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-dened actions executed
when the associated user-dened 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.
+
VVC
If compared with standard voltage/frequency ratio control,
voltage vector control (VVC+) improves the dynamics and
the stability, both when the speed reference is changed
and in relation to the load torque.
The frequency converter can be programmed from the LCP
or from a PC via the RS485 COM port by installing the MCT
10 Setup Software. Refer to chapter 1.5 Additional Resources

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.

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

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-dened
actions (see parameter 13-52 SL Controller Action [x])
executed by the SLC when the SLC evaluates the
associated user-dened event (see parameter 13-51 SLController Event [x]) as true. Events and actions are each
numbered and linked in pairs. This means that when [0]
event is fullled (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.

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.

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 (dened 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 whenthe stop event (parameter 13-02 Stop Event) is true.

starts programming from the beginning.

3.9.3 13-1* Comparators
Comparators are used for comparing continuous variables
(such as output frequency, output current, and analog
input) to xed preset values.
Figure 3.14 Comparators
In addition, there are digital values that are compared to
xed time values. See the explanation in
parameter 13-10 Comparator Operand. Comparators are
evaluated once in each scan interval. Use the result (true
or false) directly. All parameters in this parameter group
are array parameters with index 0–5. Select index 0 to
program comparator 0, select index 1 to program
comparator 1, and so on.
Use the result (true or false) from timers directly to dene
an event (see parameter 13-51 SL Controller Event), or as
boolean input in a logic rule (see parameter 13-40 Logic
Rule Boolean 1, parameter 13-42 Logic Rule Boolean 2, or
parameter 13-44 Logic Rule Boolean 3). A timer is only false
when started by an action (for example [29] Start timer 1)
until the timer value entered in this parameter has elapsed.
Then it becomes true again.
All parameters in this parameter group are array
parameters with index 0–2. Select index 0 to program
timer 0, select index 1 to program timer 1, and so on.
Combine up to 3 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 parameter 13-40 Logic
Rule Boolean 1, parameter 13-42 Logic Rule Boolean 2, and

The results of parameter 13-40 Logic Rule Boolean 1,
parameter 13-41 Logic Rule Operator 1, and

The outcome (true/false) of this calculation is combined
with the settings of parameter 13-43 Logic Rule Operator 2
and parameter 13-44 Logic Rule Boolean 3, yielding the nal
result (true/false) of the logic rule.

No-ow detection
This function is used for detecting a no-ow situation in pump systems where all valves can be closed. Can be used both
when controlled by the integrated PI controller in the frequency converter or an external PI controller. Program the actual
conguration in parameter 1-00 Conguration Mode.
Carry out no-ow tuning before setting the PI controller parameters.
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 insucient 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 atStop [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).
The sequence when running sleep mode in closed loop:
1.The frequency converter goes into boost status if
the following conditions are met.
