Introduction

VLT® HVAC Basic Drive Programming Guide

Miscellaneous: Analog Inputs The analog inputs are used for controlling various functions of the Adjustable frequency drive. There are two types of analog inputs: Current input, 0-20 mA and 4-20 mA Voltage input, 0-10 V

Analog Outputs The analog outputs can supply a signal of 0–20 mA, 4–20 mA.

Automatic Motor Adaptation, AMA AMA algorithm determines the electrical parameters for the connected motor at standstill.

CTW Control Word

Digital Inputs The digital inputs can be used for controlling various functions of the Adjustable frequency drive.

ETR Electronic Thermal Relay is a thermal load calculation based on present load and time. Its purpose is to estimate the motor or Adjustable frequency drive temperature.

Initializing If initialization is carried out (14-22 Operation Mode), the Adjustable frequency drive returns to the default setting.

Intermittent Duty Cycle An intermittent duty rating refers to a sequence of duty cycles. Each cycle consists of an on-load and an off-load period. The operation can be either periodic duty or nonperiodic duty.

LCP The Local Control Panel makes up a complete interface for control and programming of the adjustable frequency drive. The control panel is detachable and can be installed up to 10 ft [3 m] from the adjustable frequency drive, i.e., in a front panel by means of the installation kit option.

lsb Least significant bit.

msb Most significant bit.

MCM Short for Mille Circular Mil, an American measuring unit for cable cross-sections. 1 MCM = 0.5067 mm2.

Process PI The PI control maintains the desired speed, pressure, temperature, etc. by adjusting the output frequency to match the varying load.

Power Cycle Switch off line power until the display (LCP) is dark – then turn power on again.

RCD Residual Current Device.

Set-up You can save parameter settings in two set-ups. Change between the two parameter set-ups and edit one set-up, while another set-up is active.

Slip Compensation The adjustable frequency drive compensates for the motor slip by giving the frequency a supplement that follows the measured motor load, keeping the motor speed almost constant. Slip compensation is default set to off.

Smart Logic Control (SLC) The SLC is a sequence of user-defined actions executed when the associated user-defined events are evaluated as true by the Smart Logic Controller. (Parameter group 13-** Smart Logic Control (SLC).)

STW Status Word

Adjustable Frequency Drive Standard Bus Includes RS-485 bus with FC protocol. See 8-30 Protocol.

Thermistor A temperature-dependent resistor placed where the temperature is to be monitored (adjustable frequency drive or motor).

Trip A state entered in fault situations, e.g., if the adjustable frequency drive is subject to an over-temperature or when the adjustable frequency drive is protecting the motor, process or mechanism. Restart is prevented until the cause of the fault has disappeared and the trip state is canceled by activating reset or, in some cases, by being programmed to reset automatically. Trip may not be used for personal safety.

Trip Lock A state entered in fault situations when the adjustable frequency drive is protecting itself and requiring physical intervention, e.g., if the adjustable frequency drive is subject to a short circuit on the output. A locked trip can only be canceled by cutting off line power, removing the cause of the fault, and reconnecting the adjustable frequency drive. Restart is prevented until the trip state is canceled by activating reset or, in some cases, by being programmed to reset automatically. Trip may not be used for personal safety.

VT Characteristics Variable torque characteristics used for pumps and fans.

In addition, a high power factor indicates that the different harmonic currents are low. The built-in DC coils in the adjustable frequency drive produce a high power factor, which minimizes the imposed load on the line power supply.

Safety Precautions

1.1.6

WARNING

The voltage of the adjustable frequency drive is dangerous whenever connected to line power. Incorrect installation of the motor, adjustable frequency drive or serial communication bus may cause death, serious personal injury or damage to the equipment. Consequently, the instructions in this manual, as well as national and local rules and safety regulations, must be complied with.

Safety Regulations

1. The line power supply to the adjustable frequency drive must be disconnected whenever repair work is to be carried out. Make sure that the line power supply has been disconnected and that the necessary time has elapsed before removing motor and line power supply plugs.

2. The [OFF] key on the control panel of the adjustable frequency drive does not disconnect the line power supply and consequently it must not be used as a safety switch.

3. The equipment must be properly grounded, the user must be protected against supply voltage

and the motor must be protected against overload in accordance with applicable national and local regulations.

4. The ground leakage current exceeds 3.5 mA.

5. Protection against motor overload is not included in the factory setting. If this function is desired, set 1-90 Motor Thermal Protection to data value [4] ETR trip 1 or data value [3] ETR warning 1.

