Introduction

1. Introduction

1.1. Important Safety Information

Please read the IMPORTANT SAFETY INFORMATION below, and all Warning and Caution information elsewhere.

Danger: Indicates a risk of electric shock, which, if not avoided, could result in damage to the equipment and possible injury or death.

This variable speed drive product (Optidrive) is intended for professional incorporation into complete equipment or systems as part of a ﬁxed installation. If installed incorrectly it may present a safety hazard. The Optidrive uses high voltages and currents, carries a high level of stored electrical energy, and is used to control mechanical plant that may cause injury. Close attention is required to system design and electrical installation to avoid hazards in either normal operation or in the event of equipment malfunction. Only qualiﬁed electricians are allowed to install and maintain this product.

System design, installation, commissioning and maintenance must be carried out only by personnel who have the necessary training and experience. They must carefully read this safety information and the instructions in this Guide and follow all information regarding transport, storage, installation and use of the Optidrive, including the speciﬁed environmental limitations.

Do not perform any ﬂash test or voltage withstand test on the Optidrive. Any electrical measurements required should be carried out with the Optidrive disconnected. Internal surge arrestors are ﬁtted, intended to protect against damage due to mains borne spikes, which will result in the product failing the ﬂash test.

Electric shock hazard! Disconnect and ISOLATE the Optidrive before attempting any work on it. High voltages are present at the terminals and within the drive for up to 10 minutes after disconnection of the electrical supply. Always ensure by using a suitable multimeter that no voltage is present on any drive power terminals prior to commencing any work.

Where supply to the drive is through a plug and socket connector, do not disconnect until 10 minutes have elapsed after turning off the supply.

Ensure correct earthing connections and cable selection as per deﬁned by local legislation or codes. The drive may have a leakage current of greater than 3.5mA; furthermore the earth cable must be sufﬁcient to carry the maximum supply fault current which normally will be limited by the fuses or MCB. Suitably rated fuses or MCB should be ﬁtted in the mains supply to the drive, according to any local legislation or codes.

Do not carry out any work on the drive control cables whilst power is applied to the drive or to the external control circuits.

Within the European Union, all machinery in which this product is used must comply with Directive 98/37/EC, Safety of Machinery. In particular, the machine manufacturer is responsible for providing a main switch and ensuring the electrical equipment complies with EN60204-1.

The level of integrity offered by the Optidrive control input functions – for example stop/start, forward/reverse and maximum speed, is not sufﬁcient for use in safety-critical applications without independent channels of protection. All applications where malfunction could cause injury or loss of life must be subject to a risk assessment and further protection provided where needed.

The driven motor can start at power up if the enable input signal is present.

The STOP function does not remove potentially lethal high voltages. ISOLATE the drive and wait 10 minutes before starting any work on it. Never carry out any work on the Drive, Motor or Motor cable whilst the input power is still applied.

The Optidrive can be programmed to operate the driven motor at speeds above or below the speed achieved when connecting the motor directly to the mains supply. Obtain conﬁrmation from the manufacturers of the motor and the driven machine about suitability for operation over the intended speed range prior to machine start up.

Do not activate the automatic fault reset function on any systems whereby this may cause a potentially dangerous situation.

Optidrives are intended for indoor use only. When mounting the drive, ensure that sufﬁcient cooling is

provided. Do not carry out drilling operations with the drive in place, dust and swarf from drilling may lead to damage.

The entry of conductive or ﬂammable foreign bodies should be prevented. Flammable material should not be placed close to the drive.

Relative humidity must be less than 95% (non-condensing). Ensure that the supply voltage, frequency and no. of phases (1 or

3 phase) correspond to the rating of the Optidrive as delivered. Never connect the mains power supply to the Output terminals

U, V, W. Do not install any type of automatic switchgear between the

drive and the motor. This may cause the drive protection to activate, resulting in a trip and loss of operation.

Wherever control cabling is close to power cabling, maintain a minimum separation of 100 mm and arrange crossings at 90 degrees.

Ensure that all terminals are tightened to the appropriate torque setting.

Do not attempt to carry out any repair of the Optidrive. In the case of suspected fault or malfunction, contact your local Invertek Drives Sales Partner for further assistance.

Danger: Indicates a potentially hazardous situation other than electrical, which if not avoided, could result in damage to property.

The majority of the Optidrive Eco product range is based on a low harmonic solution using ﬁlm capacitor technology to achieve compliance with EN 61000-3-12 without the need for any additional equipment. This standard speciﬁes limits for harmonic currents for equipment connected to public low-voltage systems with input current > 16A and <= 75A per phase. It is important to understand which models from the product range are of the low harmonic technology which is detailed below.

The Optidrive Eco three phase 200V (200-240V) input and three phase 400V (380-480V) input drives frame sizes 2 up to and including frame size 5 are a lower harmonic drive using ﬁlm capacitor technology. Please refer to the product rating tables in section

2.1. Drive Model Numbers for conﬁrmation.

General Information and Ratings

In short, this means that the low harmonic drives do not require an input choke and should not have one installed – drives outside of the above frame sizes and supply voltage / number of phases, are of standard electrolytic capacitor design and could beneﬁt from the use of input chokes if further harmonic reduction is required.

2.2. Identifying the Drive by Model Number

Each drive can be identiﬁed by its model number, shown below. The model number is on the shipping label and the drive nameplate. The model number includes the drive and factory ﬁtted options.

Mechanical Installation

3.4. Installation Following a Period of Storage

Where the drive has been stored for some time prior to installation, or has remained without the main power supply present for an extended period of time, it is necessary to reform the DC capacitors within the drive according to the following table before operation. For drives which have not been connected to the main power supply for a period of more than 2 years, this requires a reduced mains voltage mains voltage to be applied for a time period, and gradually increased prior to operating the drive. The voltage levels relative to the drive rated voltage, and the time periods for which they must be applied are shown in the following table. Following completion of the procedure, the drive may be operated as normal.

3.6. Guidelines for Enclosure mounting (IP20 Units)

  IP20 drives are suitable for use in pollution degree 1 environments, according to IEC-664-1. For pollution degree 2 or higher

environments, drives should be mounted in a suitable control cabinet with sufﬁcient ingress protection to maintain a pollution degree 1 environment around the drive.

Enclosures should be made from a thermally conductive material. Ensure the minimum air gap clearances around the drive as shown below are observed when mounting the drive.  Where ventilated enclosures are used, there should be venting above the drive and below the drive to ensure good air circulation.

Air should be drawn in below the drive and expelled above the drive.

 In any environments where the conditions require it, the enclosure must be designed to protect the Optidrive against ingress of

airborne dust, corrosive gases or liquids, conductive contaminants (such as condensation, carbon dust, and metallic particles) and sprays or splashing water from all directions.

High moisture, salt or chemical content environments should use a suitably sealed (non-vented) enclosure. The enclosure design and layout should ensure that the adequate ventilation paths and clearances are left to allow air to circulate

through the drive heatsink. Invertek Drives recommend the following minimum sizes for drives mounted in non-ventilated metallic enclosures:

4.2. Protective Earth (PE) Connection

4.2.1. Grounding Guidelines

Adequate safety earthing must be provided in accordance with local wiring rules and codes of practice. The ground terminal of each Optidrive should be connected back to the common safety earth bar to maintain touch potentials within safe limits. The ground terminal of each Optidrive should be individually connected DIRECTLY to the site ground bus bar (through the EMC ﬁlter if installed). Optidrive ground connections should not loop from one drive to another, or to, or from any other equipment. Ground impedance must conform to local industrial safety regulations and/or electrical codes.

