Safety and operating instructions

for the drive power converter

(as per: Low voltage guideline 73/23/EEC )

1. General information

During operation, drive power converters may have, depending on their protection class, live, bare, moving or rotating parts or hot surfaces.

Unauthorised removal of covers, improper use, incorrect installation or operation leads to the risk of serious personal injury or material damage.

Further information can be found in this documentation.

All transportation, installation and initialisation and maintenance work must be carried out by qualified personnel (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 erection, installation, commissioning and operation of this product and who have the relevant qualifications for their work.

2. Intended use

Drive power converters are components intended for installation in electrical systems or machines.

1 General information

The series NORDAC SK 700E is the follow-on development of the proven vector series. These devices are characterised by the high modularity and excellent control characteristics.

These devices are provided with non-sensor vector current control system which constantly ensures an optimised voltage-tofrequency ratio in combination with a motor model of an three-phase asynchronous motor. This has the following significance for the drive: Peak start-up and overload torques at constant speed.

Due to its modular construction, the variously combinable technology units, customer units and special extension units, this device series is suitable for all possible applications.

Devices for constant load:

Due to the numerous setting options, these inverters are capable of controlling all three-phase motors. The performance range goes from 1.5kW to 22kW (3~ 380V...480V) with an integrated line filter and from 30kW to 132kW (3~ 380V...480V) with optional external line filter. The overload capacity of these devices is 200% for 3.5 seconds and 150% for 60 seconds.

Device for quadratically increasing loads SK 700E-163-340-O-VT

In the performance range 160kW (3~ 380V...480V) a variant for quadratically increasing load is available. This load profile is typical for fans and various pump applications. In contrast to the devices used for constant load torque, the overload capacity here is limited to 125%.

NOTE

: The SK 700E with the performance range 30kW to 160kW varies in some technical details from the lower

performance devices. Details can be found in this manual.

This manual is based on the device software V3.3 Rev0 (P707) for the SK 700E. If the frequency inverter used has a different version, this may lead to some differences. If necessary, you can download the current manual from the Internet (http://www.nord.com/)

1.4 Safety and installation information

NORDAC SK 700E frequency inverters are equipment for use in industrial high voltage systems and are operated at voltages that could lead to severe injuries or death if they are touched.

• Installation and other work may only be carried out by qualified electricians and when the device is

disconnected. The manual must always be available for these persons and must be complied with.

• Local regulations for the installation of electrical equipment as well as for accident prevention must be

complied with.

• The equipment continues to carry hazardous voltages for up to 5 minutes

after being switched off at the mains. The equipment may only be opened or the cover or control element removed 5 minutes after the equipment has been disconnected from the power supply. All covers must be put back in place

before the line

voltage is switched back on again.

• Even during motor standstill (e.g. caused by a release block, blocked drive or output terminal short circuit), the

line connection terminals, motor terminals and braking resistor terminals may still conduct hazardous voltages. A motor standstill is not

identical to galvanic isolation from the mains.

• Attention, even parts of the control card and, in particular, the connection plug for the removable technology

units can conduct hazardous voltages. The control terminals are mains voltage free.

• Warning, under certain settings the frequency inverter can start automatically after the mains are switched on.

• The circuit boards contain highly-sensitive MOS semiconductor components that are particularly sensitive to

static electricity. Avoid touching circuit tracks and components with the hand or metallic objects. Only the terminal strip screws may be touched with insulated screwdrivers when connecting the cables.

• The frequency inverter is only intended for permanent connection and may not be operated without effective

earthing connections that comply with local regulations for large leak currents (> 3.5mA). VDE 0160 requires the installation of a second earthing conductor or an earthing conductor cross-section of at least 10 mm

• Normal FI-circuit breakers are not suitable as the sole protection in three-phase frequency inverters when

local regulations do not permit a possible DC proportion in the fault current. The standard FI circuit breaker must comply with the new design as per VDE 0664.

• The inverter must be mounted in a switch cabinet that is suitable for its immediate surroundings. In particular it

must be protected from excess humidity, corrosive gases and dirt.

• In normal use, NORDAC SK 700E frequency inverters are maintenance free. The cooling surfaces must be

regularly cleaned with compressed air if the ambient air is dusty.

ATTENTION! DANGER TO LIFE!

The power unit can continue to carry voltages for up to 5 minutes after being switched off at the mains.

Inverter terminals, motor cables and motor terminals may carry voltage!