6. Do not remove the plugs for the motor and line power supply while the adjustable frequency drive is connected to line power. Make sure that the line power supply has been disconnected and that the necessary time has elapsed before removing motor and line power plugs.

7. Please note that the adjustable frequency drive has more voltage sources than L1, L2 and L3, when load sharing (linking of DC intermediate circuit) or external 24 V DC are installed. Make sure that all voltage sources have been disconnected and that the necessary time has elapsed before commencing repair work.

Safety Precautions - Continued

1.1.7

Warning against unintended start

1. The motor can be brought to a stop by means of digital commands, bus commands, references or a local stop, while the adjustable frequency drive is connected to line power. If personal safety considerations (e.g., risk of personal injury caused by contact with moving machine parts following an unintentional start) make it necessary to ensure that no unintended start occurs, these stop functions are not sufficient. In such cases, the line power supply must be disconnected.

2. The motor may start while setting the parameters. If this means that personal safety may be compromised (e.g., personal injury caused by contact with moving machine parts), motor starting must be prevented, for instance by secure disconnection of the motor connection.

3. A motor that has been stopped with the line power supply connected, may start if faults occur in the electronics of the adjustable frequency drive, through temporary overload or if a fault in the power supply grid or motor connection is remedied. If unintended start must be prevented for personal safety reasons (e.g., risk of injury caused by contact with moving machine parts), the normal stop functions of the adjustable frequency drive are not sufficient.

Introduction

VLT® HVAC Basic Drive Programming Guide

4. Control signals from, or internally within, the adjustable frequency drive may in rare cases be activated in error, be delayed or fail to occur entirely. When used in situations where safety is critical, these control signals must not be relied on exclusively.

WARNING

High Voltage

Touching the electrical parts may be fatal - even after the equipment has been disconnected from line power. Also make sure that other voltage inputs have been disconnected, such as load sharing (linkage of DC intermediate circuit) Systems where adjustable frequency drives are installed must, if necessary, be equipped with additional monitoring and protective devices according to the valid safety regulations, e.g., law on mechanical tools, regulations for the prevention of accidents, etc. Modifications on the adjustable frequency drives by means of the operating software are allowed.

NOTE!

Hazardous situations shall be identified by the machine builder/integrator who is responsible for taking necessary preventive means into consideration. Additional monitoring and protective devices may be included, always according to valid national safety regulations, e.g., law on mechanical tools, regulations for the prevention of accidents.

Protection Mode Once a hardware limit on motor current or DC link voltage is exceeded, the adjustable frequency drive will enter Protection mode. Protection mode means a change of the PWM modulation strategy and a low switching frequency to minimize losses. This continues 10 sec after the last fault and increases the reliability and the robustness of the adjustable frequency drive while re-establishing full control of the motor. Parameter 0-07 Auto DC Braking may cause PWM when coasted.

3.1.2 0-1* Define and set-up Operations

Define and control the individual parameter set-ups. Userdefined parameters and miscellaneous external inputs (e.g., bus, LCP, analog/digital inputs, feedback, etc.) control the functionality of the adjustable frequency drive.

A complete set of all parameters controlling the adjustable frequency drive is called a set-up. The adjustable frequency drive contains 2 set-ups, Set-up 1 and Set-up 2. Furthermore, a fixed set of factory settings can be copied into one or more set-ups.

Some of the advantages of having more than one set-up in the adjustable frequency drive are:

Run motor in one set-up (Active Set-up) while

•

updating parameters in another set-up (Edit Setup)

Connect various motors (one at a time) to the

The Active Set-up can be set as Multi Set-up where the active set-up is selected via input on a digital input terminal and/or via the bus control word.

0-10 Active Set-up

Option: Function:

Select the set-up in which the adjustable frequency drive is to operate. Use 0-51 Set-up Copy to copy a set-up to one or all other set-ups. To avoid conflicting settings of the same parameter within two different set-ups, link the set-ups together using 0-12 Link Setups. Stop the adjustable frequency drive before switching between set-ups, where parameters marked ‘not changeable during operation’ have different values. Parameters which are ‘not changeable during operation’ are marked FALSE in the parameter lists in 5 Parameter Lists.

[1] Set-up 1 Set-up 1 is active.

[2] Set-up 2 Set-up 2 is active.

0-12 Link Setups

Option: Function:

The link ensures synchronizing of the “not changeable during operation” parameter values enabling shift from one set-up to another during operation.

If the set-ups are not linked, a change between them is not possible while the motor is running. Thus the set-up change does not occur until the motor is coasted.

