TROUBLESHOOTING
TO CLEAR A TRIP CONDITION Remove the condition which caused the trip and press the STOP
key or re-enable the drive. The drive will restart according to the mode selected by P-30.If the motor is stopped and
the display shows STOP, there is no fault; the drive output is disabled and the drive is ready to run.
Fault
Code What has happened What to do
P-deF Default parameters loaded Press STOP key, drive is ready to configure for particular
application
O-I
Over current on drive
output.
Excess load on the motor.
Over temperature on the
heatsink
Motor at constant speed: investigate overload or
malfunction. Motor starting: load stalled or jammed.
Check for star-delta motor wiring error.
Motor accelerating/decelerating: The accel/decel time too
short requiring too much power. If P-03 or P-04 cannot
be increased, a bigger drive is needed
O-Uolt Over voltage on DC bus Supply problem, or increase decel ramp time P-04.
U-Uolt Under voltage on DC bus This occurs routinely when power is switched off. If it
occurs during running, check power supply voltage.
I.t-trP
The drive has tipped on
overload after delivering
greater than 100% load for a
period of time.
Check to see when the decimal points are flashing (drive
in overload) and either decrease acceleration rate or
load. Check cable length is within specification.
th-Flt Faulty thermistor on
heatsink. Refer to your IDL Authorised Distributor.
E-triP External trip (on dig. input 2
or 3) External trip on digital input – see P-19 (motor thermistor?)
EE-F EEPROM fault. Parameters not saved, defaults
reloaded.
Try again. If problem recurs, refer to your IDL Authorised
Distributor.
PS-Trp Internal power stage fault
Check wiring to motor, look for ph-ph or ph-Earth short
circuit.
Check drive ambient temp, additional space or cooling
needed?
Check drive is not forced into overload.
O-t Heatsink over temperature Check drive ambient temp. Additional space or cooling
needed?
Iin-F Current analog input out of
range Check input current in range defined by P-16

V
oltage / Frequency (V/f) Characteristic
The V/f characteristic is defined byseveral parameters asshown.
Reducing the voltage at a particular frequency reduces the current in
the motor and hence the torque and power; for fans and certain types
of pump which require very little torque at low speed use fan/ pump
curve, P-06=1, HVAC.
The V/f curve can be further modified by using P-26 and P-29,where
P-26 determines the percentage increaseor decrease of the voltage
applied to the motor at the frequency specified in P-29. This can be
useful if motor instability is experiencedat certain frequencies,if this
is the case increase or decrease the voltage (P-26) at the speed of
instability (P-29).

BASICS + GETTING STARTED
MOTOR TERMINAL BOX CONNECTIONS
Motors are connected in either STAR or DELTA. The motor
rating plate will indicate the voltage rating for the method
of connection, ensure that this matches the Optidrive
operating voltage.
CONTROL TERMINAL BLOCK -
Default Status
WARNING !
The STOP function does not remove potentially lethal high voltages. ISOLATE the drive and
wait 10 minutes before starting anywork on it
Parameter P-01 can be set to operate the motor at up to 60,000 rpm, hence use this
parameter with care
If it is desired to operate the drive at any frequency/speed above the rated speed (P-09/ P-10)
of the motor, consult the manufacturers of the motor and the driven machine about suitability
for over-speed operation
The fan (if fitted) to the heatsink of the Optidrive starts automatically when the heatsink
temperature reaches approximately 40ºC. When the heatsink is at room temperature the fan
will be stopped.
MECHANICAL INSTALLATION
Optidrives can be installed side-by-side with their heatsink
flanges touching. This gives adequate ventilation space between
them. If the Optidrive is to be installed above another drive or
any other heat-producing device, the minimum vertical spacing
is 100mm. The enclosure should either be force-ventilated or
large enough to allow natural cooling (allow 0.1 m3per kW of
drive rating).
GROUNDING (EARTHING)
The ground terminal of each Optidrive should be individually
connected DIRECTLY to the site earth (ground) busbar (through
the filter if installed) as shown. Optidrive ground connections
should not loop from one drive to another, or to, or from any
other equipment. Ground loop impedance must conform to local
industrial safety regulations. To meet UL regulations, UL
approved ring crimp terminals should be used for all earth wiring
connections.
EASY START-UP
When delivered, the Optidrive is in the default state,
meaning that it is set to operate in terminal mode and
all parameters (P-xx) have the default values as
shown overleaf.
Connect a control switch between the control
terminals 1 and 2.
Connect a potentiometer (500 Ω min to 10 k Ω max)
between terminals 5 and 7, and wiper to terminal6.
Set the control switch between pins 1 and 2 open
so that the drive is ‘disabled’.
With the potentiometer set to zero, switch on the
supply to the drive. The display will show StoP.
Close the control switch, terminals 1-2. The drive is
now ‘enabled’ and the output frequency/speed are
controlled by the potentiometer. The display shows
zero speed in Hz (H 0.0) with the potentiometer
turned to minimum.
Turn the potentiometer to maximum. The motor will
accelerate to 50Hz (the default value of P-01) under
the control of the accelerating ramp time P-03. The
display shows H 50.0 (50Hz) at max speed.
To display motor current (A), briefly press the
Navigate key ⇔ .
Press ⇔ again to return to speed display.
To stop the motor, either turn the potentiometer back
to zero or disable the drive by opening the control
switch (terminals 1-2).
If the enable/disable switch is opened the drive will
decelerate to stop at which time the display will show
StoP. If the potentiometer is turned to zero and the
enable/disable is closed the display will show 0.0Hz, if
left like this for 20 seconds the drive will go into
standby mode, display shows Stndby, waiting for a
speed reference.

