Safety and operating instructions for drive power converters

(as per: Low Voltage Directive 73/23/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, initialisation and maintenance work must be carried out by qualified personnel (compliant with IEC 364, CENELEC HD 384, DIN VDE 0100, IEC 664 or 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 89/392/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 (89/336/EEC) is complied with.

The drive power converters meet the requirements of the Low Voltage Directive 73/23/EEC. The harmonised standards in prEN 50178/DIN VDE 0160, in association with EN 60439-1/VDE 0660 Part 500 and EN 60146/VDE 0558 were used for the drive power converter.

Technical data and information for connection conditions can be found on the rating plate and in the documentation, and must be complied with.

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. VBG 4).

The electrical installation must be implemented according to the applicable regulations (e.g. cable cross-section, fuses, ground lead connections). Further instructions can be found in the documentation.

Information about 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 limiting values specified in the EMC regulations is the responsibility of the manufacturer of the system or machine.

6. Operation

Where necessary, systems where drive power converters are installed must be equipped with additional monitoring and protective equipment according to the applicable safety requirements, e.g. legislation concerning technical equipment, accident prevention regulations, etc. Modifications to the drive power converter using the operating software are permitted.

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.

All covers must be kept closed during operation.

7. Maintenance and repairs

The manufacturer documentation must be complied with.

These safety instructions must be kept in a safe place!

1 General information

The NORDAC SK 200E is based on the tried and tested NORD platform. These devices feature a compact design with optimum control characteristics.

These devices are provided with sensorless vector current control which in combination with asynchronous three-phase motor types constantly ensures an optimised voltage-to-frequency ratio. This has the following significance for the drive: Peak start-up and overload torques at constant speed.

This series of devices can be adapted to individual requirements by means of extension modules.

Due to the numerous setting options, these inverters are capable of operating all three-phase motors. The

power range is from 0.25kW to 7.5kW with an integrated mains filter.

This manual is based on the device software V1.7 R1 (see P707) of the SK 200E. 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/).

For the SK 215E/225E/235E there are additional descriptions for functional safety (BU 0230), the integrated AS interface (BU 0200, Section 2.7) and the positioning system (BU 0210). These contain all the necessary additional information for start-up.

If a bus system is used for communication, a corresponding description (BU 0250) is provided, or this can be downloaded from the Internet (

http://www.nord.com/).

A typical feature of this series of devices is their installation directly on a three-phase asynchronous motor. Alternatively, optional accessories are available for installation in the vicinity of the motor, e.g. on a wall or on the frame of the machine.

In the simplest configuration, even without an EEPROM, there is the possibility of setting all important parameters via two potentiometers and eight DIP switches. LEDs are provided for the diagnosis of the operating status. The use of a control module is therefore not absolutely necessary.

In order to gain access to all parameters, the internal RS232 PC interface (RJ12) can be used, or an optional SimpleBox or ParameterBox may be used. In this case, the parameter settings which have been changed by the operator are stored in the plug-in EEPROM. The EEPROM must then always remain plugged in during operation.

AS interface features (SK 225E/235E):

 Electrically isolated bus interface.

 Status indication with LED.

 Slave profile 7.0 with cyclical 4 Bit I/O data.

 Optional M12 connection.

 Up to 4 digital SK 225/235E inputs can be integrated.

 Up to 31 frequency inverters on one bus conductor (A-slave technology)

 Cycle time ≤ 5ms

1.4 Safety and installation information

NORDAC SK 200E frequency inverters are devices 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 with the

device disconnected. The operating instructions must always be available to these persons and must be strictly observed.

 Local regulations for the installation of electrical equipment and 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.

 For single phase operation (115/230V) the mains impedance must be at least 100H for

each conductor. If this is not the case, a mains choke must be installed.

 For safe isolation from the mains, all poles of the supply cable to the frequency inverter

must be able to be disconnected.

 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

electrical isolation from the mains.

 Warning: with certain settings, the frequency inverter/motor can start up automatically

after the mains are switched on.