Touching open or free terminals, cables and equipment components can lead to severe injury or death!

2 Assembly and installation

2.1 Installation

NORDAC SK 700E frequency inverters are available in various sizes depending on the output. When installed in a control cabinet, the size, power dissipation and perm. ambient temperature must be taken into account to prevent device failures.

The equipment requires sufficient ventilation to protect against overheating. Reference values apply here for the spaces above and below the frequency inverter within the control cabinet.

(up to and inc. 22kW, above > 100mm, below > 100mm and from and inc. 30kW above > 200mm, below > 200mm)

Electrical components (e.g. cable ducts, contactors, etc.) can be located within these limits. There is a height-dependent minimum separation distance from the frequency inverter for these components. This distance must be a minimum 2/3 of the object height. (Example: cable duct 60mm high Æ2/3⋅ 60mm = 40mm gap)

Additional side gaps for devices up to and inc. 55kW are not required. Mounting can be immediately next to each other. The

installation position is normally vertical

. It must be ensured that the cooling ribs on the rear of the device are covered with a flat

surface to provide good convection.

Warm air must be vented above the device!

If several inverters are arranged above each other, ensure that the upper air entry temperature limit is not exceeded. (See also Chapter 7, Technical data). If this is the case, it is recommended that an "obstacle" (e.g. a cable duct) is mounted between the inverters so that the direct air flow (rising warm air) is impeded.

2.5 Line choke (accessories)

To reduce input side current harmonics, additional inductivity can be installed into the line supply to the inverter.

These chokes are specified for a maximum supply voltage of 480V at 50/60 Hz.

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

For frequency inverters with an output of 45 kW or more, a line choke is recommended where several devices are being used, in order to avoid possible adverse effects of one device on another. In addition, the charging currents (mains voltage fluctuations) are significantly reduced.

2.6 Output choke (accessories)

To reduce interference signals from the motor cable or to compensate for cable capacitance in long motor cables, an additional output choke can be installed into the inverter output.

Take care during installation that the pulse frequency of the frequency inverter is set to 3-6kHz (P504 = 3-6).

These chokes are specified for a maximum supply voltage of 460V at 0-100 Hz.

An output choke should be fitted for cable lengths over 150m/50m (unshielded/shielded). Further details can be found in Chapter 2.10.4 "Motor cable".

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

2.7 UB brake resistors (accessory)

During dynamic braking (frequency reduction) of a three phase motor, electrical energy is returned to the frequency inverter. In order to avoid overcurrent cut-off of the frequency inverter, the integrated brake chopper can convert the returned energy into heat by connecting an external brake resistor.

For inverter outputs up to 7.5 kW, a standard substructure resistor can be fitted; it can also be optionally equipped with a heat monitor for additional thermal protection of the resistor.

This design is no longer possible with higher frequency inverter outputs. Instead, the chassis brake resistors (Chapter 2.8) can be used.

2.8 Chassis brake resistors (accessory)

During dynamic braking (frequency reduction) of a three phase motor, electrical energy is released and returned to the frequency inverter. To prevent a safety shut-down of the frequency inverter, the integrated brake chopper can be activated by the connection of an external brake resistor.

The returned energy is converted into heat, so avoiding a possible overvoltage.

All chassis resistors are UL certified and are not subject to restrictions in the North American market.

Connection is with screw connectors that are designated +B, B (1.5-22kW) or BR, +ZW (30-160kW), and the safety leads.

For overload protection, a thermal switch is located close to a brake resistor. The switch is freely available via the screw connectors (2 x 4mm

). The switching capacity is

limited to 250VAC/10A, 125VAC/15A and 30VDC/5A.

2.9 Wiring guidelines

The frequency inverter has been developed for use in an industrial environment. In this environment, high levels of electromagnetic interference can influence the frequency inverter. In general, correct installation ensures safe and problem-free operation. To meet the limit values of the EMC directives , the following instructions should be complied with.

(1) Ensure that all equipment in the cabinet is securely earthed using short earthing cables that have large cross-sections and

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

The PE lead of the motor controlled by the frequency inverter must be connected as directly as possible to the earth connection of the cooling element, together with the PE of the corresponding frequency inverter mains supply. The presence of a central earthing bar in the control cabinet and the grouping together of all PE conductors to this bar normally ensures safe operation. (See also Chapter 8.3/8.4 EMC guidelines)

(2) Where possible, shielded cables should be used for control loops. The shielding at the cable end should be carefully sealed

and it must be ensured that the wires are not laid over longer distances without shielding.

