1. General

The SK 500E series is based on the tried and tested NORD platform. These devices feature a
compact design with optimum control characteristics.

These frequency inverters are provided with sensorless vector current control system which in
combination with as ynchronous three-ph ase motor types constan tly ensures an optim ised voltage-to­frequency ratio. For the drive unit, this means very hi gh starting and overload torques with constant
speed.

As standard, the freque ncy inverters are eq uipped with a fixed heat sink, via whic h the power losses
are dissipated to the environment. Altern atively, for sizes 1 - 4 there is the ColdPlate version and for
sizes 1 and 2 there is also an external heat sink version.

This series of frequenc y inverters can be adapte d to indivi dual requirem ents b y means of t he modular
technology units.

Due to the wide range of setting options, these inverters can control all three-phase motors. The
power range is from 0.25 kW to 90.0 kW with integrated mains filter.

This manual is base d on the d evice soft ware as state d in the ver sion list (s ee P707). If the frequenc y
inverter uses a diff erent s oftw are v ers ion, t his may cause differences. If nec es s ary, the curr ent manual
can be downloaded from the Internet (http://www.nord.com/

).

There are additional descriptions for the optional functions "Functional Safety "(BU 0530) and the
"POSICON" positioning system (BU 0510) and the memory programmable "PLC" control units
(BU0550). Supplementary descriptions for the optional bus systems are also available

1.4 Safe ty and installation information

NORD frequency inverter s are equipment for use in industrial high volt age systems and ar e operated
at voltages that could lead to severe injuries or death if they are touched.

The frequency inverter a nd its acc es sor ies must only be used for th e p urpos e w hic h is intended by the
manufacturer. Unauthor ised modifications and the use of spare par ts and additional equipm ent which
has not been purchased from or recommended by the manufacturer of the frequency inverter may
cause fire, electric shock and injury.

All of the associated covers and protective devices must be used.
Installation and other work may only be carried out b y qualified electr icians with strict adherenc e to the

operating instructions. Therefore keep these Operating Instructions at hand, together with all
supplementary instructions for any options which are used, and give them to each user.

Local regulations for the installation of electrical equ ipm ent and accident pre vention m ust be complied

2. Assembly and installation

SK 500E frequenc y inverters are available in vari ous s i zes depending on the output. Attention mus t be
paid to a suitable position when install ing.

The equipment requires sufficient ventilation to protect against overheating. For this the minimum
guideline distances f rom adjacent components above and below the fr equency inverter, which could
obstruct the air flow apply.

Distance from device: Mounting can be immediately next to each other. However, for the use of
brake resistances m ounted belo w t he f reque ncy inverter (not poss ible with … -CP devices), the greater
width must be taken into consid eration, particularly in combination with temperature switches on the
brake resistor!

Installation position: The installation position is nor mally vertical. It m ust be ensured tha t the cooling
ribs on the rear of the frequency inverter are covered with a flat surface to provide good convection.

(above > 100 mm, below > 100 mm)

Warm air must be vented above the device!

Fig. 3 Mounting distances for SK 5xxE

If several inverters are arranged above each other, it must be ensured that the upper air entry
temperature limit is not exceede d. (See also Section 0 ) If this is the case, it is recomm ended that an
"obstacle" (e.g. a cab le duct) is m ounted between the inverters so tha t the direct air f low (rising warm
air) is impeded.

Heat dissipation: If the frequency inverter is insta lled in a control cabinet, adeq uate ventilation mus t
be ensured. The heat dissipati on in operation is appr ox. 5% (according to the si ze and equipment of
the device) of the rated power of the frequency inverter.

2.1 SK 5xxE, standard version

Normally, the frequency inverter is mounted directly on the rear wall of a
control cabinet. For th is, two, or f or sizes 5 to 7, f our m atching wall m ounting
brackets are supplied, which are to be inser ted into the he at sink at the rear
of the device. For size 8 and above, the mounting device is integrated.

Alternatively, for si zes 1 ... 4 the wall mounting brackets can be insert ed at
the side of the cooling el ement in order to minimis e the necessary depth of
the control cabinet.

In general, care m ust be taken that the rear of the cool ing e lem ent is c over ed
with a flat surface and that the device is mounted vertically. This enables
optimum convection, which ensures fault-free operation.

