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 versi on 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 ess ar y, the current 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

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 the f reque ncy inverter (not possib le with … -CP devices), the gre ater width must be taken into consid eration, particularly in combination with temperature switches on the brake resistor!

Installation position: The installatio n positio n is normall y vertical. It must be ensur ed that the coo ling 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 cas e, it is recommended 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, a dequate ventilation m ust 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 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 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 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 SK 5xxE…-CP in ColdPlate version

Instead of a cooling element /fan, ColdPlate versions of the frequency inverter have a flat metal plat e 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 liq ui d c ooling medium (water, o il) 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 cabinet. In addit ion to the optim isation of the p ower reserved and th e 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 d epth 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.

Alternatively, the EMC Kit can be simply used as a strain relief (e.g. for the connection cables of a bus system)

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-assem bled PE cable. T he PE cable m ust 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 lar g e sur f 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.

CAUTION

Danger of burns

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.

During dynamic brak ing (frequency reduc tion) of a three-phase motor, electrica l energy is retur ned to the inverter. An external br ake resistor can be used in order to prevent the F I 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. This can additionally be equipped with an 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, cU L

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 cont rol c abinet, close to th e fr equenc y invert er. T here is a tem per ature switch on the braking resistor to provide protection against overload. Connection of the resistor and the temperature switch is by means of screw terminals.

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 pro blem-free operation. T o meet the limiting v alues 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 lar ge 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 contr o lle d by the frequency inverter s hou ld be c on nec ted d irec tly 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.

In drive engineering, DC-coupling is advisable if m otors act as drivers and generators at the same time in the system. Here, the energ y from the drive which is acting as a generator can be fed back to the drive which is acti ng as a motor. T he advantages are lo wer energy consumptio n and 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 back unit or an input/feedbac k unit. In general, in c ase of D C c oupl in g, wh er ever

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.

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. Ens ure that sui table circuit br eak ers with t he s pecified nom inal cur rent range are instal led be tween 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 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.

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 must 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 m otor speeds above 1500 rpm the encoder should not have more than 2048 pulses/revolution.

The counting direction of the incremental encoder must correspond to that of the motor. Therefore, depending on jumps between 0 and 0.8V the relevant rack is faulty. The position can no longer be determined via the

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°).

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. B y the use of a second track (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).

Hiperface encoder

Hiperface is a mixtur e of incremental encoder an d absolute enco der and combine s the advantages of both encoder types. The absolute va lue is initially only formed when the device i s switched on and is communicated by the RS485 specification bus parameter interface to the external counter in the controller, which then continues counting incrementally from this absolute value using the analog sine/cosine signal. Dur ing oper atio n the co unted p osition is conti nuous l y compar ed with th e m easured absolute position of the encoder.

Hiperface encoders are suitable for positioning in combination with servo mode. The requirements for the analog signal are shown in the following table. It must be noted that the

tolerances in the voltages affect the precision of the determined position. The supply voltage f or the encoder is 7-12V. An external source or the int ernal 12V voltage can be

used as the voltage supply.

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

2 = Delayed ramping: as for 1 "Ramp", however for generational operation the brake ramp

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.

SK 54xE – Users Manual for Frequency Inverters

Voltage controlled: With the first start of the machine, a voltage indicator is memorised which ensures that the rotor of the machine is set to the rotor position "zero". This typ starting position of the rotor can only be used if there is no counter-torque from the machine (e.g. flywheel drive) at frequency "zero". If this condition is fulfilled, this method of determining the position of the rotor is very precise (<1° electrical). In principle, this method is not suitable for lifting equipment, as there is always a counter

For operation without encoders (in preparation), the following applies: Up to the switch over

frequency P331 the motor (with the nominal current memorised) is driven under voltage control. Once the switch over frequency has been reached, the method of determining the rotor position is switched over to the EMF method. If, taking hysteresis (P332) into account, the frequency falls below the value in (P331), the frequency inverter switches back from the EMF method to voltage controlled operation.

Test signal method: The starting position of the rotor is determined with a test signal. This method also functions at a standstill with the brake applied, however it requires a PMSM with sufficient anisotropy between the inductivity of the d and q axes. The higher this anisotropy is, the greater the precision of the method. By means of parameter (P212) the voltage level of the test signal can be adjusted and with parameter (P213) the position of the motor position control can be adjusted. For motors which are suitable for use with the test signal method, a rotor position accuracy of 5°…10° electrical can be achieved (depending on the motor and the anisotropy

For operation without encoders (in preparation), the following applies: Until the switchover

frequency is reached, the rotor position is determined by means of the test signal method. After this, with the setting "0" it is switched over to the EMF metho

Value from universal encoder,

With this method the starting position of the rotor is determined from the absolute position of a universal encoder (Hiperface, EnDat with Sin/Cos track, BISS with Sin/Cos track or SSI with Sin/Cos track) The universal encoder type is set in parameter (P604). For this position information to be unique it must be known (or determined) how this rotor position relates to the absolute position of the universal encoder. This is performed via offset parameter (P334). Motors should be delivered either with a starting rotor position "zero" or the starting rotor position must be marked on the motor.If this value is not available, the offset value can also be determined with the settings "0" and"1" of parameter (P330). For this the drive unit is started with the setting "0" or "1". After the first start the offset value which has been determined is saved in parameter (P334).However, this value is volatile, i.e. it is only saved in the RAM. In order to save it in the EEPROM, it must be briefly changed and then set back to the determined value. After this, fine tuning can be carried out with the motor idling. For this, the drive is operated in closed loop mode (P300=1) at as high a speed as possible below the field weakening point. From the starting point, the offset is gradually adjusted so that the value of the voltage component U

(P723) is as close to zero as possible. For this, a balance between the positive and negative direction of rotati Usually the value "zero" will not be completely achieved, as at higher speeds the drive is subjected to a slight load due to the motor fan. The universal encoder should be located on the motor shaft.

Value from CANopen encoder,

As for "2", however a

CANopen absolute encoder is used to determine the starting position of the rotor.

If there is an incremental encoder with a "null track" on the motor shaft, the "null track" can also be used to determine the position of the stator. The zero impulse is then used for synchronisation of the rotor position.

The offset between the zero pulse and the actual "zero" rotor position is set in parameter (P334) "Encoder offset". If the Sense cable (+5V Sense and 0V Sense) is not connected, there is no synchronisation to the zero pulse. Parameter (P330) must be set to "0" or "1". The value which needs to be set for parameter (P334) must be determined experimentally or must be enclosed with the motor.
