3.2.3. 0-1* Set-up Operations
Define and control the individual parameter set-ups.
The frequency converter has four parameter setups that can be programmed independently of each other. This makes the frequency converter very
flexible and able to meet the requirements of many different VLT HVAC Drive system control schemes often saving the cost of external control equipment.
For example these can be used to program the frequency converter to operate according to one control scheme in one setup (e.g. daytime operation)
and another control scheme in another setup (e.g. night set back). Alternatively they can be used by an AHU or packaged unit OEM to identically program
all their factory fitted frequency converters for different equipment models within a range to have the same parameters and then during production/
commissioning simply select a specific setup depending on which model within that range the frequency converter is installed on.
The active setup (i.e. the setup in which the frequency converter is currently operating) can be selected in parameter 0-10 and is displayed in the LCP.
Using Multi set-up it is possible to switch between set-ups with the frequency converter running or stopped, via digital input or serial communication
commands (e.g. for night set back). If it is necessary to change setups whilst running, ensure parameter 0-12 is programmed as required. For the majority
of VLT HVAC Drive applications it will not be necessary to program parameter 0-12 even if change of set up whilst running is required, but for very
complex applications, using the full flexibility of the multiple setups, it may be required. Using parameter 0-11 it is possible to edit parameters within any
of the setups whilst continuing the frequency converter operation in its Active Setup which can be a different setup to that being edited. Using parameter
0-51 it is possible to copy parameter settings between the set-ups to enable quicker commissioning if similar parameter settings are required in different
set-ups.

0-12 This Set-up Linked to
Option:
Function:
This parameter only needs to be programmed if changing set-ups is required whilst the motor is running. It
ensures that parameters which are "not changeable during operation" have the same setting in all relevant setups.
To enable conflict-free changes from one set-up to another whilst the frequency converter is running, link setups containing parameters which are not changeable during operation. The link will ensure synchronising of the
‘not changeable during operation’ parameter values when moving from one set-up to another during operation.
‘Not changeable during operation’ parameters can be identified by the label FALSE in the parameter lists in the
section Parameter Lists.
The par. 0-12 link set-up feature is used when Multi set-up in par. 0-10 Active Set-up is selected. Multi set-up
can be used to move from one set-up to another during operation (i.e. while the motor is running).
Example:
Use Multi set-up to shift from Set-up 1 to Set-up 2 whilst the motor is running. Programme parameters in Setup 1 first, then ensure that Set-up 1 and Set-up 2 are synchronised (or ‘linked’). Synchronisation can be
performed in two ways:
1. Change the edit set-up to Set-up 2 [2] in par. 0-11 Edit Set-up and set par. 0-12 This Set-up Linked to to
Set-up 1 [1]. This will start the linking (synchronising) process.

Logged data and Preventive Maintenance.
It is possible to program the clock for Daylight Saving Time / summertime, weekly working days/non-working days including 20 exceptions (holidays
etc.). Although the clock settings can be set via the LCP, they can also be set along with timed actions and preventative maintenance functions using the
MCT10 software tool.
NB!
The frequency converter has no back up of the clock function and the set date/time will reset to default (2000-01-01 00:00) after a
power down unless a Real Time Clock module with back up is installed. If no module with back up is installed, it is recommended the
clock function is only used if the frequency converter is integrated into the BMS using serial communications, with the BMS maintaining
synchronization of control equipment clock times. In par. 0-79, Clock Fault, it is possible to program for a Warning in case clock has
not been set properly, e.g. after a power down.

limit.
If power monitoring is set to Off [0] or Warning [1], the brake function remains active, even if the monitoring limit is exceeded. This may lead to thermal
overload of the resistor. It is also possible to generate a warning via a relay/digital outputs. The measuring accuracy of the power monitoring depends
on the accuracy of the resistance of the resistor (better than ± 20%).
2-15 Brake Check
Option:
Function:
Select type of test and monitoring function to check the connection to the brake resistor, or whether a brake
resistor is present, and then display a warning or an alarm in the event of a fault. The brake resistor disconnection
function is tested during power-up. However the brake IGBT test is performed when there is no braking. A
warning or trip disconnects the brake function.
The testing sequence is as follows:
1.
The DC link ripple amplitude is measured for 300 ms without braking.
2.
The DC link ripple amplitude is measured for 300 ms with the brake turned on.
3.
If the DC link ripple amplitude while braking is lower than the DC link ripple amplitude before braking
+ 1 %. Brake check failed, return a warning or alarm.
4.
If the DC link ripple amplitude while braking is higher than the DC link ripple amplitude before braking
+ 1 %. Brake check OK.

Monitors brake resistor and brake IGBT for a short-circuit, and to run a test for brake resistor disconnection
during power-up
[2]
Trip
Monitors for a short-circuit or disconnection of the brake resistor, or a short-circuit of the brake IGBT. If a fault
occurs the frequency converter cuts out while displaying an alarm (trip locked).
[3]
Stop and Trip
Monitors for a short-circuit or disconnection of the brake resistor, or a short-circuit of the brake IGBT. If a fault
occurs the frequency converter ramps down to coast and then trips. A trip lock alarm is displayed.
NB!
NB!: Remove a warning arising in connection with Off [0] or Warning [1] by cycling the mains supply. The fault must be corrected first.
For Off [0] or Warning [1], the frequency converter keeps running even if a fault is located.

3
All = Terminals 18, 19, 27, 29, 32, X30/2, X30/3, X30/4. X30/ are the terminals on MCB 101.
Functions dedicated to only one digital input are stated in the associated parameter.
All digital inputs can be programmed to these functions:
[0]
No operation
No reaction to signals transmitted to terminal.
[1]
Reset
Resets frequency converter after a TRIP/ALARM. Not all alarms can be reset.
[2]
Coast inverse
Leaves motor in free mode. Logic ‘0’ => coasting stop.
(Default Digital input 27): Coasting stop, inverted input (NC).
[3]
Coast and reset inverse Reset and coasting stop Inverted input (NC).
[5]
DC-brake inverse
Leaves motor in free mode and resets the frequency converter. Logic ‘0’ => coasting stop and reset.
Inverted input for DC braking (NC).
Stops motor by energizing it with a DC current for a certain time period. See par. 2-01 to par. 2-03. The function
is only active when the value in par. 2-02 is different from 0. Logic ’0’ => DC braking.
[6]
Stop inverse
Stop Inverted function. Generates a stop function when the selected terminal goes from logical level ‘1’ to ‘0’.
The stop is performed according to the selected ramp time (par. 3-42, par. 3-52, par. 3-62, par. 3-72).
NB!
When the frequency converter is at the torque limit and has received a stop command, it may
not stop by itself. To ensure that the frequency converter stops, configure a digital output to
Torque limit & stop [27] and connect this digital output to a digital input that is configured
as coast.
[7]
External Interlock
Same function as Coasting stop, inverse, but External Interlock generates the alarm message ’external fault’ on
the display when the terminal which is programmed for Coast Inverse is logic ‘0’. The alarm message will also
be active via digital outputs and relay outputs, if programmed for External Interlock. The alarm can be reset
using a digital input or the [RESET] key if the cause for the External Interlock has been removed. A delay can
be programmed in par. 22-00, External Interlock Time. After applying a signal to the input, the reaction described
above will be delayed with the time set in par. 22-00.
[8]
Start
Select start for a start/stop command. Logic ‘1’ = start, logic ‘0’ = stop.
(Default Digital input 18)
[9]
Latched start
Motor starts, if a pulse is applied for min. 2 ms. Motor stops when Stop inverse is activated
[10]
Reversing
Changes direction of motor shaft rotation. Select Logic ‘1’ to reverse. The reversing signal only changes the
direction of rotation. It does not activate the start function. Select both directions in par. 4-10 Motor Speed
Direction.
(Default Digital input 19).
[11]
Start reversing
[14]
Jog
Used for start/stop and for reversing on the same wire. Signals on start are not allowed at the same time.
Used for activating jog speed. See par. 3-11.
(Default Digital input 29)
[15]
Preset reference on
Used for shifting between external reference and preset reference. It is assumed that External/preset [1] has
been selected in par. 3-04. Logic '0' = external reference active; logic '1' = one of the eight preset references
is active.
[16]
Preset ref bit 0
Enables a choice between one of the eight preset references according to the table below.
[17]
Preset ref bit 1
Enables a choice between one of the eight preset references according to the table below.
[18]
Preset ref bit 2
Enables a choice between one of the eight preset references according to the table below.