 The frequency inverter is only intended for permanent connection and may not be

operated without effective earthing connections which comply with the local regulations for large leakage currents (> 3.5mA). VDE 0160 stipulates the installation of a second earthing conductor or an earthing conductor cross-section of at least 10 mm

 Normal FI-circuit breakers are not suitable as the sole protection for three-phase

frequency inverters if the local regulations do not permit a possible DC proportion in the fault current. According to EN 50178 / VDE 0160, the FI circuit breaker must be an allcurrent sensitive FI circuit breaker (type B).

 In normal use, NORDAC 200E frequency inverters are maintenance free. The cooling

surfaces must be regularly cleaned with compressed air if the ambient air is dusty.

CAUTION

The heat sink and all other metal components can heat up to temperatures above 70°C.

When installing, sufficient distance from neighbouring components must be maintained. Allow sufficient cooling time before working on the components.

Protection against accidental contact may need to be provided.

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!

Work may only be carried out by qualified specialist electricians and with the electrical supply to the equipment disconnected!

1 General

BU 0200 GB Subject to technical alterations 13

1.10 Version with protection class IP55 / IP66

NORDAC SK 200E frequency inverters and the additional modules are available in all sizes and in the

protection classes IP55 (standard) or IP66 (optional).

The protection class IP66 must

always be stated when ordering!

There are no restrictions or differences to the scope of functions in either protection class. In order to

differentiate the protection classes, modules with protection class IP66 are given an extra “-C” (coated 

coated PCBs) in their type designation.

e.g. SK 205E-750-340-A-C

IP55 version

The IP55 version of the SK 200E is the standard version. Both versions (motor-mounted, mounted on the

motor or wall-mounted on a wall bracket) are available. In addition, all adapter units, technology units and customer units are available for this version.

IP66 version

In contrast to the IP55 version the IP66 version is a modified option. Both variants (motor-integrated, close to

motor) are also available. The modules available for the IP66 version (adapter units, technology units and customer units) have the same functionalities as the corresponding modules for the IP55 version.

NOTE

The modules for the IP66 design are identified by an additional "-C" and are modified according to the following special measures listed below.

Special measures:

 Impregnated PCBs, painted housing  Diaphragm valve for pressure compensation on temperature changes.  Low pressure test

 A free M12 screw connection is required for low pressure testing. After successful testing, a

diaphragm valve is inserted here. This screw connection is therefore no longer available for a cable gland.

NOTE

For all versions, care must be taken that the cable and the cable gland are carefully matched. This is the only way to ensure permanent compliance with the required protection class.

2 Assembly and installation

2.1 Installation and assembly

NORDAC SK 200E frequency inverters are available in various sizes depending on their output. Connection of the SK 200E to the motor or the wall-mounting unit is made by means of the a suitable size of connection unit SK T14-… The frequency inverter is mounted by means of integrated plug contacts.

The devices require adequate ventilation to protect against overheating. For further details, please refer to Section 7 “Technical Data”.

Motor-mounted version

: Here, the ventilation of the motor is integrated into the cooling concept of the FI. Mounting must therefore always be carried out as shown in the illustration. For permanently low motor speeds and self-ventilated motors, a reduction in power similar to the wall-mounted version must be taken into account.

Wall-mounted version

: In continuous operation (S1), mounting away from the motor causes a reduction in the power of the FI by one power level. This means that relative to the motor, the FU must be selected one power level larger.

NOTE

For further details of the power reduction and the possible ambient temperatures, please refer to the technical data in Section 7.

2.1.1 Mounting the adapter unit

For the supply of a complete drive unit (gear unit + motor + frequency inverter) the SK 200E frequency

inverter and the SK T14-... adapter unit are always completely assembled and tested. The adapter unit can also be ordered separately for subsequent mounting on an existing motor or to replace a different motormounted frequency inverter.

NOTE

However, the IP66 compliant SK 200E must be mounted by NORD as special measures must be implemented. IP66 components retrofitted on site cannot ensure that this protection class is guaranteed.

