Due to their principle of operat
frequency inverters generate leakage currents. For the correct operation of the frequency inverter on a current­sensitive RCD, the use of an all-current sensitive earth leakage circuit breaker (Type B) compliant with EN 50178
/ VDE 0160 is necessary.

Note

The frequency inverters are suitable for operation on TN or TT networks as

Maintenance

In normal use, frequency inverters are maintenance free.
The cooling surfaces must be regularly cleaned with c ompressed air if the ambient air is dusty.
In case of long-term shut-down or long-term storage, the capacitors must be re-formed (refer to "Technical Data").
Failure to do this will damage these components and will cause a considerable reduction of the service life -

2. Assembly and installation

SK 500E frequenc y inverters are available in vari ous si zes depending on the outp ut . At tent io n must 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 possib le 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. 1 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 exceeded. ( 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.

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 matc hing 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 sizes 1 ... 4 the wall mounting brackets can be ins erted 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 lement is covered
with a flat surface and that the device is mounted vertically. This enables
optimum convection, which ensures fault-free operation.

2.2.1 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 installat ion ensures safe and problem-free operatio n. To meet the limitin g 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 cable 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 motor c ontro lle d by the frequency inverter s hou ld b e c on nected 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. Where possible, shielded c ables should b e used for control c ircuits. T he shieldin g at the cable e nd
should be caref ully sealed and it m ust be e nsured th at th e wires are not laid over longer distanc es
without shielding.

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

4. The control cables should be i nstalled as far as possible from power cables, using s eparate cable
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. Shielded or armoured cabl es should b e used f or the load c onnect ions (m otor cable). T he shieldi ng
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.

2.2.3 Electrical connections, power unit

Before connecting the frequency inverter, the following must be observed:

1. Ensure that the mains supply provides the correct voltage and is suitable for the current required.

2. Ensure that suitable circuit br eak ers with t he s pecified nom inal cur ren t range are instal led between
the voltage source and the inverter.

3. Connect the mains voltage directly to the mains terminals L1-L2/N-L3-PE (for each device)

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 motor cables (recom m ended) are us ed, the c able scree 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.

To connect the power unit, the following tools must be used:

2.3 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 signa ls
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 increm ents. This is set with the normal scaling via parameter
P301 "Incremental encoder pulse number" in the menu group "Control parameters". For cable lengths > 20 m and motor s peeds
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 cable, in which the cros s-section
can be increased by connecting several conductors in parallel.

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

Note

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

Incremental encoder

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. By 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
internal voltage (according to the frequency inverter version: 12V /15V /24V).

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 0.

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

RECOMMENDATION: For the correct operation of the drive unit, it is necessary to input the

motor data (rating plate) as precisely as possible. In particular, an
automatic stator resistance measurement using parameter P220 is
recommended.

In order to aut omatically determine the stator res istance, set P220 = 1

and then confirm by pressing "ENTER". The value calculated for the

6. Operating status messages

According to the cause, m otor control lers and technol ogy units gen erate appr opriate m essages if they
deviate from their normal operating status. There is a differentiation between warning and error
messages. If the fr equency inverter is in the status "Start disab led", the reason for this can also be
displayed.

The messages generated for the motor controller are displayed in the corresponding array of
parameter (P700). The message displays for technology units are described in the relevant
supplementary instructions.

Frequency inverter switch-on block

If the frequency inverter is i n the s ta tus "N ot Re ady" or "Start Disabled", t h e reas o n f or this is in dicat ed
in the third array element of parameter (P700).

Display is only possible with the NORD CON software or the ParameterBox.

Warning messages

Warning messages ar e gen erated as soon as a define d lim it is reac he d. Ho w ever this does not cause
the frequency inver ter to switch of f. These mess ages can be displa yed via the arra y element [-02] in
parameter (P700) unti l either the reas on for the warning is no long er present or the fr equenc y inverter
has gone into a fault state with an error message.

Fault messages

Errors cause the frequency inverters to switch off, in order to prevent a device fault.
The following options are available to reset a fault (acknowledge):

• by switching the mains off and on again,

• by an appropriately programmed digital input (P420 = Function 12),

• by switching off the “enable” on the frequency inverter
(if no digital input is programmed for acknowledgement),

• by Bus acknowledgement or

• by P506, the automatic error acknowledgement.

LED displays

The status of the FI is indicted by integrated st atus LEDs, which are visib le from the outside in the
state as delivered. Ac cording to the type of FI, this is a two-c olour LED (DS = Dev iceState) or two
single-colour LEDs (DS DeviceState and DE = DeviceError).

Meaning:

Green indicates readiness and the pr esent of mains voltage. In operation, the

level of overload at the FI outp ut is shown with an increasing ly rapid flashing
code.

Red Signals the presence of an error by flashing according to the number

code of the error. This flashing code (e.g.: E003 = 3 x flashing) indicates the
error groups.

SimpleBox / ControlBox display

The SimpleBox or ControlBox dis plays an error with its num ber and the prefix "E". In addit ion, the
current fault can be displa yed in arra y element [-01] of param eter ( P700). T he last error messages are
stored in parameter P701. Further information on inver ter status at the time that the err or occurs can
be found in parameters P702 to P706 / P799.

If the cause of the error is no longer present, t he error display in the Sim pleBox/ControlBox flashes
and the error can be acknowledged with the Enter key.

In contrast, warning messages are prefixed with "C" ("Cxxx") and cannot be acknowledged. They
disappear automaticall y when the reason for them is no longer pres ent or the frequency inverter has
switched to the "Error" state. Display of the message is suppressed if the warning appears during
parameterisation.

The present warning message can be displayed in detail at any time in array element [-02] of
parameter (P700).

The reason for an existing disabled switch on cannot be displayed with the SimpleBox or the
ControlBox.

8.1 Maintenance Instructions

In normal use, fr equency inverters are maintenance f ree if used cor rectly. Please note the "Gener al
data" in Chap. Fehler! Verweisquelle konnte nicht gefunden werden..

Dusty environments

If the frequency converter is used in a dusty environment, the cooling surfaces should be regularly
cleaned with com pressed air. If air intake filters ha ve been built into the control c abinet, 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 re-commissioned 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
30 min. with 100% mains voltage

Long-term storage for >3 years or if the storage period is not known:

120 min with 25% mains voltage
120 min with 50% mains voltage
120 min with 75% mains voltage
120 min. with 100% mains voltage

The device must not be subject to load during the regeneration process.
After the regeneration pr ocess, the regulations descri bed above apply again (at least 6 0 min on the

mains 1x per year).

24 V control voltage

The 24 V control voltage supply must also be connected for SK 5x5E devices up to size 4.