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

(3) The control cables should be installed as far as possible from power cables, using separate cable ducts, etc. Where cables

cross, an angle of 90° should be ensured as far as possible.

(4) Ensure that the contactors in the cabinet are interference protected, either by RC circuits in the case of AC contactors or by

free-wheeling diodes for DC contactors, for which the interference traps must b e positioned on the contactor coils. Varistors for over-voltage limitation are also effective. This interference suppression is particularly important when the contactors are controlled by the relay in the frequency inverter.

(5) Shielded or protected cables should be used for load connections and the shielding/protection should be earthed at both

ends, if possible directly to the frequency inverter PE/shield angle.

(6) If the drive is to be used in an area sensitive to electromagnetic interference, then the use of noise suppression filters is

recommended to limit the cable-dependent and radiated interference from the inverter. In this case, the filter must be mounted as closely as possible to the frequency inverter and fully earthed.

It is also an advantage if the inverter is installed together with the line filter in an EMC-pr oof enclosure, with EMC-compliant cabling. (See also Chapter 8.3/8.4 EMC)

(7) Select the lowest possible switching frequency. This will reduce the intensity of the electromagnetic interference produced by

the frequency inverter.

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

frequency inverter!

Note

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

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

2.10 Electrical connections

2.10.1 Line and motor connections

WARNING

THESE DEVICES MUST BE EARTHED.

Safe operation of the devices presupposes that qualified personnel mount and operate it in compliance with the instructions provided in these operating instructions.

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

Dangerous voltages can be present at the line input and the motor connection terminals even when the inverter is switched off. Always use insulated screwdrivers on these terminal fields.

Ensure that the input voltage source is not live before setting up or changing connections to the unit. Make sure that the inverter and motor have the correct supply voltage set.

Note: If synchronising devices are connected or several motors are switched in parallel, the frequency inverter must be

operated with linear voltage/frequency characteristic curves, P211 = 0 and P212 = 0.

The line, motor, brake resistor and control connections are located on the base of the device. To gain access to the terminals, the device covers (cover and grid) must be removed. The connection terminals are now accessible from the front. All covers must be put back in place before switching on the supply voltage!

In general, the line, motor and brake resistor cables are connected first as their terminals are located on the bottom circuit board. The cable inlet is a slit opening on the base of the device.

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

Pay attention to the following:

1. Ensure that the voltage source provides the correct voltage and is suitable for the current required (see Chapter 7 Technical data). Ensure that suitable circuit breakers with the nominal current range are inserted between the voltage source and the inverter.

2. Connect the line voltage directly to the line terminals L

- L2 - L3 and the earth (PE).

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

4. If shielded cables are used, then the cable shield can also be applied to as much surface as possible on the shield support angle.

Note

: The use of shielded cables is essential in order to maintain the specified radio interference suppression level. (See

also Chapter 8.4 EMC limit value classes)

3.1.7 Profibus 24V module (SK TU1-PBR-24V)

Profibus allows numerous different automation devices to exchange data. PLC's, PC's, operating and monitoring devices can all communicate via a uniform bus in serial bit mode. This Profibus option is supplied via an external 24V DC ±25% connection with voltage.

The Profibus subscriber can therefore be identified by the master system even without a power supply to the frequency inverter. The data required for this (PPO type and Profibus address) are provided via a rotary coding switch.

The termination resistor for the last bus participant is located in the Profibus standard plug.

Note

: The settings made using the rotary coding switch are not transferred to the frequency inverter. Detailed information

3.1.10 InterBus module (SK TU1-IBS)

With InterBus up to 256 participants with different automation devices can exchange data. PLC's, PC's, operating and monitoring devices can all communicate via a uniform bus in serial bit mode.

NORDAC frequency inverters are remote bus participants. The data width is variable (3 words; 5 words), at a baud rate of 500kBit/s (optional 2Mbit/s). An additional termination resistor is not necessary as it is already integrated. Addressing is carried out automatically by means of the physical arrangement of the participants.

An external 24V supply is required for uninterrupted Bus operation. Detailed information can be found in the operating instructions BU 0070, or contact the supplier

of the frequency inverter.

3.1.11 AS interface (SK TU1-AS1)

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

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

The SK 700 E supports the AS interface technology unit from software version 3.1 Rev. 1 (P707 / P742).