The “Adapter unit SK T14” includes the following components:

 Cast housing, seal (already glued in) and insulation plate  Power terminal block, corresponding mains connection  Control terminal block, corresponding SK 200E version  Screw kit, for mounting on the motor and the terminal bars  Pre-fabricated cable for motor and PTC connections

Procedures:

1. If necessary, remove the original terminal box from the NORD motor, so that only the base of the

terminal box and the terminal strip remain.

2. Set the bridges for the correct motor circuit and connect the pre-fabricated cables for motor and PTC

connections to the respective connection points on the motor.

3. Mount the cast housing on the terminal box base using the existing screws and seal. Position the cast

housing with the dome facing the A-side of the motor. Check the adaptability for different motor manufacturers.

4. Attach the insulating plate above the terminal strip. Screw on the power terminal bar above this using the

2 M4x8 screws and the plastic washers.

5. Connect the motor cables U, V, W to the power terminal block and the PTC cable TF+, TF- to the control

terminal block 38, 39.

2.1.2 Adapters for Different Motors

The mounting of the terminal box differs for the different motor sizes 63 to 112. Because of this, several mounting components are available.

In order to guarantee the maximum protection class IP55 / IP66 of the entire unit, motor must also have a corresponding protection class.

Mounting of SK 200E S I

The adapter unit can be directly attached to size 80 - 100 NORD motors. An additional adapter plate/spacer with an additional seal is required for the sizes 63-71 and 112.

2.1.3 Installation of the SK 200E

In order to carry out the electrical connection of the SK 200E, this may need to be removed from the connection unit. To do this, remove the 4 fastening screws, so that the frequency inverter can be lifted off vertically.

After the electrical connection of the power cables has been made, the frequency inverter can be replaced. This must be carried out in a vertical direction relative to the connection unit without tilting. The PE cinch plug can be used in order to ensure correct guidance.

In order to achieve the maximum protection class IP55/IP66, care must be taken that all frequency inverter fixing screws are gradually tightened diametrically oppositely, with the torques stated in the table below.

For the cable gland of the connecting cable, appropriate screwed connections for cable crosssection must be used.

Dissipation of heat generated by the inverter occurs by means of convection. This is assisted by the airflow of the motor. Because of this, a reduction in power for unventilated motors or wall-mounted devices must be taken into account (for further details see Section 7, Technical Data).

Heat dissipation must not be hindered by severe contamination.

2.3 Brake resistor (BR)

During dynamic braking (frequency reduction) of a three phase motor, electrical energy is returned to the frequency inverter. In order to avoid an overvoltage switch-off of the frequency inverter, an external brake resistor can be used. With this, the integrated brake chopper (electronic switch) pulses the intermediate circuit voltage (switching wave approx. 420V/720V DC, according to the mains voltage) to the brake resistor. Here the excess energy is converted into heat.

CAUTION

The braking resistance and all other metal components can heat up to temperatures above 70°C.

When mounting, sufficient distance from neighbouring components must be maintained. When working on the components, allow sufficient cooling time beforehand

2.3.1 Internal brake resistor SK BRI4-…

The internal brake resistor can be used if only slight, short braking phases are to be expected.

NOTE

With the use of internal resistors, the DIP switch 8 must be set to “On”. This is important in order to activate a limitation of the peak power of the brake resistor. Otherwise, the brake resistor may be damaged during operation.

Alternatively, a suitable power limit can also be set in P555, P556 and P557. However, this is only effective if DIP 8 is set to the “Off” position.

2.4 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 limiting 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 connected to a common earthing point or earthing bar. It is especially important that all control devices connected to the frequency inverters (e.g. an automation device) are connected to the same earthing point as the inverter itself, using a short cable with large cross-section. Flat conductors (e.g. metal clamps) are preferable, as they have a lower impedance at high frequencies.

(2) The bonding cable of the motor controlled by the frequency inverter should be connected directly to the

earthing terminal of the associated frequency inverter. The presence of a central earthing bar in the control cabinet and the grouping together of all bonding conductors to this bar normally ensures safe operation. (See also Chapter 8.3/8.4 EMC)

(3) 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.

(4) 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.

(5) Ensure that the contactors and brake chokes 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 protectors 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.

