Introduction

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

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

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.

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 the Machinery Directive 2006/42/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.

IP55 and IP66 drives provide their own pollution degree 2 environments. IP20 drives must be installed in a pollution degree 2 environment, mounted in a cabinet with IP54 or better.

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

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.

3.5. 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:-

3.6. Mounting the Drive – IP20 Units

 IP20 Units are intended for installation within a control cabinet.  When mounting with screws

o Using the drive as a template, or the dimensions shown above, mark the locations for drilling o Ensure that when mounting locations are drilled, the dust from drilling does not enter the drive o Mount the drive to the cabinet backplate using suitable M5 mounting screws o Position the drive, and tighten the mounting screws securely

 When Din Rail Mounting (Frame Size 2 Only)

o Locate the DIN rail mounting slot on the rear of the drive onto the top of the DIN rail first o Press the bottom of the drive onto the DIN rail until the lower clip attaches to the DIN rail o If necessary, use a suitable flat blade screw driver to pull the DIN rail clip down to allow the drive to mount securely on

the rail

o To remove the drive from the DIN rail, use a suitable flat blade screwdriver to pull the release tab downwards, and lift the

bottom of the drive away from the rail first

4.1.2. Grounding Guidelines

The ground terminal of each Optidrive should be individually connected DIRECTLY to the site ground bus bar (through the filter if installed). Optidrive ground connections should not loop from one drive to another, or to, or from any other equipment. Ground loop impedance must confirm to local industrial safety regulations. To meet UL regulations, UL approved ring crimp terminals should be used for all ground wiring connections. The drive Safety Ground must be connected to system ground. Ground impedance must conform to the requirements of national and local industrial safety regulations and/or electrical codes. The integrity of all ground connections should be checked periodically.

4.1.3. Protective Earth Conductor

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

4.1.4. Safety Ground

This is the safety ground for the drive that is required by code. One of these points must be connected to adjacent building steel (girder, joist), a floor ground rod, or bus bar. Grounding points must comply with national and local industrial safety regulations and/or electrical codes.

4.1.5. Motor Ground

The motor ground must be connected to one of the ground terminals on the drive.

4.1.6. 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  The device must be suitable for protecting equipment with a DC component in the leakage current  Individual ELCBs should be used for each Optidrive

Drives with an EMC filter have an inherently higher leakage current to Ground (Earth). For applications where tripping occurs the EMC filter can be disconnected (on IP20 units only) by removing the EMC screw on the side of the product.

The Optidrive product range has input supply voltage surge suppression components fitted to protect the drive from line voltage transients, typically originating from lightning strikes or switching of high power equipment on the same supply.

4.1.7. Shield Termination (Cable Screen)

The safety ground terminal provides a grounding point for the motor cable shield. The motor cable shield connected to this terminal (drive end) should also be connected to the motor frame (motor end). Use a shield terminating or EMI clamp to connect the shield to the safety ground terminal.

4.2. Wiring Precautions

Connect the Optidrive according to section 4.3 and 4.4, 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 4.5 Motor Terminal Box 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.

4.3. Incoming Power Connection

 For a single phase supply, power should be connected to L1/L, L2/N.  For 3 phase supplies power should be connected to L1, L2, and L3. 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 with 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 dimensions according to any local codes or regulations. Guideline dimensions are given in section13.4.  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 13.4. The fuses must comply with any local codes or regulations in place. In general, type gG (IEC 60269) or UL type T fuses are suitable; 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.  An optional Input Choke is recommended to be installed in the supply line for drives where any of the following conditions occur:-

o The incoming supply impedance is low or the fault level / short circuit current is high o The supply is prone to dips or brown outs o An imbalance exists on the supply (3 phase drives) o The power supply to the drive is via a bus-bar and brush gear system (typically overhead Cranes).

 In all other installations, an input choke is recommended to ensure protection of the drive against power supply faults. Refer to

your local Invertek sales partner for available options

 Optidrive HVAC models in frame sizes 4 to 8 are factory fitted with an Input choke as standard.

4.4. 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

utilised, 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.

 For IP55 drives, connect the motor cable screen to the internal ground clamp

Commissioning

6. Commissioning

6.1. General

The following guidelines apply to all applications

6.1.1. Entering the motor nameplate information

Optidrive HVAC 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 HVAC 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 ensure the boiler does not run dry during operation.

6.1.3. Acceleration and Deceleration Ramp Times

Optidrive HVAC units are factory set with acceleration and deceleration ramp rates set to 30 seconds. The default value is suitable for the majority of HVAC 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 HVAC 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 = * will allow the motor to coast to stop (uncontrolled).