To meet UL regulations, UL approved ring crimp terminals should be used for all ground wiring connections. The integrity of all ground connections should be checked periodically.

4.2.2. Protective Earth Conductor

The Cross sectional area of the PE Conductor must be at least equal to that of the incoming supply conductors.

4.2.3. Motor Ground

The driven motor must be locally connected to a suitable ground location to maintain touch potentials within safe limits. In addition, the motor ground must be connected to one of the ground terminals on the drive.

4.2.4. Ground Fault Monitoring

As with all inverters, a leakage current to earth can exist. The Optidrive is designed to produce the minimum possible leakage current whilst complying with worldwide standards. The level of current is affected by motor cable length and type, the effective switching frequency, the earth connections used and the type of RFI ﬁlter installed. If an ELCB (Earth Leakage Circuit Breaker) is to be used, the following conditions apply:

A Type B Device must be used. Individual device should be used for each Optidrive. The device must be suitable for protecting equipment with a DC component in the leakage current. The device should be not sensitive to high frequency leakage current.

Supply Cable

A screened (shielded) cable suitable for ﬁxed installation with the relevant mains voltage in use. Braided or twisted type screened

cable where the screen covers at least 85% of the cable surface area, designed with low impedance to HF signals. Installation of a standard cable within a suitable steel or copper tube is also acceptable - in this case, ensure that metal tube is adequately grounded.

A cable suitable for ﬁxed installation with relevant mains voltage with a concentric protection wire. Installation of a standard cable

within a suitable steel or copper tube is also acceptable.

A cable suitable for ﬁxed installation with relevant mains voltage. A shielded type cable is not necessary.

Motor Cable

A screened (shielded) cable suitable for ﬁxed installation with the relevant voltage in use. Braided or twisted type screened

cable where the screen covers at least 85% of the cable surface area, designed with low impedance to HF signals. Installation of a standard cable within a suitable steel or copper tube is also acceptable – in this case, ensure that metal tube is adequately grounded.

The cable shield should be terminated at the motor end using an EMC type gland allowing connection to the motor body through

the largest possible surface area. The shield must also be terminated at the drive end, as close as practically possible to the drive output terminals. Where drives are mounted in a steel control panel enclosure, the cable screen may be terminated directly to the control panel backplate using a suitable EMC clamp or gland ﬁtted as close to the drive as possible. The drive earth terminal must also be connected directly to this point, using a suitable cable which provides low impedance to high frequency currents. For IP55 and IP66 drives, connect the motor cable shield to the gland plate or internal ground clamp.

4.3.4. Wiring Precautions

Connect the Optidrive according to section 4.9. Control Terminal Wiring, ensuring that motor terminal box connections are correct. There are two connections in general: Star and Delta. It is essential to ensure that the motor is connected in accordance with the voltage at which it will be operated. For more information, refer to section 4.6. Drive and Motor Connection.

It is recommended that the power cabling should be 4-core PVC-insulated screened cable, laid in accordance with local industrial regulations and codes of practice.

Version 3.07 | Optidrive Eco User Guide | 21www.invertekdrives.com

4.4. Incoming Power Connection

 Power should be connected to the L1 and L2 terminals for single phase drives, L1, L2 and L3 for three phase drives. Phase

sequence is not important.

 For compliance with CE and C Tick EMC requirements, a symmetrical shielded cable is recommended.  A ﬁxed installation is required according to IEC61800-5-1.  For units without an internal isolator / disconnect, a suitable disconnecting device installed between the Optidrive and the AC

Power Source. The disconnecting device must conform to the local safety code / regulations (e.g. within Europe, EN60204-1, Safety of machinery).

 The cables should be dimensioned according to any local codes or regulations.  Suitable fuses to provide wiring protection of the input power cable should be installed in the incoming supply line, according to

the data in section 11.5. Output Power and Current ratings. The fuses must comply with any local codes or regulations in place. In general, type gG (IEC 60269) or UL type J, T or CC fuses are suitable (exception: Eaton Bussmann FWP series must be used for size 6A & 6B IP20 models); however in some cases type aR fuses may be required. The operating time of the fuses must be below

0.5 seconds.

 Where allowed by local regulations, suitably dimensioned type B MCB circuit breakers of equivalent rating may be utilised in

place of fuses, providing that the clearing capacity is sufﬁcient for the installation.

 When the power supply is removed from the drive, a minimum of 30 seconds should be allowed before re-applying the power.

A minimum of 10 minutes should be allowed before removing the terminal covers or connection.

 The maximum permissible short circuit current at the Optidrive Power terminals as deﬁned in IEC60439-1 is 100kA.

NOTE For IP20 Frame Size 8 it is important that the input supply phase orientation is correct, i.e. L1>L1, L2>L2, L3>L3, failure to do so

Electrical Installation

will result in a “Ph-Seq"trip.

4.5. Input Chokes

 The majority of the Optidrive Eco product range is based on a low harmonic solution using ﬁlm capacitor technology to achieve

compliance with EN 61000-3-12 without the need for any additional equipment. This standard speciﬁes limits for harmonic currents for equipment connected to public low-voltage systems with input current > 16A and <= 75A per phase. It is important to understand which models from the product range are of the low harmonic technology which is detailed below.

 The Optidrive Eco three phase 200V (200-240V) input and three phase 400V (380-480V) input drives frame sizes 2 up to and

including frame size 5 are a lower harmonic drive using ﬁlm capacitor technology.

 In short, this means that the low harmonic drives do not require an input choke and should not have one installed – drives outside

of the above frame sizes and supply voltage / number of phases, could beneﬁt from the use of input chokes if further harmonic reduction is required.

 The low harmonic drives must NOT be used with input chokes. Please see section 2.1.4. Low Harmonic Variants on page 8

for a description of which drives fall into the low harmonic category. Input chokes may be required on the standard (non low harmonic) drives to reduce the harmonics generated or if the incoming supply impedance is low or the fault level / short circuit

current is high.

NOTE For IP20 Frame Size 8 the input current level will vary according to supply impedance. At minimum a 1% line choke must be installed. Installing a 4% line choke further helps towards minimising harmonic current distortion and total current levels. 1% and 4% line chokes are available.

4.6. Drive and Motor Connection

 The drive inherently produces fast switching of the output voltage (PWM) to the motor compared to the mains supply, for motors

which have been wound for operation with a variable speed drive then there is no preventative measures required, however if the quality of insulation is unknown then the motor manufacturer should be consulted and preventative measures may be required.

 The motor should be connected to the Optidrive U, V, and W terminals using a suitable 3 or 4 core cable. Where a 3 core cable

is used, with the shield operating as an earth conductor, the shield must have a cross sectional area at least equal to the phase conductors when they are made from the same material. Where a 4 core cable is utilised, the earth conductor must be of at least equal cross sectional area and manufactured from the same material as the phase conductors.

