Safety and operating instructions for frequency inverters
(as per: Low voltage guideline 73/23/EEC )
1. General information
During operation, frequency inverters may have, depending
on their protection class, live, bare, moving or rotating parts or
hot surfaces.
Unauthorised removal of covers, improper use, incorrect
installation or operation leads to the risk of serious personal
injury or material damage.
Further information can be found in this documentation.
All transportation, installation and initialisation and
maintenance work must be carried out by qualified personnel
(compliant with IEC 364, CENELEC HD 384, DIN VDE 0100,
IEC 664 or DIN VDE 0110, and national accident prevention
regulations).
For the purposes of these basic safety instructions, qualified
personnel are persons who are familiar with the erection,
installation, commissioning and operation of this product and
who have the relevant qualifications for their work.
2. Intended use
Frequency inverters are components intended for installation
in electrical systems or machines.
When being installed in machines, the drive power converter
cannot be commissioned (i.e. implementation of the proper
use) until it has been ensured that the machine meets the
provisions of the EC directive 89/392/EEC (machine
directive); EN 60204 must also be complied with.
Commissioning (i.e. implementation of the proper use) is only
permitted when the EMC directive (89/336/EEC) is complied
with.
The frequency inverters meet the requirements of the low
voltage directive 73/23/EEC. The harmonised standards in
prEN 50178/DIN VDE 0160, together with EN 60439-1/VDE
0660 Part 500 and EN 60146/VDE 0558 were applied for the
frequency inverter.
Technical data and information for connection conditions can
be found on the rating plate and in the documentation, and
must be complied with.
3. Transport, storage
Information regarding transport, storage and correct handling
must be complied with.
Climatic conditions in line with prEN 50178 must be complied
with.
These safety instructions must be kept in a safe place!
4. Installation
The installation and cooling of the equipment must be
implemented as per the regulations in the corresponding
documentation.
The frequency inverters must be protected against
impermissible loads. In particular, no components must be
bent and/or the insulation distances changed during transport
and handling. Touching of electronic components and contacts
must be avoided.
Frequency inverters have electrostatically sensitive
components that can be easily damaged by incorrect handling.
Electrical components must not be mechanically damaged or
destroyed (this may cause a health hazard!).
5. Electrical connection
When working on frequency inverters which are connected to
high voltages, the applicable national accident prevention
regulations must be complied with (e.g. VBG 4).
The electrical installation must be implemented as per the
applicable regulations (e.g. cable cross-section, fuses, earth
lead connections). Further information is contained in the
documentation.
Information about EMC-compliant installation – such as
shielding, earthing, location of filters and installation of cables
– can be found in the frequency inverter documentation.
These instructions must also always be observed for drive
frequency inverters CE approval. Compliance with the limit
values specified in the EMC regulations is the responsibility of
the manufacturer of the system or machine.
6. Operation
Systems where frequency inverters are installed must be
equipped, where necessary, with additional monitoring and
protective equipment as per the applicable safety
requirements, e.g. legislation concerning technical equipment,
accident prevention regulations, etc. Modifications to the
frequency inverters using the operating software are
permitted.
After the frequency inverter is disconnected from the power
supply, live equipment components and power connections
should not be touched immediately because of possibly
charged capacitors. Comply with the applicable information
signs located on the frequency inverter.
All covers must be kept closed during operation.
7. Maintenance and repairs