2.2 SK 5xxE…-CP in ColdPlate version

Instead of a cooling element /fan, ColdPlate versions of the frequency inverter have a flat m etal plate
on the rear side which is mounted on an existing mounting plate (e.g. the rear wall of the control
cabinet) so as to pro v ide t h ermal conduction. A liqui d c ooling medium (water, oil) may also be passed
through the mounting surface. In this way, not only is the waste heat from the frequency inverter
dissipated more effectively, but also the waste heat from the inverter is prevented from remaining
inside the control c abinet. In additio n to the optim isation of the p ower reserved a nd the service life of
the inverter, this also causes less thermal load on the inside of the control cabinet.

A further advantage of the ColdPlate version is the reduced installation depth of the device and the
fact that in general, there is no need for a fan on the frequency inverter.

Bottom-mounted brake resistors (SK BR4-…) cannot be mounted directly.

2.3 External heat sink kit

External heat sink technology is an optional supplement for ColdPlate
devices. This is use d if an external cooling system is provided, but no
liquid-cooled m ounting plate is available. A cooling element is mounted
on the ColdPlate device, which passes through an opening in the rear
panel of the control cabinet into the exterior air-cooled environment.
Convection takes place ou tside of the control cabinet, which results in
the same advantages as with ColdPlate technology.

2.5 EMC Kit

For optimum EMC-compliant wiring, the optional EMC Kit must be used. This includes a shield
bracket, two hamm er clips, two fasten ing screws an d a pre-assembled PE cable. T he PE cable mus t
be connected to the appropriate screw on the shielding bracket and to the PE terminal of the
frequency inverter. The connection of further PE connections to the shield bracket is possible with
additional ring cable lugs (SK EMC 2-1 and 2-2).

The EMC Kit provides th e pos sibi li t y of attaching the screening of the motor cable to a larg e s urf ac e of
the frequency inverter (interference source). If necessary, a screened brake resistor cable can be
attached with the second hammer clip.

The screening angle is attached to the two housing screws on the lower edge (below the U-V-W
terminals). The m otor cable screening is earthed to a large area of the s creening angle by means of
the hammer clip.

2.6 Brake resistor (BR)

The heat sink and all other metal components can heat up to temperatures above 70°C.
Touching such components may cause local burns to the affected parts of the body (hands, fingers, etc.).
To prevent such injuries, allow sufficient time for cooling down before starting work - the surface temperature

components during installation, or install protection against contact.

Danger of burns

During dynamic brak ing (frequency reduc tion) of a three-phase motor, electrica l energy is returne d to
the inverter. An external br ake resistor can be used in order to prevent the FI from being shut down
due to overvoltage. W ith this, the int egrated brake c hopper (electr onic s witch) pul ses the interm ediate
circuit voltage (switching wave approx. 420 V/775 V(/825 V) DC, according to the mains voltage)
(115 V, 230 V/400 V(/500 V)) to the brake resistor. Here the excess energy is converted into heat.

For inverter powers up to 7.5 kW (230 V: up to 4.0 kW) a standard bottom-mounted resistor
(SK BR4-..., IP40) ca n be u s ed. T his can additionally be equip ped wit h a n opt io na l temperature switch
(bi-metal, switching po int 1 00 ℃
is enclosed. The resistor and the temperature switch are connected by means of flexible stranded
conductors. Approval: UL, cUL

Note: Brake resistors cannot be directly mounted below …-CP (ColdPlate) devices.

For frequency inverters above 3kW chassis resistors (SK BR2-..., IP20) are also available. These
must be mounted i n the co ntrol c abinet, close to th e fr equenc y invert er. T here is a tem perature switch
on the braking resistor to provide protection against overload. Connection of the resistor and the
temperature switch is by means of screw terminals. Approval: UL, cUL

2.10.1 Wiring guidelines

The frequency inverters have been developed for use in an industrial environment. In this
environment, high le vels of electr omagnet ic interf erence can act on the freque ncy inver ter. In gener al,
correct installation ensures safe and problem-free operatio n. To meet the lim iting values of the EMC
directives, the following instructions should be complied with.

