Safety and operating instructions
for drive power converters
(as per: Low Voltage Directive 2006/95/EEC )
1. General
During operation, drive power converters may, depending on their
protection class, have live, bare, moving or rotating parts or hot
surfaces.
Unauthorised removal of covers, improper use, incorrect installation
or operation causes a 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 (comply with
IEC 364, CENELEC HD 384, DIN VDE 0100, IEC 664 and 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 assembly,
installation, commissioning and operation of this product and who
have the relevant qualifications for their work.
2. Proper use in Europe
Drive power converters are components intended for installation in
electrical systems or machines.
When installed in machines, the drive power converter cannot be
commissioned (i.e. commencement of the proper use) until it has
been ensured that the machine meets the provisions of the EC
Directive 2006/42/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 (2004/108/EEC) is complied with.
Drive power converters with a CE label meet the requirements of the
Low Voltage Directive 2006/95/EEC. The harmonised standards for
drive power converters stated in the declaration of conformity are
used.
Technical data and information for connection conditions can be
found on the rating plate and in the documentation, and must be
complied with.
The drive power converters may only be used for safety functions
which are described and explicitly approved.
3. Transport, storage
Information regarding transport, storage and correct handling must
be complied with.
4. Installation
The drive power converter must be protected against
impermissible loads. Especially during transport and
handling, components must not be deformed and/or
insulation distances must not be changed. Touching of
electronic components and contacts must be avoided.
Drive power converters have electrostatically sensitive
components, which 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 live drive power converters, the applicable
national accident prevention regulations must be complied
with (e.g. BGV A3, formerly VBG 4).
The electrical installation must be implemented as per the
applicable regulations (e.g. cable cross-section, fuses, earth
lead connections). Further instructions can be found in the
documentation.
Information regarding EMC-compliant installation – such as
shielding, earthing, location of filters and installation of
cables – can be found in the drive power converter
documentation. These instructions must be complied with
even with CE marked drive power converters. 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 drive power converters 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.
The parameterisation and configuration of the drive power
converter must be selected so that no hazards can occur.
All covers must be kept closed during operation.
7. Maintenance and repairs
After the drive power converter is disconnected from the
power supply, live equipment components and power
connections should not be touched immediately, because of
possible charged capacitors. Observe the applicable
information signs located on the drive power converter.
Further information can be found in this documentation.
The installation and cooling of the equipment must be implemented
according to the regulations in the corresponding documentation.
These safety instructions must be kept in a safe place!

General information
The series NORDAC SK 700E is the follow-on development of the proven vector series. These devices are characterised by
the high modularity and excellent control characteristics.
These devices are provided with non-sensor vector current control system which constantly ensures an optimised voltage-tofrequency ratio in combination with a motor model of an three-phase asynchronous motor. This has the following significance
for the drive: Peak start-up and overload torques at constant speed.
Due to its modular construction, the variously combinable technology units, customer units and special extension units, this
device series is suitable for all possible applications.
Devices for constant load:
Due to the numerous setting options, these inverters are capable of controlling all three-phase motors. The performance range
goes from 1.5kW to 22kW (3~ 380V...480V) with an integrated line filter and from 30kW to 132kW (3~ 380V...480V) with
optional external line filter. The overload capacity of these devices is 200% for 3.5 seconds and 150% for 60 seconds.
Device for quadratically increasing loads SK 700E-163-340-O-VT:
In the performance range 160kW (3~ 380V...480V) a variant for quadratically increasing load is available. This load profile is
typical for fans and various pump applications. In contrast to the devices used for constant load torque, the overload capacity
here is limited to 125%.
NOTE:
The SK 700E with the performance range 30kW to 160kW varies in some technical details from the lower
performance devices. Details can be found in this manual.
This manual is based on the device software V3.4 Rev4 (P707) for the SK 700E. 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/)
The most important amendments in comparison with edition 3910 are the correction of errors and amendments associated with
UL certification.

NORDAC SK 700E Operating Manual
1.4 Safety and installation information
NORDAC SK 700E frequency inverters are equipment for use in industrial high voltage systems and are operated at voltages
that could lead to severe injuries or death if they are touched.

Installation and other work may only be carried out by qualified electricians and when the device is
disconnected. The manual must always be available for these persons and must be complied with.

Local regulations for the installation of electrical equipment as well as for accident prevention must be
complied with.

The equipment continues to carry hazardous voltages for up to 5 minutes after being switched off at the
mains. The equipment may only be opened or the cover or control element removed 5 minutes after the
equipment has been disconnected from the power supply. All covers must be put back in place before the line
voltage is switched back on again.

Even during motor standstill (e.g. caused by a release block, blocked drive or output terminal short circuit), the
line connection terminals, motor terminals and braking resistor terminals may still conduct hazardous voltages.
A motor standstill is not identical to galvanic isolation from the mains.

Attention, even parts of the control card and, in particular, the connection plug for the removable technology
units can conduct hazardous voltages. The control terminals are mains voltage free.

Warning, under certain settings the frequency inverter can start automatically after the mains are switched on.

The circuit boards contain highly-sensitive MOS semiconductor components that are particularly sensitive to
static electricity. Avoid touching circuit tracks and components with the hand or metallic objects. Only the
terminal strip screws may be touched with insulated screwdrivers when connecting the cables.