(6) Use screened or armoured cable for the load connections (motor cable) and earth the

screening/armour at both ends. The earthing should be made directly to the electrically conducting mounting plate of the control cabinet or the screening angle of the EMC Kit (Section 2.4) or the EMC screw connector of the frequency inverter.

In addition, an EMC-compliant cabling must be ensured. (see also Section 8.3/8.4 EMC)

The safety regulations must be complied with under all circumstances when installing the

frequency inverter!

NOTE

The control cables, line cables and motor cables must be laid separately. In no case should they be laid in the same protective pipes/installation ducts.

The test for high voltage insulations must not be used on cables which are connected to the frequency inverter.

NORDAC SK 200E Manual

2.5 Electrical connection

WARNING

THE DEVICES MUST BE EARTHED.

Safe operation of the devices requires that is installed and commissioned by qualified personnel in compliance with the instructions provided in this Manual.

In particular, the general and regional installation and safety regulations for work on high voltage systems (e.g. VDE) must be complied with as must the regulations concerning correct use of tools and the use of personal protection equipment.

Dangerous voltages can be present at 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 are specified for the correct supply voltage.

In order to access the electrical connections, the SK 200E must be removed from the SK T14 connection unit. Proceed as follows:

1. Switch off the mains supply and if necessary check and observe the waiting period.

2. Loosen the 4 Allen screws (4mm).

3. Carefully lift the FI vertically off the connection unit.

4. The electrical connections and the option slots are now freely accessible. .

To replace the FI, proceed in the opposite sequence:

5. Here, special care must be taken that the PE pins are correctly contacted. These are located diagonally in 2 corners of the FI and the connection unit.

6. The FI can only be placed on the SK T14 in one orientation.

7. Evenly tighten the Allen screws in a cross-wise direction.

2.6 Electrical connection of power unit

All connection terminals are located in the connection unit of the frequency inverter.

One terminal block is provided for the power connections and one for the control connections.

The earthing connections (device earthing) are located on the base in the cast housing of the connection unit.

Before and while the device is connected, the following must be observed:

1. Ensure that the mains supply provides the correct

voltage and is suitable for the current required (see Section. 7 Technical Data).

2. Ensure that suitable circuit breakers with the

specified nominal current range are installed between the voltage source and the inverter.

3. Connect the mains voltage directly to the

terminals L

1-L2

/N-L3 and the earth (according to

the device).

4. To connect the motor, three flexible wires U-V-W

should be used when mounting the motor.

5. For wall-mounting a 4-conductor shielded motor

cable (recommended) to the terminals U-V-W and earth should be used. In this case the cable

shielding should be connected to a large area of the metallic screw connector.

NOTE: when using specific wiring sleeves, the maximum connection cross-section can be reduced.

Screwdriver: Use a 5.5mm slot-head screwdriver to connect the power unit.

NOTE: If synchronous machines or several motors are connected in parallel to a device, the

frequency inverter must be switched over to linear voltage/frequency characteristic curves,  P211 = 0 and P212 = 0.

NOTE: The use of shielded cables is essential in order to maintain the specified radio interference

suppression level. (See also Section 8.2, EMC limit classes )

ATTENTION: This device produces high frequency interference, which may make additional suppression

measures necessary in domestic environments. (Details in Section 8.3/8.4)

3.2.1 SimpleBox, SK CSX-3H

This option is used as a simple parameterisation, display and control tool for the SK 200E frequency inverter.

Features

 4-digit, 7-segment LED display

 Complete parameterisation of the frequency inverter.

 Direct control of a frequency inverter

 Displays the active parameter set during

parameterisation and operation and the operating

value set in P001.

After the SimpleBox has been connected and the mains switched on, horizontal lines appear in the 4-digit 7segment display. This display signals the operational readiness of the frequency inverter.

If a creep frequency value is pre-set in parameter P113, or a minimum frequency or setpoint value is pre-set in P104, the display flashes with this initial value.

If the frequency inverter is enabled, the display changes automatically to the operating value selected in parameter >Selection Display value< P001 (factory setting = current frequency).

The actual parameter set in use is shown by the 2 LEDs next to the display on the left in binary code.