Motor temperature protection - applies to all customer units! -

For secure protection against motor overheating, a temperature sensor (PTC thermistor (PTC, PTC) can be connected to any digital input (excluding multi-I/O).

The appropriate parameters (P420 ... P423 or P425, depending on option) must be set to a value of 13 (PTC thermistor input) for this purpose.

NOTE

: With multi I/O only digital input 6 (P425) is possible!

The supply voltage varies dependent upon the customer unit. The lowest voltage possible should be chosen.

Internal switching in the inverter prevents excessive PTC voltage.

The cable routing should always be separate from the motor cable and with shielded cables.

3.2.5 BUS customer units

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

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

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

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

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

Note

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

the Bus systems, Profibus ⇒ BU 0020 DE, CANnord ⇒ BU 0060 DE, USS ⇒ BU 0050 DE

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

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

3.3 Special extension units

(EXtension Unit, Option)

Special extension units are very similar to the customer units; they are however designed for other functions and can only be placed in the lower slots. After insertion, they are automatically identified by the frequency inverter.

Cable connection is via direct plug-in clip connectors with spring terminals. This makes the

connection of devices very easy and convenient.

NOTE: If there are deviations from the standard equipment (Type 5820.0H40, 10-30V encoder, TTL/RS422)

for the motors, please note the accompanying data sheet or consult your supplier.

RECOMMENDATION: For greater operating safety, in particular with long connection cables, we recommend the use of a

higher power supply (15V/24V) and an incremental encoder for 10-30V power supply. The signal level must remain at 5V TTL.

ATTENTION: The rotation field of the incremental encoder must correspond to that of the motor. Therefore,

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

General information

Once the power supply has been connected to the frequency inverter, it will be operational after a few moments. In this condition, the frequency inverter can be set up for the application requirements, i.e. parameterised. A complete and comprehensive description of each parameter is set out in the following sections. The motor should only be started with the enable signal after the parameters have been successfully set by qualified personnel.

ATTENTION: The frequency inverter is not equipped with a line main switch and is therefore always live when connected to

the power supply.

4.1 Basic settings

All frequency inverters supplied by Getriebebau NORD are pre-programmed with the factory setting for standard applications with 4-pole standard motors. For use with other motors, the data from the rating plate of the motor must be input into the parameters under the menu item >Motor data<.

Recommendation: It is necessary to input the most precise motor data (rating plate) possible for the correct use of the drive

unit. In particular, an automatic stator resistance measurement (P208) should be carried out.

7 = 1,50 kW ....

230/400 V Δ/Y

Note: In this example, the motor must be "star" wired (400V, P207 = 0).

The frequency inverter is pre-programmed at the factory for standard applications using 4-pole DC standard motors. If another NORD motor is to be used, it can be selected from a motor list in P200. The data is automatically loaded into parameters P201 – P208 and can be compared again with the data from the motor rating plate.

When using other motors, the data from the rating plate of the motor must be input into parameters P201 to P208.

In order to automatically determine the stator resistance, set P208 = 0 and confirm by pressing "ENTER". The value adjusted to the line resistance will be saved (dependent upon P207).

The motor shaft starts up and indicates that the inverter output frequency is

reaching the setpoint of 35Hz.

Note

The desired value is reached after 1.4 seconds (35Hz / 50Hz x 2s). The standard start-up time is 2 seconds to reach 50Hz (as defined by P102 and P105).

The motor speed (i.e. the frequency) can be adjusted directly using the

11. Switch off the frequency inverter using the key.

The motor is braked and is brought to a controlled stop (this takes 1.4 seconds).

The standard deceleration time is 2 seconds from 50Hz to standstill (defined by P103, P105).

Note

The inverter always supplies 0Hz for 0.5 seconds after stopping (P559, >DCTime lag<). If there is a new enable during this period, then this is interrupted.

5 Parameterisation

There are four switchable parameter sets available during operation. All parameters are always visible. All parameters can be adjusted "online".

Note: As there are dependencies between the parameters, it is possible for invalid internal data and operating faults to be

generated temporarily. Only the inactive parameters should be adjusted during operation.

The individual parameters are combined in various parameter sets. The first digit of the parameter number indicates the assignment to a menu group:

The following main functions are assigned to the menu groups:

Menu group No. Master function

Operating displays (P0--):

For the selection of the physical units of the display value.

Basic parameters (P1--):

Contain the basic inverter settings, e.g. switch on and switch off procedures and, along with the motor data, are sufficient for standard applications.