Freezes actual reference. The frozen reference is now the point of enable/condition for Speed up and Speed
down to be used. If Speed up/down is used, the speed change always follows ramp 2 (par. 3-51 and 3-52) in
the range 0 - par. 3-03 Maximum Reference.
[20]
Freeze output
Freezes actual motor frequency (Hz). The frozen motor frequency is now the point of enable/condition for Speed
up and Speed down to be used. If Speed up/down is used, the speed change always follows ramp 2 (par. 3-51
and 3-52) in the range 0 - par. 1-23 Motor Frequency.
NB!
When Freeze output is active, the frequency converter cannot be stopped via a low ‘start [13]’
signal. Stop the frequency converter via a terminal programmed for Coasting inverse [2] or
Coast and reset, inverse [3].
[21]
Speed up
For digital control of the up/down speed is desired (motor potentiometer). Activate this function by selecting
either Freeze reference or Freeze output. When Speed up is activated for less than 400 msec. the resulting
reference will be increased by 0.1 %. If Speed up is activated for more than 400 msec. the resulting reference
will ramp according to Ramp 1in par. 3-41.
[22]
Speed down
Same as Speed up [21].
[23]

(Default Digital input 32)
[32]
Pulse input
Select Pulse input when using a pulse sequence as either reference or feedback. Scaling is done in par. group
5-5*.
[34]
Ramp bit 0
Select which ramp to use. Logic “0” will select ramp 1 while logic “1” will select ramp 2.
[36]
Mains failure inverse
Select to activate function selected in par. 14-10 Mains failure. Mains failure is active in the Logic “0” situation.
[37]
Fire mode
A signal applied will put the frequency converter into Fire Mode and all other commands will be disregarded.
See 24-0* Fire Mode.
[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 START [8], Jog [14] or Freeze Output [20], 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
(Start [8], Jog [14] or Freeze output [20]) programmed in par. 5-3* Digital outputs, or par. 5-4* Relays, will
not be affected by Run Permissive.
[53]
Hand start
A signal applied will put the frequency converter into Hand mode as if button Hand On on the LCP 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 assign to Auto Start and a signal applied
to this. The Hand On and Auto On buttons on the LCP has no impact. The Off button on the LCP will override
Hand Start and Auto Start. Press either the Hand On or Auto On button to make Hand Start and Auto Start active
again. If no signal on neither Hand Start nor 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. If pressing
the Off button on the LCP the motor will stop regardless of signals on Hand Start and Auto Start.
[54]
Auto start
A signal applied will put the frequency converter into Auto mode as if the LCP button Auto On has been pressed.

DigiPot Increase
Uses the input as an INCREASE signal to the Digital Potentiometer function described in parameter group 3-9*
[56]
DigiPot Decrease
Uses the input as a DECREASE signal to the Digital Potentiometer function described in parameter group 3-9*
[57]

3. Parameter Description
3.13. Main Menu - Smart Logic - Group 13
3.13.1. 13-** Prog. Features
Smart Logic Control (SLC) is essentially a sequence of user defined actions (see par. 13-52 [x]) executed by the SLC when the associated user defined
event (see par. 13-51 [x]) is evaluated as TRUE by the SLC. Events and actions are each numbered and linked together in pairs. This means that when
event [0] is fulfilled (attains the value TRUE), action [0] is executed. After this, the conditions of event [1] will be evaluated and if evaluated TRUE,
action [1] 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 event [0] (and only event [0])
each scan interval. Only when event [0] is evaluated TRUE, will the SLC execute action [0] and start evaluating event [1]. It is possible to programme
from 1 to 20 events and actions.
When the last event / action has been executed, the sequence starts over again from event [0] / action [0]. The illustration shows an example with three
event / actions:
Starting and stopping the SLC:
Starting and stopping the SLC can be done by selecting On [1] or Off [0] in par. 13-00. The SLC always starts in state 0 (where it evaluates event [0]).
The SLC starts when the Start Event (defined in par. 13-01 Start Event) is evaluated as TRUE (provided that On [1] is selected in par. 13-00). The SLC
stops when the Stop Event (par. 13-02) is TRUE. Par. 13-03 resets all SLC parameters and start programming from scratch.
3.13.2. 13-0* SLC Settings
Use the SLC settings to activate, deactivate and reset the Smart Logic Control.

Enter the ‘trigger level’ for the variable that is monitored by this comparator. This is an array parameter containing
comparator values 0 to 5.
3.13.4. 13-2* Timers
This parameter group consists of timer parameters.
Use the result (TRUE or FALSE) from timers directly to define an event (see par. 13-51), or as boolean input in a logic rule (see par. 13-40, 13-42 or
13-44). A timer is only FALSE when started by an action (i.e. Start timer 1 [29]) until the timer value entered in this parameter is elapsed. Then it becomes
TRUE again.
All parameters in this parameter group are array parameters with index 0 to 2. Select index 0 to program Timer 0, select index 1 to program Timer 1,
and so on.
13-20 SL Controller Timer
Array [3]
0.00 s* [0.00 - 360000.00 s]
Enter the value to define the duration of the FALSE output from the programmed timer. A timer is only FALSE if
it is started by an action (i.e. Start timer 1 [29]) and until the given timer value has elapsed.
3.13.5. 13-4* Logic Rules
Combine up to three boolean inputs (TRUE / FALSE inputs) from timers, comparators, digital inputs, status bits and events using the logical operators
AND, OR, and NOT. Select boolean inputs for the calculation in par. 13-40, 13-42, and 13-44. Define the operators used to logically combine the selected
inputs in par. 13-41 and 13-43.
Priority of calculation
The results of par. 13-40, 13-41, and 13-42 are calculated first. The outcome (TRUE / FALSE) of this calculation is combined with the settings of par.
13-43 and 13-44, yielding the final result (TRUE / FALSE) of the logic rule.