NOTE

The digital frequency setpoint is factory set to 0Hz. To check whether the motor is working, a

frequency setpoint must be entered with the / key or a jog frequency via the respective parameter >Jog frequency< (P113).

Settings should only be implemented by qualified personnel, strictly in accordance with the warning and safety information.

ATTENTION: The motor may start immediately after pressing the START key

3.2 External Control Unit

Functions of the SimpleBox:

Starting the frequency inverter. The frequency inverter is now enabled with the set jog frequency (P113). A preset minimum frequency (P104) may at least be provided. Parameter >Interface< P509 and P510 must = 0.

Stopping the frequency inverter. The output frequency is reduced to the absolute minimum frequency (P505) and the frequency inverter shuts down.

7-segment

LED display

4-digit

4 permanently displayed underscores (_ _ _ _) indicate readiness for operation if there is no setpoint. If these underscores are flashing, the frequency inverter is not ready for operation (switchon lock, e.g. function “safe pulse block”), or there is, or was, an error. This must first be rectified.

When the frequency inverter is ready for operation any initial value (P104/P113 for keyboard operation) is indicated by a flashing display. This frequency is immediately displayed on being enabled.

During operation, the currently set operating value (selection in P001) or an error code (Section 6) is displayed.

During parameterisation, the parameter numbers or the parameter values are shown.

3.5 Technology Unit Overview

External Technology Units enable the expansion of the scope of functions of SK 200E frequency inverters.

Users have access to both communication modules and mains units or an I/O expansion.

Modules with connection terminals or M12 system connectors are available as options.

According to the installation location, modules with protection class IP55 or IP66 are available. These can be installed directly on the SK 200E or independent of the SK 200E with an appropriate wall-mounting kit.

Each SK TU4-… Technology Unit requires an SK T14-TU-… Connection Unit . The SK T14-TU-BUS is available for bus modules or the I/O extension. The mains unit or potentiometer modules require an SK T14TU-NET Connection Unit.

For the bus modules or I/O extension with integrated system bus an RJ12 socket (behind a transparent screw-on cover) is also available. This enables communication with other modules or frequency inverters. With this linkage, all devices can be parameterised with a PC and the NORD CON software.

4 Commissioning, SK 200E

The SK 200E inverter series can be commissioned in various ways:

a) By means of the (internal) DIP switches and the (externally accessible) potentiometer, the SK 200E

can be configured for simple conveyor applications. Various LEDs are provided for diagnostic purposes. In this case, no additional options are required; the FI only needs to be supplied with mains voltage and a 24V control voltage. For control (enable regulator, fixed frequencies, setpoint values), up to 4 digital inputs and 2 potentiometers are available.

In this configuration the plug-in EEPROM is not required.

b) A convenient and comprehensive solution is provided by commissioning with software support.

Here, a PC with an RS232/458 interface or a SimpleBox/ParameterBox may be used. The connection to the SK 200E is made via the RJ12 socket on the top. A suitable cable for connection to a PC is available.

Here, the parameterised data is stored in the plug-in EEPROM. This must therefore always remain plugged in during operation.

c) The motor data for the SK 200E is always pre-set to the standard values of a motor with the same

power as the frequency inverter.

ATTENTION

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.

4.1 Minimal configuration without options

For minimum effort for the commissioning and control, the SK 200E can be operated in its condition as delivered. All that is needed is to provide the FI with mains voltage and a 24V control voltage. This can be provided by the operator of the machine, or an optional module (SK CU4-24V-xxx-B, Section 3.3.6) can be used.

The adjustment of the setpoint values is made via the potentiometer P1, which is integrated in the over of the SK 200E (Section 4.1.2). In addition, the

minimum/maximum frequencies can be adjusted with P2.

Enabling of the regulator is carried out with the switch S1.

The PTC input must be bypassed, if a motor with PTC is not available.

4.2 Factory settings

All frequency inverters supplied by Getriebebau NORD are pre-programmed with the default setting for standard applications with 4 pole standard motors (same voltage and power). For use with motors with other powers or number of poles, the data from the rating plate of the motor must be input into the parameters P201...P207 under the menu item >Motor data< <.