Motor / characteristic curve parameters (P2--):

Settings for the motor-specific data, important for ISD current control, and selection of characteristic curve during the setting of dynamic and static boost.

Control parameters (P3--):

(only with the special extension units: PosiCon or Encoder)

Settings for the control parameters (current controller, speed controller, etc.) with speed feedback.

Control terminals (P4--):

Scaling of the analog inputs and outputs, determining the function of the digital inputs and relay outputs, as well as control parameters.

Additional parameters (P5--):

Functions dealing with e.g. the interface, pulse frequency or error acknowledgement.

Positioning parameters (P6--):

(only with the special extension unit: PosiCon)

Positioning parameters for the PosiCon option Æ see BU 0710!

Information (P7--):

Display of e.g. actual operating values, old error messages, device status reports or software version.

P5--, P6-- and P7-- parameters

Some parameters in these groups can be programmed and read in several levels (arrays).

Note: Parameter P523 can be used to load the factory settings for all parameters at any time. This can be helpful,

e.g. during the commissioning of a frequency inverter whose parameters no longer correspond with the factory settings.

Attention: All parameter settings will be lost, if P523= 1 is set and confirmed with "ENTER".

To safeguard the actual parameter settings, these can be transferred to the ControlBox or ParameterBox memories.

P102 (P) Acceleration time

always visible

0 ... 320.00 s

[ 2.00 ]

> 11kW [ 3.00 ]

> 22kW [ 5.00 ]

Acceleration time is the time corresponding to the linear frequency rise from 0Hz to the set maximum frequency (P105). If an actual setpoint of <100% is being used, the acceleration time is reduced linearly according to the setpoint set.

The start-up time can be extended by certain circumstances, e.g. FI overload, setpoint lag, rounding or if the current limit is reached.

always visible

0 ... 320.00 s

[ 2.00 ]

> 22kW [ 5.00 ]

Deceleration time is the time corresponding to the linear frequency reduction from the set maximum frequency to 0Hz (P105). If an actual setpoint <100% is being used, the deceleration time reduces accordingly.

The deceleration time can be extended by certain circumstances, e.g. by the selected >Switch-off mode< (P108) or >Ramp smoothing< (P106).

P104 (P) Minimum frequency

always visible

0.0 ... 400.0 Hz

[ 0.0 ]

The minimum frequency is the frequency supplied by the FI as soon as it is enabled and no additional setpoint is set.

In combination with other setpoints (e.g. analog setpoint or fixed frequencies) these are added to the set minimum frequency.

This frequency is undershot when

a) the drive is accelerated from standstill.

b) The FI is blocked. The frequency then reduces to the absolute minimum (P505) before it is

blocked.

c) The FI is reversing. The reverse in the rotation field takes place at the absolute minimum

frequency (P505).

This frequency can be continuously undershot if, during acceleration or deceleration, the function "Maintain frequency" (Function Digital input = 9) is executed.

P107 (P) Brake reaction time

always visible

0 ... 2.50 s

[ 0.00 ]

Electromagnetic brakes have a physically-dependent delayed reaction time when actuated. This can lead to load drops during lifting applications, as the brake delays in taking over the load.

This reaction time can be taken into account under parameter P107 (Braking control).

Within the adjustable application time, the FI supplies the set absolute minimum frequency (P505) and so prevents movement against the brake and load drop when stopping.

See also the parameter >Release time< P114 Note: For the control of electromagnetic braking (especially for lifting operations) an internal relay

should be used, Æ Function 1, external brake (P434/441). The minimum absolute frequency (P505) should never be less than 2.0Hz.

Available in Option

P108 (P) Disconnection mode

always visible

0 ... 12 [ 1 ]

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

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

output frequency. In this case, the motor is braked only by mechanical friction. Immediate switching on again of the FI can lead to error switch off.

1 = Ramp down: The actual output frequency is reduced proportionally to the remaining braking time

from P103.

2 = Delayed ramping: as with ramp, however for generational operation the brake ramp is extended,

or for static operation the output frequency is increased. Under certain conditions, this function can prevent overload switch off or reduce brake resistance power dissipation.

Note: This function must not be programmed if defined deceleration is required, e.g. with lifting

mechanisms.