Compliance with the operating instructions is the requirement for error-free operation and
the fulfilment of any warranty claims. You must first read these operating instructions before
working with the device!
These operating instructions contain important information about service and safety. They
must therefore be kept close to the device.
The trio SK 300E frequency inverters are devices for industrial and commercial plants for
operating three-phase asynchronous motors with squirrel-cage rotors. These motors must be
suitable for operation with frequency inverters, other loads must not be connected to the
devices.
The trio SK 300E frequency inverters are devices for stationary installation on machines. All
details regarding technical data and permissible conditions at the installation site must be
complied with.
Commissioning (implementation of the intended use) is not permitted until it has been ensured
that the machine complies with the EMC directive 89/336/EEC and that the conformity of the
end product meets the machine directive 89/392/EEC (note EN 60204).
The construction series NORDAC trioSK 300E is a combination of geared motor and fully functional
frequency inverter, with which process-based solutions can be implemented for decentral system concepts.
The microprocessor-controlled frequency inverters are used to control the speed of three-phase asynchronous
motors.
These devices are provided with sensorless vector current control system which constantly ensures an
optimised voltage-to-frequency ratio based on the simulated operation of a single
motor. This has the following significance for the drive: Peak start-up and overload torques at constant speed.
Due to the modular technology units and customer units, this device series can be customised to meet
individual requirements of customers.
Due to the numerous setting options, all three-phase motors can be operated. The output ranges from 0.55 to
4.0kW (3~ 380V...480V), 0.37 to 2.2kW (3~ 200V…240V) and 0.37 to 1.1kW (1~ 200V…240V) with
integrated line filter. The overload capacity is 150% for 30 seconds and 3 seconds for 200% peak loads.
The manual is based on the device software V1.9 R0 (P707) of the NORDAC trio SK 300E. If the frequency
inverter used has a different version, this may lead to some differences. If necessary, you can download the
current manual from the Internet (http://www.nord.com).

1.6 Nomenclature / Type code
The NORDAC trio SK 300E frequency inverter has the same nomenclature as other NORDAC frequency
inverters. The information contained therein can be determined in the same way. The type classification of the
frequency inverter contains the device type, the nominal output, data on mains voltage, the noise suppression
filter, protection class and any special device designs. The nomenclature of the adapter unit, which represents
the link between the motor and frequency inverter, can be found in the designation of the geared motor. This
clearly identifies a drive unit with SK 300E. The nomenclature contains the abbreviation of the adapter unit,
version and variant of the components, the protection class and the motor winding circuits.
NOTE
The nomenclature must always be provided in orders and for service and support cases!

There are no restrictions in both protection classes regarding the function of the available adapter units,
technology units or customer units (see the applicable chapters). The type designation of the SK 300E and the
modules in the protection class IP66 is given an additional code "-C" (coated → coated board) to differentiate
the IP55 and IP66 protection classes.
IP55 design
:
The IP55 design of the SK 300E is generally available as the standard design. Both variants (motor-
integrated, close to motor) are available here. In addition, all adapter units, technology units and customer
units are available for this design.
IP66 design
:
The IP66 design is a modified option compared to the IP55 design. Both variants (motor-integrated, close to
motor) are also available here. The modules available to the IP66 design (adapter units, technology units and
customer units) have the same functionalities as the corresponding IP55 design modules.
Note
The modules for the IP66 design are identified by an additional "-C" and are modified according to the
following special measures!
Special measures:
• Coated circuit boards
• Low pressure tests
Æ A free M12 screwed connection is required for low pressure testing. Following successful
testing, a membrane valve is inserted here. These screw connections are therefore not
available to the customer.
• Membrane valve for pressure compensation during temperature changes

Commissioning
The wall-mounting kit (SK WMK-DA1) is a
modular design system, i.e. an adapter unit
must be selected first (SK TI 0/1 or SK TI 0/2)
so that the SK 300E frequency inverter can be
fitted to the wall-mounting kit.
When delivered, the wall-mounting kit with the
SK 300E is ready for connection to mains,
motor and control cables. The frequency
inverter only needs to be pushed on after the
cables are connected.
Different datasets from the frequency inverter
and "electronic name plate" will be displayed in
the operating display (E8.6) and by the red
LED during initial commissioning only. This
display serves to inform the operator; the
message is acknowledged by an Enable signal
and the datasets are then synchronised. After
the factory settings are loaded (P523) and the
motor data are set, the frequency inverter is
ready to be switched on.