NOTE:

All motor data can be pre-set using the parameter P200. After use of this function has been successful, this parameter is reset to

0 = no change! The data is loaded automatically into

parameters P201...P209 – and can be compared again with the data on the motor rating plate.

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

according to the rating plate as precisely as possible. In particular, an automatic stator resistance measurement using parameter P220 is recommended.

In order to automatically determine the stator resistance, P220 = 1 must be set and confirmed by pressing "OK". The value calculated for the line resistance (dependent upon P207) will be saved in P208.

5 Parameterisation

Every frequency inverter is factory-set for a motor of the same power. All parameters can be adjusted "online". There are four switchable parameter sets available during operation. As delivered, all parameters are visible; however, some can be hidden with parameter P003.

NOTE

As there are dependencies between parameters, it is possible for invalid internal data and operating faults to be generated briefly. Only the inactive or non-critical parameter sets 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:

Menu group No.

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 of fixed frequencies) these are added to the set minimum frequency.

This frequency is undershot when

a) The drive is accelerated from standstill.

P107 Brake reaction time

0 ... 2.50 s

[ 0.00 ]

Electromagnetic brakes have a physically-dependent delayed reaction time when actuated. This can cause a dropping of the load for lifting applications, as the brake only takes over the load after a delay.

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.

NOTE: If a time > 0 is set in P107 or P114, at the moment the FI is switched on, the level

of the excitation current (field current) is checked. If no magnetising current is present, the FI remains in magnetising mode and the motor brake is not released.

In order to achieve a shut-down and an error message (E016) in this case, P539

must be set to 2 or 3.

S P

[ 1 ]

This parameter determines the manner in which the output frequency is reduced after "Blocking" (controller enable

 low).

0 = Voltage block: 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. Immediately switching the FI on again can lead to an error message.

1 = Ramp:

The current output frequency is reduced in proportion to the remaining deceleration

time, from P103/P105.

2 = Ramp with delay:

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 = Immediate 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 >DC braking time< 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 = 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: This function cannot be used as a positioning function. This function should not

be combined with ramp smoothing (P106).

5 = Combined braking: Dependent on the actual link voltage, a high frequency voltage is switched

to the basic frequency (linear characteristic curves only, P211 = 0 and P212 = 0). The deceleration time is retained where possible (P103).

 additional motor warming!

The brake ramp does not follow a linear path, but rather a decreasing

quadratic one.

[ 100 ]

Current setting for the functions of DC current braking (P108 = 3) and combined braking (P108 = 5).

The correct setting value depends on the mechanical load and the required deceleration time. A higher setting brings large loads to a standstill more quickly.

The 100% setting relates to a current value as stored in the >Nominal current< parameter P203.

NOTE: The amount of DC current (0Hz) which the FI can supply is limited. For this value,

please refer to the table in Section 8.5.3, column: 0Hz. In the basic setting this limiting value is about 110%.

Depending on the relationship, actual output frequency to max. frequency (P105), the >Time DC brake on< is shortened.

The time starts running with the removal of the enable and can be interrupted by fresh enabling.

P111 P factor torque limit

S P

25 ... 400 %

[ 100 ]

Directly affects the behaviour of the drive at torque limit. The basic setting of 100% is sufficient for most drive tasks.

If values are too high the drive tends to vibrate as it reaches the torque limit. If values are too low, the programmed torque limit can be exceeded.

P112 Torque current limit

S P

25 ... 400 % / 401

[ 401 ]

With this parameter, a limit value for the torque-generating current can be set. This can prevent mechanical overloading of the drive. It cannot provide any protection against mechanical blockages (movement to stops). A slipping clutch which acts as a safety device must be provided.

The torque current limit can also be set over an infinite range of settings using an analog input. The maximum setpoint (compare adjustment 100%, P403/P408) then corresponds to the value set in P112.

The limit value 20% of torque current cannot be undershot by a smaller analog setpoint (P400/405 = 2) (in servo mode with P300 = 1, not below 10%)!

401 = OFF, means that the torque current limit is switched off! This is also the basic setting for

the FI.

