A temperature-dependent resistor placed on the frequency
converter or the 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. The frequency converter prevents a
restart until the cause of the fault has disappeared. To
cancel the trip state, restart the frequency converter. Do
not use the trip state for personal safety.
Trip lock
The frequency converter enters this state in fault situations
to protect itself. The frequency converter requires physical
intervention, for example when there is a short circuit on

NOTICE
Hazardous situations must be identied by the machine
builder/integrator who is responsible for considering the
necessary preventive means. More monitoring and
protective devices may be included, always according to
valid national safety regulations, for example law on
mechanical tools and regulations for the prevention of
accidents.
Crane, lifts, and hoists
The controlling of external brakes must always have a
redundant system. The frequency converter can in no
circumstances be the primary safety circuit. Comply with
relevant standards, for example:
Hoists and cranes: IEC 60204-32.
Lifts: EN 81.
Protection mode
Once a hardware limit on motor current or DC-link voltage
is exceeded, the frequency converter enters protection
mode. Protection mode means a change of the PWM
modulation strategy and a low switching frequency to
minimize losses. This continues for 10 s after the last fault
and increases the reliability and the robustness of the
frequency converter while re-establishing full control of the
motor.
In hoist applications, protection mode is not usable
because the frequency converter is unable to leave this
mode again and therefore it extends the time before
activating the brake, which is not recommended.
Protection mode can be disabled by setting
parameter 14-26 Trip Delay at Inverter Fault to 0, which
means that the frequency converter trips immediately if 1
of the hardware limits is exceeded.
NOTICE
Disabling protection mode in hoisting applications
(parameter 14-26 Trip Delay at Inverter Fault = 0) is
recommended.
Table 1.3 Discharge Time
NOTICE
When using Safe Torque O, always follow the
instructions in VLT® Frequency Converters - Safe Torque
O Operating Instructions.
NOTICE
Control signals from, or internally within, the frequency
converter may in rare cases be activated in error, be
delayed, or fail to occur entirely. When used in situations
where safety is critical, for example when controlling the
electromagnetic brake function of a hoist application, do
not rely on these control signals exclusively.
A=Analog, D=Digital
Terminal 37 is used for Safe Torque O. For Safe Torque O installation instructions, refer to the VLT® Frequency Converters -
Safe Torque O Operating Instructions.
1) Terminal 37 is not included in FC 301 (except enclosure type A1). Relay 2 and terminal 29 have no function in FC 301.
2) Do not connect cable shield.
Very long control cables and analog signals may in rare cases, and depending on installation, result in 50/60 Hz ground
loops due to noise from mains supply cables.
If 50/60 Hz ground loops occur, consider breaking the shield or insert a 100 nF capacitor between shield and enclosure.
To avoid ground currents from both groups to aect other groups, connect the digital and analog inputs and outputs
separately to the common inputs (terminals 20, 55, and 39) of the frequency converter. For example, switching on the digital
input may disturb the analog input signal.

3.1.2 0-1* Set-up Operations
Dene and control the individual parameter set-ups.
The frequency converter has 4 parameter set-ups that can
be programmed independently of each other. This makes
the frequency converter very exible and able to solve
advanced control functionality problems, often saving the
cost of external control equipment. Parameter set-ups can
be used to program the frequency converter to operate
according to 1 control scheme in 1 set-up (for example
motor 1 for horizontal movement) and another control
scheme in another set-up (for example motor 2 for vertical
movement). Alternatively, parameter set-ups can be used
by an OEM machine builder to identically program all their
factory-tted frequency converters for dierent machine
types within a range to have the same parameters. During
production/commissioning, simply select a specic set-up
depending on which machine the frequency converter is
installed on.
The active set-up (that is the set-up in which the frequency
converter is currently operating) can be selected in
parameter 0-10 Active Set-up and is shown in the LCP. By
using multi set-up, it is possible to switch between set-ups
with the frequency converter running, or it can be stopped
via digital input or serial communication commands. If it is
necessary to change set-ups while the frequency converter
is running, ensure that parameter 0-12 This Set-up Linked to
Use parameter 0-51 Set-up Copy to copy a set-up to 1 or all
other set-ups. Stop the frequency converter before
switching between set-ups where parameters marked not
changeable during operation have dierent values. To avoid
conicting settings of the same parameter within 2
dierent set-ups, link the set-ups together using
parameter 0-12 This Set-up Linked to. Parameters which are
not changeable during operation are marked FALSE in theparameter lists in chapter 5 Parameter Lists.

