 00 means transmission to all units connected to the bus. None of the units will reply, but they will carry out the command.

Byte 4:

Control parameter telling the drive what to do with the following data values.

U (update) Means that the data value, bytes (14-18), must be read into the drive.

R (read) Means that the master wishes to read the data value of the parameter in bytes 9 through 12.

C (control) Means that the drive reads only the four command bytes, 5 through 8, and returns with status. Parameter number and data value are ignored.

I (read index) Means that the drive reads the index and parameter and returns with status. The parameter is stated in bytes 9 through 12 and index is stated in bytes 13 through 18. Parameters with indices are read-only parameters. Action will be taken on the control word.

Byte 5 through 8:

Control and status words, used to send commands to the frequency converter and to send status from the frequency converter to the master.

Byte 9 through 12:

The parameter number is inserted in these bytes.

Byte 13:

Used for the sign before data value in bytes 14 through 18. All characters other than “-” are taken as “+”.

Byte 14 through 18:

Here is placed the data value of the parameter stated in bytes 9 through 12. The value must be a whole number. If a decimal point is needed, it is stated in byte 19.

NOTE:

Some data values have brackets with a number, for example “[0]”. Use this number instead of the “Text” data value.

Byte 19:

The position of the decimal point in the data value stated in bytes 14-18. The number states the number of characters after the decimal point. Consequently, byte 19 can be 0, 1, 2, 3, 4 or 5. For example, the number 23.75 is stated: Byte no. 13 14 15 16 17 18 19 in ASCII character + 23750 3 If byte 19 = 9, this indicates an unknown parameter.

Byte 20 and 21:

Used for summary control. If there is to be no control, the function can be cancelled by means of the “?” character (ASCII: 63) in the two bytes.

Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com

Byte 22:

Stop byte, stating the end of the telegram. The character “>” is used (ASCII: 62).

Programming VLT® Series 2000

VLT Status

The four control and status bytes are used to send control commands to the adjustable frequency drive when the telegram is sent from the master and to send status from the VLT to the master when the telegram is returned from the VLT adjustable frequency drive. The four bytes operate as status from the VLT with the following functions:

Appendix; PI Regulation

The following instructions will enable quick and easy setup of the PI regulation and associated parameter settings. Detailed information about each parameter can be found in the parameter section of this manual.

Parameter 100:

Set the load type. There are several choices in each group but variable torque medium or variable torque

medium with AEO will suit most pumps or fans.

Parameter 101: Select closed loop operation.

Parameter 114:

Choose the type of feedback signal the transmitter is using. The default value is current as it is the most widely used signal type.

Parameter 115 & 116:

Are used to scale a display read-out which is proportional to the feedback transmitter signal. The value is displayed only if feedback has been selected in display mode. To get to display mode from any other mode press MENU & DATA keys simultaneously. If a transmitter has a range of 0-5 bar, 0 can be set in parameter 115 and 5 in parameter 116. In parameter 117 the unit bar can be programmed. The default values are 0 & 100, to display 0-100%.

Parameter 117: Choose the unit of measurement for scaling the

feedback signal of the transmitter set in parameter 115 &

116. The default value is %.

Parameter 119:

The feed forward factor allows a part of the set-point signal to by-pass the PID regulator. This gives faster response when starting up a system where the integration time (parameter 122) is very long, and the system error is small. Set at 0%. Only add 5% at a time, and only if the system takes a long time to start up. The drawing shows the influence of the feed forward.

Parameter 120:

Controls the bandwidth of the output from PID controller.

Set at 100%.

Parameter 121:

Controls the gain of the system. For most fan and pump systems it should not be higher than 0.9. If set to higher values the system may become unstable.

• Centrifugal fans - between 0.1 - 0.6

• Centrifugal pumps - between 0.3 - 0.8

Parameter 122:

Improves the final accuracy by integrating out the error.

• Centrifugal fans - between 10-12 seconds

• Centrifugal pumps - between 3-8 seconds

Parameter 123:

Differential time is not used in pump and fan systems.

Set to Off.

Parameter 124:

If the feedback signal is fluctuating it can be dampened with a time constant. This can occur on pump systems where the pipe can be shut off quickly and cause a standing wave of water.

Set initially to 0 seconds.

Parameter 125: Leave at the default value of 100% unless the following conditions occur.

• If the feedback signal does not match the standard analog signal choices in parameter 412 & 413 a value must be programmed which scales the feedback signal to a standard analog value.

• When using min. speed, parameter 201, it must be ensured that the min. speed % value is not greater than the set-point % value, otherwise the min. speed will over-ride the set-point.

Process

Appendix; PI Regulation

Example:

The set-point is 40%, and the min. speed is 50%.

