1.4 Safety Precautions
WARNING
HIGH VOLTAGE
Frequency converters contain high voltage when connected to AC mains input, DC supply, or load sharing. Failure to perform installation, start-up, and maintenance by qualied personnel can result in death or serious injury.
Only qualied personnel must perform instal-
lation, start-up, and maintenance.
Before performing any service or repair work,
use an appropriate voltage measuring device to make sure that there is no remaining voltage on the frequency converter.
WARNING
UNINTENDED START
When the drive is connected to AC mains, DC supply, or load sharing, the motor can start at any time. Unintended start during programming, service, or repair work can result in death, serious injury, or property damage.

Set-up
Parameter settings in 2 set-ups can be saved. Change between the 2 parameter set-ups and edit 1 set-up, while another set-up is active.
Slip compensation
The frequency converter compensates for the motor slip by giving the frequency a supplement that follows the measured motor load keeping the motor speed almost constant.
Smart logic control (SLC)
The SLC is a sequence of user-dened actions executed when the associated user-dened events are evaluated as true by the SLC.
Thermistor
A temperature-dependent resistor placed where the temperature is to be monitored (frequency converter or motor).
Trip
A state entered in fault situations, for example, if the frequency converter is subject to an overtemperature or when the frequency converter is protecting the motor, process, or mechanism. Restart is prevented until the cause of the fault does not exist and the trip state is canceled by activating reset or, sometimes, by being programmed to reset automatically. Do not use trip for personal safety.
Trip lock
A state entered in fault situations when the frequency converter is protecting itself and requiring physical intervention, for example, if the frequency converter is subject to a short circuit on the output. A locked trip can only be canceled by cutting o mains, removing the cause of the fault, and reconnecting the frequency converter. Restart is prevented until the trip state is canceled by activating reset or, sometimes, by being programmed to reset automatically. Do not use trip lock for personal safety.
VT characteristics
Variable torque characteristics used for pumps and fans.

3.1.2 0-1* Dene and Set-up Operations
A complete set of all parameters controlling the frequency converter is called a set-up. The frequency converter contains 2 set-ups: Set-up 1 and set-up 2. Furthermore, a xed set of factory settings can be copied into 1 or both set-ups.
Some of the advantages of having more than 1 set-up in the frequency converter are:
Run the motor in 1 set-up (active set-up) while
updating parameters in another set-up (edit set­up).
Connect the 2 motors (1 at a time) to the
frequency converter. Motor data for the 2 motors can be placed in the 2 set-ups.
Rapidly change settings of the frequency
converter and/or the motor while the motor is running. For example, ramp time or preset references via bus or digital inputs.
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.

1-01 Motor Control Principle
Motor speed is determined by applying a speed
reference or by setting the wanted speed when
in hand-on mode.
Open loop is also used if the frequency
converter is part of a closed-loop control system
based on an external PI controller providing a
speed reference signal as output.
NOTICE!
When set for Closed Loop, the commands Reversing and Start Reversing do not
reverse the direction of the motor.
A reference from the built-in PI controller
determines the motor speed. The built-in PI
controller varies the motor speed as of a closed-
loop control process (for example, constant
pressure or ow). Congure the PI controller in
parameter group 20-** Drive Closed Loop.

1-14 to 1-17 VVC+ PM
For permanent magnet (PM) motors with
surface-mounted (non-salient) magnets.
Refer to parameter 1-14 Damping Gain to
parameter 1-17 Voltage lter time const. for
details about optimizing the motor
operation.
For permanent magnet (PM) motors with
interior (salient) magnets, with inductance
saturation control.
The default control parameters for VVC+ PM motor control core are optimized for applications and inertia load in the range of 50>Jl/Jm>5. Jl is load inertia from the application and Jm is machine inertia. For low inertia applications (Jl/Jm<5), it is recommended that parameter 1-17 Voltage lter time const. is increased with a factor of 5–10. Sometimes, parameter 14-08 Damping Gain Factor should also be reduced to improve performance and stability. For high-inertia applications (Jl/Jm>50), increase
parameter 1-15 Low Speed Filter Time Const. and parameter 1-16 High Speed Filter Time Const. to improve
performance and stability. For high load at low speed (<30% of rated speed), it is recommended that parameter 1-17 Voltage Filter Time Const. is increased due to non-linearity in the inverter at low speed.
1-14 Damping Gain
Range: Function:

The parameter stabilizes the PM motor to ensure
smooth and stable operation. The value of
damping gain controls the dynamic performance
of the PM motor. Low damping gain results in
high dynamic performance and a high value
results in a low dynamic performance. The
dynamic performance is related to the motor data
and load type. If the damping gain is too high or
low, the control becomes unstable.

3.2.9 1-7* Start Adjustments
Parameters for conguring special motor start features.
1-70 Start Mode
This parameter is valid since software version 2.80 and later
versions. Use this parameter to select the PM motor start mode
which is to initialize the VVC+ control core for previously free-
running PM motors. This parameter is active for PM motors in
VVC+ mode only if the motor is stopped (or running at low
speed).
Option: Function:
[0] Rotor Detection The rotor detection function estimates the
electrical angle of the rotor and uses the
angle as a starting point. This option is
the standard selection for automation
frequency converter applications. If the
ying start function detects that motor is
running at low speed or is stopped, the
frequency converter can detect the rotor
position (the angle). The frequency
converter then starts the motor from that
angle.
[1] * Parking The parking function applies DC current
across the stator winding and rotates the
rotor to electrical zero position. This
function is typically selected for HVAC
applications. If the ying start function
detects that motor is running at low
speed or is stopped, the frequency
converter sends out a DC current to park
the motor at an angle. The frequency
converter then starts the motor from that
angle.