1. Ensure that all equipment in the control cabinet is securely earthed using short earthing cables
which have large cross-sections and are connecte d to a common ear thing point or earth ing bar. It
is especially important that each control unit which is connecte d to the electronic drive technol ogy
(e.g. an automatic de vice) has a short c able with a la rge cross-section, which is connected t o the
same earthing point as the dfrequency inverter itself. Flat cables (e.g. metal stirrups) are
preferable, as they have a lower impedance at high frequencies.

2. The bonding cable of the m otor c ontr o lled by the frequency inverter s hou ld b e connected directly to
the earthing terminal of the associated controller. The presence of a central earthing bar in the
control cabinet and the grouping together of a ll bonding conductors to this bar normally ensures
safe operation.

3. W here poss ible, shield ed cables should be us ed for contr ol circuits . The shie lding at th e cable end
should be caref ully sealed and it m ust be e nsured th at th e wires are not laid over longer distances
without shielding.

The shields of analog setpoint cables should only be earthed on one side on the device.

4. T he control cables sh ould be installe d as far as possible f rom power cables , using separate ca ble
ducts, etc. Where cables cross, an angle of 90° should be ensured as far as possible.

5. 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 o ver-voltage limitation are also
effective. This inter ference suppression is partic ularl y impor tant when the c ontactors are contro lled
by the relay in the frequency inverter.

6. Shi elded or arm oured c ables s hould be use d for the load co nnections (m otor c able). The sh ielding
or armouring mus t be earthed at both ends. If possible, earthing should be made directly to t he
electrically conducting mounting plate of the control cabinet or the screening angle of the EMC Kit.

2.10.3 DC-coupling

Overload of link circuits

It is e
circuits of frequency inverters.

Errors in the link circuit coupling have especially negative effects on the charging circuits in the inverters or on the
life span of the link circuits - including their complete destruction.

In drive engineering, DC-coupling is advisable if m otors act as drivers and generators at the sam e
time in the system. Here, the energ y from the drive which is actin g as a generat or can be fed bac k to
the drive which is acti ng as a motor. T he advantages are lower energy consumption a nd the sparing
use of braking resistor s. In addition, t he e nerg y balance c an be m ade eve n m ore ef ficient with the us e
of a regenerative feed bac k unit or an inp ut/f eedb ac k unit. In general, in cas e of D C coupl in g, wh er ev er

possible, devices w ith the same power should be c onnected together. Further more, only operational
devices (whose link circuits are charged) must be coupled.

1 The link circuits of the individual frequency inverters must be protected with suitable fuses.
2 The frequency inverters only obtain their power supply via the link circuit. Electrical isolation is

carried out via the power circuit breakers which must be provided in the supplies to the devices.

3 CAUTION! Ensure that the coupling is only made after readiness is reported. Otherwise, there

is a danger that all the frequency inverters will be charged by a single one.

4 Ensure that the coupling is disconnected as soon as one of the devices is no longer ready for

operation.

5 For a high availability a braking resistor must be used. If different sizes of frequency inverters

are used, the braking resistor must be connected to the larger of the two frequency inverters.

6 If devices with the same rating (identical type) are coupled, and the same mains impedances

are in effect (identical lengths of cable to the mains rail), the frequency inverters may be
operated without mains chokes. Otherwise a mains choke must be installed in the mains cable
of each frequency inverter.

4. A four-core cable must be used to connect the motor. The cable is connected to the motor
terminals PE-U-V-W.

5. If screened m otor cables (r ecom m ended) are us ed, the cable s cree ning m us t also be con nected to
a large area of the m etallic screening angle of the EMC Kit, however, at least to the electricall y
conducting mounting surface of the control cabinet.

6. Above size 8, the cable lugs which are included in the scope of delivery must be used. After
crimping, these must be insulated with shrink hose.

Note

The use of shielded cables is essential in order to maintain the specified radio interference suppression level.
If certain wire end sleeves are used, the maximum cross-section which can be connected can be reduced.

2.11 Colour and contact assignments for encoders

The incremental encod er connect ion is an inp ut for a type w ith two track s and TTL-compatible signals
for EIA RS 422-c ompliant drivers. The m aximum current consumption of incremental encoders m ust
not exceed 150 mA.