The frequency inverter is only intended for permanent connection and may not be operated without effective
earthing connections that comply with local regulations for large leak currents (> 3.5mA). VDE 0160 requires
2
the installation of a second earthing conductor or an earthing conductor cross-section of at least 10 mm .

Normal FI-circuit breakers are not suitable as the sole protection in three-phase frequency inverters when
local regulations do not permit a possible DC proportion in the fault current. The standard FI circuit breaker
must comply with the new design as per VDE 0664.

The inverter must be mounted in a switch cabinet that is suitable for its immediate surroundings. In particular it
must be protected from excess humidity, corrosive gases and dirt.

In normal use, NORDAC SK 700E frequency inverters are maintenance free. The cooling surfaces must be
regularly cleaned with compressed air if the ambient air is dusty.
ATTENTION! DANGER TO LIFE!
The power unit can continue to carry voltages for up to 5 minutes after being switched off at the mains.
Inverter terminals, motor cables and motor terminals may carry voltage!
Touching open or free terminals, cables and equipment components can lead to severe injury or death!

Assembly and installation
2.1 Installation
NORDAC SK 700E frequency inverters are available in various sizes depending on the output. When installed in a control
cabinet, the size, power dissipation and perm. ambient temperature must be taken into account to prevent device failures.
The equipment requires sufficient ventilation to protect against overheating. Reference values apply here for the spaces above
and below the frequency inverter within the control cabinet.
(up to and inc. 22kW, above > 100mm, below > 100mm and from and inc. 30kW above > 200mm, below > 200mm)
Electrical components (e.g. cable ducts, contactors, etc.) can be located within these limits. There is a height-dependent
minimum separation distance from the frequency inverter for these components. This distance must be a minimum 2/3 of the
object height. (Example: cable duct 60mm high 2/3 60mm = 40mm gap)
Additional side gaps for devices up to and inc. 55kW are not required. Mounting can be immediately next to each other. The
installation position is normally vertical. It must be ensured that the cooling ribs on the rear of the device are covered with a flat
surface to provide good convection.
Warm air must be vented above the device!

If several inverters are arranged above each other, ensure that the upper air entry temperature limit is not exceeded. (See also
Chapter 7, Technical data). If this is the case, it is recommended that an "obstacle" (e.g. a cable duct) is mounted between the
inverters so that the direct air flow (rising warm air) is impeded.

2.3 UB line filter up to 22kW (accessory)
An additional external line filter can be installed into the line supply of the frequency inverter to maintain the increased noise
suppression level (class B as per EN 55011).
When connecting the line filter, comply with Chapter 2.9 "Wiring guidelines" and 8.3 "EMC". In particular, ensure that the pulse
frequency is set to the default value (P504 = 4/6kHz) and that the maximum motor cable length (30m) is not exceeded and a
shielded motor cable is used.
Mains connection is by means of screw connections at the lower end of the filter. Inverter connection is by means of a fixed
cable of a suitable length (235-385mm).
The filter should be located as close as possible to the inverter; it can be used as a substructure or Book Size component.

When connecting the line filter, comply with Chapter 2.9 "Wiring
guidelines" and 8.3 "EMC". In particular, ensure that the pulse
frequency is set to the default value (P504 = 4/6kHz). The line filter
should be placed as close to the side of the inverter as possible.
The connection is by means of screw connections on the upper
(mains) and lower (inverter) ends of the filter

To reduce input side current harmonics, additional inductivity
can be installed into the line supply to the inverter.
These chokes are specified for a maximum supply voltage of
480V at 50/60 Hz.
The protection class of the chokes is IP00 and they must
therefore be installed in a control cabinet.
For frequency inverters with an output of 45 kW or more, a
line choke is recommended where several devices are being
used, in order to avoid possible adverse effects of one device
on another. In addition, the charging currents (mains voltage
fluctuations) are significantly reduced.

To reduce interference signals from the motor cable or to
compensate for cable capacitance in long motor cables, an
additional output choke can be installed into the inverter
output.
Take care during installation that the pulse frequency of the
frequency inverter is set to 3-6kHz (P504 = 3-6).
These chokes are specified for a maximum supply voltage of
460V at 0-100 Hz.
An output choke should be fitted for cable lengths over
150m/50m (unshielded/shielded). Further details can be found
in Chapter 2.10.4 "Motor cable".

2.7 UB brake resistors (accessory)
During dynamic braking (frequency reduction) of a three phase motor, electrical energy is returned to the frequency inverter. In
order to avoid overcurrent cut-off of the frequency inverter, the integrated brake chopper can convert the returned energy into
heat by connecting an external brake resistor.
For inverter outputs up to 7.5 kW, a standard substructure resistor can be fitted;
it can also be optionally equipped with a heat monitor for additional
thermal protection of the resistor.
This design is no longer possible with higher frequency
inverter outputs. Instead, the chassis brake
resistors (Chapter 2.8) can be used.

During dynamic braking (frequency reduction) of a three phase motor, electrical energy is released and returned to the
frequency inverter. To prevent a safety shut-down of the frequency inverter, the integrated brake
chopper can be activated by the connection of an external brake resistor.
The returned energy is converted into heat, so avoiding a possible overvoltage.
All chassis resistors are UL certified and are not subject to
restrictions in the North American market.
Connection is with screw connectors that are designated +B, B (1.5-22kW) or BR, +ZW (30-160kW), and the safety leads.

