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

3.4. 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
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.
Protective Earth Conductor
The Cross sectional area of the PE Conductor must be at least equal to that of the incoming supply conductor.
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.
Motor Ground
The motor ground must be connected to one of the ground terminals on the drive.
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.
Power & Control Wiring
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.
4.3. Incoming Power Connection
4.3.1. Cable Selection
For 1 phase supply, the mains power cables should be connected to L1/L, L2/N.
For 3 phase supplies, the mains power cables should be connected to L1, L2, and L3. Phase sequence is not important.
For compliance with CE and C Tick EMC requirements, refer to section 4.10 EMC Compliant Installation on page 14.
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 dimensioned according to any local codes or regulations. Maximum dimensions are given in section 9.2.
Rating Tables.
4.3.2. Fuse / Circuit Breaker Selection
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 9.2. Rating Tables. The fuses must comply with any local codes or regulations in place. In general, type gG (IEC
60269) or UL type J 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.
The maximum permissible short circuit current at the Optidrive Power terminals as defined in IEC60439-1 is 100kA.

Version 2.00 | Optidrive ODE-3 User Guide | 15www.invertekdrives.com
Page 16
4.3.3. Optional Input Choke
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 busbar 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. Part numbers
are shown in the table.
4.4. 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
Power & Control Wiring
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.
Maximum permitted motor cable length for all models: 100 metres shielded, 150 metres unshielded.
Where multiple motors are connected to a single drive using parallel cables, an output choke must be installed.

4.6. 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.

Motor Energy Optimisation is intended for use in applications where the motor operates for extended time periods at constant speed
with light load. It should not be used in applications with large, sudden step changes in load or for PI control applications.
Optidrive Energy Optimisation reduces the drive internal heat losses increasing efficiency however it may result in some vibration in the
motor during light load operation. In general, this function is suited to Fan, Pump and Compressor applications.

= Uni-polar 0 to 10 Volt Signal. The drive will remain at minimum speed (P-02) if the analog reference after scaling and
offset are applied is =<0.0%. 100% signal means the output frequency / speed will be the value set in P-01.

Adjustable threshold level used in conjunction with settings 4 to 8 of P-18.
Preset Speeds / Frequencies selected by digital inputs depending on the setting of P-15.
If P-10 = 0, the values are entered as Hz. If P-10 > 0, the values are entered as RPM.
NOTE Changing the value of P-09 will reset all values to factory default settings.
This parameter allows a 2nd ramp time to be programmed into the drive.
This ramp time is automatically selected in the case of a mains power loss if P-05 = 2 or 3. When set to 0.00, the drive will coast to
stop.
When using a setting of P-15 that provides a “Fast Stop” function, this ramp time is also used.
In addition, if P-24 > 0, P-02 > 0, P-26=0 and P-27 = P-02, this ramp time is applied to both acceleration and deceleration when
operating below minimum speed, allowing selection of an alternative ramp when operating outside of the normal speed range,
which may be useful in pump and compressor applications.

The Skip Frequency function is used to avoid the Optidrive operating at a certain output frequency, for example at a frequency
which causes mechanical resonance in a particular machine. Parameter P-27 defines the centre point of the skip frequency band,
and is used in conjunction with P-26. The Optidrive output frequency will ramp through the defined band at the rates set in P-03 and
P-04 respectively, and will not hold any output frequency within the defined band. If the frequency reference applied to the drive is
within the band, the Optidrive output frequency will remain at the upper or lower limit of the band.

0: DC Injection on Stop. DC is injected into the motor at the current level set in P-59 following a stop command, after the output
frequency has reduced to P-58 for the time set in Index 1.
NOTE If the drive is in Standby Mode prior to disable, the DC injection is disabled
1: DC Injection on Start. DC is injected into the motor at the current level set in P-59 for the time set in Index 1 immediately after
the drive is enabled, prior to the output frequency ramping up. The output stage remains active during this phase. This can be used to
ensure the motor is at standstill prior to starting.
2: DC Injection on Start & Stop. DC injection applied as both settings 0 and 1 above.
0: Disabled
1: Enabled. When enabled, on start up the drive will attempt to determine if the motor is already rotating, and will begin to control
the motor from its current speed. A short delay may be observed when starting motors which are not turning.
2: Enabled on Trip, Brown Out or Coast Stop. Spin start is only activated following the events listed, otherwise it is
disabled.
0: Disabled
1: Enabled With Software Protection. Brake chopper enabled with software protection for a 200W continuous rated
resistor.
2: Enabled Without Software Protection. Enables the internal brake chopper without software protection. An external
thermal protection device should be fitted.
3: Enabled With Software Protection. As setting 1, however the Brake Chopper is only enabled during a change of the
frequency setpoint, and is disabled during constant speed operation.
4: Enabled Without Software Protection. As setting 2, however the Brake Chopper is only enabled during a change of the
frequency setpoint, and is disabled during constant speed operation.
Analog Input 1 Scaling. The analog input signal level is multiplied by this factor, e.g. if P-16 is set for a 0 – 10V signal, and the
scaling factor is set to 200.0%, a 5 volt input will result in the drive running at maximum frequency / speed (P-01).
Slave Speed Scaling. When operating in Slave Mode (P-12 = 9), the operating speed of the drive will be the Master speed
multiplied by this factor, limited by the minimum and maximum speeds.