 The motor earth must be connected to one of the Optidrive earth terminals.  For compliance with the European EMC directive, a suitable screened (shielded) cable should be used. Braided or twisted type

screened cable where the screen covers at least 85% of the cable surface area, designed with low impedance to HF signals are recommended as a minimum. Installation within a suitable steel or copper tube is generally also acceptable.

 The cable screen should be terminated at the motor end using an EMC type gland allowing connection to the motor body through

the largest possible surface area.

 Where drives are mounted in a steel control panel enclosure, the cable screen may be terminated directly to the control panel

using a suitable EMC clamp or gland, as close to the drive as possible.

 

Automatic switchgear should not be installed between the drive output and the motor, opening and closing contacts in this circuit whilst the drive is energised will inevitably reduce the lifetime of the drive and could cause product failure. If an isolator is required to be placed between the drive and the motor in order to comply with local regulations, the device must not be operated when the drive is running.

4.7. Motor Terminal Box Connections

Most general purpose motors are wound for operation on two supply voltage. This will be indicated on the nameplate of the motor. The operational voltage is normally selected when installing the motor by selecting either STAR or DELTA connection. STAR always gives the higher of the two voltage ratings.

4.8. Motor Thermal Overload Protection

4.8.1. Internal Thermal Overload Protection

Optidrive Eco has internal motor overload protection (current limit) set at 110% of the motor rated current (P1-08). This level may be adjusted in P4-07. The drive has an in-built motor thermal overload function; this is in the form of an “I.t-trP” trip after delivering >100% of the value set in P1-08 (motor rated current) for a sustained period of time. The overload accumulator will permit a sustained overload for different durations before tripping as shown in the tables below:

Constant Torque (P4-01 > 0) Variable Torque (P4-01 = 0)

110 % 75 s 75 s 11 0 % 75 s

150% 15 s 15 s 150% 1 s

175 % 10 s – 175 % –

200% 7.5 s – 200% –

Where: HD = Heavy Duty drive selection – this is where the rated current of the motor connected to the drive is less than 75% of the drive

current rating SD = Standard Duty drive selection – this is where the current rating of the motor connected to the drive is closely matched to the drive

current rating

Electrical Installation

When operating in Variable Torque (P4-01 = 0), the oversizing of the drive makes no difference to the available duration of the overload condition.

NOTE The 45kW 400V Eco model (ODV-3-540900-3…) overload capability follows that shown in the variable torque table irrespective of the setting in P4-01.

4.9. Control Terminal Wiring

 All analog signal cables should be suitably shielded. Twisted pair cables are recommended.  Power and Control Signal cables should be routed separately where possible, and must not be routed parallel to each other.  Signal levels of different voltages e.g. 24 Volt DC and 110 Volt AC, should not be routed in the same cable.  Maximum control terminal tightening torque is 0.5Nm.  Control Cable entry conductor size: 0.05 – 2.5mm2 / 30 – 12 AWG.

0/4-20 mA

4.10.1. +24VDC Input / Output

When the mains power is applied to the drive, terminal 1 provides a +24VDC output, maximum load 100mA. This may be used to activate digital inputs or provide power to sensors.

When no mains power is applied to the drive, the drive control electronics may be powered from an external +24VDC source. When powered in this way, all analog and digital I/O and communication functions remain operative, however the motor may not be operated, which allows safe testing and commissioning of the installation without risk of high voltage being present. When powered in this way, the drive requires up to 100mA.

4.10.2. Digital Inputs

Up to ﬁve digital inputs are available. The function of the inputs is deﬁned by parameters P1-12 and P1-13, which are explained in section 8. Control Terminal Functions on page 39.

4.10.3. Analog Inputs

Two analog inputs are available, which may also be used as digital Inputs if required. The signal formats are selected by parameters as follows:

Analog Input 1 Format Selection Parameter P2-30. Analog Input 2 Format Selection Parameter P2-33.

These parameters are described more fully in section 8.1. Digital Input Conﬁguration Parameter P1-13 on page 39. The function of the analog input, e.g. for speed reference or PID feedback for example is deﬁned by parameters P1-12 and P1-13.

The function of these parameters and available options are described in section 8. Control Terminal Functions on page 39.

Two relay outputs are available, which are intended to be used to switch external resistive loads up to 5A at 230 VAC or 30VDC. Relay 1 has both normally open and normally closed contacts available. Relay 2 provides a simple open or closed contact. The relay output function may be conﬁgured using parameters P2-15 and P2-18, which are described in section 8.1. Digital Input

Conﬁguration Parameter P1-13 on page 39.

4.11. Safe Torque Off

Safe Torque OFF will be referred to as “STO” through the remainder of this section.

4.11.1. Responsibilities

The overall system designer is responsible for deﬁning the requirements of the overall “Safety Control System” within which the drive will be incorporated; furthermore the system designer is responsible for ensuring that the complete system is risk assessed and that the “Safety Control System” requirements have been entirely met and that the function is fully veriﬁed, this must include conﬁrmation testing of the “STO” function before drive commissioning.

The system designer shall determine the possible risks and hazards within the system by carrying out a thorough risk and hazard analysis, the outcome of the analysis should provide an estimate of the possible hazards, furthermore determine the risk levels and identify any needs for risk reduction. The “STO” function should be evaluated to ensure it can sufﬁciently meet the risk level required.

4.11.2. What STO Provides

The purpose of the “STO“ function is to provide a method of preventing the drive from creating torque in the motor in the absence of the “STO“ input signals (Terminal 12 with respect to Terminal 13), this allows the drive to be incorporated into a complete safety control system where “STO“ requirements need to be fulﬁlled.

The “STO“ function can typically eliminate the need for electro-mechanical contactors with cross-checking auxiliary contacts as per normally required to provide safety functions.

The drive has the “STO“ Function built-in as standard and complies with the deﬁnition of “Safe torque off“ as deﬁned by IEC 61800-5-2:2007.

The “STO“ Function also corresponds to an uncontrolled stop in accordance with category 0 (Emergency Off), of IEC 60204-1. This means that the motor will coast to a stop when the “STO” function is activated, this method of stopping should be conﬁrmed as being acceptable to the system the motor is driving.

The “STO“ function is recognised as a failsafe method even in the case where the “STO“ signal is absent and a single fault within the drive has occurred, the drive has been proven in respect of this by meeting the following safety standards:

NOTE The values achieved above maybe jeopardised if the drive is installed outside of the Environmental limits detailed in section

11.1. Environmental.

Disconnect and ISOLATE the drive before attempting any work on it. The “STO“ function does not prevent high voltages from being present at the drive power terminals.

NOTE The “STO“ function does not prevent the drive from an unexpected re-start. As soon as the “STO“ inputs receive the relevant signal it is possible (subject to parameter settings) to restart automatically, Based on this, the function should not be used for carrying out short-term non-electrical machinery operations (such as cleaning or maintenance work).

NOTE In some applications additional measures may be required to fulﬁl the systems safety function needs: the “STO“ function does not provide motor braking. In the case where motor braking is required a time delay safety relay and/or a mechanical brake arrangement or similar method should be adopted, consideration should be made over the required safety function when braking as the drive braking circuit alone cannot be relied upon as a fail safe method.