3.14.5. Current Limit Control, 14-3*
The frequency converter features an integral Current Limit Controller which is activated when the motor current, and thus the torque, is higher than the
torque limits set in par. 4-16 and 4-17.
When the current limit is reached during motor operation or regenerative operation, the frequency converter will try to reduce torque below the preset
torque limits as quickly as possible without losing control of the motor.
While the current control is active, the frequency converter can only be stopped by setting a digital input to Coast inverse [2] or Coast and reset inv. [3].
Any signal on terminals 18 to 33 will not be active until the frequency converter is no longer near the current limit.
By using a digital input set to Coast inverse [2] or Coast and reset inv. [3], the motor does not use the ramp-down time, since the frequency converter
is coasted.
14-30 Current Lim Cont, Proportional Gain
Range:
Function:

3. Parameter Description
14-60 Function at Overtemperature
Option:
Function:
If either heatsink or control card temperature exceeds a factory-programmed temperature limit, a warning will
be activated. If the temperature increases further, select whether the frequency converter should trip (trip
locked) or derate the output current.
[0]
*
Trip
The frequency converter will trip (trip locked) and generate an alarm. Power must be cycled to reset the alarm,
but will not allow restart of the motor until the heat sink temperature has dropped below the alarm limit.
[1]
Derate
If the critical temperature is exceeded the output current will be reduced until the allowable temperature has
been reached.
3.14.9. No Trip at Inverter Overload
In some pump systems, the frequency converter has not been sized properly to yield the current needed in all points of the operational flow-head
characteristic. At these points, the pump will need a current higher than the rated current of the frequency converter. The frequency converter can yield
110% of the rated current continuously for 60 sec. If still overloaded, the frequency converter will normally trip (causing the pump to stop by coasting)
and provide an alarm.
It may be preferable to run the pump at reduced speed for a while in case it is not possible to run continuously with demanded capacity.
Select Function at Inverter Overload, par 14-61 to automatically reduce pump speed until the output current is below 100% of the rated current (set in
Derate Level, par. 14-62).
The Function at Inverter Overload is an alternative to letting the frequency converter trip.
The frequency converter estimates the load on the power section by means of an inverter load counter, which will cause a warning at 98% and a reset
of the warning at 90%. At the value 100%, the frequency converter trips and provides an alarm.
Status for the counter can be read in par. 16-35, Inverter Thermal.
If par. 14-61, Function at Inverter Overload, is set to Derate, the pump speed will be reduced when the counter exceeds 98, and stay reduced until the
counter has dropped below 90.7.
If par. 14-62, Derate Level, is set e.g. to 95% a steady overload will cause the pump speed to fluctuate between values corresponding to 110% and 95%
of rated output current for the frequency converter.

[5]
Multi setpoint min
Multi-setpoint minimum [5] sets up the PID Controller to calculate the difference between Feedback 1 and
Setpoint 1, Feedback 2 and Setpoint 2, and Feedback 3 and Setpoint 3. It will use the feedback/setpoint pair in
which the feedback is the farthest below its corresponding setpoint reference. If all feedback signals are above
their corresponding setpoints, the PID Controller will use the feedback/setpoint pair in which the difference
between the feedback and setpoint is the least.
NB!
If only two feedback signals are used, the feedback that is not to be used must be set to No
Function in par. 20-00, par. 20-03 or par. 20-06. Note that each setpoint reference will be the
sum of its respective parameter value (par. 20-11, par. 20-12 and par. 20-13) and any other
references that are enabled (see par. group 3-1*).
[6]
Multi setpoint max
Multi-setpoint maximum [6] sets up the PID Controller to calculate the difference between Feedback 1 and
Setpoint 1, Feedback 2 and Setpoint 2, and Feedback 3 and Setpoint 3. It will use the feedback/setpoint pair in
which the feedback is farthest above its corresponding setpoint reference. If all feedback signals are below their
corresponding setpoints, the PID Controller will use the feedback/setpoint pair in which the difference between
the feedback and the setpoint reference is the least.
NB!
If only two feedback signals are used, the feedback that is not to be used must be set to No
Function in par. 20-00, par. 20-03 or par. 20-06. Note that each setpoint reference will be the
sum of its respective parameter value (par. 20-21, par. 20-22 and par. 20-23) and any other
references that are enabled (see par. group 3-1*).
NB!
Any unused feedback must be set to “No function” in its Feedback Source parameter: 20-00, 20-03 or 20-06.
The feedback resulting from the function selected in par. 20-20 will be used by the PID Controller to control the output frequency of the frequency
converter. This feedback can also be shown on the frequency converter’s display, be used to control a frequency converter's analog output, and be
transmitted over various serial communication protocols.
The frequency converter can be configured to handle multi zone applications. Two different multi zone applications are supported:
•
Multi zone, single setpoint
•
Multi zone, multi setpoint
The difference between the two is illustrated by the following examples:
158
MG.11.C5.02 - VLT® is a registered Danfoss trademark
VLT® HVAC Drive Programming Guide
3. Parameter Description
Example 1 – Multi zone, single setpoint
In an office building, a VAV (variable air volume) VLT HVAC Drive system must ensure a minimum pressure at selected VAV boxes. Due to the varying
pressure losses in each duct, the pressure at each VAV box cannot be assumed to be the same. The minimum pressure required is the same for all VAV
boxes. This control method can be set up by setting Feedback Function, par. 20-20 to option [3], Minimum, and entering the desired pressure in par.
20-21. The PID Controller will increase the speed of the fan if any one feedback is below the setpoint and decrease the speed of the fan if all feedbacks
are above the setpoint.
3
Example 2 – Multi zone, multi setpoint
The previous example can be used to illustrate the use of multi zone, multi setpoint control. If the zones require different pressures for each VAV box,
each setpoint may be specified in par. 20-21, par. 20-22 and par. 20-23. By selecting Multi setpoint minimum, [5], in par. 20-20, Feedback Function, the
PID Controller will increase the speed of the fan if any one of the feedbacks is below its setpoint and decrease the speed of the fan if all feedbacks are
above their individual setpoints.

3.18.4. 20-3* Feedback Adv. Conversion
3
In air conditioning compressor applications it is often useful to control the system based on the temperature of the refrigerant. However, it is generally
more convenient to directly measure its pressure. This parameter group allows the frequency converter’s PID Controller to convert refrigerant pressure
measurements into temperature values.
20-30 Refrigerant
Option:
Function:
Select the refrigerant used in the compressor application. This parameter must be specified correctly for the
pressure to temperature conversion to be accurate. If the refrigerant used is not listed in choices [0] through
[6], select User defined [7]. Then, use par. 20-31, 20-32 and 20-33 to provide A1, A2 and A3 for the equation

Use this parameter to enter the value of coefficient A3 when par. 20-30 is set to User defined [7].
3.18.5. 20-7* PID autotuning
The frequency converter PID Closed Loop controller (parameters 20-**, FC Closed Loop) can be auto-tuned, simplifying and saving time during commissioning, whilst ensuring accurate PID control adjustment. To use autotuning it is necessary for the frequency converter to be configured for Closed
loop in par 1-00 Configuration Mode.
A Graphical Local Control Panel (LCP) must be used in order to react on messages during the autotuning sequence.
Enabling autotuning par 20-79, puts the frequency converter into autotuning mode. The LCP then directs the user with on-screen instructions.