2.3.5 Mounting the adapter unit
The SK 300E frequency inverter and the (SK TI 0/1 (-C) or SK TI 0/2 (-C)) adapter unit are always completely
mounted and tested when a trio drive (gears + motor + frequency inverter) is delivered. The adapter unit can
also be ordered separately for subsequent mounting on an existing motor or to replace an older motor-
mounted trio frequency inverter.
Note
However, the IP66-conform SK 300E must be mounted at NORD as special measures have to be
implemented. IP66 components retrofitted on site cannot ensure that this protection class is
guaranteed.
The module "Adapter unit" (SK TI 0/1 (-C) or SK TI 0/2 (-C)) contains the following components:
• Cast enclosure (dependent on type of adapter unit)
• customer interface unit (circuit board)
• M12 socket with system connector for RS485 interface
• Screw accessories for attaching the customer interface unit
• Pre-fabricated cable for motor and PTC connections
Procedures:
1. Screw the M12 socket into the connection unit in the cast enclosure, ensuring that it is tight.
2. Mount the cast enclosure on the terminal box stub of the NORD motor with the existing screws in place of
the terminal box. Position the cast enclosure with the dome facing the motor A-side. Retain the motor's
terminal block. Check the adaptability for different motor manufacturers.
3. After the bridges for the correct motor circuit are set, connect the pre-fabricated cables for motor
connection and PTC connection to the respective connection points on the motor.
4. After the cables for the motor connection and PTC are connected to the appropriate terminals on the
customer interface unit (pin assignment, see Chap. 2.6.1 ), the customer interface must be mounted with
the screw accessories in the cast enclosure. It must be ensured that the insulation foil lies on the inner side
of the cast enclosure dome. Both tabs must be pointing to the inside of the cast enclosure.
5. Connect the M12 socket system connector to the appropriate slot (see Fig. 2)

2.3.6 Mounting the SK 300E frequency inverter
The frequency inverter must first be removed before it can be electrically connected. To do this, undo the 4
fastening screws (Fig. 1) so that the frequency inverter can be lifted off vertically (Fig. 2). After connecting the
supply voltage, the frequency inverter must be vertically reattached (Fig. 3), beginning with the plugs on the
rating plate side which ensure that the inverter is positioned correctly. Further information about attaching
customer units can be found in Chap. 3.3.3 “Mounting the customer unit”
In order to achieve the maximum protection class IP55 / IP66, it must be ensured that all fastening screws of
the frequency inverter are tightened in the specified sequence from screw 1 to screw 4 and with the torque
specified in the table below. Use appropriate screwed connections for the connection line cable cross-section.
Dissipation of heat generated by the inverter occurs via convection . The driven motor must have normal
ventilation. Heat dissipation must not be hindered by significant contamination.
A cover plate with 2 LEDs is normally located on the top side of the frequency inverter. These LEDs show the
status of the frequency inverter. Note that the green LED constantly lights when the mains voltage is applied,
and the red LED according to the error message, e.g. 5 flashes - pause - 5 flashes, etc. for the error E005.

2.3.7 Retrofitting an SK 300E frequency inverter
The SK 300E frequency inverter can only be mounted on existing motors when the dimensions of the terminal
box stub matches the dimensions of the adapter unit SK TI 0/1 (-C) or SK TI 0/2 (-C). In order to guarantee the
maximum protection class IP55 / IP66 of the frequency inverter for the entire trio unit, the protection class of
the motor must be modified accordingly.
The adapter unit can be directly attached to size 80 - 100 NORD motors, an additional adapter plate/spacer
with additional seal/cable is required for the sizes 63 - 71 and 112.
Important! The adaptability for other types of motor must be checked individually!
If a trio SK 300E is fitted on site without assistance on an existing motor, the notes regarding Adapter unit
assignment in Chap. 2.6.1 must be complied with.
2.4 Painting
The SK 300E frequency inverter and the corresponding adapter unit are covered in a black powder coating.