When using permanent magnet motors and in the unlikely event of a multiple output power devices failing then the motor could effectively rotate the motor shaft by 180/p degrees (Where p denotes number of motor pole pairs).

Version 3.07 | Optidrive Eco User Guide | 27www.invertekdrives.com

4.11.3. “STO“ Operation

When the “STO” inputs are energised, the “STO” function is in a standby state, if the drive is then given a “Start signal/command” (as per the start source method selected in P1-13) then the drive will start and operate normally.

When the “STO” inputs are de-energised then the STO Function is activated and stops the drive (Motor will coast), the drive is now in “Safe Torque Off” mode.

4.11.4. “STO” Status and Monitoring

There are a number of methods for monitoring the status of the “STO” input, these are detailed below:

Drive Display

In Normal drive operation (Mains AC power applied), when the drives “STO” input is de-energised (“STO” Function activated) the drive will highlight this by displaying “InHibit”, (NOTE If the drive is in a tripped condition then the relevant trip will be displayed and not “InHibit”).

Drive Output Relay

Drive relay 1: Setting P2-15 to a value of “13” will result in relay opening when the “STO” function is activated. Drive relay 2: Setting P2-18 to a value of “13” will result in relay opening when the “STO” function is activated.

“STO” Fault Codes

4.11.5. “STO” Function response time

The total response time is the time from a safety related event occurring to the components (sum of) within the system responding and becoming safe. (Stop Category 0 in accordance with IEC 60204-1).

  The response time from the “STO” inputs being de-energised to the output of the drive being in a state that will not produce

torque in the motor (“STO” active) is less than 1ms.

The response time from the “STO” inputs being de-energised to the “STO” monitoring status changing state is less than 20ms.  The response time from the drive sensing a fault in the STO circuit to the drive displaying the fault on the display/Digital output

showing drive not healthy is less than 20ms.

A fault has been detected within either of the

internal channels of the “STO” circuit.

4.11.6. “STO“ Electrical Installation

The “STO” wiring shall be protected from inadvertent short circuits or tampering which could lead to failure of the “STO” input signal, further guidance is given in the diagrams below.

In addition to the wiring guidelines for the “STO” circuit below, section 4.3. EMC Compliant Installation should also be followed. The drive should be wired as illustrated below; the 24Vdc signal source applied to the “STO” input can be either from the 24Vdc on

the drive or from an External 24Vdc power supply.

4.11.10. Enabling the “STO” Function

The “STO” function is always enabled in the drive regardless of operating mode or parameter changes made by the user. In order to ensure that the drive does not immediately re-start when the STO is energised, the 'start mode' (P2-36) should be set to 'Edge-r' as opposed to the default value of 'Auto-0'. This means that when the drive is ready to run (STO active and drive healthy), it will only start when it sees a rising edge on the run command.

4.11.11. Testing the “STO” Function

Before commissioning the system the “STO” function should always be tested for correct operation, this should include the following tests:

With the motor at standstill, and a stop command given to the drive (as per the start source method selected in P1-13): o De-energise the “STO” inputs (Drive will display “InHibit”). o Give a start command (as per the start source method selected in P1-13) and check that the drive still displays “Inhibit” and that

the operation is in line with the section 4.11.3. “STO“ Operation and 4.11.4. “STO” Status and Monitoring on page 28.

With the motor running normally (from the drive): o De-energise the “STO” inputs. o Check that the drive displays “InHibit” and that the motor stops and that the operation is in line with the section 4.11.3. “STO“

Operation and 4.11.4. “STO” Status and Monitoring “STO” Function Maintenance.

The “STO” function should be included within the control systems scheduled maintenance program so that the function is regularly tested for integrity (Minimum once per year), furthermore the function should be integrity tested following any safety system modiﬁcations or maintenance work.

6. Commissioning

6.1. General

The following guidelines apply to all applications:

6.1.1. Entering the Motor Nameplate Information

Optidrive Eco uses the information from the motor nameplate to:

  Operate the mot or with the best possible efﬁciency level.   Protect the motor against possible damage due to operation in overload condition.

In order to achieve this, the Optidrive requires that the following information from the motor nameplate is entered into the parameters: P1-07 Motor Rated Voltage. This is the operating voltage for the motor in its present wiring conﬁguration (Star or Delta). The

maximum output voltage from the Optidrive can never exceed the incoming supply voltage.

P1-08 Motor Rated Current. This is the full load current of the motor from the nameplate. P1-09 Motor Rated Frequency. This is the standard operating frequency of the motor, generally 50 or 60Hz. P1-10 Motor Rated Speed. This parameter can optionally be set to the Rpm shown on the motor nameplate. When this

parameter is entered, all speed related parameters in the drive are displayed in Rpm. When the parameter is set to zero, all speed related parameters are displayed in Hz.

6.1.2. Minimum and Maximum Frequencies / Speeds

Optidrive Eco units are factory set to operate the motor from zero up to base speed (50 or 60Hz output). In general, this operating range is suitable for a wide range of requirements, however in some cases it may be desired to adjust these limits, e.g. where the maximum speed of a fan or pump may provide excessive ﬂow, or where operation below a certain speed is never required. In this case, the following parameters can be adjusted to suit the application:

P1-01 Maximum Frequency. In general this should match the motor rated frequency. If operation above this frequency is desired, conﬁrmation from the motor manufacturer, and the manufacturer of any connected fan or pump should be sought that this is permissible, and will not cause damage to the equipment.

P1-02 Minimum Frequency. A suitable minimum can be set to prevent the motor operating at low speed, which may cause the motor to overheat. In some applications, such as a pump circulating water through a boiler, it may be necessary to set a speed to

Commissioning

ensure the boiler does not run dry during operation.

6.1.3. Acceleration and Deceleration Ramp Times

Optidrive Eco units are factory set with acceleration and deceleration ramp rates set to 30 seconds. The default value is suitable for the majority of applications but can be altered by changing the values in parameters P1-03 and P1-04. Care must be taken to ensure the driven load is capable of performing the speciﬁed ramps and that nuisance trips due to excessively short ramp times are not produced.

The ramp times entered in the parameter set always specify the time taken to ramp between 0Hz and motor rated speed P1-09. For example: If ramp rate = 30 seconds and P1-09 (motor vase speed) = 50Hz, and assuming the motor is currently running at 25Hz

and the drive is commanded to accelerate to 50Hz. The time taken to reach 50Hz would be 30 seconds (P1-03) / 50 (P1-09) * 25 (required change in speed) = 15(s).

P1-03 Acceleration Ramp Rate: Time taken for the drive to accelerate the motor from 0Hz to Motor base speed, P1-09 in seconds. P1-04 Deceleration Ramp Rate: Time taken for the drive to decelerate the motor from Motor base speed, P1-09 to 0Hz in seconds.

6.1.4. Stop Mode Selection

Optidrive Eco units can be programmed to either apply a ﬁxed deceleration to the motor during stopping, or to release control of the motor and allow it to coast or free-wheel to a stop. The default selection is for the drive is ramp to stop and behaviour is programmed using parameter P1-05.

P1-05 Stop Mode Select: Deﬁnes how the motor will be stopped in the event of the enable input being removed from the drive. Ramp to stop (P1-05 = 0) will ramp the drive to stop using the value for deceleration entered in P1-04. Coast to stop (P1-05 = 1) will allow the motor to coast to stop (uncontrolled).