3 = Instant DC braking: The FI switches immediately to the preselected DC current (P109). This DC

current is supplied for the remaining proportion of the >DC brake time< (P110). Depending on the relationship, actual output frequency to max. frequency (P105), the >Time DC brake on< is shortened. The time taken for the motor to stop depends on the application. The time taken to stop depends on the mass inertia of the load and the DC set (P109). With this type of braking, no energy is returned to the FI; heat loss occurs mainly in the motor rotor.

4 = Constant brake distance: The brake ramp is delayed in starting if the equipment is not

being

driven at the maximum output frequency (P105). This leads to a similar braking distance from various frequencies. Note: This function cannot be used as a positioning function. This function should not be used with a ramp rounding (P106).

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

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

6 = Quadratic ramp: The braking ramp does not have a linear course, but is square. 7 = Quadratic ramp with delay: Combination of functions 2 and 6 8 = Quadratic combined braking: Combination of functions 5 and 6 9 = Constant acceleration power: Only applies in field weakening range! The drive is accelerated

and braked using constant electrical power. The course of the ramps depends on the load.

10 = Distance calculator: Constant distance between actual frequency / speed and the set minimum

output frequency (P104). 11 = Constant acceleration power with delay: Combination of functions 2 and 9. 12 = Constant acceleration power with delay (as 11) with additional ch opper relief

P109 (P) DC brake current

always visible

0 ... 250 %

[ 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.

A setting of 100% corresponds to a current value as set in parameter P203.

P110 (P) Time DC-brake on

always visible

0.00 ... 60.00 s

[ 2.0 ]

The time during which the motor has the current selected in parameter >DC brake current< applied to it during the DC braking functions (P108 = 3).

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) P -factor torque limit

always visible

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 (P) Torque current limit

always visible

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) (with P300 = 1, not below 10%)!

401% = OFF is for switching the torque current limit off! This is also the basic setting for the FI.

P113 (P) Jog frequency

-400.0 ... 400.0 Hz

[ 0.0 ]

When using the ControlBox or ParameterBox to control the FI, the jog frequency is the starting value following successful enable.

Alternatively, when control is via the control terminals, the jog frequency can be activated via one of the digital inputs.

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

Note: Specified setpoints via the control terminals, e.g. jog frequency, fixed frequencies or analog

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 (P) Brake delay off

always visible

0 ... 2.50 s

[ 0.00 ]

Electromagnetic brakes have a delayed reaction time during ventilation, which depends on physical factors. This can lead to the motor running while the brake is still applied, which will cause the inverter to switch off with an overcurrent report.

This ventilation time can be taken into account in parameter P114 (Braking control).

During the adjustable ventilation time, the FI supplies the set absolute minimum frequency (P505) thus preventing movement against the brake.

See also the parameter >Brake reaction time< P107 (setting example). Note: If the brake ventilation time is set to "0", then P107 is the brake ventilation and reaction

time.

This requires the following data to be set: 50.0Hz / 1500 rpm / 15.00A / 400V / cos ϕ=0.90 / Stator resistance 0.01Ω In this setting, the inverter operates without current control, slip compensation and pre-magnetising time, and is therefore not recommended for motor applications. Possible applications are induction furnaces or other applications with coils and transformers.

Motor stator resistance ⇒ line resistance 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.

For simple measurement, this parameter can be set to "Zero". Pressing the ENTER key initiates the automatic measurement between two motor phases. In the FI, the resistance on the line is measured on the basis of the delta or star circuit (P207) and the value saved.

Note: For correct function of the current vector control, the stator resistance must be

automatically measured by the FI.

The motor must not be disconnected from the FI during the measurement!

P209 (P) No load current

This value is always calculated automatically from the motor data if there is a change in the parameter >cos ϕ< 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 (P) Static boost

always visible

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 (P)

Dynamic boost always visible

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, the output current is raised too much. Too low a value will lead to insufficient torque.

P212 (P) Slip compensation

always visible

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.

If several motors (different loads or outputs) are operated with one FI, the slip compensation P212 must be set to 0%. This excludes any negative influences. This is equally valid for synchronous motors that do not have slip due to their design.

P213 (P) ISD control loop gain

P217 Oscillation damping

always visible

10 ... 400 %

[ 10 ]

With the oscillation damping, idling current harmonics can be damped. Parameter 217 is a measure of the damping power.

For oscillation damping the oscillation component is filtered out of the torque current by means of a high pass filter. This is amplified by P217, inverted and switched to the output frequency.

The limit for the value switched is also proportional to P217. The time constant for the high pass filter depends on P213. For higher values of P213 the time constant is lower.