1. Selecting a new set-point. Choose a value that will raise the set-point about 10% higher than the min. speed. New set-point = % min. speed x 1.1 = 55%

2. Setting parameter 125. Apply the same increase to this parameter. 100 x 1.1 = 110%

Parameter 201:

Set min. frequency if required. If you enter a min. speed you must observe the following:

• When min. speed is used parameter 411 must be set to "proportional with min. limit".

• If the min. frequency % is higher than the set-point % you must re-scale parameter 125 and the set-point.

Parameter 202:

Max. frequency is normally set to 50 Hz. Running centrifugal pumps and fans above this speed will cause overload of the pump or fan, as the power increases to the third power of the speed change.

Example:

If the speed increased to 60 Hz the power will increase by a massive 173%.

Set at 50 Hz.

Parameter 205:

The internal set-point for the regulator.

Enter the set-point % value.

Example:

A pressure transmitter has range of 0-10 bar. A set-point of 4 bar is required. Set-point = 4/10 x 100 = 40% Enter 40 in parameter 205.

Parameter 214: Use only linear ramps.

Parameter 215 & 216:

The ramps only function on starting and stopping the system.

Enter the ramp up and down times in seconds.

Parameter 315:

Set the motor thermal protection to trip 1 if thermal protection of the motor is required.

Parameter 411:

This parameter must be changed from its default value when PID regulation is used.

Set to "proportional with min. limit".

Parameter 412-413: Set the type of analog input signal for the set-point and feedback signals. Parameter 114 has previously set

up the selection of the feedback signal type. If parameter 205 (internal set-point) is used either current or voltage can be used as the feedback signal.

If one of the inputs is not used it must be set to no operation.

Externally it can be one of the choices of the analog values. Use of one of the analog choices will prevent its use as the feedback signal. The use of the internal set-point reduces installation costs. Up to 4 internal set-points (by using parameters 205-208) can be selected by a combination of 2 switches. Refer to the instruction manual for further information. The set-point can be found by calculating the percentage of required signal from the transmitter range.

Normal or Inverse Control

Introduction:

The control is called normal, if the motor speed is increased when the feedback signal goes down, and the motor speed is reduced if the feedback signal goes up. Typical for pump pressure systems and air handling units in variable air volume systems. The control is called inverse if the motor speed is increased when the feedback signal is increased. Typical for pit pumping where: the faster the water flows into the pit, the faster the pump must pump out the water.

Appendix; PI Regulation

For inverse control; modification of the setpoint and feedback signal is required.

Example: A transmitter has a 0-15 foot span equal to 0-20mA. The PID set-point must be set at 12 feet for inverse control.

• Enter 20-0 mA in parameter 413. The normal signal in figure A is converted to an inverse signal as shown in figure B.

Figure B.

• Calculate the set point for inverse control.

Setpoint = 100 – (4/5 x 100) = 20% It can be seen in figure C how the set point is calculated.

• If the internal set-point is used, ensure that parameter 412 (voltage input) is set to no operation.

• The values in parameter 115 & 116 must be reversed.

The display at min. feedback in parameter 115 becomes display at max. feedback and parameter 116 becomes display at min. feedback.

• Connections and set-up are identical to normal control.

External Manual Control Over-ride

It is often necessary to run the machine manually for maintenance reasons. Manual control can be carried out manually from the keypad of all the units. If remote control of the manual over-ride is required additional circuitry is necessary. For the VLT Series 3500 special parameters are available for external manual over-ride. Refer to the VLT Series 3500 instruction manual.

The following circuit and instructions for external manual over-ride relates to the VLT Series 3000. The proposed control scheme is based on using 2 of the 4 menu setups. Menu set-up 1 has the parameters set for PI operation and Menu set-up 2 has the parameters set for manual control.

1. Set parameter 001 to multi set-up.

2. Set parameter 400 to select set-up.

3. Install an "Auto-Manual" switch across terminals 12 &

16. This will allow selection between the 2 menu setups. The bottom right hand corner of the display will show the menu set-up you are in.

• Parameter 315; Set the motor thermal overload protection to trip 2.

• Parameter 412; Set to 0-10 V.

• Parameter 413; Set to no operation.

5. Select menu set-up 2 and alter the following parameters:

• Parameter 100; Set to the same load type as in

menu 1. You can check the parameter data in menu 2 against the parameter data in menu 1 by switching between menu set-ups while you are in that parameter.

• Parameter 107-113; Set to the same load types as

in menu 1.

• Parameter 201-201; Max. and Min. Frequency can

be set to suit manual control.

• Parameter 209; Set to the same load type as in

menu 1.

• Parameter 215-216; Set the ramp times to suit the

application.