2.5 Wiring guidelines
The frequency inverter has been developed for use in an industrial environment. In this environment, high
levels of electromagnetic interference can influence the frequency inverter. In general, correct installation
ensures safe and problem-free operation. Should limit values in excess of the EMC guidelines be required,
then the following guidelines may be useful.
(1) Ensure that all devices are securely earthed using short earthing cables that have large cross-sections
and which are connected to a common earthing point or earthing rail. It is especially important that
every control device connected to the frequency inverters (e.g. an automation device) is connected,
using a short cable with large cross-section, to the same earthing point as the inverter itself. Flat
conductors (e.g. metal clamps are preferable, as they have a lower impedance at high frequencies.
(2) The PE cable for the motor controlled via the frequency inverter should be connected directly to the
earthing connection linked to the enclosure together with the PE for the relevant frequency inverter
feeder. The presence of a central earthing bar in the control cabinet and the grouping together of all PE
conductors to this bar normally ensures safe operation.
(3) Where possible, shielded cables should be used for control loops. Carefully terminate cable ends and
ensure that the wires do not run over longer sections unshielded.
(4) The shields of analogue setpoint cables should only be earthed on one side on the frequency inverter.
(5) The control cables should be installed as far as possible from power cables, using separate cable ducts
etc. Where cables cross, an angle of 90° should be ensured as far as possible.
(6) Ensure that the contactors in the cabinet are interference protected, either by RC circuits in the case of
DC contactors or by free-wheeling diodes for AC contactors, whereby the interference traps must be positioned on the contactor coils. Varistors for over-voltage limitation are also effective. This
interference suppression is particularly important when the contactors are controlled by the relay in the
frequency inverter.
(7) Use shielded or armoured cable for the load connections and earth the shielding/armour at both ends (if
the motor is not integrated). If possible, directly at the inverter PE.
(8) A noise suppression filter is always present in the standard device. If the frequency inverter is mounted
directly on the motor, then noise suppression grade Class B1 is achieved. If the frequency inverter is
mounted close to the motor (e.g. wall mounted), noise suppression grade Class A1 is achieved with a
motor cable length of up to 15m (shielded cable).
(9) Select the lowest possible pulse frequency. This reduces the intensity of the electromagnetic
interference generated by the frequency inverter.
The safety regulations must be complied with under all circumstances when
installing the frequency inverter!
NOTE
The control cables, line cables and motor cables must be laid separately. In no case should they be
laid in the same protective pipes/installation ducts.
The test equipment for high voltage insulations must not be used on cables that are connected to the
frequency inverter.

2.6.2 Important information for single phase operation (1~230V)
1. Mains supply is implemented via terminals L1 (L) and L2 (N) for 0.37-0.75kW SK 300E, or L3 (L) and L2
(N) for 1.1kW SK 300E.
This is important for the correct function of the brake rectifier, amongst others.
2. Higher input currents occur with single phase operation. (Chap. 9.2)
3. The mains voltage monitoring must be switched off (Parameter P538 = 0).

[21]
(without customer unit), 1 digital input is available. This
should normally be used as the PTC input and is set up
as the factory setting.
Switching on can take place directly with the supply voltage (P428 "Automatic start up" 2 = immediate with
mains), via a bus connection, with the ParameterBox, the potentiometer option or with the NORD CON
operating software. If additional control signals are required, then the device must be upgraded with a
customer unit (Basic I/O - SK CU2-BSC, Standard I/O - SK CU2-STD).
If a different digital input is used for the PTC when a customer unit is added, then the relevant parameter
P420...P424 of the digital input must be set to the set value 13.
2.6.4 Electromechanical motor brake
Motor
PTC
An output voltage is generated by the frequency inverter at the terminals -Br/+Br to actuate an
electromechanical motor brake (see Chap. 2.6.1 Assignments for the adapter unit). This is dependent on the
supply voltage present in the frequency inverter. The allocation is as follows:
Mains voltage / AC voltage Brake coil voltage (DC)
400V ~ 180V =
460V ~ - 480V ~ 205V =
230V ~ 105V =
The allocation of the correct brake or brake coil voltage must be taken into account in the design with
reference to the frequency inverter mains voltage.

2.7 Brake resistor
2 Assembly and installation
During dynamic braking (frequency reduction) of a three-phase
motor, electrical energy is returned to the inverter. In order to
avoid overcurrent switch-off of the frequency inverter, the
integrated brake chopper can convert the returned energy into
heat by connecting an external braking resistor.
2 screw connections, which should be fitted with the appropriate
seals, are enclosed for mounting the braking resistor on the
frequency inverter (M20 for the cable and M12 for the holder).
Suitable installation material is provided to mount the brake
resistor on the adapter unit TI 0/2.
CAUTION
The braking resistance and all other metal components can heat up to temperatures above 70°C.
When mounting, sufficient distance from neighbouring components must be maintained. When working
on the components, allow sufficient cooling time beforehand