1-73 Flying Start
This function makes it possible to catch a motor that is spinning
freely due to a mains drop-out. Flying start searches in clockwise
direction only. If not successful, a DC brake is activated. If PM-
enabled options are selected, parking is carried out if the speed
is below 2.5–5% of nominal speed, in the time set in
parameter 2-07 Parking Time.
If the speed estimate comes out below 2.5–5% of nominal speed,
the parking function is engaged (see parameter 2-06 Parking
Current and parameter 2-07 Parking Time). Otherwise, the
frequency converter catches the motor at that speed and
resumes normal operation.
The ying start function used for PM motors is based on an
initial speed estimation. The speed is always estimated as the
rst thing after an active start signal is given.
Current limitations of the ying start principle used for PM
motors:
The speed range is up to 100% nominal speed or the
eld weakening speed (whichever is lowest).
For high inertia applications (that is, where the load
inertia is more than 30 times larger than the motor
inertia).
The motor is energized with
parameter 2-00 DC Hold/Motor Preheat Current
during start delay time.
The frequency converter is coasted during
start delay time (frequency converter o).

Terminal 27 digital input parameter 5-12 Terminal 27 Digital Input has [2] Coast inverse as default setting. If
there is no 24 V to terminal 27, [Hand On] does not start the motor. If 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 is stored as the rst element in parameter 4-63 Bypass Speed To [Hz] (array). Repeat this procedure for each resonance band identied at the ramp-up (maximum of 3 can be adjusted).
5. When maximum speed has been reached, the motor automatically begins to ramp down. Repeat this procedure when speed is leaving the resonance bands during the deceleration. The actual frequencies registered when pressing [OK] are stored in parameter 4-61 Bypass Speed From [Hz].
6. When the motor has ramped down to stop, press [OK]. The parameter 4-64 Semi-Auto Bypass Set-up automatically resets to o. The frequency converter stays in hand on mode until [O] or [Auto On] is pressed.

3.9.2 13-0* SLC Settings
To activate, deactivate, and reset the smart logic control sequence, use the SLC settings. The logic functions and
33
Smart logic control (SLC) is a sequence of user-dened actions (see parameter 13-52 SL Controller Action [x]) executed by the SLC when the SLC evaluates the associated user-dened event (see parameter 13-51 SL Controller Event [x]) as true. Events and actions are each numbered and linked in pairs. This means that when [0] event is fullled (attains the value true), [0] action is executed. After executing this action, the conditions of [1] event is evaluated. If it is evaluated as true, [1] action is executed, and so on. Only 1 event is 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
comparators are always running in the background, which opens for separate control of digital inputs and outputs.

To enable the smart logic control to start when a start
command is present, for example, via a digital input,

are 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 as true, the SLC executes [0] action and starts evaluating [1] event. It is possible to program from 1–20 events and actions. When the last event/action has been executed, the sequence starts over again from [0] event/[0] action.
Figure 3.13 Example with 3 Event/Actions
Starting and stopping the SLC
To start or stop the SLC, select [1] On or [2] O in parameter 13-00 SL Controller Mode. The SLC always starts
in state 0 (where it evaluates [0] event). The SLC starts when the start event (dened in parameter 13-01 Start
Event) is evaluated as true (if [1] On is selected in parameter 13-00 SL Controller Mode). The SLC stops when the stop event (parameter 13-02 Stop Event) is true. Parameter 13-03 Reset SLC resets all SLC parameters and
starts programming from the beginning.

Table 3.11 No-ow Detection
No-ow detection is based on the measurement of speed and power. For a certain speed, the frequency converter calculates the power at no-ow. This coherence is based on the adjustment of 2 sets of speed and associated power at no-ow. Monitoring power enables detection of no-ow conditions in systems with uctuating suction pressure, or of the pump having a at characteristic towards low speed. The 2 sets of data must be based on measurement of power at approximately 50% and 85% of maximum speed with the valves closed. The data is programmed in parameter group 22-3* No-Flow Power Tuning.

3.15.4 22-4* Sleep Mode
Sleep mode allows the frequency converter to stop itself in situations where the system is in balance. This function saves energy and prevents excessive pressure, water excessively cooled in cooling towers, and building pressuri­zation problems in the system. This is also important as some applications prevent the frequency converter from adjusting the motor down to low speed. This might damage pumps, cause insucient lubrication in gearboxes, and make fans unstable.
The sleep controller has 2 important functions:
1. The ability to go to sleep at the right time.
2. The ability to abandon sleep mode at the right time.
The goal is to keep the frequency converter in sleep mode as long as possible to avoid cycling the motor on and frequently, and also keep the controlled system variable within the acceptable range.
The sequence when running sleep mode in open loop:
1. The motor speed is less than the speed set in parameter 22-47 Sleep Speed [Hz]. The motor runs longer than the time duration set in parameter 22-40 Minimum Run Time. The sleep condition lasts longer than the time set in parameter 22-48 Sleep Delay Time.
2. The frequency converter ramps the motor speed down to parameter 1-82 Min Speed for Function at Stop [Hz].
3. The frequency converter activates parameter 1-80 Function at Stop. The frequency converter is now in sleep mode.
4. The frequency converter compares the speed setpoint with parameter 22-43 Wake-Up Speed [Hz] to detect a wake-up situation.
5. The speed setpoint is greater than parameter 22-43 Wake-Up Speed [Hz]. The sleep condition has lasted longer than the time set in parameter 22-41 Minimum Sleep Time. The wake­up condition lasts longer than the time set in parameter 22-49 Wake-Up Delay Time. The frequency converter is now out of sleep mode.
6. Go back to speed open-loop control (ramp motor speed up to the speed setpoint).
