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 installation and cooling of the equipment must be implemented
according to the regulations in the corresponding documentation.

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.

These safety instructions must be kept in a safe place!

NORDAC SK 700E Operating Manual

1 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
the installation of a second earthing conductor or an earthing conductor cross-section of at least 10 mm2.

 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!

6 Subject to technical alterations BU 0700 GB-1411

CAUTION

 Children and the general public must be kept away from the equipment!
 The equipment may only be used for the purpose intended by the manufacturer. Unpermitted

modifications and the use of spare parts and additional equipment that has not be bought from or
recommended by the equipment manufacturer can lead to fire, electric shock and injury.

 Keep these operating instructions in an accessible location and ensure that every operator uses it!

Warning: This product is covered under marketing classification IEC 61800-3. In a domestic environment, this product can

cause high frequency interference, which may require the user to take appropriate measures.

An appropriate measure would be the inclusion of a recommended line filter.

2 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.

2.4 Chassis line filter (accessory)

In contrast to the line filter described in Chapter 2.3, the HLD 110 (up
to 110kW) has a UL acceptance for the North American market.

The interference noise suppression level of class A is achieved with
up to a maximum motor cable length of 50m, and class B with motor
cables of up to 25m.

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

2.5 Line choke (accessories)

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.

2.6 Output choke (accessories)

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".

The protection class of the chokes is IP00 and they must
therefore be installed in a control cabinet.

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.

2.8 Chassis brake resistors (accessory)

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.
For overload protection, a thermal switch is located close to

a brake resistor. The switch is freely available via the
screw connectors (2 x 4mm2). The switching capacity is
limited to 250VAC/10A, 125VAC/15A and 30VDC/5A.

NORDAC SK 700E Operating Manual

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.

2.9 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!

16 Subject to technical alterations BU 0700 GB-1411

2 Assembly and installation

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.

2.10 Electrical connections

2.10.1 Line and motor connections

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 L1 - 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)

parameterisation and control of the inverter.

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.

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.

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.

3 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.

transmission principle is a single master system with cyclical polling. A maximum of 31 slaves
(or 62 A/B slaves) can be operated on an up to 100m long unshielded two-wire cable in any
network structure (tree/line/star). The AS interface cable (yellow) transmits data and energy
while a second two-wire cable can be used for a small auxiliary voltage (24V). Addressing is
implemented via the master, which can also provide other management functions, or via a
separate addressing device. The 4 bit reference data (per direction) are cyclically transmitted
with an effective error protection at a maximum cycle time of 5ms.

Detailed information can be found in the operating instructions BU 0090, or contact the supplier
of the frequency inverter.

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%)

3.2.5 BUS customer units

(SK CU1-USS, SK CU1-CAN/-RJ, SK CU1-PBR Option)

In addition to data connections, all Bus customer units also provide conventional
digital inputs and outputs.

By means of a relay contact, brake control and even warnings to another system
can be initiated.

The digital input has a 2.5V switching threshold for the evaluation of the
temperature sensor. The input can, however, also be used for an emergency stop
function.

All BUS switching components have the same basic design. However, the
Profibus Option has an RTS signal output on connector X6.3.83 in addition to the
data leads. In addition, the Profibus module also has a second set of data
connections (X6.4) and a DIP switch for the termination resistors at the front.

Note: Further details can be found in the applicable operating instructions for the

Bus systems,
Profibus  BU 0020 DE, CANnord  BU 0060 DE, USS  BU 0050 DE

Note: The BUS customer units include two SK8 shielding clips which can be used

to provide a better shielding connection of the bus cable to the shield angle of
the SK 700E.

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,

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.

Connection details can also be found in Chapter 3.5.

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.

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).

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.

4.2 Basic operation - Quick start guide

... with ControlBox (Option SK TU1-CTR)

The simplest procedure to prepare the frequency inverter for operation is described below. For this operation, jog frequency

5 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:

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.

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.

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).

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

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

cannot be exceeded and the minimum frequency (P104) cannot be undershot.

P114 (P)

Brake delay off

always visible

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

overcurrent; too low a value to a motor torque that is too low.
For simple measurement, this parameter can be set to "Zero". Pressing the ENTER key initiates the

automatic measurement between two motor phases. In the FI, the resistance on the line is measured
on the basis of the delta or star circuit (P207) and the value saved.

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

P211 (P)

Dynamic boost

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

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

This is equally valid for synchronous motors that do not have slip due to their design.

[ 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

three-phase asynchronous motors.

Values greater than 100% increase the voltage available at the output, but also the current harmonics,

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

[ 1 ]

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

17 = Reserved
18 = Curve travel control: The slave transmits its actual speed to the master via the analog input (or

BUS, P547/548). This then calculates the actual setpoint speed from its own speed, the slave

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

guideline speed.

*) The limits of these values are set by the parameters >Minimum frequency auxiliary setpoints<

P410 and >Maximum frequency auxiliary setpoints< P411.

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.

2 = 0 – 10V controled: If the minimum

adjusted setpoint (P402) is undershot by
10% of the difference value from P403
and P402, the FI output switches off.
Once the setpoint is greater than [P402

3 = - 10V – 10V: If a setpoint smaller than the programmed adjustment 0% (P402) is present, this

0 = No function, no output signal at terminals.
1 = Actual frequency, the analog voltage is proportional to the frequency at the FI output.
2 = Speed, this is the synchronous speed calculated by the FI based on the existing setpoint. Load-

dependent speed fluctuations are not taken into account.
If Servo mode is being used (P300), the measured speed will be output via this function.

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.
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!

7 = Value of P542, the analog output can be set using parameter P542 independently of the actual

operating status of the FI. During Bus control this function can supply such things as an analog
value from the control.

8 = Apparent power: the actual apparent power calculated by the FI.
9 = Effective power: the actual effective power calculated by the FI.
10 = Torque [%]: the actual torque calculated by the FI.
11 = Field [%]: the actual field in the motor calculated by the FI.
12 = Current frequency +/-, the analog voltage is proportional to the output frequency of the FI,

whereby the zero point is shifted to 5V. For rotation to the right, values between 5V and 10V are
output, and for rotation to the left values between 5V and 0V.

13 = Speed +/-, is the synchronic rotation speed calculated by the FI, based on the current setpoint,

whereby the zero point has been shifted to 5V. For rotation to the right, values between 5V and
10V are output, and for rotation to the left values between 5V and 0V.
If Servo mode is being used, the measured speed will be output via this function.

14 = Torque [%]+/-, is the actual torque calculated by the FI, whereby the zero point is shifted to 5V.

For drive torques, values between 5V and 10V are output, and for generator torque, values
between 5V and 0V.

30 = Setpoint frequency before ramp, displays the frequency produced by any upstream controllers

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

If the FI is enabled (R or L), the output frequency can be infinitely
varied with a high signal. To save an actual output frequency in
P113, both inputs must be set to a high potential simultaneously

0 ... 1
[ 0 ]

In the standard setting (P428 = 0  Off) the inverter requires a flank for enable (signal change from
"low  high") at the applicable digital input.

In the setting On  1 the FI reacts to a high level.
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)

BUS

-400 ... 400 Hz
[ 0 ]

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 = f

min

, P105 = f

max

) 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.
