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

3.1.9. Cold-plate Capacity Calculation
The coldplate variants of the Optidrive Coolvert are designed to be mounted to a metallic, heat conducting surface, removing the
heat generated as losses within the drive. Thermostrate or heat transfer compound must be added to ensure optimal heat transfer and
minimum thermal resistance.
In order to ensure that the drive remains within the design temperatures, the following information should be considered when
designing the system:
Select the desired PWM operating frequency from the available options in Parameter P5-06
Determine the maximum permissible drive temperature, TMAX from table X below
Calculate the motor absorbed electrical power, PMOT, based on the motor rated voltage, current and efficiency
PMOT = √3 * Rated Voltage * Rated Current * Power Factor * Efficiency
Calculate the losses in the drive, PLOSS, based on the required motor power
PLOSS = PMOT * (1 - Drive Efficiency)
Typical drive efficiency values are shown in the table below for each available effective switching frequency:

3.2.2. Grounding Guidelines
The ground terminal of each Optidrive Coolvert should be individually connected DIRECTLY to the site ground bus bar (through the
filter if installed). Optidrive Coolvert 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 greater than 3.5mA to earth can exist. The Optidrive Coolvert 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 (or B+) 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 Coolvert as opposed to one protection device serving many.
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.
3.3. EMC Compliant Installation
The Optidrive Coolvert is designed in compliance with stringent EMC standards. All models are supplied with an internal EMC
filter, which is specifically designed to reduce the emissions in conformity with harmonised European Standards. It is the installer’s
responsibility that the device or system within which the Optidrive Coolvert is incorporated, is in compliance with the Standards in
force in the country of use. The relevant EMC directive in force in the European Union is the EMC 2014/30/EU.
The Optidrive Coolvert is intended to be incorporated inside fixed installation devices, only installed by skilled individuals. Conformity
with the EMC Standard can only be achieved if the guidance provided in this chapter is strictly adhered to.
NOTE It is the responsibility of the installer to ensure that the final product containing the Optidrive Coolvert complies with any
standard necessary for that final product.

Installation
General
1Compliance with category C1 conducted emissions only is achieved. To ensure compliance with category C2 radiated emissions
with the single phase 230V PFC drives, it is necessary to install a ferrite core (e.g. Fair-Rite round cable snap ferrite 0431176451),
one around the supply cable and the second around the supply earth.
Supply Cable
2A 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.
3A 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.
Motor Cable
4
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.
5The 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.
Control Cable
6A shielded cable with low impedance shield. Twisted pair cable is recommended for analogue signals.
3.3.2. Incoming Power Connection
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 3.3. 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 6.2.
Detailed Product Rating Tables on page 44.
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 6.2. Detailed Product 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.
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.
Maximum permitted motor cable length for all models: 10 metres shielded, 20 metres unshielded.

3.3.4. Safe Torque Off
Safe Torque OFF will be referred to as “STO” through the remainder of this section. If the “STO” function is not required in your
installation, you must link out the “STO” circuit by linking terminal 4 to terminal 8 and linking terminal 7 to terminal 9 as shown in the
figure below. Please read the remainder of this chapter for further information about the functionality and limitations of the “STO” circuit.

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.
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 8 with respect to Terminal 9), this allows the drive to be incorporated into a complete safety control system
where “STO“ requirements need to be fulfilled.1The “STO“ function can typically eliminate the need for electro-mechanical contactors
with cross-checking auxiliary contacts as per normally required to provide safety functions.2The drive has the “STO“ function built-in as
standard and complies with the definition of “Safe torque off“ as defined by IEC 61800-5- 2:2016. 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 fail-safe 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.

EN 62061: 2005 & A2: 2015 SIL CL 3
Independent Approval TUV Rheinland
What STO Does Not Provide
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.
1 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).
2 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).

Installation
“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 P1-11) 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.
To get the drive out of “Safe Torque Off” mode then any “Fault messages” need to be reset and the drive “STO” input needs to be
re-energised.
“STO” Status and Monitoring
There are a number of methods for monitoring the status of the “STO” input, these are detailed below:
 Optional Remote Keypad
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” on the remote keypad and bit 5 of the status word will become active.
NOTE If the drive is in a tripped condition then the relevant trip will be displayed on the remote keypad and not “InHibit”.
 Drive Output Relay
Drive relay 1: Setting P3-05 to a value of “5” will result in relay opening when the “STO” function is activated.
“STO” Fault Code
Fault Code Code Number Description Corrective Action
“Sto-F” 29 A fault has been detected within either of the
internal channels of the “STO” circuit.
Refer to your Invertek Sales
Partner
“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.
“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 3.3. EMC Compliant Installation on page 14 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
24V dc on the drive or from an External 24V dc power supply.