3. Parameter Description
The fan/pump is started by pressing [Auto On] button on the LCP and applying a start signal. The speed is adjusted manually by pressing the [▲] or
[▼] navigation keys on the LCP to a level where the feedback is around the system setpoint.
NB!
It is not possible to run the motor at maximum or minimum speed, when manually adjusting the motor speed due to the need of giving
the motor a step in the speed during autotuning.
PID autotuning functions by introducing step changes whilst operating at a steady state and then monitoring the feedback. From the feedback response,
the required values for par 20-93 PID Proportional Gain and par 20-94 Integral Time are calculated. Par 20-95 PID Differentiation Time is set to value 0
(zero). Par. 20-81 PID Normal / Inverse Control is determined during tuning process.
These calculated values are presented on the LCP and the user can decide whether to accept or reject them. Once accepted, the values are written to
the relevant parameters and autotuning mode is disabled in par 20-79. Depending on the system being controlled the time required to carry out autotuning
could be several minutes.
It is advised to set the ramp times in par. 3-41/3-42 or par. 3-51/3-52 according to the load inertia before carrying out PID autotuning. If PID autotuning
is carried out with slow ramp times, the auto-tuned parameters will typically result in very slow control. Excessive feedback sensor noise should be
removed using the input filter (parameter groups 6-*, 5-5* and 26-*, Terminal 53/54 Filter Time Constant/Pulse Filter Time Constant #29/33) before
activating PID autotuning. In order to obtain the most accurate controller parameters, it is advised to carry out PID autotuning, when the application is
running in typical operation, i.e. with a typical load.
20-70 Closed Loop Type
Option:
Function:
This parameter defines the application response. The default mode should be sufficient for most applications.
If the application response speed is known, it can be selected here. This will decrease the time needed for
carrying out PID autotuning. The setting has no impact on the value of the tuned parameters and is used only
for the autotuning sequence.

20-72 PID Output Change
Range:
Function:
0.10* [0.01 - 0.50]
This parameter sets the magnitude of step change during autotuning. The value is a percentage of full speed.
I.e. if maximum output frequency in par 4-13/4-14, Motor Speed High Limit is set to 50Hz, 0.10 is 10% of 50Hz,
which is 5Hz. This parameter should be set to a value resulting in feedback changes of between 10% and 20%
for best tuning accuracy.

3.18.6. 20-8* Basic Settings
This parameter group is used to configure the basic operation of the frequency converter’s PID Controller, including how it responds to a feedback that
is above or below the setpoint, the speed at which it first starts functioning, and when it will indicate that the system has reached the setpoint.
20-81 PID Normal/Inverse Control
Option:
[0]
*
Function:
Normal
Normal [0] causes the frequency converter’s output frequency to decrease when the feedback is greater than
the setpoint reference. This is common for pressure-controlled supply fan and pump applications.
[1]
Inverse
Inverse [1] causes the frequency converter’s output frequency to increase when the feedback is greater than
the setpoint reference. This is common for temperature-controlled cooling applications, such as cooling towers.
20-82 PID Start Speed [RPM]
Range:
Function:
0* [0 - 6000 RPM]
When the frequency converter is first started, it initially ramps up to this output speed in Open Loop Mode,
following the active Ramp Up Time. When the output speed programmed here is reached, the frequency converter will automatically switch to Closed Loop Mode and the PID Controller will begin to function. This is useful
in applications in which the driven load must first quickly accelerate to a minimum speed when it is started.
NB!
This parameter will only be visible if par. 0-02 is set to [0], RPM.
20-83 PID Start Speed [Hz]
Range:
Function:
0 Hz* [0 - par. 4-14 Hz]
When the frequency converter is first started, it initially ramps up to this output frequency in Open Loop Mode,
following the active Ramp Up Time. When the output frequency programmed here is reached, the frequency
converter will automatically switch to Closed Loop Mode and the PID Controller will begin to function. This is
useful in applications in which the driven load must first quickly accelerate to a minimum speed when it is started.
NB!
This parameter will only be visible if par. 0-02 is set to [1], Hz.

3. Parameter Description
20-84 On Reference Bandwidth
Range:
Function:
5%* [0 - 200%]
When the difference between the feedback and the setpoint reference is less than the value of this parameter,
the frequency converter’s display will show “Run on Reference”. This status can be communicated externally by
programming the function of a digital output for Run on Reference/No Warning [8]. In addition, for serial communications, the On Reference status bit of the frequency converter’s Status Word will be high (1).
The On Reference Bandwidth is calculated as a percentage of the setpoint reference.

3.18.7. 20-9* PID Controller
This group provides the ability to manually adjust this PID Controller. By adjusting the PID Controller parameters the control performance may be
improved. See section PID in the VLT HVAC Drive Design Guide, MG.11.Bx.yy for guidelines on adjusting the PID Controller parameters.
20-91 PID Anti Windup
Option:
[0]
Function:
Off
Off [0] causes the PID Controller to continue to integrate (add) the error between the feedback and setpoint
reference even though the frequency converter cannot adjust its output frequency to correct this error. In this
case, the integral term of the PID Controller may become quite large. When the PID Controller can again control
the frequency converter’s output frequency, it may attempt to initially make a large change in the frequency
converter’s output frequency. This should generally be avoided.
[1]
*
On
On [1] stops the PID Controller from integrating (adding) the error between the feedback and the setpoint
reference if it is not possible to adjust the output frequency of the frequency converter to correct the error. This
can occur when the frequency converter has reached its minimum or maximum output frequency or when the
frequency converter is stopped.
20-93 PID Proportional Gain
Range:
Function:
0.50* [0.00 = Off - 10.00]
This parameter adjusts the output of the frequency converter’s PID Controller based on the error between the
feedback and the setpoint reference. Quick PID Controller response is obtained when this value is large. However,
if too large a value is used, the frequency converter’s output frequency may become unstable.
20-94 PID Integral Time
Range:
Function:
20.00 s* [0.01 - 10000.00 = Off s]
The integrator adds over time (integrates) the error between the feedback and the setpoint reference. This is
required to ensure that the error approaches zero. Quick frequency converter speed adjustment is obtained when
this value is small. However, if too small of a value is used, the frequency converter’s output frequency may
become unstable.
20-95 PID Differentiation Time
Range:
0.0 s* [0.00 = Off - 10.00 s]
Function:
The differentiator monitors the rate of change of the feedback. If the feedback is changing quickly, it will adjust
the output of the PID Controller to reduce the rate of change of the feedback. Quick PID Controller response is
obtained when this value is large. However, if too large of a value is used, the frequency converter’s output
frequency may become unstable.
Differentiation time is useful is situations where extremely fast frequency converter response and precise speed
control are required. It can be difficult to adjust this for proper system control. Differentiation time is not commonly used in VLT HVAC Drive applications. Therefore, it is generally best to leave this parameter at 0 or OFF.