NORDAC SK 700E Operating Manual
2.9 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. To meet the limit values of the EMC directives , the following instructions should be complied with.
(1) Ensure that all equipment in the cabinet is securely earthed using short earthing cables that have large cross-sections and
which are connected to a common earthing point or earthing bar. 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.
The PE lead of the motor controlled by the frequency inverter must be connected as directly as possible to the earth
connection of the cooling element, together with the PE of the corresponding frequency inverter mains supply. 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. (See also Chapter 8.3/8.4 EMC guidelines)
(2) Where possible, shielded cables should be used for control loops. The shielding at the cable end should be carefully sealed
and it must be ensured that the wires are not laid over longer distances without shielding.
The shields of analog setpoint cables should only be earthed on one side on the frequency inverter.
(3) 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.
(4) Ensure that the contactors in the cabinet are interference protected, either by RC circuits in the case of AC contactors or by
free-wheeling diodes for DC contactors, for which 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.
(5) Shielded or protected cables should be used for load connections and the shielding/protection should be earthed at both
ends, if possible directly to the frequency inverter PE/shield angle.
(6) If the drive is to be used in an area sensitive to electromagnetic interference, then the use of noise suppression filters is
recommended to limit the cable-dependent and radiated interference from the inverter. In this case, the filter must be
mounted as closely as possible to the frequency inverter and fully earthed.
It is also an advantage if the inverter is installed together with the line filter in an EMC-proof enclosure, with EMC-compliant
cabling. (See also Chapter 8.3/8.4 EMC)
(7) Select the lowest possible switching frequency. This will reduce the intensity of the electromagnetic interference produced 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 Assembly and installation
2.10 Electrical connections
2.10.1 Line and motor connections
WARNING
THESE DEVICES MUST BE EARTHED.
Safe operation of the devices presupposes that qualified personnel mount and operate it in compliance with
the instructions provided in these operating instructions.
In particular, the general and regional mounting and safety regulations for work on high voltage systems
(e.g. VDE) must be complied with as must the regulations concerning professional use of tools and the use
of personal protection equipment.
Dangerous voltages can be present at the line input and the motor connection terminals even when the
inverter is switched off. Always use insulated screwdrivers on these terminal fields.
Ensure that the input voltage source is not live before setting up or changing connections to the unit.
Make sure that the inverter and motor have the correct supply voltage set.
Note:
If synchronising devices are connected or several motors are switched in parallel, the frequency inverter must be
operated with linear voltage/frequency characteristic curves, P211 = 0 and P212 = 0.
The line, motor, brake resistor and control connections are located on the base of the device. To gain access to the terminals,
the device covers (cover and grid) must be removed. The connection terminals are now accessible from the front. All covers
must be put back in place before switching on the supply voltage!
In general, the line, motor and brake resistor cables are connected first as their terminals are located on the bottom circuit
board. The cable inlet is a slit opening on the base of the device.
Note:
when using specific wiring sleeves, the maximum connection cross-section can be reduced.
Pay attention to the following:
1.
Ensure that the voltage source provides the correct voltage and is suitable for the current required (see Chapter 7
Technical data). Ensure that suitable circuit breakers with the nominal current range are inserted between the voltage
source and the inverter.
2.
Connect the line voltage directly to the line terminals L 1 - L2 - L3 and the earth (PE).
3.
A four-core cable must be used to connect the motor. The cable must be connected to the motor terminals U - V - W and
the PE.
4.
If shielded cables are used, then the cable shield can also be applied to as much surface as possible on the shield support
angle.
Note: The use of shielded cables is essential in order to maintain the specified radio interference suppression level. (See
also Chapter 8.4 EMC limit value classes)

Operation and display
The NORDAC SK 700E basic device is supplied with a blanking cover for the technology unit slot and the basic version has no
components for parameterisation or control.
Technology units, customer units and special extension units
Through the combination of modules for the display, technology units and modules with digital and analog inputs, as well as
interfaces, customer units or special extension units, the NORDAC SK 700E can be easily adapted to the requirements of
various applications.
Technology Units (TU) are modules that can be inserted from above for display,
parameterisation and control of the inverter.
Customer Units (CU) are modules inserted inside the inverter in the upper recess.
They are used for control and communication using digital/analog signals or bus
interfaces.
Extension Units (XU) are inserted into the slot at the base of the inverter. Such an
extension unit is required if the speed is to be controlled or positioned by an incremental
(absolute) encoder.
WARNING
Modules should not be inserted or removed unless the device is free of voltage. The slots may only be used
for the applicable modules. The slots are coded to prevent them being mixed up.

3.2.2 Standard I/O
(SK CU1-STD, Option)
The Customer Unit standard I/O provides sufficient control terminals for most
applications and it is fully terminal-compatible with NORDAC vector mc.
There are 1 differential analog input and 4 digital inputs available for control of
the frequency inverter. The analog input can process signals from 0...10V or
0...20mA and/or 4...20mA (with additional burden resistance).
The analog output allows actual operating parameters to be transmitted to a
display device or process control system. The output signal is scalable and
available in the voltage range 0...10V.
By means of the two relay contacts, brake control and even warnings to another
system can be initiated.
The connected inverter can be controlled and parameterised via the interface
RS485. A simple function test of the frequency inverter can be carried out using
NORD CON software. Following successful parameterisation, the complete
data set can be stored as a file.
The digital inputs of the Standard I/O can also be assigned analog functions
(see process controller, Chapter 8.2). Here, input voltages ≥10V are processed
as 10V signals and correspond to 100%. (9V = 90%, ... , 0V=0%)

3.3.1 PosiCon I/O
(SK XU1-POS, Option)
The special extension unit (EXtension Unit) PosiCon I/O is a positioning control
system integrated in the frequency inverter. Previously programmed positions are
reached dynamically and precisely by means of path calculations.
The position acquisition is implemented by an incremental (RS422) or absolute
encoder (SSI protocol).
The encoder can be fitted on the motor or the load, step-up/step-down can be freely
selected.
Note:
Further details can be found in the operating instructions BU 0710,
specially produced for this option.