6.1.5. Voltage Boost

Voltage boost is used to increase the applied motor voltage at low output frequencies, in order to improve low speed and starting torque. Excessive boost levels may result in increased motor current and temperature, and force ventilation of the motor may be required.

The default value for Torque boost is set 0.0%, and this should only be increased if the starting torque is insufﬁcient. Ensure that the correct Constant or Variable Torque mode is set in P4-01 before adjusting the boost.

P1-11 Torque Boost: Set as a percentage of motor rated voltage P1-07.

7. Parameters

7.1. Parameter Set Overview

The Optidrive Eco Extended Parameter set consists of 7 groups as follows:

Group 1 – Basic Parameter Set Group 2 – Extended Parameter Set Group 3 – User PID Control Parameter Set Group 4 – Motor Control Parameters Group 5 – Field Bus Communications Parameter Set Group 8 – Application Speciﬁc Functions Parameter Set Group 0 – Monitoring and Diagnostic Parameters (Read Only).

When the Optidrive is reset to factory defaults, or is in its factory supplied state, only Group 1 Parameters can be accessed. In order to allow access to parameters from the higher level groups, P1-14 must be set to the same value as P2-40 (Default setting =

101). With this setting, parameter groups 1 – 5 and group 8 can be accessed, along with the ﬁrst 39 parameters in Group 0. These parameters are listed in the tables below.

For advanced parameter access, P1-14 can be set to the same value as P6-30 (Default setting = 201), which allows access to all parameter groups and ranges. Advanced parameter descriptions are listed in the advanced user guide.

Values given in brackets () are default settings for horsepower rated drive models.

Parameters

This parameter can optionally be set to the rated (nameplate) Rpm of the motor. When set to the default value of zero, all speed related parameters are displayed in Hz, and the slip compensation for the motor is disabled. Entering the value from the motor nameplate enables the slip compensation function, and the Optidrive display will now show motor speed in estimated Rpm. All speed related parameters, such as Minimum and Maximum Speed, Preset Speeds etc. will also be displayed in Rpm.

Dependent

Torque Boost is used to increase the applied motor voltage and hence current at low output frequencies. This can improve low speed and starting torque. Increasing the boost level will increase motor current at low speed, which may result in the motor temperature rising - force ventilation of the motor may then be required. In general, the lower the motor power, the higher the boost setting that may be safely used.

For IM motors, a suitable setting can usually be found by operating the motor under very low or no load conditions at approximately 5Hz, and adjusting P1-11 until the motor current is approximately the magnetising current.

This parameter is also effective when using alternative motor types, P4-01 = 3, 4 or 5. In this case, the boost current level is deﬁned as 4 x P1-11 x P1-08.

9.2. Parameter Group 3 – PID Control

Par. Parameter Name Minimum Maximum Default Units

P3-01 PID Proportional Gain 0.1 30.0 1. 0 -

PID Controller Proportional Gain. Instantaneous error between the feedback and the set-point in the PID controller is multiplied by P3-01 to produce the output from the PID controller. Higher values of proportional gain produce a larger change in the drive output frequency in response to changes in the PID set-point or feedback signals. Too high a value can cause instability.

P3-02 PID Integral Time 0.0 30.0 1.0 Seconds

PID Controller Integral Time. Accumulated error in the PID control. Uses accumulated errors between set-point and feedback signals to inﬂuence the output from the PID controller. P3-02 is the time constant for accumulating error. Larger values provide a more damped response. Lower values result is a faster system response but may result in instability.

P3-03 PID Differential Time 0.00 1.00 0.00 Seconds

PID Differential Time Constant. The Differential time constant references the rate of change of the feedback signal over time and works to slow the rate of change of the PID controller, particularly as it approached the set-point. Setting a shorter time will decrease overshoot but slow down response and may lead to instability.

NOTE P3-03 is set to 0 by default which disables the differential time constant. Care must be taken when adjusting this value outside of its default value.

P3-04 PID Operating Mode 0 1 0 -

0 : Direct operation. Use this mode if an increase in the feedback signal should result in an decrease in the motor speed. 1 : Inverse operation. Use this mode if an increase in the feedback signal should result in an increase in the motor speed.

applied to Analog Input 1. 2 : Lower limit set by analog input 1. The output range of the PID controller is limited by the signal applied to Analog Input 1

Extended Parameters

Deﬁnes a threshold PID error level, whereby if the difference between the set-point and feedback value is less than the set threshold, the internal ramp times of the drive are disabled to allow the drive to react quickly to small errors. Where a greater PID error exists, the ramp times are enabled to limit the rate of change of motor speed.

Setting to 0.0 means that the drive ramps are always enabled. This parameter is intended to allow the user to disable the drive internal ramps where a fast reaction to the PID control is required, however by only disabling the ramps when a small PID error exists, the risk of possible over current or over voltage trips being generated are reduced.

Applies a scaling factor to the displayed PID feedback, allowing the user to display the actual signal level from a transducer, e.g. 0 – 10 Bar etc.

Sets a programmable PID Error Level whereby if the drive enters standby mode whilst operating under PID control, the difference between the PID reference and PID feedback signals must exceed this error level to restart the PID controller.

Determines the level at which the drive will enter into standby mode. P2-27 must be set with a value (time) for standby function to be active. Drive enters standby mode if motor speed remains below the level set in P3-14 for the time period set in P2-27.

When P3-05 = 0, and the 2nd digital reference is selected (see section 8.1. Digital Input Conﬁguration Parameter P1-13) this parameter sets the preset digital reference (set-point) used for the PID Controller.

A value other than zero in this parameter will automatically enable the burst pipe detection function. Each time the drive is enabled whilst in PID control or is switched to PID control, the drive will monitor the PID feedback level for the time entered in P3-16. If the PID feedback level does not exceed the threshold entered in P3-17 before the time in P3-16 expires then the drive will trip with "Pr-Lo" (pressure low) trip.

PID feedback threshold for the burst pipe detection. In direct PID mode, PID feedback should be equal to or greater than this threshold before the pump prime time (P3-16) expires. In inverse PID mode, PID feedback should be less than or equal to the threshold before the pump prime time (P3-16) expires.

0 : Continuous Run. PID loop will continue running as long as P gain (P3-01) is not zero. 1 : On drive Enable. PID loop will only run when the drive is enabled. If the drive is not running, PID output will reset to 0 (Including

integral result).

When burst pipe detection is enabled by conﬁguring parameters P3-16 & P3-17, this parameter adds a delay/ﬁlter to the “Pr-Lo” trip. This can be useful in situations where the system has been operating in steady state and sudden closing and then re-opening of valves can cause an overshoot of pressure followed by an undershoot which could trigger the “Pr-Lo” trip unnecessarily.

Par. Parameter Name Minimum Maximum Default Units

P4-03 Vector Speed Controller Proportional Gain 0.1 400.0 50.0 %

Sets the proportional gain value for the speed controller. Higher values provide better output frequency regulation and response. Too high a value can cause instability or even over current trips. For applications requiring best possible performance, the value should be adjusted to suit the connected load by gradually increasing the value and monitoring the actual output speed of the load until the required dynamic behaviour is achieved with little or no overshoot where the output speed exceeds the setpoint.