3. Parameter Description
20-96 PID Diff. Gain Limit
Range:
Function:
5.0* [1.0 - 50.0]
The differentiator of a PID Controller responds to the rate of change of the feedback. As a result, an abrupt
change in the feedback can cause the differentiator to make a very large change in the PID Controller’s output.
This parameter limits the maximum effect that the PID Controller’s differentiator can produce. A smaller value
reduces the maximum effect of the PID Controller’s differentiator.
This parameter is only active when par. 20-95 is not set to OFF (0 s).

3.19. Main Menu - Extended Closed Loop - FC 100 - Group 21
3.19.1. 21-** Ext. Closed Loop
The FC102 offers 3 Extended Closed Loop PID controllers in addition to the PID Controller. These can be configured independently to control either
external actuators (valves, dampers etc.) or be used together with the internal PID Controller to improve the dynamic responses to setpoint changes or
load disturbances.
3
The Extended Closed Loop PID controllers may be interconnected or connected to the PID Closed Loop controller to form a dual loop configuration.
In order to control a modulating device (e.g. a valve motor), this device must be a positioning servo motor with built-in electronics accepting either a
0-10V (signal from Analog I/O card MCB 109) or a 0/4-20 mA (signal from Control Card and/or General Purpose I/O card MCB 101) control signal.
The output function can be programmed in the following parameters:
•
Control Card, terminal 42: Par. 6-50 (setting [113]...[115] or [149]...[151], Ext. Closed Loop 1/2/3

General Purpose I/O card and Analog I/O card are optional cards.
3.19.2. 21-0* Extended CL autotuning
The extended PID Closed Loop PID controllers (par 21-**, Ext. Closed Loop) can each be auto-tuned, simplifying and saving time during commissioning,
whilst ensuring accurate PID control adjustment.
To use PID autotuning it is necessary for the relevant Extended PID controller to have been configured for the application.
A Graphical Local Control Panel (LCP) must be used in order to react on messages during the autotuning sequence.
Enabling autotuning par 21-09 puts the relevant PID controller into PID autotuning mode. The LCP then directs the user with on-screen instructions.
PID autotuning functions by introducing step changes and then monitoring the feedback. From the feedback response, the required values for PID
Proportional Gain, par 21-21 for EXT CL 1, par 21-41 for EXT CL 2 and par 21-61 for EXT CL 3 and Integral Time, par 21-22 for EXT CL 1, par 21-42 for
EXT CL 2 and par 21-62 for EXT CL 3 are calculated. PID Differentiation Time, Par 21-23 for EXT CL 1, par 21-43 for EXT CL 2 and par 21-63 for EXT CL
3 are set to value 0 (zero). Normal / Inverse, par 21-20 for EXT CL 1, par 21-40 for EXT CL 2 and par 21-60 for EXT CL 3 are determined during the
tuning process.
These calculated values are presented on the LCP and the user can decide whether to accept or reject them. Once accepted, the values are written to
the relevant parameters and PID autotuning mode is disabled in par 21-09. Depending on the system being controlled the time required to carry out PID
autotuning could be several minutes.
Excessive feedback sensor noise should be removed using the input filter (parameter groups 6*,5.5* and 26*, Terminal 53/54 Filter Time Constant/Pulse
Filter Time Constant #29/33) before activating PID autotuning.

Function:
0.10* [0.01 - 0.50]
This parameter sets the magnitude of step change during autotuning. The value is a percentage of full operating
range. I.e. if maximum analog output voltage is set to 10 V, 0.10 is 10% of 10 V, which is 1 V. This parameter

3. Parameter Description

No Flow Detection is based on the measurement of speed and power. For a certain speed the frequency converter calculates the power at no flow.
This coherence is based on the adjustment of two sets of speed and associated power at no flow. By monitoring the power it is possible to detect no flow
conditions in systems with fluctuating suction pressure or if the pump has a flat characteristic towards low speed.
The two sets of data must be based on measurement of power at approx. 50% and 85% of maximum speed with the valve(s) closed. The data are
programmed in the par. 22-3*. It is also possible to run a Low Power Auto Set Up (par. 22-20), automatically stepping through the commissioning process
and also automatically storing the data measured. The frequency converter must be set for Open Loop in par. 1-00, Configuration Mode, when carrying
out the Auto Set Up (See No Flow Tuning par. 22-3*).
If to use the integrated PI controller, carry out No Flow tuning before setting the PI controller parameters!
Low speed detection:
Low Speed Detection gives a signal if the motor is operating with minimum speed as set in par. 4-11 or 4-12, Motor Low Limit. Actions are common with
No Flow Detection (individual selection not possible).
The use of Low Speed Detection is not limited to systems with a no flow situation, but can be used in any system where operation at minimum speed
allows for a stop of the motor until the load calls for a speed higher than minimum speed, e.g. systems with fans and compressors.
In pump systems ensure that the minimum speed in par. 4-11 or 4-12 has been set high enough for detection as the pump can run
with a rather high speed even with valves closed.
Dry pump detection:
No Flow Detection can also be used for detecting if the pump has run dry (low power consumption-high speed). Can be used with both the integrated
PI controller and an external PI controller.
The condition for Dry Pump signal:
-
Power consumption below no flow level
and
-
Pump running at maximum speed or maximum reference open loop, whichever is lowest.
The signal must be active for a set time (Dry Pump Delay par. 22-27) before selected the action takes place.
Possible Actions to select (par. 22-26):
-
Warning
-
Alarm
No Flow Detection must be enabled (par. 22-23, No Flow Function) and commissioned (par. 22-3*, No Power Tuning).

3. Parameter Description
3.20.3. 22-4* Sleep Mode
If the load on the system allows for stop of the motor and the load is monitored, the motor can be stopped by activating the Sleep Mode function. This
is not a normal Stop command, but ramps the motor down to 0 RPM and stops energizing the motor. When in Sleep Mode certain conditions are monitored
to find out when load has been applied to the system again.
Sleep Mode can be activated either from the No Flow Detection/Minimum Speed Detection ( must be programmed via parameters for No-Flow Detection,
3
see the signal flow-diagram in parameter group 22-2*, No-Flow Detection) or via an external signal applied to one of the digital inputs (must be programmed via the parameters for configuration of the digital inputs, par.5-1* selecting Sleep Mode).
To make it possible to use e.g. an electro-mechanical flow switch to detect a no flow condition and activate Sleep Mode, the action takes place at raising
edge of the external signal applied (otherwise the frequency converter would never come out of Sleep Mode again as the signal would be steady connected).
NB!
If Sleep Mode is to be based on No Flow Detection/Minimum Speed, remember to choose Sleep Mode [1] in par. 22-23, No Flow
Function.
If par. 25-26, Destage at No-Flow, is set for Enabled (see separate VLT HVAC Drive Programming Guide, MG.11.Cx.yy), activating Sleep Mode will apply
a command to the cascade controller (if enabled) to start destaging of lag pumps (fixed speed) before stopping the lead pump (variable speed).
When entering Sleep Mode, the lower status line in the Local Control Panel shows Sleep Mode.
See also signal flow chart in section 22-2* No Flow Detection.
There are three different ways of using the Sleep Mode function:
1) Systems where the integrated PI controller is used for controlling pressure or temperature e.g. boost systems with a pressure feed back signal applied
to the frequency converter from a pressure transducer. Par. 1-00, Configuration Mode, must be set for Closed Loop and the PI Controller configured for
desired reference and feed back signals.
Example: Boost system.