3.3.2 Encoder I/O
(SK XU1-ENC, Option)
The special extension (EXtension Unit) encoder I/O offers the possibility of
connecting an incremental encoder with a TTL signal level. The incremental
encoder must be mounted directly on the motor shaft.
This accessory enables highly accurate speed control from standstill to double
the rated speed.
This option is especially recommended for lifting applications as it provides the
best load control.

NOTE:
If there are deviations from the standard equipment (Type 5820.0H40, 10-30V encoder, TTL/RS422)
for the motors, please note the accompanying data sheet or consult your supplier.
RECOMMENDATION: For greater operating safety, in particular with long connection cables, we recommend the use of a
higher power supply (15V/24V) and an incremental encoder for 10-30V power supply. The signal level
must remain at 5V TTL.
ATTENTION:
BU 0700 GB-1411
The rotation field of the incremental encoder must correspond to that of the motor. Therefore,
depending on the rotation direction of the encoder to the motor (possibly reversed), a negative sign
number must be set in parameter P301.

General information
Once the power supply has been connected to the frequency inverter, it will be operational after a few moments. In this
condition, the frequency inverter can be set up for the application requirements, i.e. parameterised. A complete and
comprehensive description of each parameter is set out in the following sections.
The motor should only be started with the enable signal after the parameters have been successfully set by qualified personnel.
ATTENTION: The frequency inverter is not equipped with a line main switch and is therefore always live when connected to
the power supply.
4.1 Basic settings
All frequency inverters supplied by Getriebebau NORD are pre-programmed with the factory setting for standard applications
with 4-pole standard motors. For use with other motors, the data from the rating plate of the motor must be input into the
parameters under the menu item >Motor data<.
Recommendation: It is necessary to input the most precise motor data (rating plate) possible for the correct use of the drive
unit. In particular, an automatic stator resistance measurement (P208) should be carried out.

0 = no changes
8 = 2,20 kW

Note:
In this example, the motor must be "star" wired (400V, P207 = 0).
The frequency inverter is pre-programmed at the factory for standard applications using 4-pole DC standard motors. If another
NORD motor is to be used, it can be selected from a motor list in P200. The data is automatically loaded into parameters P201
– P208 and can be compared again with the data from the motor rating plate.
When using other motors, the data from the rating plate of the motor must be input into parameters P201 to P208.
In order to automatically determine the stator resistance, set P208 = 0 and confirm by pressing "ENTER". The value adjusted to
the line resistance will be saved (dependent upon P207).

5.
- Press the key until parameter P113 >Jog frequency< is displayed.
6.
Display
- Press the key to display the actual frequency setpoint (standard factory
setting = 0.0Hz).
7.
- Press the key to set the required frequency setpoint (e.g. 35.0Hz).
8.
- Press the key to store the setting.
9.
- Keep pressing the key until the operating display is reached.
Or press
and
simultaneously to change directly to the operation display.
Use the
key to switch on directly, the frequency inverter then changes directly
to the operating display.
10.
Switch on the frequency inverter using the
key.
The motor shaft starts up and indicates that the inverter output frequency is
reaching the setpoint of 35Hz.
Note:
The desired value is reached after 1.4 seconds (35Hz / 50Hz x 2s). The standard
start-up time is 2 seconds to reach 50Hz (as defined by P102 and P105).
The motor speed (i.e. the frequency) can be adjusted directly using the
keys if necessary. By pressing the
key, the new set value can be saved
directly in P113.
11.
Switch off the frequency inverter using the
key.
The motor is braked and is brought to a controlled stop (this takes 1.4 seconds).
The standard deceleration time is 2 seconds from 50Hz to standstill (defined by
P103, P105).
Note:
The inverter always supplies 0Hz for 0.5 seconds after stopping (P559, >DCTime lag<). If there is a new enable during this period, then this is interrupted.

Parameterisation
There are four switchable parameter sets available during operation. All parameters are always visible. All parameters can be
adjusted "online".
Note:
As there are dependencies between the parameters, it is possible for invalid internal data and operating faults to be
generated temporarily. Only the inactive parameters should be adjusted during operation.
The individual parameters are combined in various parameter sets. The first digit of the parameter number indicates the
assignment to a menu group:
The following main functions are assigned to the menu groups:

levels (arrays).
Note:
Parameter P523 can be used to load the factory settings for all parameters at any time. This can be helpful,
e.g. during the commissioning of a frequency inverter whose parameters no longer correspond with the
factory settings.
Attention:
All parameter settings will be lost, if P523= 1 is set and confirmed with "ENTER".
To safeguard the actual parameter settings, these can be transferred to the ControlBox or ParameterBox
memories.