This section describes how to set up a PM motor.
Initial programming steps
To activate PM motor operation, select [1] PM, non-salient
SPM in parameter 1-10 Motor Construction.
Programming motor data
After selecting a PM motor, the PM motor-related
parameters in parameter groups 1-2* Motor Data, 1-3* Adv.Motor Data, and 1-4* Adv. Motor Data II are active.
The necessary data is on the motor nameplate and on the
motor datasheet.
Run a complete AMA using parameter 1-29 AutomaticMotor Adaptation (AMA)[1] Enable Complete AMA.
If a complete AMA is not performed, congure the
following parameters manually:
1.Parameter 1-30 Stator Resistance (Rs)
Enter the line-to-common stator winding
resistance (Rs). If only line-line data is available,
divide the line-line value by 2 to get the linecommon value.
2.Parameter 1-37 d-axis Inductance (Ld)
Enter the line-to-common direct axis inductance
of the PM motor.
If only line-line data is available, divide the lineline value by 2 to get the line-common value.
3.Parameter 1-40 Back EMF at 1000 RPM
Enter the line-to-line back EMF of the PM motor
at 1000 RPM (RMS value). Back EMF is the voltage
generated by a PM motor when no frequency
converter is connected and the shaft is turned
externally. It is normally specied for nominal
motor speed or for 1000 RPM measured between
2 lines. If the value is not available for a motor
speed of 1000 RPM, calculate the correct value as
follows:
If back EMF is, for example, 320 V at 1800 RPM, it
can be calculated at 1000 RPM as follows:
Back EMF = (Voltage/RPM)x1000 =
(320/1800)x1000 = 178.
Test motor operation
1.Start the motor at low speed (100–200 RPM). If
the motor does not turn, check the installation,
general programming, and motor data.
2.Check if the start function in parameter 1-70 StartModets the application requirements.
Rotor detection
This function is the recommended selection for
applications where the motor starts from standstill, for
example pumps or conveyors. On some motors, a sound is
heard when the frequency converter performs the rotor
detection. This does not harm the motor.
Parking
This function is the recommended selection for
applications where the motor is rotating at slow speed, for
example windmilling in fan applications.
Parameter 2-06 Parking Current and parameter 2-07 Parking
Time can be adjusted. Increase the factory setting of these
parameters for applications with high inertia.
Application-specic adjustment when running VVC
+
VVC+ is the most robust control mode. In most situations,
it provides optimum performance without further
adjustments. Run a complete AMA for best performance.

precision at the stop point.
[1]Cnt stop with

Counts the number of pulses,
typically from an encoder, and
generates a stop signal after a preprogrammed number of pulses,
dened in parameter 1-84 Precise
Stop Counter Value, has beenreceived at terminal 29 or terminal
33.
This is direct feedback with oneway closed-loop control.
The counter function is activated

stop, the number of pulses counted
during ramp-down to 0 RPM are
reset.

Same as [2] Cnt stop with reset but
the number of pulses counted

Enter the counter value to be used
in the integrated precise stop
function, parameter 1-83 Precise StopFunction.
The maximum permissible
frequency at terminal 29 or 33 is
110 kHz.
The precise stop functions are advantageous in
applications where high precision is required.
If using a standard stop command, the accuracy is
determined by the internal task time. That is not the case
when using the precise stop function. It eliminates the task
time dependence and increases the accuracy substantially.
The frequency converter tolerance is normally given by its
task time. However, by using its special precise stop
function, the tolerance is independent of the task time
because the stop signal immediately interrupts the
execution of the frequency converter program. The precise
stop function gives a highly reproducible delay from the
stop signal is given until the ramping down starts. Run a
test to nd this delay as it is a sum of sensor, PLC,
frequency converter, and mechanical parts.
To ensure optimum accuracy, there should be at least 10
cycles during ramping down, see:

NOTICE
If [1] S-ramp Const Jerk is selected and the reference
during ramping is changed, the ramp time may be
prolonged to realize a jerk-free movement, which may
result in a longer start or stop time.
Additional adjustment of the S-ramp ratios or switching
initiators may be necessary.