3. Parameter Description

If no flow is detected, the frequency converter will increase the set point for pressure to ensure a slight over pressure in the system (boost to be set in
par. 22-45, Setpoint Boost).
The feedback from the pressure transducer is monitored and when this pressure has dropped with a set percentage below the normal set point for
pressure (Pset), the motor will ramp up again and pressure will be controlled for reaching the set value (Pset).
2) In systems where the pressure or temperature is controlled by an external PI controller, the wake up conditions can not be based on feedback from
the pressure/temperature transducer as the setpoint is not known. In the example with a boost system, desired pressure Pset is not known. Par. 1-00,
Configuration mode, must be set for Open Loop.
Example: Boost system.

3. Parameter Description

When low power or low speed is detected the motor is stopped, but the reference signal (fref) from the external controller is still monitored and because
of the low pressure created, the controller will increase the reference signal to gain pressure. When the reference signal has reached a set value fwake
the motor restarts.
The speed is set manually by an external reference signal (Remote Reference). The settings (par. 22-3*) for tuning of the No Flow function must be set
to default.

*
Function:
0-100%
Only to be used if par. 1-00, Configuration Mode, is set for Closed Loop and the integrated PI controller is used
for controlling the pressure.
Set the pressure drop allowed in percentage of set point for the pressure (Pset) before cancelling the Sleep
Mode.
NB!
If used in application where the integrated PI controller is set for inverse control (e.g. cooling tower applications) in par. 20-71, PID,
Normal/Inverse Control, the value set in par. 22-44 will automatically be added.
22-45 Set Point Boost
Range:
0%* [-100% - +100%]
Function:
Only to be used if par. 1-00, Configuration Mode, is set for Closed Loop and the integrated PI controller is used.
In systems with e.g. constant pressure control, it is advantageous to increase the system pressure before the
motor is stopped. This will extend the time in which the motor is stopped and help to avoid frequent start/stop.
Set the desired over pressure/temperature in percentage of set point for the pressure (Pset)/temperature before
entering the Sleep Mode.
If setting for 5%, the boost pressure will be Pset*1.05. The negative values can be used for e.g. cooling tower
control where a negative change is needed.
22-46 Maximum Boost Time
Range:
Function:
60 sec.* [0-600 sec.]
Only to be used if par. 1-00, Configuration Mode, is set for Closed Loop and the integrated PI controller is used
for controlling the pressure.
Set the maximum time for which boost mode will be allowed. If the set time is exceeded, Sleep Mode will be
entered, not waiting for the set boost pressure to be reached.
3.20.4. 22-5* End of Curve
The End of Curve conditions occur when a pump is yielding a too large volume to ensure the set pressure. This can occur if there is a leakage in the
distribution pipe system after the pump causing the pump to operate at the end of the pump characteristic, valid for the max. speed set in par. 4-13 or
4-14 Motor Speed High Limit.
In case the feed back is 2.5% of the programmed value in par. 3-03, Maximum Reference (or numerical value of 3-02, Minimum Reference, whichever
is highest) below the set point for the desired pressure for a set time (par. 22-51 End of Curve Delay), and the pump is running with max. speed set in
par. 4-13 or 4-14 Motor Speed High Limit, - the function selected in par. 22-50 End of Curve Function, will take place.
It is possible to get a signal on one of the digital outputs by selecting End of Curve [192] in par. 5-3* Digital Outputs and/or par. 5-4* Relays. The signal
will be present, when an End of Curve condition occurs and the selection in par. 22-50 End of Curve Function, is different from Off. The end of curve
function can only be used when operating with the built-in PID controller (Closed loop in par. 1.00 Configuration Mode).

3.20.6. 22-7* Short Cycle Protection
When controlling refrigeration compressors, often there will be a need for limiting the numbers of starts. One way to do this is to ensure a minimum run
time (time between a start and a stop) and a minimum interval between starts.
This means that any normal stop command can be overridden by the Minimum Run Time function (par. 22-77) and any normal start command (Start/
Jog/Freeze) can be overridden by the Interval Between Starts function (par. 22-76).
None of the two functions are active if Hand On or Off modes have been activated via the LCP. If selecting Hand On or Off, the two timers will be reset
to 0, and not start counting until Auto is pressed and an active start command applied.

command (Start/Jog/Freeze).
The timer will be overridden by a Coast (Inverse) or an External Interlock command.
NB!
Does not work in cascade mode.
3.20.7. 22-8* Flow Compensation
It is sometimes the case that is not possible for a pressure transducer to be placed at a remote point in the system and it can only be located close to
the fan/pump outlet. Flow compensation operates by adjusting the set-point according to the output frequency, which is almost proportional to flow, thus
compensating for higher losses at higher flow rates.
HDESIGN (Required pressure) is the setpoint for closed loop (PI) operation of the frequency converter and is set as for closed loop operation without flow
compensation.
It is recommended to use slip compensation and RPM as unit.
NB!
When flow compensation is used with the Cascade Controller (parameter group 25), the actual set-point will not depend on speed
(flow) but on the number of pumps cut in. See below:

[0]
[1]
*
Function:
Disabled
Enabled
Disabled [0]: Work Point Calculation not active. To be used if speed at design point is known (see table above).
Enabled [1] : Work Point Calculation is active. Enabling this parameter allows the calculation of the unknown
System Design Working Point at 50/60 Hz speed, from the input data set in par.22-83/84, 22-87, 22-88, 22-89
and 22-90.
Example 1: Speed at System Design Working Point is known:
From the data sheet showing characteristics for the specific equipment at different speeds, simply reading across
from the HDESIGN point and the QDESIGN point allows us to find point A, which is the System Design Working Point.
The pump characteristics at this point should be identified and the associated speed programmed. Closing the
valves and adjusting the speed until HMIN has been achieved allows the speed at the no flow point to be identified.
Adjustment of par. 22-81 Square-Linear Curve Approximation then allows the shape of the control curve to be
adjusted infinitely.
Example 2:
Speed at System Design Working Point is not known: Where the Speed at System Design Working Point is
unknown, another reference point on the control curve needs to be determined by means of the data sheet. By
looking at the curve for the rated speed and plotting the design pressure (HDESIGN, Point C) the flow at that
pressure QRATED can be determined. Similarly, by plotting the design flow (QDESIGN, Point D). the pressure HD at
that flow can be determined. Knowing these two points on the pump curve, along with HMIN as described above,
allows the frequency converter to calculate the reference point B and thus to plot the control curve which will
also include the System design Working Point A.