With a set value of 10% for P217, a maximum of ± 0.045Hz are switched in. At 400% in P217, this corresponds to ± 1.8Hz

The function is not active in “Servo mode, P300”.

P218 Modulation depth

[ 100 ]

The modulation depth can be changed between 50% and 110%. Values under 100% limit the voltage at the motor to smaller values than the mains voltage. This is not feasible for typical applications with three-phase asynchronous motors.

Values greater than 100% increase the voltage available at the output, but also the current harmonics, which can lead to oscillation in some motors.

P-component of the encoder (proportional amplification).

Amplification factor, with which the speed difference is multiplied from the setpoint and actual frequency. A value of 100% means that a speed difference of 10% produces a setpoint of 10%. Values that are too high can cause the output speed to oscillate.

P311 (P) Speed controller I

I-component of the encoder (Integration component).

The integration component of the controller completely eliminates any control deviation. The value indicates how large the setpoint change is per ms. Values that are too small cause the controller to slow down (reset time is too long).

Current controller for the torque current. The higher the current controller parameters are set, the more precisely the current setpoint is maintained. Excessively high values in P312 generally lead to highfrequency vibrations at low speeds, on the other hand, excessively high values in P313 generally produce low frequency vibrations across the whole speed range. If the value "Zero" is entered in P312 and P313, then the torque current control is switched off. In this case, only the motor model precontrol is used.

Determines the maximum voltage increase of the torque current controller. The higher the value, the greater is the maximum effect that can be exercised by the field current controller. Excessive values in P317 can specifically lead to instability during transition to the field reduction range (see P320).

P318 (P) P-Weak

ENC POS

0...800 %

[ 150 ]

The field weakening controller reduces the field setpoint when the synchronous speed is exceeded. Generally, the field weakening controller has no function; for this reason, the field weakening controller only needs to be set if speeds are set above the nominal motor speed. Excessive values for P318 / P319 will lead to controller oscillations. The field is not weakened sufficiently if the values are too small or during dynamic acceleration and/or delay times. The downstream current controller can no longer read the current setpoint.

The field weakening limit determines at which speed / current the controller will begin to weaken the field. At a set value of 100% the controller will begin to weaken the field at approximately the synchronous speed.

If values much larger than the standard values have been set in P314 and/or P317, then the field weakening limit should be correspondingly reduced, so that the control range is actually available to the current controller.

The FI analog input can be used for various functions. It must be noted that only one of the functions given below is possible at any time.

0 = Off, the analog input has no function. After the FI has been enabled via the control terminals, it

will supply the set minimum frequency (P104). 1 = Nominal frequency, the given analog range (P402/P403) varies the output frequency between

the set minimum and maximum frequencies (P104/P105). 2 = Torque current limit, based on the set torque current limit (P112), this can be altered by means

of an analog value. 100% setpoint here corresponds to the set torque current limit P112. 20%

cannot be undershot (with P300=1, not below 10%)! 3 = PID current frequency *, is required to build up a control loop. The analog input (actual value) is

compared with the setpoint (e.g. fixed frequency). The output frequency is adjusted as far as

possible until the actual value equals the setpoint. (see Control variables P413 – P415)

4 = Frequency addition *, the supplied frequency value is added to the setpoint. 5 = Frequency subtraction*, the supplied frequency value is subtracted from the setpoint. 6 = Current limit, based on the set current limit (P536), this can be altered via the analog input. 7 = Maximum frequency, the maximum frequency of the FI is set in the analog range. 100%

corresponds to the setting in parameter P411. 0% corresponds to the setting in parameter P410.

The values for the min/max output frequency (P104/P105) cannot be exceeded or undershot. 8 = PID limited current frequency *, like Function 3, PID current frequency, however the output

frequency cannot fall below the programmed minimum frequency value in Parameter P104. (no

change to rotation direction) 9 = PID supervised current frequency *, like Function 3, PID current frequency, however the FI

switches the output frequency off when the minimum frequency P104 is reached.

10 = Servo-Mode Torque, in the Servo mode the motor torque can be set using this function. 11 = Pre-tension Torque, function that enables a value for the anticipated torque requirement to be

entered in the controller (interference factor switching). This function can be used to improve the

load take-up of lift equipment with separate load detection.