The setting of the jog frequency can be carried out directly via this parameter or, if the FI is enabled via the keyboard, by pressing the OK key. In this case, the actual output frequency is set in parameter P113 and is then available for the next start.

NOTE: Specified setpoints via the control terminals, e.g. jog frequency, fixed frequencies

or analog setpoints, are generally added with the correct sign. The set maximum frequency (P105) cannot be exceeded and the minimum frequency (P104) cannot be undershot.

P114 Brake release time

S P

0 ... 2.50 s

[ 0.00 ]

Electromagnetic brakes have a delayed reaction time during release, 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 release time can be taken into account in parameter P114 (Braking control).

During the adjustable release 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).

P207 Motor circuit

S P

0 ... 1

[***]

0 = Star 1 = Delta

The motor circuit is decisive for stator resistance measurement (P220) and therefore for current vector control.

P208 Stator resistance

S P

0.00 ... 300.00 

[***]

Motor stator resistance resistance of a phase winding with a DC motor.

Has a direct influence on the current control of the FI. Too high a value will lead to a possible overcurrent; too low a value to a motor torque that is too low.

The parameter P220 can be used for simple measurement. Parameter P208 can be used for manual setting or as information about the result of an automatic measurement.

NOTE: For optimum functioning of the current vector control, the stator resistance must be

automatically measured by the FI.

P209 No load current

S P

0.1 ... 300.0 A

[***]

This value is always calculated automatically from the motor data if there is a change in the parameter >cos

< P206 and the parameter >Nominal current< P203.

NOTE: If the value is to be entered directly, then it must be set as the last motor data. This

is the only way to ensure that the value will not be overwritten.

P210 Static boost

S P

0 ... 400 %

[ 100 ]

The static boost affects the current that generates the magnetic field. This is equivalent to the no load current of the respective motor and is therefore load-independent.

The no load current is calculated using the motor data. The factory setting of 100% is sufficient for normal applications.

P211 1 Dynamic boost

S P

0 ... 150 %

[ 100 ]

The dynamic boost affects the torque generating current and is therefore a load-dependent parameter. The factory 100% setting is also sufficient for typical applications.

Too high a value can lead to overcurrent in the FI. Under load therefore, the output voltage will be raised too sharply. Too low a value will lead to insufficient torque.



These settings are dependent on the nominal power of the FI or the selection in parameter P200.

Note: P211 and P212 can be deactivated with the DIP switches, see Section 4.1

P212 1 Slip compensation

S P

0 ... 150 %

[ 100 ]

The slip compensation increases the output frequency, dependent on load, to keep the DC asynchronous motor speed approximately constant.

The factory setting of 100% is optimal when using DC asynchronous motors and correct motor data has been set.

several motors (different loads or outputs) are operated with one FI, the slip compensation

P212 must be set to 0%. This rules out a negative influence. This is equally valid for

synchronous motors that do not have slip due to their design.

P213 ISD control loop gain

S P

25 ... 400 %

[ 100 ]

This parameter influences the control dynamics of the FI current vector control (ISD control). Higher settings make the controller faster, lower settings slower.

Depending on the type of application, this parameter can be altered, e.g. to avoid unstable operation

P214 Lead torque

S P

-200 ... 200 %

[ 0 ]

This function allows a value for the expected torque requirement to be set in the controller. This function can be used in lifting applications for a better load transfer during start-up.

NOTE: Motor torques (with rotation field right) are entered with a positive sign, generator

torques are entered with a negative sign. The reverse applies for the counter clockwise rotation.

P215 Boost precontrol

S P

0 ... 200 %

[ 0 ]

Only with linear characteristic curve (P211 = 0% and P212 = 0%).

For drives that require a high starting torque, this parameter provides an option for switching in an additional current during the start phase. The application time is limited and can be selected at parameter >Time boost precontrol< P216.

All current and torque current limits that may have been set (P112 and P536, P537) are deactivated during the boost lead time.

P216 Time boost precontrol

S P

0.0 ... 10.0 s

[ 0 ]

Only with linear characteristic curve (P211 = 0% and P212 = 0%).

Application time for increased starting current.