General information
The NORDAC trio SK 300E can be used in hazardous areas with a suitable modification. It is important that all
safety information given in the operating instructions are strictly complied with for person and property reasons.
This is essential to avoid hazards and damage.
Qualified personnel
It is assumed that all work regarding transport, mounting, installation, commissioning and maintenance is
carried out by qualified personnel. Qualified personnel are those persons who, based on their education,
experience, training and knowledge of applicable standards, specifications, accident prevention regulations
and operating conditions, are authorised to implement the relevant activities required to commission the
frequency inverter. In addition, knowledge of first aid measures and the local rescue facilities is necessary.
ATTENTION
All work must be carried out only when the system is in an electrically voltage-free state.
If the frequency inverter is connected to a motor and a gear, the Ex designations of the motor and
gear must also be taken into account!
Safety information
The increased danger in areas with combustible dust requires that the general safety and commissioning
instructions are strictly complied with. The drive must comply with the specifications in the
6052101

Project outline No.
cause severe or even lethal injuries to persons and significant damage to property.
It is absolutely essential that the persons authorised to use these motors and frequency inverters in hazardous
areas are trained in their correct use.
ATTENTION
The mains voltage must always be switched off and secured against being switched on again
before opening the frequency inverter to connect the electrical lines or any other work!
Higher temperatures than the maximum permitted surface temperature of the enclosure may be
present inside the frequency inverter and motor. The frequency inverter must therefore never be
opened in hazardous dust atmospheres or removed from the motor!

2.8.3 Commissioning information
The frequency inverter and motor are suitable for use in Zone 22 according to their designation - nonconductive dusts.
The designation is as follows:
II 3D T125°C
In Zone 22, the cable entries must meet at least protection class IP 55. Unused apertures must be sealed with
blind plugs (minimum protection class IP 55).
The motors are protected against overheating by the frequency inverter. This is implemented by evaluation of
the motor PTC by the frequency inverter. To ensure this function, the digital input 1 must be set to the function
"PTC" (P420 = 13). In addition, it must be ensured that a NORD motor is selected from the motor list (P200).
If a motor from a different manufacturer is used, the motor parameter data (P201 to P207) must be compared
with the motor name plate. In addition, the frequency inverter must be parameterised so that the motor cannot be
operated with a speed greater than 3000 rpm. The "maximum frequency" for a four pole motor must be set to a
value smaller than or equal to 100Hz (P105 ≤ 100). The maximum permissible drive speed of the gears must also
be taken into account here. In addition, the "I²t-Motor" monitoring must be switched on in parameter P535=1.

This data is based on a four pole motor. Normally,
the value may only be so big that a motor speed of
3000 rpm is not exceeded.
If a NORD motor is used, the preset motor data can
be called up.
If a motor from another manufacturer is used, the
motor data on the rating plate must be entered.
The digital input 1 must be parameterised as the PTC
to ensure temperature monitoring of the motor.

Parameterisation with the ControlBox
The parameterisation of the frequency inverter can take place in the various operating states. All parameters
can always be changed online. Switching to the parameter mode occurs in different ways depending upon the
operating states and the enabling source.
1. If there is no enable (if necessary, press the STOP key ) via the ControlBox, control terminals or a
serial interface, it is still possible to switch to the parameterisation mode directly from the operating
value display with the value keys
2. If an enable is present via the control terminals or a serial interface and the frequency inverter is
producing an output frequency, it is also possible to switch to the parameterisation mode directly from
the operating value display using the value keys
3. If the frequency inverter is enabled via the ControlBox (START key ), the parameterisation mode
can be reached by pressing the START and ENTER keys (

Profibus allows numerous different automation devices to exchange data. PLC's, PC's, operating and
monitoring devices can all communicate via a uniform bus in serial bit mode.
PROFIBUS DP is primarily used for communication between sensor and actuator where system response
needs to be very fast. PROFIBUS DP is a suitable alternative to expensive 24-volt parallel signal transmission
and transmission of measured values. This type of PROFIBUS, which is optimised to speed, is used for
instance for operating frequency inverters on automation devices.
Data exchange is specified in DIN 19245 Part 1 and 2 and application-specific upgrades in Part 3 of this
standard. Within the European field bus standardisation process, PROFIBUS is integrated into the European
field bus standard pr EN 50170.
The termination resistor for the last bus participant is located in the Profibus standard plug.

for voltage and not several inverters! The frequency inverter with the shortest cable distance to the
ParameterBox should be selected for this.
Communication via RS485
With connection of several frequency inverters in series (as diagram below), ensure that the ParameterBox is
the first or last participant in the bus system. A termination resistor (approx. 120