[0] Not

3.5.5 Semi-Automatic Bypass Speed Set-up

The Semi-Automatic Bypass Speed Set-up can be used to facilitate the programming of the frequencies to be skipped due to resonances in the system.

The following process is to be carried out:

1. Stop the motor.

NOTE!

Smaller adjustable frequency drives have a ramp time of three seconds which can make it difficult to set the bypass speeds. Adjust the ramp times in 3-41 Ramp 1 Ramp Up Time and 3-42 Ramp 1 Ramp Down Time.

Select [1] Enabled in 4-64 Semi-Auto Bypass Set-up.

3. Press [Hand On] to start the search for frequency bands causing resonances. The motor will ramp up according to the ramp set.

NOTE!

Terminal 27 Digital Input 5-12 Terminal 27 Digital Input has coast inverse as default setting. This means that [Hand On] will not start the motor if there is no 24 V to terminal 27, so connect terminal 12 to terminal 27.

4. When sweeping through a resonance band, press [OK] on the LCP when leaving the band. The actual frequency will be stored as the first element in 4-63 Bypass Speed To [Hz] (array). Repeat this for each resonance band identified at the ramp-up (maximum three can be adjusted).

5. When maximum speed has been reached, the motor will automatically begin to ramp down. Repeat the above procedure when speed is leaving the resonance bands during the deceleration. The actual frequencies registered when pressing [OK] will be stored in 4-61 Bypass Speed From [Hz].

6. When the motor has ramped down to stop, press [OK]. The 4-64 Semi-Auto Bypass Set-up will automatically reset to Off. The adjustable frequency drive will stay in Hand On mode until [Off] or [Auto On] is pressed.

If the frequencies for a certain resonance band are not registered in the right order (frequency values stored in By Pass Speed To are higher than those in By Pass Speed From) or if they do not have the same numbers of registrations for the By Pass From and By Pass To, all registrations will be canceled and the following message is displayed: Collected

Description

function

[52] Run permissive The input terminal, for which the Run

permissive has been programmed must be logic “1” before a start command can be accepted. Run permissive has a logic ‘AND’ function related to the terminal which is programmed for [8] Start, [14] Jog or [20] Freeze Output, which means that in order to start running the motor, both conditions must be fulfilled. If Run permissive is programmed on multiple terminals, Run permissive needs only be logic ‘1’ on one of the terminals for the function to be carried out. The digital output signal for Run Request ([8] Start, [14] Jog or [20] Freeze Output) programmed in par. 5-3*, or par. 5-4*, will not be affected by Run Permissive.

NOTE!

If no Run permissive signal is applied but either Run, Jog or Freeze commands is activated, the status line in the display will show either Run Requested, Jog Requested or Freeze Requested.

[53] Hand Start A signal applied will put the adjustable

frequency drive into Hand mode as if [Hand On] has been pressed and a normal stop command will be overridden. If disconnecting the signal, the motor will stop. To make any other start commands valid, another digital input must be assigned to Auto-Start and a signal applied to this. The [Hand On] and [Auto On] keys have no impact. The [Off] key will override Hand Start and Auto Start. Press either the [Hand On] or [Auto On] key to make Hand Start and Auto Start active again. If no signal on either Hand Start or Auto-Start, the motor will stop regardless of any normal Start command applied. If signal applied to both Hand

Start and Auto-Start, the function will be Auto-Start.

[54] Auto start A signal applied will put the adjustable

frequency drive into Auto mode as if [Auto On] has been pressed. See also [53] Hand Start.

13-0* SLC Settings

3.9.1 13-** Prog. Features

Smart Logic Control (SLC) is essentially a sequence of userdefined actions (see 13-52 SL Controller Action [x]) executed by the SLC when the associated user-defined event (see 13-51 SL Controller Event [x]) is evaluated as TRUE by the SLC. Events and actions are each numbered and linked together in pairs. This means that when [0] event is fulfilled (attains the value TRUE), [0] action is executed. After this, the conditions of [1] event will be evaluated and if evaluated TRUE, [1] action will be executed and so on. Only one event will be evaluated at any time. If an event is evaluated as FALSE, nothing happens (in the SLC) during the current scan interval and no other events will be evaluated. This means that when the SLC starts, it evaluates [0] event (and only [0] event) each scan interval. Only when [0] event is evaluated TRUE, will the SLC execute [0] action and start evaluating [1] event. It is possible to program from 1 to 20 events and actions. When the last event/action have been executed, the sequence starts over again from [0] event /[0] action.