6.1.5. Energy Optimiser

The Energy Optimiser attempts to reduce the overall energy consumed by the drive and motor when operating at constant speeds and light loads. The Energy Optimiser is intended for applications where the drive may operate for some periods of time with constant speed and light motor load. P1-06 Energy Optimiser: 0 = Disabled, 1 = Enabled.

6.1.6. 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 voltage boost levels may result in increased motor current and temperature, and force ventilation of the motor may be required. The default value for Voltage boost is set between 0.5 and 2.5%, depending on drive size, and is typically ok for the majority of HVAC applications. P1-11 Voltage Boost: Set as a percentage of motor rated voltage P1-07

7. Parameters

7.1. Parameter Set Overview

The Optidrive HVAC Parameter set consists of 9 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 – HVAC 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 = 10*. 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 = 20*, which allows access to all parameter groups and ranges. Advanced parameter descriptions are listed in the advanced user guide.

8.1. Digital Input Configuration Parameter P1-13

Notes Inputs 1 – 3 are Digital inputs only Inputs 4 & 5 may be used as Analog or Digital inputs, depending on the setting of P1-13 *(*: Logic shown is as per the default setting. Fire mode logic can be configured through parameter P8-09. *(2): Default setting for P1-13 = 1 *(3): When the drive is in PID control (P1-12 = 3) and digital preset reference is selected (P3-05 = 0) then P1-13 can be set to 1, 9, or 10 to

allow selection between two independent digital references using digital input 2. Digital preset reference 1 and 2 are set in P3-06 and P3-15 respectively.

Note: “Motor thermistor trip” connection is via analog input 2 and is configured by parameter P2-33 (). The “External trip” input is no longer utilised for the thermistor input (this is different to the ODP drive and E2 drive).

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

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

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.

25.0

0.0

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.

10.2.2. Modbus Control & Monitoring Registers

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

 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 = *

 Registers 6 to 24 can be read regardless of the setting of P1-12

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  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.

Note

 The maximum motor cable length stated applies to using a shielded motor cable. When using an unshielded cable, the maximum cable

length limit may be increased by 50%. When using the Invertek Drives recommended output choke, the maximum cable length may be increased by 100%

 The PWM output switching from any inverter when used with a long motor cable length can cause an increase in the voltage at the

motor terminals, depending on the motor cable length and inductance. The rise time and peak voltage can affect the service life of the motor. Invertek Drives recommend using an output choke for motor cable lengths of 50m or more to ensure good motor service life

 For UL compliant installation, use Copper wire with a minimum insulation temperature rating of 70°C, UL Class CC or Class J Fuses

11.1. Environmental

Ambient temperature range Operational : -10 … 50C (refer to section 11.5.1 on page 50 for derating information) Storage : -40 C … 60 C Max altitude for rated operation : 1000m (refer to section 11.5.2 on page 50 for derating information) Relative Humidity : < 95% (no condensation permitted)

11.2. Input Voltage Ranges

Depending upon model and power rating, the drives are designed for direct connection to the following supplies:

All Optidrive HVAC units have phase imbalance monitoring. A phase imbalance of > 3% will result in the drive tripping. For input supplies which have supply imbalance greater than 3% (typically the Indian sub- continent & parts of Asia Pacific including China) Invertek Drives recommends the installation of input line reactors. Alternatively, the drives can be operated as a single phase supply drive with 50% derating.

11.3. Output Power and Current ratings

The following tables provide the output current rating information for the various Optidrive HVAC models. Invertek Drives always recommend that selection of the correct Optidrive is based upon the motor full load current at the incoming supply voltage.

11.5. Derating Information

Derating of the drive maximum continuous output current capacity is require when

 Operating at ambient temperature in excess of 40°C / 104°F  Operating at Altitude in excess of 1000m/ 3281 ft  Operation with Effective Switching Frequency higher than the minimum setting

The following derating factors should be applied when operating drives outside of these conditions

11.5.1. Derating for Ambient Temperature

11.5.2. Derating for Altitude

11.5.3. Derating for Switching Frequency

11.5.4. Example of applying Derating Factors

A 4kW, IP66 drive is to be used at an altitude of 2000 metres above sea level, with 12 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, 12 kHz, 25% derating

9.5 Amps x 75% = 7.1 Amps Now, apply the derating for higher ambient temperature, 2.5% per °C above 40°C = 5 x 2.5% = 12.5%

7.1 Amps x 87.5% = 6.2 Amps Now apply the derating for altitude above 1000 metres, 1% per 100m above 1000m = 10 x 1% = 10%

7.9 Amps x 90% = 5.5 Amps continuous current available. If the required motor current exceeds this level, it will be necessary to either

- Reduce the switching frequency selected

- Use a higher power rated drive and repeat the calculation to ensure sufficient output current is available.