7. Analog and Digital Input Macro Configurations
7.1. Overview
Optidrive E3 uses a Macro approach to simplify the configuration of the Analog and Digital Inputs. There are two key parameters
which determine the input functions and drive behaviour:
P-12 Selects the main drive control source and determines how the output frequency of the drive is primarily controlled.
P-15 Assigns the Macro function to the analog and digital inputs.
Additional parameters can then be used to further adapt the settings, e.g.
P-16 Used to select the format of the analog signal to be connected to analog input 1, e.g. 0 – 10 Volt, 4 – 20mA.
P-30 Determines whether the drive should automatically start following a power on if the Enable Input is present.

7.7. 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 a normally open (Close to Activate Fire Mode) or Normally Closed
(Open to Activate Fire Mode) according to the setting of P-30 Index 2. In addition, the input may be momentary or maintained type,
selected by P-30 Index 3.
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 that building.
The fire mode function is enabled when P-15 = 15, 16 or 17, with Digital Input 3 assigned to activate fire mode.
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).

Mechanical Installation Requirements
All Optidrive E3 units are intended for indoor installation within controlled environments which meet the condition limits shown in section 9.1. Environmental.
The drive can be operated within an ambient temperature range as stated in section 9.1. Environmental.
For IP20 units, installation is required in a pollution degree 1 environment.
For IP66 (Nema 4X) units, installation in a pollution degree 2 environment is permissible.
Frame size 4 drives must be mounted in an enclosure in a manner that ensures the drive is protected from 12.7mm (1/2 inch) of deformation of the
enclosure if the enclosure impacted.
Electrical Installation Requirements
Incoming power supply connection must be according to section 4.3. Incoming Power Connection.
Suitable Power and motor cables should be selected according to the data shown in section 9.2. Rating Tables and the National Electrical Code
or other applicable local codes.
Motor Cable 75°C Copper must be used.
Power cable connections and tightening torques are shown in sections 3.3. Mechanical Dimensions and Mounting – IP20 Open Units and 3.5.
Mechanical Dimensions – IP66 (Nema 4X) Enclosed Units.
Integral Solid Sate short circuit protection does not provide branch circuit protection. Branch circuit protection must be provided in accordance
with the national electrical code and any additional local codes. Ratings are shown in section 9.2. Rating Tables
Transient surge suppression must be installed on the line side of this equipment and shall be rated 480Volt (phase to ground), 480 Volt (phase to
phase), suitable for over voltage category iii and shall provide protection for a rated impulse withstand voltage peak of 4kV.
UL Listed ring terminals / lugs must be used for all bus bar and grounding connections.
General Requirements
Optidrive E3 provides motor overload protection in accordance with the National Electrical Code (US).
• Where a motor thermistor is not fitted, or not utilised, Thermal Overload Memory Retention must be enabled by setting P-50 = 1.
•
Where a motor thermistor is fitted and connected to the drive, connection must be carried out according to the information shown in section
4.9.2. Motor Thermistor Connection.
Technical Data
9.5. EMC Filter Disconnect
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 completely removing the EMC screw on the side of the product.
Remove the screw as indicated right.
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.
When carrying out a HiPot (Flash) test on an installation in which the drive is built, the
9
voltage surge suppression components may cause the test to fail. To accommodate this
type of system HiPot test, the voltage surge suppression components can be disconnected by
removing the VAR screw After completing the HiPot test, the screw should be replaced and
the HiPot test repeated. The test should then fail, indicating that the voltage surge suppression
components are once again in circuit.
380 – 480 Volts for 400 Volt rated units, + / - 10% variation allowed, Maximum 500 Volts RMS.
All Optidrive E3 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.
Voltage Rating Min kW (HP) Max kW (HP) Maximum supply