6 Commissioning
6.1 Basic settings
The NORDAC trio SK 300E is already set up so that the assigned 4-pole standard motor can be operated
without further presetting.
The frequency inverter is not equipped with a line main switch and is therefore always live when connected to
the power supply. It waits with a blocked output until an enable signal occurs.
Attention
If a digital input is not programmed for enable and the parameter P428 is changed to 2 (=
"Immediate with mains“), the motor will start immediately
The following options for an enable signal are available:
1) An enable signal is generated by pressing the start key when a ParameterBox is connected.
See "Initial check with ParameterBox“on Page 73 .
2) When connected to a PC, an enable can be generated with the START key in the "NORD CON" control
software (see Chapter 5 "NORD CON software", Page 70).
3) An "Enable right" is implemented with the factory setting if a control input is configured, e.g. digital input
2 on the CU Basic I/O or Standard I/O (terminal 22), with the internal 15V supply voltage (terminal 42).
4) By changing the "Automatic start up" parameter P428 to 2 (= "Immediate with mains"), this enable
occurs as soon as the mains voltage is switched on. The requirement for this is that no digital input has
been parameterised for Enable.
Note
In delivery condition, only the most important parameters are visible for eventual parameter
changes. Should it be necessary to change other parameters as well, such as e.g. motor data when
using a different motor, then parameter P003 "Supervisor Mode" must be set to 1, so that all
parameters are visible (see also parameter P003
Visible parameters in delivery condition:

ATTENTION! The data are based on the parameter data factory settings.
1.) With CU "Basic I/O" or "Standard I/O":
a. Connect electronic enable:
Set control terminal [22] to a high signal, e.g. terminal [42].
b. Set an analog voltage setpoint (0-10V) between the control terminals [12] and [14] after the frequency
inverter is ready for operation (dependent on the setting in P428).

2.) Without CU
a. Set jog frequency in P113 (e.g. 25 Hz). To be able to set the parameter, "Supervisor Mode" must
first be switched on (to "1") in P003.
b. Connect electronic enable:
Set control terminal [21] to a high signal, e.g. terminal [42], +15V'. The requirement for this is that
digital input 1 is programmed for function [1] "Enable right". In the factory setting, digital input 1 is
programmed for function [13] to "PTC input". The reason is that each trio SK 300E must have PTC

7.1 Supervisor mode
The Supervisor Mode is used to simplify operation of the frequency inverter. This mode allows parameters

7.2 Electronic name plate
In addition to the storage capacity in the frequency inverter, the trio SK 300E also contains an additional
storage component in the adapter unit. This means that, after the frequency inverter is parameterised, the
respective data set is present both in the frequency inverter and the adapter unit.
Should a different (e.g. newer) frequency inverter be mounted on the motor, then the data in the adapter unit
will be transferred to the inverter automatically. New data transfer is shown in the display. This message can
be acknowledged via the display device or by switching on and off once. The new frequency inverter is then
ready to switch on with the previous parameter data set.
This "
Electronic name plate" means that a defective device can be replaced very rapidly. This prevents long
downtimes with new parameterisation and optimisation.
7.3 Array parameter display
Some parameters have the option of displaying settings and views over
several levels (arrays). After the parameter is selected, the array level is
displayed and must then also be selected.
When using the ParameterBox, SK-PAR-..., (figure right), the array level
selection options appear in the top right of the display.
Attention
When using the ControlBox in combination with an SK 300E,
only the first array level is displayed for the array parameters.
Further array levels are not displayed with the ControlBox.
It is
only possible in combination with the ParameterBox to
display all array levels of the individual array parameters!

Acceleration time is the time corresponding to the linear frequency rise from 0Hz to the set
maximum frequency (P105). If an actual setpoint of <100% is being used, the acceleration time is
reduced linearly according to the setpoint set.
The acceleration time can be extended by certain circumstances, e.g. FI overload, setpoint lag,
ramp smoothing or if the current limit is reached.
Deceleration time is the time corresponding to the linear frequency reduction from the set maximum
frequency to 0Hz (P105). If an actual setpoint <100% is being used, the deceleration time reduces
accordingly.
The deceleration time can be extended by certain circumstances, e.g. by the selected >Switch-off