3.21.3. Energy Log, 23-5*
The frequency converter is continuously accumulating the consumption of the motor controlled, based on the actual power yielded by the frequency
converter.
These data can be used for an Energy Log function allowing the user to compare and structure the information about the energy consumption related
to time.
3
There are basically two functions:
-
Data related to a pre-programmed period, defined by a set date and time for start
-
Data related to a predefined period back in time e.g. last seven days within the pre-programmed period
For each of the above two functions, the data are stored in a number of counters allowing for selecting time frame and a split on hours, days or weeks.
The period/split (resolution) can be set in par. 23-50, Energy Log Log Resolution.
The data are based on the value registered by the kWh counter in the frequency converter. This counter value can be read in par. 15-02,kWh Counter,
containing the accumulated value since the first power up or latest reset of the counter (par. 15-06, Reset kWh counter).
All data for the Energy Log are stored in counters which can be read from par. 23-53, Energy Log.
Counter 00 will always contain the oldest data. A counter will cover a period from XX:00 to XX:59 if hours or 00:00 to 23:59 if days.
If logging either the last hours or last days, the counters will shift contents at XX:00 every hour or at 00:00 every day.
Counter with highest index will always be subject to update (containing data for the actual hour since XX:00 or the actual day since 00:00).
The contents of counters can be displayed as bars on LCP. Select Quick Menu, Loggings, Energy Log: Trending Continued Bin / Trending Timed Bin /

3.21.4. Trending, 23-6*
Trending is used to monitor a process variable over a period of time and record how often the data falls into each of ten user-defined data ranges. This
is a convenient tool to get a quick overview indicating where to put focus for improvement of operation.
Two sets of data for Trending can be created in order to make it possible to compare current values for a selected operating variable with data for a
certain reference period, for the same variable. This reference period can be pre-programmed (par. 23-63, Timed Period Start, and par. 23-64, Timed
Period Stop). The two sets of data can be read from par. 23-61, Continuous Bin Data (current) and par. 23-62, Timed Bin Data (reference).
196
MG.11.C5.02 - VLT® is a registered Danfoss trademark
VLT® HVAC Drive Programming Guide
3. Parameter Description
It is possible to create Trending for following operation variables:
-
Power
-
Current
-
Output frequency
-
Motor Speed
The Trending function includes ten counters (forming a bin) for each set of data containing the numbers of registrations reflecting how often the operating
variable is within each of ten pre-defined intervals. The sorting is based on a relative value of the variable.
3
The relative value for the operating variable is
Actual/Rated * 100%.
for Power and Current and
Actual/Max * 100%
for Output Frequency and Motor Speed.
The size of each interval can be adjusted individually, but will default be 10% for each. Power and Current can exceed rated value, but those registrations
will be included in 90%-100% (MAX) counter.
Once a second, the value of the operating variable selected is registered. If a value has been registered to equal 13%, the counter “10% - <20%” will
be updated with the value “1”. If the value stays at 13% for 10s, then “10” will be added to the counter value.
The contents of counters can be displayed as bars on LCP. Select Quick Menu >Loggings: Trending Continued Bin / Trending Timed Bin / Trending
Comparison.
NB!
The counters starts counting whenever the frequency converter is powered-up. Power cycle shortly after a reset will zero the counters.
EEProm data are updated once per hour.

3. Parameter Description
3.21.5. 23-8* Payback counter
The frequency converter includes a feature which can give a rough calculation on payback in cases where the frequency converter has been installed in
an existing plant to ensure energy saving by changing from fixed to variable speed control. Reference for the savings is a set value to represent the
average power yielded before the upgrade with variable speed control.
3
The difference between the Reference Power at fixed speed and the Actual Power yielded with speed control represent the actual saving.
As value for the fixed speed case, the rated motor size (kW) is multiplied with a factor (set in %) representing the power produced at fixed speed. The
difference between this reference power and the actual power is accumulated and stored. The difference in energy can be read in par. 23-83, Energy
Savings.
The accumulated value for the difference in power consumption is multiplied with the energy cost in local currency and the investment is subtracted. This
calculation for Cost Savings can also be read in par. 23-84, Cost Savings.
{
t
Cost Savings = ∑ ( Rated Motor Power ∗ Power Reference Factor )
t=0
− Actual Power Consumption × Energy Cost } − Investment Cost
Break even (payback) occurs when the value read in the parameter turns from negative to positive.
It is not possible to reset the Energy Savings counter, but the counter can be stopped any time by setting par. 28-80, Power Reference Factor , to 0.

3.22.1. 24-0* Fire Mode
NB!
Please note the frequency converter is only one component of the VLT HVAC 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
3
the local fire Authorities. Non-interruption of the frequency converter due to Fire Mode operation may cause over pressure
and result in damage to VLT HVAC Drive system and components, hereunder dampers and air ducts. The frequency
converter itself may be damaged and it may cause damage or fire. Danfoss accepts no responsibility for errors, malfunctions personal injury or any damage to the frequency converter itself or components herein, VLT HVAC Drive
systems and components herein or other property when the frequency converter 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 frequency converter 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 frequency converter’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 par 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 the 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 frequency converter supply. If, whilst the frequency converter is active in Fire Mode, a warranty-affecting
alarm (see parameter 24-09, Fire Mode Alarm Handling) should occur, 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 par 5-3* and 5-4*.
“Fire M was Active” messages can also be accessed in the warning word via serial communication. (See relevant documentation).
The status messages “Fire Mode” can be accessed via the extended status word.

3.23.1. 25-** Cascade Controller
Parameters for configuring the Basic Cascade Controller for sequence control of multiple pumps. For a more application oriented description and wiring
examples, see section Application Examples, Basic Cascade Controller.
To configure the Cascade Controller to the actual system and the desired control strategy, it is recommended to follow the below sequence, starting with
par. 25-0* System Settings and next par. 25-5* Alternation Settings. These parameter can normally be set in advance.
Parameters in 25-2* Bandwidth Settings and 25-4* Staging settings, will often be dependent on the dynamic of the system and final adjustment to be
done at the commissioning of the plant.
NB!
The Cascade Controller is supposed to operate in closed loop controlled by the built-in PI controller (Closed Loop selected in Configu-
ration Mode, par.1-00). If Open Loop is selected in par.1-00 Configuration Mode, all fixed speed pumps will be destaged, but the
variable speed pump will still be controlled by the frequency converter, now as an open loop configuration:

25-05 Fixed Lead Pump
Option:
Function:
Fixed Lead Pump means that the variable speed pump is connected directly to the frequency converter and if a
contactor is applied between frequency converter and pump, this contactor will not be controlled by the frequency converter.
If operating with par. 25-50, Lead Pump Alternation, set to other than Off[0], this parameter must be set to
No [0].
[0]
No
The lead pump function can alternate between the pumps controlled by the two built in relays. One pump must
be connected to the built-in RELAY 1, and the other pump to RELAY 2. The pump function (Cascade Pump1 and
Cascade Pump2) will automatically be assigned to the relays (maximum two pumps can in this case be controlled
from the frequency converter).