In general, the factory set value will be suitable for most fan and pump applications, higher friction loads can tolerate higher values of proportional gain, and high inertia, low friction loads may require the gain to be reduced.

P4-04 Vector Speed Controller Integral Time Constant 0.010 2.000 0.050 Seconds

Sets the integral time for the speed controller. Smaller values provide a faster response in reaction to motor load changes, at the risk of introducing instability. For best dynamic performance, the value should be adjusted to suit the connected load.

P8-01 Pump Stir Interval Duration 0 60000 0 Minutes

Extended Parameters

P8-02 Pump Stir Activation Time 1 6000 10 Seconds

P8-03 Pump Clean Function Select 0 3 - -

P8-04 Pump Clean Time 0 600 0 Seconds

P8-05 Pump Clean Function Ramp Time 0 6000 30 Seconds

This parameter can be used to set a pre-deﬁned period of inactivity, whereby if the drive remains in standby mode for a period of time exceeding the limit, stir function is activated, and the drive will operate at preset speed 7 (P2-07) for the time set in P8-02. This allows the pump to stir, preventing sediment from settling and avoiding a blockage.

Set the time period that the stir function will be active once triggered (excludes time for deceleration to stop).

This parameter conﬁgures the drive conditions that will cause activation of the automatic pump clean function. When activated, the pump clean will operate the pump at preset speed 5 (P2-05) for the time period set in P8-04, followed by Preset Speed 6 (P2-06) (Providing P2-06 <> 0) for the time set in P8-04, before resuming normal operation. During the cleaning cycle, the ramp time set in P805 is used for both acceleration and deceleration, and overrides P1-03 and P1-04.

Where possible, P2-05 and P2-06 may be set to negative values, to allow the pump to be reversed. For best results, it is recommended to use as high a speed as possible, and to adjust P8-05 to allow a short acceleration time whilst avoiding over current trips.

0 : Disabled. 1 : Active on start-up only. The pump cleaning function operates every time the pump is started. 2 : Active on start-up and high current detection. The pump cleaning function operates every time the pump is started,

and also in the event that the drive detects a possible pump blockage during normal operation. This requires the Motor Current Proﬁle Monitoring function to be active and commissioned for correct operation, see parameter P8-06.

3 : Active on high current detection only. The pump cleaning function operates only when a possible pump blockage is detected during normal operation. This requires the Motor Current Proﬁle Monitoring function to be active and commissioned for correct operation, see parameter P8-06.

NOTE The pump clean function can also be activated by digital input conﬁgured in group 9 parameters.

Sets the time period for the operation of the pump cleaning cycle. When bi-directional pump cleaning is selected, the time interval is used twice, once in each direction.

Independent ramp rate used only for the pump automatic cleaning function (see P8-03) when the motor is Accelerated as part of the cleaning cycle.

Par. Name Minimum Maximum Default Units

P8-06 Load Monitor Enable 0 4 0 -

This parameter enables the Total Motor Current Proﬁle Monitoring Function, which can be used to detect belt failure in belt driven fan applications, or Dry Pump, Pump Blockage or broken impeller in Pump applications.

0 : Disabled 1 : Low Current Detection Enabled (Belt Failure / Dry Pump / Broken Impeller) 2 : High Current Detection Enabled (Pump Blockage) 3 : Low and High Current Detection 4 : Low and High Current Detection, warning only. Bit 7 of the status word goes high in the event of a high or low current

being detected but the drive will not trip.

Adjustment of parameter P8-06 (<>0) will cause the drive to automatically run the motor through its programmed frequency range upon the next drive enable (input enable). Ensure the application is in a suitable condition to allow the motor to run safely through its frequency range prior to enabling this feature.

P8-07 Load Proﬁle Bandwidth 0.1 50.0 1.0 Amps

This parameter sets a bandwidth around the Motor Current proﬁle generated by P8-06. If P8-06 has been set to an appropriate value to detect a high /low current condition and the drive operates outside of the bandwidth set in P8-07 for a period longer than that deﬁned by P8-08 then the drive will trip. Value entered in P8-07 is the value between the normal current and the trip level, hence total bandwidth for the function is 2 x P8-07.

P8-08 Load Monitor Trip Delay 0 60 0 Seconds

This parameter sets a time limit for the Motor Current proﬁle generated by P8-06. If P8-06 has been set to an appropriate value to detect a

high /low current

08 and then the drive will trip.

P8-09 Fire Mode Logic 0 1 0 -

When Fire mode is assigned to a digital input on the drive then the logic conﬁguration for the input is set by P8-09 to allow normally open or normally closed activation. Default behaviour is for Input logic off (0) to activate ﬁre mode (Open activation).

Input conﬁguration for Fire mode is set by parameter P1-13 or can be user deﬁned by the setting of P9-32.

0 : Open Activation 1 : Closed Activation

P8-10 Fire Mode Speed -P1-01 P1-01 5 Hz / Rpm

When set to a non-zero value, this parameter sets an operational ﬁxed frequency / speed used when Fire Mode is selected. The drive will maintain operation at this frequency until the ﬁre mode signal is removed or the drive is no longer able to sustain operation.

When P8-10 is zero, and ﬁre mode is activated, the drive will continue to operate under the control of the selected speed reference, dependent on parameter settings and digital input selection.

P8-11 Bypass Mode on Fault 0 1 0 -

Parameter conﬁgures the drive to switch to bypass mode automatically should a trip occur on the drive. When enabled the drive standard relays 1 and 2 are dedicated to bypass control and cannot be assigned other functions.

0 : Disabled 1 : Enabled

P8-12 Bypass In Fire Mode 0 1 0 -

Parameter conﬁgures the drive to switch to bypass mode automatically should an input to the drive be conﬁgured for Fire Mode operation and that input becomes active. When enabled the drive standard relays 1 and 2 are dedicated to bypass control and cannot be assigned other functions.

0 : Disabled 1 : Enabled

P8-13 Bypass Contactor Change Over Time 0 30 2 Seconds

Parameter active when Bypass function is enabled. Parameter P8-05 sets a time delay or changeover time between the switching of the drive relays controlling the bypass circuitry.

Care must be taken when setting P8-13 to ensure that drive and DOL contactors are not switched in circuit simultaneously. Both

Mechanical and Electrical interlocking of drive and DOL contactors to regional standards are recommended in conﬁguring the Bypass function.

P8-20 Pump Master Clock Reset 0 1 0 -

Parameter enables the pump staging (cascade) function on the drive.

0 : Disabled 1 : Single VFD with DOL Cascade (max 4 DOL pumps) 2 : Multiple Drive Cascade (Optiﬂow) Master Drive. (Only valid when drive set to Optibus master address, P5-01 = 1). 3 : Multiple Drive Cascade with Jockey Pump (Optiﬂow). Master Drive (Only valid when drive set to Optibus master

address, P5-01 = 1) In this instance, the Master drive (with address P5-01 =1) will remain active and will not be switched off to support the pump rotation ordinarily used for the purpose of sharing operating hours across all pumps.

4 : Multiple Drive Cascade Mode 2 (Optiﬂow) Master Drive. (Only valid when drive set to Optibus master address, P5-01 = 1) This mode is similar to mode 2 but the settling time works differently which can prevent multiple motors starting simultaneously when waking up from PID Standby mode.