Acceleration time
0 ... 320.00 s
[ 2.00 ]
> 11kW [ 3.00 ]
> 22kW [ 5.00 ]
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 start-up time can be extended by certain circumstances, e.g. FI overload, setpoint lag, rounding or
if the current limit is reached.
P103 (P)
Deceleration time
0 ... 320.00 s
[ 2.00 ]
> 11kW [ 3.00 ]
> 22kW [ 5.00 ]
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
mode< (P108) or >Ramp smoothing< (P106).
P104 (P)
Minimum frequency
0.0 ... 400.0 Hz
[ 0.0 ]
The minimum frequency is the frequency supplied by the FI as soon as it is enabled and no additional
setpoint is set.
In combination with other setpoints (e.g. analog setpoint or fixed frequencies) these are added to the
set minimum frequency.
This frequency is undershot when
a) the drive is accelerated from standstill.
b) The FI is blocked. The frequency then reduces to the absolute minimum (P505) before it is
blocked.
c) The FI is reversing. The reverse in the rotation field takes place at the absolute minimum
frequency (P505).
This frequency can be continuously undershot if, during acceleration or deceleration, the function
"Maintain frequency" (Function Digital input = 9) is executed.

Brake reaction time
always visible
0 ... 2.50 s
[ 0.00 ]
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 application time, the FI supplies the set absolute minimum frequency (P505) and
so prevents movement against the brake and load drop when stopping.
See also the parameter >Release time< P114
Note:
For the control of electromagnetic braking (especially for lifting operations) an internal relay
should be used,  Function 1, external brake (P434/441).
The minimum absolute frequency (P505) should never be less than 2.0Hz.

P108 (P)
Disconnection mode
always visible
0 ... 12
[1]
This parameter determines the manner in which the output frequency is reduced after "Blocking"
(controller enable  low).
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 down: The actual output frequency is reduced proportionally to the remaining braking time
from P103.
2 = Delayed ramping: as with ramp, however for generational operation the brake ramp is extended,
or for static operation the output frequency is increased. Under certain conditions, this function can
prevent overload 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 = Instant DC braking: The FI switches immediately to the preselected DC current (P109). This DC
current is supplied for the remaining proportion of the >DC brake time< (P110). Depending on the
relationship, actual output frequency to max. frequency (P105), the >Time DC brake on< is
shortened.
The time taken for the motor to stop depends on the application. The time taken to stop depends
on the mass inertia of the load and the DC set (P109).
With this type of braking, no energy is returned to the FI; heat loss occurs mainly in the motor
rotor.
4 = Constant brake distance: The brake ramp is delayed in starting if the equipment is not being
driven at 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 rounding (P106).
5 = Combined braking: Dependent on the actual link voltage (CLV), a high frequency voltage is
switched to the basic mode (linear characteristic curves only, P211 = 0 and P212 = 0). The
deceleration time is retained where possible (P103).  additional motor warming!
6 = Quadratic ramp: The braking 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 applies in field weakening range! The drive is accelerated
and braked using constant electrical power. The course of the ramps depends on the load.
10 = Distance calculator: Constant distance between actual frequency / speed and the set minimum
output frequency (P104).
11 = Constant acceleration power with delay: Combination of functions 2 and 9.
12 = Constant acceleration power with delay (as 11) with additional chopper relief
P109 (P)
DC brake current
0 ... 250 %
[ 100 ]
Current setting for the functions of DC current braking (P108 = 3) and combined braking (P108 = 5).
The correct setting value depends on the mechanical load and the required deceleration time. A higher
setting brings large loads to a standstill more quickly.
A setting of 100% corresponds to a current value as set in parameter P203.
P110 (P)
Time DC-brake on
0.00 ... 60.00 s
[ 2.0 ]
The time during which the motor has the current selected in parameter >DC brake current< applied to it
during the DC braking functions (P108 = 3).
Depending on the relationship, actual output frequency to max. frequency (P105), the >Time DC brake
on< is shortened.
The time starts running with the removal of the enable and can be interrupted by fresh enabling.
P111 (P)
P -factor torque limit
25 ... 400 %
[ 100 ]
Directly affects the behaviour of the drive at torque limit. The basic setting of 100 % is sufficient for
most drive tasks.
If values are too high the drive tends to vibrate as it reaches the torque limit.
If values are too low, the programmed torque limit can be exceeded.

Torque current limit

25 ... 400/ 401 %
[ 401 ]
With this parameter, a limit value for the torque-generating current can be set. 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%, P403/P408) then corresponds to the value set in P112.
The limit value 20% of torque current cannot be undershot by a smaller analog setpoint (P400/405 = 2)
(with P300 = 1, not below 10%)!
401% = OFF is for switching the torque current limit off! This is also the basic setting for the FI.
Note:
For lifting gear applications, no torque limitation must be provided and the parameter
(P112) must be left at the works setting!
P113 (P)
Jog frequency
-400.0 ... 400.0 Hz
[ 0.0 ]
When using the ControlBox or ParameterBox to control the FI, the jog frequency is the starting value
following successful enable.
Alternatively, when control is via the control terminals, the jog frequency can be activated via one of the
digital inputs.
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 the correct sign. The set maximum frequency (P105)
cannot be exceeded and the minimum frequency (P104) cannot be undershot.
P114 (P)
Brake delay off
0 ... 2.50 s
[ 0.00 ]
Electromagnetic brakes have a delayed reaction time during ventilation, which depends on physical
factors. This can lead to the motor running while the brake is still applied, which will cause the inverter
to switch off with an overcurrent report.
This ventilation time can be taken into account in parameter P114 (Braking control).
During the adjustable ventilation time, the FI supplies the set absolute minimum frequency (P505) thus
preventing movement against the brake.
See also the parameter >Brake reaction time< P107 (setting example).
Note:
If the brake ventilation time is set to "0", then P107 is the brake ventilation and reaction
time.