12 = Reserved 13 = Multiplication, the setpoint is multiplied with the analog value supplied. The analog value

adjusted to 100% then corresponds to a multiplication factor of 1. 14 = Current value process controller *, activates the process controller, analog input 1 is

connected to the actual value encoder (compensator, air can, flow volume meter, etc.). The

mode (0-10 V or 0/4-20 mA) is set in P401. 15 = Process controller setpoint *: Like Function 14, however the setpoint is specified (e.g. by a

potentiometer). The actual value must be specified using another input. 16 = Process controller precontrol *: Adds an adjustable additional setpoint after the process

controller

Further details regarding the process controller can be found in Chapter 8.2

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

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

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

guideline speed.

0 = 0 – 10V limited: An analog setpoint smaller than the programmed adjustment 0% (P402) does

not lead to undershooting of the programmed minimum frequency (P104). Therefore does not lead to any rotation direction reversal.

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

cause a change in direction rotation. This allows rotation direction reversal using a simple voltage source and potentiometer.

E.g. internal setpoint with rotation direction change

: P402 = 5V, P104 = 0Hz, Potentiometer 0–

10V ⇒ Rotation direction change at 5V in mid-range setting of the potentiometer.

During the reversing moment (hysteresis = ± P505), the drive stands still when the minimum

frequency (P104) is smaller than the absolute minimum frequency (P505). A brake that is controlled by the FI will have entered the hysteresis range.

If the minimum frequency (P104) is greater than the absolute minimum frequency (P505), the

drive reverses when the minimum frequency is reached. In the hysteresis range ± P104, the FI supplies the minimum frequency (P104), the brake controlled by the FI does not enter the range.

2 = 0 – 10V controled: If the minimum

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

Once the setpoint is greater than [P402

an output signal again.

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

can cause a change in direction rotation. This allows rotation direction reversal using a simple voltage source and potentiometer.

have entered the hysteresis range.

If the minimum frequency (P104) is greater than the absolute minimum frequency (P505), the drive reverses when the minimum frequency is reached. In the hysteresis range ± P104, the FI supplies the minimum frequency (P104), the brake controlled by the FI does not enter the range.

[ 100 ]

Analog functions P418 (= 0 ... 14, 30)

Using this parameter an adjustment can be made to the analog output for the selected operating zone. The maximum analog output (10V) corresponds to the standardisation value of the appropriate selection.

If therefore, at a constant working point, this parameter is raised from 100% to 200%, the analog output voltage is halved. 10 Volt output signal then corresponds to twice the nominal value.

For negative values the logic is reversed. A setpoint value of 0% will then produce 10V at the output and 100% will produce 0V.

Digital functions P418 (= 15 ... 27, 44 ... 52)

The switching threshold can be set using this parameter for the functions Current limit (= 17), Torque current limit (= 18) and Frequency limit (= 19). A value of 100% refers to the corresponding motor nominal value (see also P435).

With a negative value, the output function is output negated (0/1 → 1/0).

In certain cases, the FI must start up directly when the mains are switched on. This means that P428 = 1 Æ On can be set. If the enable signal is permanently switched on, or equipped with a cable jumper, the FI starts up immediately.

This function is only possible if the FI is controlled using the digital inputs. (siehe P509)

Following actuation via a digital input and enabling of the FI (right or left), the fixed frequency is used as a setpoint.

A negative setting value will cause a direction change (based on the Enable rotation direction P420 –

P425).

If several fixed frequencies are actuated at the same time, then the individual values are added with the correct sign. This also applies to combinations with the jog frequency (P113), analog setpoint (if P400 = 1) or minimum frequency (P104).

The frequency limits (P104 = f

65 ... 100 %

[ 65 ]

The switching threshold of the brake chopper can be influenced with this parameter. An optimised value for numerous applications is set in the factory setting. This parameter can be increased for applications where pulsating energy is returned (crank drives) to minimise brake resistance power dissipation. An increase in this setting leads to a faster overvoltage FI switch off.

P555 P-limit chopper

5 ... 100 %

[ 100 ]

With this parameter it is possible to program a manual (peak) power limit for the brake resistor. The switch-on delay (modulation level) for the chopper can only rise to a certain maximum specified limit. Once this value has been reached, irrespective of the level of the link voltage, the inverter switches the resistance currentless.

The result would be an overvoltage switch-off of the FI.

Following a stop signal and the braking ramp, a direct current is briefly applied to the motor to fully bring the drive to a stop. Depending on the inertia, the time for which the current is applied can be set in this parameter.

The current level depends on the previous braking procedure (current vector control) or the static boost (linear characteristic).