P106 Ramp smoothing
0 ... 100 %
[ 0 ]
This parameter enables a rounding of the acceleration and deceleration ramps. This is necessary for
applications where soft, but dynamic speed change is important.
A rounding is carried out for every setpoint change.
The value to be set is based on the set acceleration and deceleration time, however values <10%
have no effect.
P107 Brake reaction time
0 ... 2.50 s
[ 0.0 ]
Electromagnetic brakes have a physically-dependent delayed reaction time when actuated. This can
lead to load drops during lifting applications, as the brake delays in taking over the load.
This reaction time can be taken into account under parameter P107 (Braking control).
Within the adjustable reaction time, the inverter supplies the set absolute minimum frequency (P505)
and so prevents movement against the brake and load drop when stopping.
P108 Disconnection mode
0 ... 9
[ 1 ]
This parameter determines the manner in which the output frequency is reduced after "Blocking"
(controller enable
0 = Voltage disable: The output signal is switched off immediately. The FI no longer supplies
an output frequency. In this case, the motor is braked only by mechanical friction.
Immediate switching on again of the FI can lead to error switch off.
1 = Ramp: The actual output frequency is reduced proportionally to the remaining braking time
from P103.
2 = Delayed ramping: As in Ramp Down, however the braking ramp is extended for
generational operation and the output frequency is increased for static operation. Under
certain conditions, this function can prevent overvoltage switch off or reduce brake
resistance power dissipation.
Note: This function must not be programmed if defined deceleration is required, e.g. with
lifting mechanisms.
3 = Immediate DC braking: The FI switches immediately to the preselected DC current
(P109). This direct current is supplied for > Time DC brake on < (P110).
4 = Constant braking distance: The deceleration ramp acts with a delay, if not moved with
the maximum output frequency (P105). This leads to a similar braking distance from
various frequencies.
Note: This function cannot be used as a positioning function. This function should not be
used with a ramp smoothing (P106).
5 = Combined braking: Dependent on the actual dc-link voltage, a high frequency voltage is
switched to the basic mode (linear characteristic curves only, P211 = 0 and P212 = 0). The
braking time is retained where possible (P103).
6 = Quadratic ramp: The deceleration ramp does not have a linear course, but is square.
7 = Quadratic ramp with delay: Combination of functions 2 and 6
8 = Quadratic combined braking: Combination of functions 5 and 6
9 = Constant acceleration power: Only valid for field weakening range! The drive is
accelerated and braked using constant electrical power. The course of the ramps depends
on the load.

P109 DC current brake
0 ... 250 %
[ 100 ]
Current setting for direct current braking (P108= 3) and combined braking (P108= 5) functions.
The correct setting value depends on the mechanical load and the required braking time. A higher
setting brings large loads to a standstill more quickly.
The 100% setting relates to a current value as stored in the >Nominal current< parameter P203.
P110 DC braking time on
0 ... 60.00 s
[ 2.0 ]
The time that the motor is applied, during the direct current braking (P108= 3) function, with the
current selected in the >DC braking current< parameter (P109).
Depending on the ratio of actual output frequency to max. frequency (P105), the >DC braking time<
is reduced.
The time starts with the removal of the enable and can be interrupted by fresh enabling.
P112 Torque current limit
25 ... 400 % / 401
[ 401 ]
With this parameter, a limit value can be set for the torque generating current. This can prevent
mechanical overloading of the drive. It cannot provide any protection against mechanical blockages
(movement to stops). A slipping clutch which acts as a safety device must be provided.
The torque current limit can also be set over an infinite range of settings using an analog input.
The maximum setpoint (compare adjustment 100%, P402, P408) then corresponds to the value set
in P112.
The limit value 20% of current torque cannot be undershot by a smaller analog setpoint
(P400/405=2).
401 = OFF is for switching the torque current limit off! This is also the basic setting for the FI.
P113 Jog frequency
-400.0...400.0 Hz
[ 0.0 ]
When using the
value following successful enable if it is greater than the minimum frequency.
When controlling via control terminals, the jog frequency can be switched on via one of the digital
inputs (P420-424= jog frequency >15<). None of the digital inputs may be programmed for enable
(function 1 or 2).
The setting of the jog frequency can be done directly via this parameter or, if the FI is enabled via
the keyboard, by pressing the ENTER key. In this case, the actual output frequency is set in
parameter P113 and is then available for the next start.
NOTE: Specified setpoints via the control terminals, e.g. jog frequency, fixed frequencies or analog
setpoints, are generally added with correct sign. The set maximum frequency (P105) cannot
be exceeded in this case, and the minimum frequency (P104) cannot be undershot.