Static boost

[ 100 ]
The static boost affects the current that generates the magnetic field. This is equivalent to the no load

using the motor data. The factory setting of 100% is sufficient for normal applications.
P211 (P)
Dynamic boost
0 ... 150 %
[ 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, the output current is raised too much.
Too low a value will lead to insufficient torque.
P212 (P)
Slip compensation
0 ... 150 %
[ 100 ]
The slip compensation increases the output frequency, dependent on load, to keep the DC
asynchronous motor speed approximately constant.
The factory setting of 100% is optimal when using DC asynchronous motors and correct motor data
has been set.
If several motors (different loads or outputs) are operated with one FI, the slip compensation P212
must be set to 0%. This excludes any negative influences.
This is equally valid for synchronous motors that do not have slip due to their design.
P213 (P)

Oscillation damping
10 ... 400 %
[ 10 ]
With the oscillation damping, idling current harmonics can be damped. Parameter 217 is a measure of
the damping power.
For oscillation damping the oscillation component is filtered out of the torque current by means of a
high pass filter. This is amplified by P217, inverted and switched to the output frequency.
The limit for the value switched is also proportional to P217. The time constant for the high pass filter
depends on P213. For higher values of P213 the time constant is lower.
With a set value of 10% for P217, a maximum of ± 0.045Hz are switched in. At 400% in P217, this
corresponds to ± 1.8Hz
The function is not active in “Servo mode, P300”.
P218
Modulation depth
50 ... 110 %
[ 100 ]
The modulation depth can be changed between 50% and 110%. Values under 100% limit the voltage
at the motor to smaller values than the mains voltage. This is not feasible for typical applications with
three-phase asynchronous motors.
Values greater than 100% increase the voltage available at the output, but also the current harmonics,
which can lead to oscillation in some motors.
With active ISD control (P211 und P212 ≠ 0) this parameter (P215) must remain as "0" in order to
prevent a negative influence on the ISD control.
For drives that require a high starting torque, this parameter provides an option for switching in an
additional current during the start phase. The application time is limited and can be selected at
parameter >Time boost precontrol< P216.
All current and torque current limits which may have been set (P112, P536, P537) are deactivated

P310 (P)
Speed controller P
0...3200 %
[ 100 ]
P-component of the encoder (proportional amplification).
Amplification factor, with which the speed difference is multiplied from the setpoint and actual
frequency. A value of 100% means that a speed difference of 10% produces a setpoint of 10%. Values
that are too high can cause the output speed to oscillate.
P311 (P)
Speed controller I
0...800 % / ms
[ 20 ]
I-component of the encoder (Integration component).
The integration component of the controller completely eliminates any control deviation. The value
indicates how large the setpoint change is per ms. Values that are too small cause the controller to
slow down (reset time is too long).
P312 (P)
Torque current controller P
0...800 %
[ 200 ]
Current controller for the torque current. The higher the current controller parameters are set, the more
precisely the current setpoint is maintained. Excessively high values in P312 generally lead to highfrequency vibrations at low speeds, on the other hand, excessively high values in P313 generally
produce low frequency vibrations across the whole speed range. If the value "Zero" is entered in P312
and P313, then the torque current control is switched off. In this case, only the motor model precontrol
is used.
P313 (P)
Torque current controller I
0...800 % / ms
[ 125 ]
I-component of the torque current controller. (See also P312 >Torque current controller P<)
P314 (P)
Torque current controller limit
0...400 V
[ 400 ]
Determines the maximum voltage increase of the torque current controller. The higher the value, the
greater the maximum effect that can be exercised by the torque current controller. Excessive values in
P314 can specifically lead to instability during transition to the field weakening zone (see P320). The
values for P314 and P317 should always be set roughly the same, so that the field and torque current
controllers are balanced.

Current controller for the field current. The higher the current controller parameters are set, the more

frequency vibrations at low speeds. On the other hand, excessively high values in P316 generally
produce low frequency vibrations across the whole speed range If the value "Zero" is entered in P315

P317 (P)
Field current controller limit
0...400 V
[ 400 ]
Determines the maximum voltage increase of the torque current controller. The higher the value, the
greater is the maximum effect that can be exercised by the field current controller. Excessive values in
P317 can specifically lead to instability during transition to the field reduction range (see P320). The
values for P314 and P317 should always be set roughly the same, so that the field and torque current
controllers are balanced.
P318 (P)
P-Weak
0...800 %
[ 150 ]
The field weakening controller reduces the field setpoint when the synchronous speed is exceeded.
Generally, the field weakening controller has no function; for this reason, the field weakening controller
only needs to be set if speeds are set above the nominal motor speed. Excessive values for P318 /
P319 will lead to controller oscillations. The field is not weakened sufficiently if the values are too small
or during dynamic acceleration and/or delay times. The downstream current controller can no longer
read the current setpoint.
P319 (P)
I-Weak
0...800 % / ms
[ 20 ]
Affects only the field weakening range, see P318 >Field weakening controller P<
P320 (P)
Weak Border
0...110 %
[ 100 ]
The field weakening limit determines at which speed / current the controller will begin to weaken the
field. At a set value of 100% the controller will begin to weaken the field at approximately the
synchronous speed.
If values much larger than the standard values have been set in P314 and/or P317, then the field
weakening limit should be correspondingly reduced, so that the control range is actually available to
the current controller.
P321 (P)
Speed control I brake off

During brake ventilation time (P107/P114), the I-component of the speed controller is increased. This

The ISD control cannot be switched off in this function.
1 = PID actual frequency value: The actual speed of a system is used for speed control. This

possible to use an incremental encoder for speed control that is not mounted directly onto the

2 = Frequency addition: The speed determined is added to the current setpoint value.