5 : Multiple Drive Cascade with Jockey Pump Mode 2 (Optiﬂow) Master Drive. (Only valid when drive set to Optibus master address, P5- 01 = 1) This mode is the same as mode 3 except that when an assist pump starts, the lead pump (jockey pump) will stop. When the assist pump goes into standby mode, the lead pump (jockey pump) will start again.

Parameter valid when P8-14 is set to 1 or 2 to enable Pump Staging Function. P8-15 set the number of assist pumps (P8-14 = 1) or network slave drives (P8-14 = 2) that are available in the Pump Staging application. Setting the value to 0 disables Pump Staging.

In order to balance run time (duty) on each pump in the Pump staging application and to ensure periodic operation of each pump P8-16 can be set with a time limit for pump switch over. When set to a value other than 0 (disabled) the operation of each staging pump will be cycled to ensure the difference in duty between each pump does not exceed the time set in P8-16.

This parameter deﬁnes the speed at which an “Assist” Pump is started when using the Pump Cascade or Optiﬂow feature. When the drive output increases beyond this threshold the next Staging pump is switch on. The Pump staging settle time must then expire before additional staging pumps can be brought on or off line. Priority for Staging pump switch on is always given to the pump with lowest run time accumulated.

This parameter deﬁnes the speed at which an “Assist” Pump is stopped when using the Pump Cascade or Optiﬂow feature. When the drive output decreases below this threshold one of the Staging pumps currently operating is switch off. The Pump staging settle time must then expire before additional staging pumps can be brought on or off line. Priority for Staging pump switch off is always given to the pump with highest run time accumulated.

Parameter sets a time delay for pump staging whereby, following switch in or switch out of a staging pump, further pumps are not permitted to be switched in or out until this time period has elapsed. This parameter should be set to allow adequate settle time between staging pump transitions.

Master drive in pump staging monitors and maintains duty run times for all available staging pumps. All clocks are available to view in P0-20. P8-20 provides the master reset to all run time clocks used for Pump Staging Function (all clocks set to 0).

9.7. Fire Mode

The Fire Mode function is designed to ensure continuous operation of the drive in emergency conditions until the drive is no longer capable of sustaining operation.

The Fire Mode input may be Normally Open (Close to Activate Fire Mode) or Normally Closed (Open to Activate Fire Mode) according to the setting of P8-09. This input may be linked to a ﬁre control system to allow maintained operation in emergency conditions, e.g. to clear smoke or maintain air quality within the building. The ﬁre mode function is enabled when P1-13 = 4, 8 or 13 with Digital Input 2 assigned to activate ﬁre mode or can be user deﬁned by the setting of P9-32 when P1-13 = 0.

Fire Mode disables the following protection features in the drive: O-t (Heat-sink Over-Temperature), U-t (Drive Under Temperature), Th-FLt (Faulty Thermistor on Heat-sink), E-trip (External Trip), 4-20 F (4-20mA fault), Ph-Ib (Phase Imbalance), P-Loss (Input Phase Loss Trip), SC-trp (Communications Loss Trip), I.t-trp (Accumulated overload Trip). The following faults will result in a drive trip, auto reset and restart: O-Volt (Over Voltage on DC Bus), U-Volt (Under Voltage on DC Bus), h O-I (Fast Over-current Trip), O-I (Instantaneous over current on drive output), Out-F (Drive output fault, Output stage trip).

When Fire Mode is activated, the drive will enter Fire Mode but will run from the existing control source selected – it will require the run signal and relevant speed reference.

If Fire Mode speed is set (<>0) in P8-10, when ﬁre mode is activated, the drive will enter Fire Mode and run at the speed set in P8-10 and will ignore all other terminals with the exception of the STO.

The connector contains two independent RS485 connections, one for Invertek’s Optibus Protocol and one for Modbus RTU / BACnet MSTP. Both connections can be used simultaneously.

The electrical signal arrangement of the RJ45 connector is shown as follows:

1 Not used

2 Not used

3 0 Volts

4 -RS485 (PC)

5 +RS485 (PC)

6 +24 Volt

7 RS 485- Modbus RTU / BACnet MSTP

8 RS 485+ Modbus RTU / BACnet MSTP

Warning:

This is not an Ethernet connection. Do not connect directly to an Ethernet port.

Warning:

When using Modbus RTU or BACnet, ensure that the 0V signal (T3) is also used to avoid comms errors and potentially damaging common mode voltages.

  The Optibus data link is only used for connection of Invertek peripherals and inter-drive communication.   The Modbus interface allows connection to a Modbus RTU network as described in section 10.2. Modbus RTU Communications.

Modbus RTU and BACnet MSTP connection should be made via the RJ45 connector. The pin assignments are as shown in section

11.1. RS-485 communications.   Modbus RTU and BACnet MSTP networks require three conductors for best operation and to eliminate common mode voltages

on the drive terminals: o RSR85+ o RS485 o 0 Volt Common

  Connection should be made using a suitable dual twisted pair, shielded cable, with a wave impedance of 120R.   Use one of the twisted pairs to connect to the RS485+ and RS485- of each drive.   Use one conductor of the remaining pair to connect together all the 0 volt common connection terminals.   The cable shield should be connected to a suitable clean ground point to prevent interference with the screen maintained as close

as possible to the cable terminations.

  Do not connect the 0 Volt Common, RS485- or RS485+ to ground at any point.   Network terminating resistor (120R) should be used at the end of the network to reduce noise.

10.2. Modbus RTU Communications

10.2.1. Modbus Telegram Structure

The Optidrive Eco supports Master / Slave Modbus RTU communications, using the 03 Read Multiple Holding Registers and 06 Write Single Holding Register commands and 16 Write Multiple Holding Registers (Supported for registers 1 – 4 only). Many Master devices treat the ﬁrst Register address as Register 0; therefore it may be necessary to convert the Register Numbers detail in section

10.2.2 by subtracting 1 to obtain the correct Register address.

10.2.2. Modbus Control & Monitoring Registers

The following is a list of accessible Modbus Registers available in the Optidrive Eco.

  When Modbus RTU is conﬁgured as the Fieldbus option, all of the listed registers can be accessed.   Registers 1 and 2 can be used to control the drive providing that Modbus RTU is selected as the primary command source

(P1-12 = 4) and no Fieldbus Option Module is installed in the drive Option Slot.   Register 4 can be used to control the acceleration and deceleration rate of the drive providing that Fieldbus Ramp Control is

enabled (P5-07 = 1).   Registers 6 to 24 can be read regardless of the setting of P1-12.

This register contains 2 bytes. The Lower Byte contains an 8 bit drive status word as follows: Bit 0 : 0 = Drive Disabled (Stopped), 1 = Drive Enabled (Running). Bit 1 : 0 = Drive Healthy, 1 = Drive Tripped. Bit 2: 0 = Auto, 1 = Hand. Bit 3 : Inhibit. Bit 4 : Service due. Bit 5 : Standby. Bit 6 : Drive Ready. Bit 7 : 0 = Normal condition, 1 = Low or High Load condition detected. The Upper Byte will contain the relevant fault number in the event of a drive trip. Refer

to section 13.1 for a list of fault codes and diagnostic information.