Figure 3.13 Example with three event/actions

Starting and stopping the SLC: Starting and stopping the SLC can be done by selecting [1] On or [0] Off in 13-00 SL Controller Mode. The SLC always starts in state 0 (where it evaluates [0] event). The SLC starts when the Start Event (defined in 13-01 Start Event) is evaluated as TRUE (provided that [1] On is selected in

13-00 SL Controller Mode). The SLC stops when the Stop Event (13-02 Stop Event) is TRUE. 13-03 Reset SLC resets all

SLC parameters and starts programming from scratch.

Use the SLC settings to activate, deactivate and reset the Smart Logic Control sequence. The logic functions and comparators are always running in the background, which opens for separate control of digital inputs and outputs.

3.15 Main Menu - Application Functions Group 22

3.15.1 22-4* Sleep Mode

The purpose of sleep mode is to allow FC 101 to stop itself in situations where the system is satisfied. This will save energy, and keeps system from being over-satisfied (too high pressure, water cooled too much in cooling towers, building pressurisation problems). This is also important for a reason that some applications cannot allow the FC 101 to adjust motor down to low speed. This might damage pumps, cause insufficient lubrication in gearboxes, and make fans unstable.

The sleep controller has two important functions - ability to go to sleep at the right time, and ability to come out of a sleep mode at the right time. The goal is to keep FC 101 in sleep mode as long as possible to avoid cycling the motor on and off frequently, and at the same time keep the controlled system variable in acceptable range.

The sequence when running sleep mode in Open-loop:

The motor speed is less than 22-47 Sleep Speed

[Hz] and the motor has been running longer than 22-40 Minimum Run Time.

FC101 ramps the motor speed down to1-82 Min Speed for Function at Stop [Hz].

FC101 activates 1-80 Function at Stop. The adjustable frequency drive is now in sleep mode.

FC101 compares the speed setpoint with 22-43 Wake-Up Speed [Hz] to detect a wake-up situation.

The speed setpoint is greater than 22-43 Wake-Up Speed [Hz] and the sleep condition has last for more than 22-41 Minimum Sleep Time. The adjustable frequency drive is now out of sleep mode.

6. Go back to speed open-loop control (ramp motor speed up to the speed setpoint).

The sequence when running sleep mode in Closed-loop:

If 20-81 PI Normal/ Inverse Control = [0] Normal. When an error between Reference and Feedback is greater than 22-44 Wake-Up Ref./FB Diff, the adjustable frequency drive will go to Boost status. If 22-45 Setpoint Boost is not set, the adjustable frequency drive will go into sleep mode.

After 22-46 Maximum Boost Time, drive ramps the motor speed down to 1-82 Min Speed for Function at Stop [Hz].

The adjustable frequency drive activates 1-80 Function at Stop. The adjustable frequency drive is now in Sleep mode.

4. When an error between Reference and Feedback

is greater than 22-44 Wake-Up Ref./FB Diff, and the condition last more than 22-41 Minimum Sleep Time, the adjustable frequency drive is out of sleep mode.

5. The adjustable frequency drive goes back to Close-loop control.

NOTE!

Sleep mode will not be active when Local Reference is active (set speed manually by means of navigation keys on the LCP). Does not work in Hand-mode. Auto set-up in open-loop must be carried out before setting input/output in closedloop.

22-40 Minimum Run Time

Range: Function:

the motor after a start command (digital input or bus) before entering sleep mode.

22-41 Minimum Sleep Time

CAUTION

Please note the adjustable frequency drive is only one component of the VLT HVAC Basic Drive system. Correct function of Fire Mode depends on the correct design and selection of system components. Ventilation systems working in life safety applications have to be approved by the local fire authorities. Non-interruption of the adjustable

frequency drive due to Fire Mode operation could cause over pressure and result in damage to VLT HVAC Basic Drive system and components, including dampers and air ducts. The adjustable frequency drive itself could be damaged and it may cause damage or fire. Danfoss accepts no responsibility for errors, malfunctions personal injury or any damage to the adjustable frequency drive itself or components herein, VLT HVAC Basic Drive systems and components herein or other property when the adjustable frequency drive has been programmed for Fire Mode. In no event shall Danfoss be liable to the end user or any other party for any direct or indirect, special or consequential damage or loss suffered by such party, which has occurred due to the adjustable frequency drive being programmed and operated in Fire Mode.

Background Fire Mode is for use in critical situations, where it is imperative for the motor to keep running, regardless of the adjustable frequency drive's normal protective

functions. These could be ventilation fans in tunnels or stairwells for instance, where continued operation of the fan facilitates safe evacuation of personnel in the event of a fire. Some selections of Fire Mode Function cause alarms and trip conditions to be disregarded, enabling the motor to run without interruption.