[100]
The dynamic boost affects the torque generating current and is therefore a load-dependent
parameter. The factory 100% setting is also sufficient for typical applications.
Too high a value can lead to overcurrent in the FI. Under load therefore, the output voltage will be
raised too sharply. Too small a value leads to low torque.
P212 Slip compensation

P418 Function analog output
0 ... 52
[ 0 ]
Analog functions:
An analog voltage (0 to + 10 V) can be taken from the control terminals (max. 5 mA). Various
functions are available, the following generally applies:
0 Volt analog voltage always corresponds to 0% of the selected value.
10 V always corresponds to the motor nominal value (unless otherwise stated) multiplied by the
P419 standardisation factor, e.g.
0 = No function, no output signal at the terminals.
1 = Actual frequency, the analog voltage is proportional to the FI output frequency.
2 = Actual speed, this is the synchronous speed calculated by the FI based on the existing
setpoint. Load-dependent speed fluctuations are not taken into account.
3 = Current, the effective value of the output current supplied by the FI.
4 = Torque current, displays the motor load torque calculated by the FI. (100% = P112)
5 = Voltage, the output voltage supplied by the FI.
6 = DC Link voltage, the DC voltage in the FI. This is not based on the motor rated data. 10
Volt, standardised at 100%, is equivalent to 850 Volt DC (400V devices) or 450 Volt DC
(230V devices)!
P419 can be used for modification of the required working range. The maximum analog
output (10V) corresponds to the standardisation value of the appropriate selection.
7 = Value from P542 External control, the analog output can be set using parameter P542
independently of the actual operating status of the FI to 0.0 ... 10.0V.
8 = … 14 reserved
30 = Actual set fre quency before ramp, shows the frequency produced by any upstream
controllers (ISD, PID, etc.). This is then the set frequency for the power level adapted via
the acceleration or deceleration ramp (P102, P103).

Analog functions P418 (= 0 ... 14, 30, 31)
Using this parameter an adjustment can be made to the analog output for the selected operating
range. The maximum analog output (10V) corresponds to the standardisation value of the
appropriate selection.
If therefore, at a constant working point, this parameter is raised from 100% to 200%, the analog
output voltage is halved. 10 Volt output signal then corresponds to twice the nominal value.
For negative values the logic is reversed. A setpoint value of 0% will then produce 10V at the
output and -100% will produce 0V.

The settings 3 to 5 and 11 work with 10% hysteresis, i.e. the relay contact closes (function 11 opens)
when the limit value is reached and opens (function 11 closes) when a 10% smaller value is
undershot. This behaviour can be inverted with a negative value in P435.
Setting / Function
0 = No function
1 = External brake, to control a brake on the motor. The relay switches at the
set absolute minimum frequency (P505, default: 2 Hz). A setpoint delay
should be programmed for typical brakes (see P107).
NOTE: In the SK 300E, a DC voltage is generated for a brake and
supplied at the terminals -Br and +Br. The relay contact should generally
be used with a special brake voltage.
2 = Inverter is working, the closed relay contact indicates voltage at the FI
output (U - V - W).
3 = Current limit*, based on the setting of the motor nominal current in P203.
This value can be adjusted with the standardisation (P435).
4 = Torque current limit *, based on motor data settings in P203 and P206.
Signals a corresponding torque load. This value can be adjusted with the
standardisation (P435).
5 = Frequency limit *, based on motor nominal frequency setting in P201.
This value can be adjusted with the standardisation (P435).
6 = Level with Setpoint, indicates that the FI has completed the frequency
increase or decrease. Setpoint frequency = actual frequency! After the
contact is closed, the setpoint must change by at least 1 Hz.
Æ
Setpoint not reached - contact opens
7 = Fault, general Fault message. Fault is or not yet acknowledged.
Æ
Operational - contact closes
8 = Warning: general warning, a limit value was reached that could lead to a
later shutdown of the FI.

11 = Torque current limit/ current limit active (warning), limit value in P112
is reached. P435 has no significance. Hysteresis = 10%.

parameter P541 (Bit 0), independently of the actual operating status of
the FI.