The pulse number per rotation can be between 500 and 8192 increments. This is set with t he normal scaling via parameter
P301 "Incremental encoder pulse number" in the menu group "Control parameters". For cable lengths > 20 m and motor speeds
above 1500 rpm the encoder should not have more than 2048 pulses/revolution.

For longer cable lengths the c able cross-section must be selected large e nough so that the voltage
drop in the cable is not too great. This partic ularly aff ects the supply cab le, in which the cr oss-section
can be increased by connecting several conductors in parallel.

Unlike incremental e ncoders, for sine e ncoders or SIN/COS e ncoders the signals are not in the f orm
of pulses, but rather in the form of sine signals (shifted by 90°).

Note

the rotation direction of the encoder to the motor (possibly reversed), a negative number must be set in parameter
P301.

Note

The voltage difference between tracks A and B can be measured with the aid of parameter P709 [-09] and [-10]. If
the incremental encoder is rotated, the value of both tracks must jump between -0.8V and 0.8V. If the voltage only

According to the resolution (pulse number), incremental encoders generate a defined number of
pulses for each rotat ion of the encod er shaft (Tr ack A / Track A invers e) With this , the precise speed
of the encoder or m otor can be meas ured by the fr equency in verter. B y the use of a second trac k (B /
B inverse) shifted by 90° (¼ period), the direction of rotation can also be determined.

The supply voltage for t he encoder is 10-30V. The voltage sour ce can be an external source or the

4. Commissioning

Once the power su pply has been connected to the frequency inverter, it wil l be operational within a
few moments. In this state, the fr equency inverter can be set to the requirements of the application,
i.e. it can be configured. A c ompletely comprehensive description of all th e parameters is set out in
Section 5.

The connected motor m ay only be started after the parameters specific to the application i n question
have been set by qualified personnel.

DANGER

Danger to life!

The frequency inverter is not equipped with a line main switch and is therefore always live when connected to the
power supply. Live voltages may therefore be connected to a connected motor at standstill.

{ 1 }

0 = Voltage disable: The output signal is switched off immediately. The FI no longer

supplies an output frequency. The motor is only braked by mechanical friction.
Immediately switching the FI on again can lead to an error message.

1 = Ramp down: The current output frequency is reduced in proportion to the remaining

deceleration time, from P103/P105. The DC run-on follows the end of the ramp (if
programmed in P559).

2 = Dela yed ramping: as for 1 "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:

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
current set (P109).
With this type of braking, no energy is returned to the FI; heat loss occurs mainly in the
motor rotor.

4 = Const. brake distance, "Constant brake distance": The brake ramp is delayed in starting

if the equipment is not being driven at the maximum output frequency (P105). This
results in an approximately similar braking distance for different frequencies.

NOTE:

5 = Combi. braking, "Combined braking": Dependent on the actual link voltage (UZW), a

high frequency voltage is switched to the basic frequency (only for linear characteristic
curves, P211 = 0 and P212 = 0). The deceleration time is retained where possible
(P103). à additional motor warming!

6 = Quadratic ramp: The brake ramp does not follow a linear path, but rather a decreasing

quadratic one.

7 = Quad. ramp with delay, "Quadratic ramp with delay": Combination of functions 2 and 6.
8 = Quad. ramp w. braking, "Quadratic combined braking": Combination of functions 5 and 6.
9 = Constant accn., "Constant acceleration power": Only applies in field weakening range!

The drive is accelerated or 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 = Const. accn. delay, "Constant acceleration power with delay": Combination of functions

2 and 9.

12 = Const. accn. mode 3, "Constant acceleration power mode 3": as for 11, however with

additional chopper relief.

13 = Switch off delay, "Ramp with switch-off delay":As for 1 "Ramp", however, before the

brake is applied, the drive unit remains at the absolute minimum frequency set in
parameter (P505) for the time specified in parameter (P110).
Application example: Re-positioning for crane control.

This parameter determines how the FI reacts to an analog signal which is less than the 0 %
adjustment (P402).

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).

1 = 0 - 10V: If a setpoint smaller than the programmed adjustment 0% (P402) is present, this

simple voltage source and potentiometer.

E.g. internal setpoint with rotation direction change: P402 = 5 V, P104 = 0 Hz,
Potentiometer 0-10 V à Rotation direction change at 5 V in mid­potentiometer.

At the moment of reversal (hysteresis = ± P505), the drive