Analog 1 input function
BSC
0...18
The FI analog input can be used for various functions. It must be noted that only one of the functions
given below is possible at any time.
0 = Off, the analog input has no function. After the FI has been enabled via the control terminals, it
will supply the set minimum frequency (P104).
1 = Nominal frequency, the given analog range (P402/P403) varies the output frequency between
the set minimum and maximum frequencies (P104/P105).
2 = Torque current limit, based on the set torque current limit (P112), this can be altered by means
of an analog value. 100% setpoint here corresponds to the set torque current limit P112. 20%
cannot be undershot (with P300=1, not below 10%)!
3 = PID current frequency *, is required to build up a control loop. The analog input (actual value) is
compared with the setpoint (e.g. fixed frequency). The output frequency is adjusted as far as
possible until the actual value equals the setpoint. (see Control variables P413 – P415)
4 = Frequency addition *, the supplied frequency value is added to the setpoint.
5 = Frequency subtraction*, the supplied frequency value is subtracted from the setpoint.
6 = Current limit, based on the set current limit (P536), this can be altered via the analog input.
7 = Maximum frequency, the maximum frequency of the FI is set in the analog range. 100%
corresponds to the setting in parameter P411. 0% corresponds to the setting in parameter P410.
The values for the min/max output frequency (P104/P105) cannot be exceeded or undershot.
8 = PID limited current frequency *, like Function 3, PID current frequency, however the output
frequency cannot fall below the programmed minimum frequency value in Parameter P104. (no
change to rotation direction)
9 = PID supervised current frequency *, like Function 3, PID current frequency, however the FI
switches the output frequency off when the minimum frequency P104 is reached.
10 = Servo-Mode Torque, in the Servo mode the motor torque can be set using this function.
11 = Pre-tension Torque, function that enables a value for the anticipated torque requirement to be
entered in the controller (interference factor switching). This function can be used to improve the
load take-up of lift equipment with separate load detection.
12 = Reserved
13 = Multiplication, the setpoint is multiplied with the analog value supplied. The analog value
adjusted to 100% then corresponds to a multiplication factor of 1.
14 = Current value process controller *, activates the process controller, analog input 1 is
connected to the actual value encoder (compensator, air can, flow volume meter, etc.). The
mode (0-10 V or 0/4-20 mA) is set in P401.
15 = Process controller setpoint *: Like Function 14, however the setpoint is specified (e.g. by a
potentiometer). The actual value must be specified using another input.
16 = Process controller precontrol *: Adds an adjustable additional setpoint after the process
controller
Further details regarding the process controller can be found in Chapter 8.2

speed and the guideline speed so that neither of the two drives travel faster in the curve than the
guideline speed.

0 = 0 – 10V limited: An analog setpoint smaller than the programmed adjustment 0% (P402) does
not lead to undershooting of the programmed minimum frequency (P104). Therefore does not
lead to any rotation direction reversal.
1 = 0 - 10V: If a setpoint smaller than the programmed adjustment 0% (P402) is present, this can
cause a change in direction rotation. This allows rotation direction reversal using a simple
voltage source and potentiometer.
E.g. internal setpoint with rotation direction change: P402 = 5V, P104 = 0Hz, Potentiometer 0–
10V  Rotation direction change at 5V in mid-range setting of the potentiometer.
During the reversing moment (hysteresis =  P505), the drive stands still when the minimum
frequency (P104) is smaller than the absolute minimum frequency (P505). A brake that is
controlled by the FI will have entered the hysteresis range.
If the minimum frequency (P104) is greater than the absolute minimum frequency (P505), the
drive reverses when the minimum frequency is reached. In the hysteresis range  P104, the FI
supplies the minimum frequency (P104), the brake controlled by the FI does not enter the
range.

and P402, the FI output switches off.
Once the setpoint is greater than [P402

an output signal again.

frequency setpoint, below 0.6V (2.4mA) output switches off.
3 = - 10V – 10V: If a setpoint smaller than the programmed adjustment 0% (P402) is present, this
can cause a change in direction rotation. This allows rotation direction reversal using a simple
voltage source and potentiometer.
E.g. internal setpoint with rotation direction change: P402 = 5V, P104 = 0Hz, Potentiometer 0–
10V  Rotation direction change at 5V in mid-range setting of the potentiometer.
During the reversing moment (hysteresis =  P505), the drive stands still when the minimum
frequency (P104) is smaller than the absolute minimum frequency (P505). A brake that is
controlled by the FI will not have entered the hysteresis range.
If the minimum frequency (P104) is greater than the absolute minimum frequency (P505), the
drive reverses when the minimum frequency is reached. In the hysteresis range  P104, the FI
supplies the minimum frequency (P104), the brake controlled by the FI does not enter the
range.