3.23.3. 25-2* Bandwidth Manager
Parameters for setting the bandwidth within which the pressure will be allowed to operate before staging/destaging fixed speed pumps. Also includes
various timers to stabilize the control.
3
25-20 Staging Bandwidth [%]
Range:
Function:
10%* [1 - 100 %]
Set the staging bandwidth (SBW) percentage to accommodate normal system pressure fluctuation. In cascade
control systems, to avoid frequent switching of fixed speed pumps, the desired system pressure is typically kept
within a bandwidth rather than at a constant level.
The SBW is programmed as a percentage of par. 3-02 Minimum Reference and par. 3-03 Maximum Reference.
For example, if the set-point is 5 bar and the SBW is set to 10%, a system pressure between 4.5 and 5.5 bar is
tolerated. No staging or de-staging will occur within this bandwidth.
25-21 Override Bandwidth [%]
Range:
Function:
100% = Disabled* [1 – 100%]
When a large and quick change in the system demand occurs (such as a sudden water demand), the system
pressure rapidly changes and an immediate staging or destaging of a fixed speed pump becomes necessary to
match the requirement. The override bandwidth (OBW) is programmed to override the staging/destaging timer
(par. 25-23/25-24) for immediate response.
The OBW must always be programmed to a higher value than the value set in Staging Bandwidth (SBW), par.
25-20. The OBW is a percentage of par.3-02 Minimum Reference and par. 3-03 Maximum Reference..
Setting the OBW too close to the SBW could defeat the purpose with frequent staging at momentary pressure
changes. Setting the OBW too high might lead to unacceptably high or low pressure in the system while the SBW
timers are running. The value can be optimized with increased familiarity with the system. See Override Band-
width Timer, par. 25-25.
MG.11.C5.02 - VLT® is a registered Danfoss trademark
211
VLT® HVAC Drive Programming Guide
3. Parameter Description
To avoid unintended staging during the commissioning phase and fine tuning of the controller, initially leave the
OBW at the factory setting of 100% (Off). When the fine tuning is completed, the OBW should be set to the
desired value. An initial value of 10% is suggested.
25-22 Fixed Speed Bandwidth [%]
3
Range:
Function:
10%* [1 - 100%]
When the cascade control system is running normally and the frequency converter issues a trip alarm, it is
important to maintain the system head. The Cascade Controller does this by continuing to stage/destage the
fixed speed pump on and off. Due to the fact that keeping the head at the setpoint would require frequent staging
and destaging when only a fixed speed pump is running, a wider Fixed Speed Bandwidth (FSBW) is used instead
of SBW. It is possible to stop the fixed speed pumps, in case of an alarm situation, by pressing the LCP OFF or
HAND ON keys or if the signal programmed for Start on digital input goes low.
In case the issued alarm is a trip-lock alarm then the Cascade Controller must stop the system immediately by
cutting out all the fixed speed pumps. This is basically the same as Emergency Stop (Coast/Coast inverse Command) for the Cascade Controller.
25-23 SBW Staging Delay
Range:
Function:
15 sec.* [0-3000 sec.]
Immediate staging of a fixed speed pump is not desirable when a momentary pressure drop in the system exceeds
the Staging Bandwidth (SBW). Staging is delayed by the length of time programmed. If the pressure increases
to within the SBW before the timer has elapsed, the timer is reset.
25-24 SBW Destaging Delay
Range:
Function:
15 sec.* [0-3000 sec.]
Immediate destaging of a fixed speed pump is not desirable when a momentary pressure increase in the system
that exceeds the Staging Bandwidth (SBW). Destaging is delayed by the length of time programmed. If the
pressure decreases to within the SBW before the timer has elapsed, the timer is reset.
212

VLT® HVAC Drive Programming Guide
3. Parameter Description
25-25 OBW Time
Range:
Function:
10 sec.* [0 – 300 sec. ]
Staging a fixed speed pump creates a momentary pressure peak in the system, which might exceed the Override
Bandwidth (OBW). It is not desirable to destage a pump in response to a staging pressure peak. The OBW Time
can be programmed to prevent staging until the system pressure has stabilized and normal control established.
Set the timer to a value that allows the system to stabilize after staging. The 10 second factory setting is appropriate in most applications. In highly dynamic systems, a shorter time may be desirable.
3
25-26 Destage at No-Flow
Option:
Function:
The Destage at No-Flow parameter ensures that when a no-flow situation occurs, the fixed speed pumps will
be destaged one-by-one until the no-flow signal disappears. This requires that No Flow Detection is active. See
par. 22-2*.
If Destage at No-Flow is disabled the cascade controller does not change the normal behavior of the system.

Motor Speed High Limit, par. 4-13 or 4-14, with at least one fixed speed pump in the stop position. When the
programmed value of the timer expires, a fixed speed pump is staged.
25-29 Destage Function
Option:
Function:
The Destage Function ensures that the lowest numbers of pumps are running to save energy and to avoid dead
head water circulation in the variable speed pump. If the Destage Function is set to Disabled [0], the Destage

When adding a fixed speed pump, in order to prevent an overshoot of pressure, the variable speed pump ramps
down to a lower speed. When the variable speed pump reaches the “Staging Speed” the fixed speed pump is
staged on. The Staging Threshold is used to calculate the speed of the variable speed pump when the “cut-in

3. Parameter Description
3.24. Main Menu - Analog I/O Option MCB 109 - Group 26
3.24.1. Analog I/O Option MCB 109, 26-**
The Analog I/O Option MCB 109 extends the functionality of VLT HVAC Drive frequency converters, by adding a number of additional, programmable
analog inputs and outputs. This could be especially useful in Building Management System installations where the frequency converter may be used as
de-central I/O, obviating the need for an outstation and thus reducing cost.
3
Consider the diagram:
This shows a typical Air Handling Unit (AHU). As can be seen, the addition of the Analog I/O option offers the possibility to control all of the functions
from the frequency converter, such as inlet-, return- and exhaust dampers or heating/cooling coils with temperature and pressure measurements being
read by the frequency converter.
NB!
The maximum current for the analog outputs 0-10V is 1mA.
NB!
Where Live Zero Monitoring is used, it is important that any analog inputs not being used for the frequency controller, i.e. being used
as part of the Building Management System decentral I/O, should have their Live Zero function disabled.

converter as standard. See section Clock Settings, par 0-7*.
The Analog I/O option can be used for the control of devices such as actuators or valves, using the Extended Closed loop facility, thus removing control
from the Building Management System. See section Parameters: Ext. Closed Loop – FC 100 par 21-**. There are three independent closed loop PID

4.1.1. Alarms and warnings
A warning or an alarm is signalled by the relevant LED on the front of the frequency converter 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 frequency converter 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 using the [RESET] control button on the LCP control panel.
2.
Via a digital input with the “Reset” function.
3.
Via serial communication/optional fieldbus.
4.
By resetting automatically using the [Auto Reset] function, which is a default setting for frequency converter. see par. 14-20 Reset Mode in VLT
HVAC Drive Programming Guide, MG.11.Cx.yy
NB!
After a manual reset using the [RESET] button on the LCP, the [AUTO ON] button 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).
Alarms that are trip-locked offer additional protection, means that the mains supply must be switched off before the alarm can be reset. After being
switched back on, the frequency converter 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 parameter 14-20 (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 parameter 1-90 Motor Thermal Protection. After an alarm or trip, the motor carries on coasting, and the alarm and warning
flash on the frequency converter. Once the problem has been rectified, only the alarm continues flashing.