Activation Fire Mode is activated only via digital input terminals. See parameter group 5-1* Digital Inputs.

Messages in display When Fire Mode is activated, the display will show a status message “Fire Mode” and a warning “Fire Mode”. Once Fire Mode is again deactivated, the status messages will disappear and the warning will be replaced by the warning “Fire M Was Active”. This message can only be reset by power-cycling the adjustable frequency drive supply. If, while the adjustable frequency drive is active in Fire Mode, a warranty-affecting alarm (see 24-09 FM Alarm Handling) should occur, the display will show the warning “Fire M Limits Exceeded”. Digital and relay outputs can be configured for the status messages “Fire Mode Active” and the warning “Fire M Was Active”. See parameter group5-3* and parameter group 5-4*. “Fire M was Active” messages can also be accessed in the warning word via serial communication. (See relevant documentation).

If this mode is selected, the adjustable frequency drive will continue to run, ignoring most alarms, even if doing so it may result in damage of the adjustable frequency drive. Critical alarms are alarms which cannot be suppressed, but a restart attempt is possible (Infinity Automatic Reset).

In case of a critical alarm, the adjustable frequency drive will trip and not auto-restart (Manual Reset).

It is possible to test the operation of Fire Mode, but all alarm states are activated normally (Manual Reset).

NOTE!

Warranty-affecting alarms. Certain alarms can affect the lifetime of the adjustable frequency drive. If one of these disregarded alarms occurs while in Fire Mode, a log of the event is stored in the Fire Mode Log. This is where the 10 latest events caused by warrantyaffecting alarms, fire mode activation and fire mode deactivation are stored.

The adjustable frequency drive includes a feature which can be used to automatically activate an external electromechanical bypass in case of the event of a Fire Mode Coast (see 24-00 FM Function).

The bypass will switch the motor to operation direct on line. The external bypass is activated by means of one of the digital outputs or relays in the adjustable frequency drive, when programmed in parameter group 5-3* or parameter group 5-4*.

NOTE!

The drive bypass cannot be deactivated if in Fire Mode. It can be deactivated only by either removing the Fire Mode command signal or the power supply to the adjustable frequency drive!

When the Drive Bypass function is activated, the display on the LCP will show the status message Drive Bypass. This message has a higher priority than the Fire Mode status messages. When the automatic Drive Bypass function is enabled, it will cut in the external bypass according to the below sequence:

4.1.1 Alarms and Warnings

A warning or an alarm is signaled by the relevant LED on the front of the adjustable frequency drive and indicated by a code on the display.

A warning remains active until its cause is no longer present. Under certain circumstances operation of the motor may still be continued. Warning messages may be critical, but are not necessarily so.

In the event of an alarm, the adjustable frequency drive will have tripped. Alarms must be reset to restart operation once their cause has been rectified.

This may be done in four ways:

1. By pressing [Reset].

2. Via a digital input with the “Reset” function.

3. Via serial communication.

4. By resetting automatically using the [Auto Reset] function, which is a default setting for VLT HVAC Basic Drive, see 14-20 Reset Mode.

NOTE!

After a manual reset pressing [Reset], the [Auto On] or [Hand On] must be pressed to restart the motor.

If an alarm cannot be reset, the reason may be that its cause has not been rectified, or the alarm is trip-locked (see also table on following page).

4 4

CAUTION

Alarms that are trip-locked offer additional protection, means that the line power supply must be switched off before the alarm can be reset. After being switched back on, the adjustable frequency drive is no longer blocked and may be reset as described above, once the cause has been rectified. Alarms that are not trip-locked can also be reset using the automatic reset function in 14-20 Reset Mode (Warning: automatic wake-up is possible!) If a warning and alarm is marked against a code in the table on the following page, this means that either a warning occurs before an alarm, or it can be specified whether it is a warning or an alarm that is to be displayed for a given fault. This is possible, for instance, in 1-90 Motor Thermal Protection. After an alarm or trip, the motor carries on coasting, and the alarm and warning flash on the adjustable frequency drive. Once the problem has been rectified, only the alarm continues flashing.

(X) Dependent on parameter

A trip is the action when an alarm has appeared. The trip will coast the motor and can be reset by pressing the reset button or make a reset by a digital input (parameter group 5-1* [1]). The original event that caused an alarm cannot damage the adjustable frequency drive or cause dangerous conditions. A trip lock is an action that occurs in conjunction with an alarm, which may cause damage to the adjustable frequency drive or connected parts. A trip lock situation can only be reset by power cycling.