If Servo mode is being used (P300), the measured speed will be output via this function.

For drive torques, values between 5V and 10V are output, and for generator torque, values

Using this parameter an adjustment can be made to the analog output for the selected operating zone.
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.

In certain cases, the FI must start up directly when the mains are switched on. This means that P428 =
1  On can be set. If the enable signal is permanently switched on, or equipped with a cable jumper,
the FI starts up immediately.
This function is only possible if the FI is controlled using the digital inputs. (siehe P509)
P429 (P)
Fixed frequency 1
-400 ... 400 Hz
Settings for the fixed frequency.
Following actuation via a digital input and enabling of the FI (right or left), the fixed frequency is used
as a setpoint.
A negative setting value will cause a direction change (based on the Enable rotation direction P420 –
P425).
If several fixed frequencies are actuated at the same time, then the individual values are added with
the correct sign. This also applies to combinations with the jog frequency (P113), analog setpoint (if
P400 = 1) or minimum frequency (P104).
The frequency limits (P104 = fmin, P105 = fmax) cannot be over or undershot.
If none of the digital inputs are programmed for enable (right or left), the simple fixed frequency signal
leads to an enable. A positive fixed frequency corresponds to a right enable, negative left enable.

Errors can cause the frequency inverter to switch off.
The following options are available to reset a malfunction (acknowledge):
1. By switching mains off and on again,
2. By an appropriately programmed digital input (P420 ... P425 = Function 12),
3. by removing the "enable" at the FI (if no digital input is programmed for acknowledgement),
4. By Bus acknowledgement or
5. by P506, the automatic error acknowledgement.

8.2 Process controller
The process controller is a PI controller which can be used to limit the controller output. In addition, the output is scaled as a
percentage of a master setpoint. This provides the option of controlling any downstream drives with the master setpoint and
readjusting using the PI controller.

NORDAC SK 700E Operating Manual
8.3 Electromagnetic compatibility (EMC)
All electrical equipment that have an intrinsic, independent function and are placed on the market as individual units for users
from January 1996 must comply with the EEC directive EEC/89/336EEC . There are three different ways for manufacturers to
display compliance with this directive:
1.
EC declaration of conformity
This is a declaration from the manufacturer stating that the requirements in the applicable European standards for the
electrical environment of the equipment have been met. Only those standards which are published in the Official
Journal of the European Community can be cited in the manufacturer’s declaration.
2.
Technical documentation
Technical documentation can be produced which describes the EMC characteristics of the device. This documentation
must be authorised by one of the “Responsible bodies” named by the responsible European government. This makes it
possible to use standards that are still under preparation.
3.
EC type test certificate
This method only applies to radio transmitter equipment.
SK 700E inverters only have an intrinsic function when they are connected to other equipment (e.g. a motor). The base units
cannot therefore carry the CE mark that would confirm compliance with the EMC directive. Precise details are therefore given
below about the EMC behaviour of this product, based on the proviso that it is installed according to the guidelines and
instructions described in this documentation.
Class 1: General, for industrial environments
Complies with the EMC standard for power drives EN 61800-3, for use in secondary environments (industrial) and when not
generally available.
Class 2: Interference suppressed for industrial environments (operation has own supply transformer)
In this operating class, the manufacturer can certify that his equipment meets the requirements of the EMC directive for
industrial environments with respect to their EMC behaviour in power drives. The limit values correspond to the basic standards
EN 50081-2 and EN 50082-2 for radiation and interference resistance in industrial environments.
Class 3: Interference suppressed for domestic, commercial and light industry environments
In this operating class, the manufacturer can certify that his equipment meets the requirements of the EMC directive for
domestic, commercial and light industry environments with respect to their EMC behaviour in power drives. The limit values
correspond to the basic standards EN 50081-1 and EN 50082-1 for radiation and interference resistance.
Note:
NORDAC SK 700E Frequency inverters are intended exclusively for commercial use. They are therefore not
subject to the requirements of the standard EN 61000-3-2 for radiation of harmonics.

NOTE:
Please note that these limit value classes are only reached if the standard switching frequency (4/6kHz) is being used and the
length of the shielded motor cable does not exceed the limits.
In addition, it is essential to use wiring suitable for EMC. (Control cabinet / Cable clamping)
The motor cable shielding must be applied on both sides (inverter shield angle and the metal motor terminal box). To comply
with Class 3, cable shielding must also be applied at the entry to the control cabinet (EMC screw connection).

In normal use, NORDAC SK 700E frequency inverters are maintenance free. Please note the "general data" in Section 7.1.
8.6.1 Maintenance notes
Dusty environments
If the frequency converter is being used in a dusty environment, then the cooling-vane surfaces should be regularly cleaned with
compressed air. If air intake filters have been built into the control cabinet, then these should also be regularly cleaned or
replaced.
Long-term storage
The frequency inverter must be regularly connected to the supply network for at least 60 min.
If this is not carried out, there is a danger that the frequency inverter may be destroyed.
If a device is to be stored for longer than one year, it must be recomissioned with the aid of an adjustable transformer before
normal connection to the mains.
Long-term storage for 1 - 3 years
30 min with 25% mains voltage
30 min with 50% mains voltage
30 min with 75% mains voltage