10.2.3. Modbus Parameter Access

All User Adjustable parameters (Groups 1 to 5) are accessible by Modbus, except those that would directly affect the Modbus communications, e.g.

  P5-01 Drive Fieldbus Address – see also P5-16 Drive Modbus Address.   P5-03 Modbus RTU Baud Rate.   P5-04 Modbus RTU Data Format.

All parameter values can be read from the drive and written to, depending on the operating mode of the drive – some parameters cannot be changed whilst the drive is enabled for example.

When accessing a drive parameter via Modbus, the Register number for the parameter is the same as the parameter number, e.g. Parameter P1-01 = Modbus Register 101. Modbus RTU supports sixteen bit integer values, hence where a decimal point is used in the drive parameter, the register value will be

multiplied by a factor of ten, e.g. Read Value of P1-01 = 500, therefore this is 50.0Hz. For further details on communicating with Optidrive using Modbus RTU, please refer to your local Invertek Sales Partner.

10.3. BACnet MSTP

10.3.1. Overview

Optidrive Eco provides an interface for direct connection to a BACnet MSTP network. Connection is made via the RJ45 connection port, see section 10.1. RS-485 Communications for terminal assignment and section 10.1.1. RS-485 Communications Electrical Connections for wiring requirements.

10.3.2. Interface Format

Protocol : BACnet MSTP Physical signal : RS485, half duplex Interface : RJ45 Baudrate : 9600bps, 19200bps, 38400bps, 76800bps Data format : 8N1, 8N2, 8E1, 8O1

10.3.3. BACnet MSTP Parameters

The following parameters are used to conﬁgure the drive when connecting to a BACnet MSTP network.

Par. Parameter Name Description

P1-12 Control Source Set this parameter to 6 to activate BACnet MSTP operation.

P5-01 Drive Address

P5-03 Baudrate

P5-04 Data Format

P5-07 Fieldbus Ramp Control

P5-09 BACnet Device Instance ID Low P5-09 and P5-10 are used to setup drive device instance ID value.

P5-10 BACnet Device Instance ID High

Serial Communications

P5-11 Max Master Set BACnet MS/TP max master property, range from 1 ~ 127. Default set to 127.

This parameter is used to set the drive address on the BACnet network. Each drive on a given network should have a unique value. By default, all drives are set to MAC ID 1.

This parameter is used to set up communication baudrate. It should be set to match the chosen baudrate of the BACnet system. Auto baudrate is not supported.

Use this parameter to set RS485 communication data format. Possible settings are as follows: n-1 : No parity, one stop bit (default setting) n-2 : No parity, two stop bits O-1 : Odd parity, one stop bit E-1 : Even parity, one stop bit The setting must match the requirement of the BACnet network.

This parameter determines whether the acceleration and deceleration time of the drive is controlled by the drive internal parameters (P1-03 : Acceleration Time, P1-04 : Deceleration Time), or controlled directly from the BACnet MSTP network. In most cases, using the drive internal parameters is the best solution.

Instance ID = (P5-10 * 65536) + P5-09. The allowed setting range is Range from 0 ~ 4194304. Default value is set to 1.

10.3.4. BACNet MSTP Commissioning

In order to connect the drive and operate on a BACnet MSTP network, the following procedure should be used.

1. Set P1-14 = 101 to allow access to the extended parameters.

2. On each drive, set an unique Drive Address in parameter P5-01.

3. Set the required baudrate in P5-03.

4. Select the required data format in P5-04.

5. Deﬁne a unique BACnet Device Instance ID for each drive using parameters P5-09 and P5-10.

6. Select control from BACnet connection by setting P1-12 = 6.

Derate by Maximum Permissible

11.8.4. Example of Applying Derating Factors

A 4kW, IP66 drive is to be used at an altitude of 2000 metres above sea level, with 16 kHz switching frequency and 45°C ambient temperature.

From the table above, we can see that the rated current of the drive is 9.5 Amps at 40°C, Firstly, apply the switching frequency derating (if any), 16 kHz, 0% derating. Now, apply the derating for higher ambient temperature, 2.5% per °C above 40°C = 5 x 2.5% = 12.5%

9.5 Amps x 87.5% = 8.3 Amps. Now apply the derating for altitude above 1000 metres, 1% per 100m above 1000m = 10 x 1% = 10%

8.3 Amps x 90% = 7.5 Amps continuous current available. If the required motor current exceeds this level, it will be necessary to either:

Reduce the switching frequency selected; or Use a higher power rated drive and repeat the calculation to ensure sufﬁcient output current is available.

Check the motor and motor connection cable for phase – phase and phase – earth short circuits.

Check the load mechanically for a jam, blockage or stalled condition. Ensure the motor nameplate parameters are correctly entered, P1-07, P1-08,

P1-09. Reduced the Boost voltage setting in P1-11. Increase the ramp up time in P1-03. If the connected motor has a holding brake, ensure the brake is correctly

connected and controlled, and is releasing correctly.

Check to see when the decimal points are ﬂashing (drive in overload) and either increase acceleration rate or reduce the load.

Check motor cable length is within the limit speciﬁed for the relevant drive in section 11.5. Output Power and Current ratings.

Ensure the motor nameplate parameters are correctly entered in P1-07, P1-08, and P1-09.

Check the load mechanically to ensure it is free, and that no jams, blockages or other mechanical faults exist.

For a centrifugal fan or pump, a small reduction in output frequency could signiﬁcantly reduce the load.

Check the wiring to motor and the motor for phase to phase and phase to earth short circuits. Disconnect the motor and motor cable and retest. If the drive trips with no motor connected, it must be replaced and the system fully checked and retested before a replacement unit is installed.

The value of the DC Bus Voltage can be displayed in P0-20. A historical log is stored at 256ms intervals prior to a trip in parameter P0-36. This fault is generally caused by excessive regenerative energy being

transferred from the load back to the drive. When a high inertia or over hauling type load is connected.

If the fault occurs on stopping or during deceleration, increase the deceleration ramp time P1-04.

If operating in PID control, ensure that ramps are active by reducing P3-11.

This occurs routinely when power is switched off. If it occurs during running, check the incoming supply voltage, and all

connections into the drive, fuses, contactors etc.

The heatsink temperature can be displayed in P0-21. A historical log is stored at 30 second intervals prior to a trip in P0-38. Check the drive ambient temperature. Ensure the drive internal cooling fan is operating. Ensure that the required space around the drive as shown in section 3.6.

Guidelines for Enclosure mounting (IP20 Units) thru 3.8. Guidelines for Mounting (IP55 Units) has been observed, and that the cooling airﬂow path to

and from the drive is not restricted. Reduce the effective switching frequency setting in parameter P2-24. Reduce the load on the motor / drive.

Trip occurs when ambient temperature is less than -10°C. The temperature must be raised over -10°C in order to start the drive.

Press STOP key, the drive is now ready to be conﬁgured for the required application. Four button defaults – see section 5.4. Changing Parameters.

E-trip requested on control input terminals. Some settings of P1-13 require a normally closed contact to provide an external means of tripping the drive in the event that an external device develops a fault. If a motor thermistor is connected check if the motor is too hot.

Communications lost with PC or remote keypad. Check the cables and connections to external devices.
