4.1.3 Missing Motor Phase Detection
The Missing Motor Phase Function (4-58 Missing Motor
Phase Function) is enabled by default to avoid motor
damage in the case that a motor phase is missing. The
default setting is 1,000 ms, but it can be adjusted for a
faster detection.
4.1.4 Mains Phase Imbalance Detection
Operation under severe main imbalance conditions
reduces the lifetime of the motor. Conditions are
considered severe if the motor is operated continuously
near nominal load. The default setting trips the frequency
converter in case of mains imbalance (14-12 Function at
Mains Imbalance).
4.1.5 Switching on the Output
Adding a switch to the output between the motor and the
frequency converter is permitted. Fault messages may
appear. Enable flying start to catch a spinning motor.
4.1.6 Overload Protection
Torque Limit
The torque limit feature protects the motor against
overload, independent of the speed. Torque limit is
controlled in 4-16 Torque Limit Motor Mode and or
4-17 Torque Limit Generator Mode and the time before the
torque limit warning trips is controlled in 14-25 Trip Delay
at Torque Limit.
Current Limit
The current limit is controlled in 4-18 Current Limit and the
time before the frequency converter trips is controlled in
14-24 Trip Delay at Current Limit.
Speed Limit
Min. speed limit: 4-11 Motor Speed Low Limit [RPM] or
4-12 Motor Speed Low Limit [Hz] limit the operating speed
range to for instance between 30 and 50/60Hz.
Max. speed limit: (4-13 Motor Speed High Limit [RPM] or
4-19 Max Output Frequency limit the max output speed the
frequency converter can provide.
ETR
ETR is an electronic feature that simulates a bimetal relay
based on internal measurements. The characteristic is
shown in Illustration 4.1.
Voltage Limit
The inverter turns off to protect the transistors and the
intermediate circuit capacitors when a certain hard-coded
voltage level is reached.
Overtemperature
The frequency converter has built-in temperature sensors
and reacts immediately to critical values via hard-coded
limits.
4.1.7 Locked Rotor Protection
There may be situations when the rotor is locked due to
excessive load or some other factors (bearing, or
application create locked rotor situation). This leads to
overheating of motor winding (free movement of rotor is
required for proper cooling). The frequency converter is
able to detect the locked rotor situation with open loop
PM flux control, and PM VVC+
 control (30-22 Locked Rotor
Protection).
4.1.8 Automatic Derating
The frequency converter constantly checks for critical
levels:
• Critical high temperature on the control card or
heatsink
• High motor load
• High DC-link voltage
• Low motor speed
As a response to a critical level, the frequency converter
adjusts the switching frequency. For critical high internal
temperatures and low motor speed, the frequency
converters can also force the PWM pattern to SFAVM.
NOTICE
The automatic derating is different when 14-55 Output
Filter is set to [2] Sine-Wave Filter Fixed.
4.1.9 Automatic Energy Optimisation
Automatic energy optimisation (AEO), directs the frequency
converter to continuously monitor the load on the motor
and adjust the output voltage to maximise efficiency.
Under light load, the voltage is reduced and the motor
current is minimised. The motor benefits from increased
efficiency, reduced heating, and quieter operation. There is
no need to select a V/Hz curve because the frequency
converter automatically adjusts motor voltage.
4.1.10 Automatic Switching Frequency
Modulation
The frequency converter generates short electrical pulses
to form an AC wave pattern. The carrier frequency is the
rate of these pulses. A low carrier frequency (slow pulsing
rate) causes noise in the motor, making a higher carrier
frequency preferable. A high carrier frequency, however,
generates heat in the frequency converter which can limit
the amount of current available to the motor. The use of
insulated gate bi-polar transistors (IGBT) means very highspeed switching.

Automatic switching frequency modulation regulates these
conditions automatically to provide the highest carrier
frequency without overheating the frequency converter. By
providing a regulated high carrier frequency, it quiets
motor operating noise at slow speeds, when audible noise
control is critical, and produces full output power to the
motor when the demand requires.
4.1.11 Automatic Derating for High Carrier
Frequency
The frequency converter is designed for continuous, full
load operation at carrier frequencies between 3.0 and 4.5
kHz. A carrier frequency higher than 4.5 kHz generates
increased heat in the frequency converter and requires the
output current to be derated.
An automatic feature of the frequency converter is loaddependent carrier frequency control. This feature allows
the motor to benefit from as high a carrier frequency as
the load permits.
4.1.12 Power Fluctuation Performance
The frequency converter withstands mains fluctuations
such as transients, momentary dropouts, short voltage
drops and surges. The frequency converter automatically
compensates for input voltages ±10% from the nominal to
provide full rated motor voltage and torque. With auto
restart selected, the frequency converter automatically
powers up after a voltage trip. And with flying start, the
frequency converter synchronises to motor rotation prior
to start.
4.1.13 Resonance Damping
High frequency motor resonance noise can be eliminated
through the use of resonance damping. Automatic or
manually selected frequency damping is available.
4.1.14 Temperature-controlled Fans
The internal cooling fans are temperature controlled by
sensors in the frequency converter. The cooling fan often is
not running during low load operation or when in sleep
mode or standby. This reduces noise, increases efficiency,
and extends the operating life of the fan.
4.1.15 EMC Compliance
Electromagnetic interference (EMI) or radio frequency
interference (RFI, in case of radio frequency) is disturbance
which can affect an electrical circuit due to electromagnetic induction or radiation from an external source.
The frequency converter is designed to comply with the
EMC product standard for drives IEC 61800-3 as well as the
European standard EN 55011. To comply with the emission
levels in EN 55011, the motor cable must be shielded and
properly terminated. For more information regarding EMC
performance, see chapter 5.2.1 EMC Test Results.
4.1.16 Galvanic Isolation of Control
Terminals
All control terminals and output relay terminals are galvanically isolated from mains power. This means the controller
circuitry is completely protected from the input current.
The output relay terminals require their own grounding.
This isolations meets the stringent protective extra-low
voltage (PELV) requirements for isolation.
The components that make up the galvanic isolation are
• Power supply, including signal isolation
• Gate drive for the IGBTs, the trigger transformers
and optocouplers
• The output current Hall Effect transducers
4.2 Custom Application Features
These are the most common features programmed for use
in the frequency converter for enhanced system
performance. They require minimum programming or set
up. Understanding that these features are available can
optimie a system design and possibly avoid introducing
redundant components or functionality. See the product
specific Programming Guide, for instructions on activating
these functions.
4.2.1 Automatic Motor Adaptation
Automatic motor adaptation (AMA) is an automated test
procedure used to measure the electrical characteristics of
the motor. AMA provides an accurate electronic model of
the motor. It allows the frequency converter to calculate
optimal performance and efficiency with the motor.
Running the AMA procedure also maximises the automatic
energy optimisation feature of the frequency converter.
AMA is performed without the motor rotating and without
uncoupling the load from the moto