IMPORTANT SAFETY INFORMATION
Safety of machinery, and safety-critical applications
Optidrive hardware and software are designed and tested to a high standard and failures are
unlikely. Electromagnetic Compatibility (EMC)
Optidrive is designed to high standards of EMC. EMC data is provided in a separate EMC
Data Sheet, available on request. Under extreme conditions, the product might cause or
suffer disturbance due to electromagnetic interaction with other equipment. It is the
responsibility of the installer to ensure that the equipment or system into which the product
is incorporated complies with the EMC legislation of the country of use. Within the European
Union, equipment into which this product is incorporated must comply with 89/336/EEC,
Electromagnetic Compatibility.
When installed as recommended in this User Guide, the radiated emissions levels of all
Optidrives are less than those defined in the Generic radiated emissions standard EN61000-
6-4. When correctly fitted with an Optifilter (Mains filter), the conducted emission levels are
less than those defined in the Generic radiated emissions standard EN61000-6-3 (class B)
for screened cable lengths of < 5m and with EN61000-6-4 (class A) for screened cable
lengths of < 25m.
SIMPLE PARAMETER ADJUSTMENTS
The factory-set default parameter values may give satisfactory
performance, however certain adjustments may be beneficial.
Maximum and Minimum Speeds P-01 & P-02
Set P-01 to the maximum speed and P-02 to the minimum speed for
your application. These limits are mirrored for negative speeds. If a
non-zero minimum speed is set in P-02, the motor will ramp (P-03) to
this minimum speed as soon as the drive is enabled.
Acceleration and Deceleration P-03 & P04
Ramps which are too short will cause the drive to deliver currents in
excess of full load current and may result in it tripping out or the
motor stalling
Stop Mode P-05
Select method of stopping required when drive is disabled. Ramp to
stop (P-05 = 0) decelerates the motor at the rate set by deceleration
ramp time P-04. Freewheel/ Coast to stop (P-05=1) disables the drive
output immediately, allowing the motor to decelerate naturally due
to friction or under the control of a mechanical brake
Torque/Speed Characteristic P-06
Certain loads such as fans and centrifugal pumps need very little
torque at low speed. Set P-06=1 to reduce power loss at low speeds
for this load type.
Rated Current, Rated Frequency and Rated Speed P-08, P-09, P-10.
Parameters P-08 and P-09 should to be set to correspond with the
rated current and frequency shown on the motor rating plate.
Parameter P-10 is optional. If this parameter is set to zero (default
state), speed will be displayed in Hz; if speed indication is required
in rpm, enter the motor rated speed (speed at full load) from the
motor rating plate.
Voltage Boost P-11
Any load which is ‘sticky’ to start will benefit from a voltage boost
on starting. P-11 permits a boost of up to 25% of full motor voltage
to be applied.
NOTE: Use of this parameter increases motor heating at low speeds
Terminal or Keypad Control P-12
Terminal control (P-12=0) is used when the drive needs to be
controlled from some remote point, such as a control panel
interface or machine system.
Keypad control (P12=1 or 2) is used for local, manual control and
commissioning
Extended Parameter Set P15 to P-40 and P-00
The Extended Parameter Set is intended for use by specialist drives
engineers and technicians and will not generally be required for
simple applications.
PARAMETER ZERO
•Provides a read only window into the motor control software
allowing

Connection – When
connecting the choke
observe the following :-
i) The order of the input
phases (L1,L2,L3) is not
important.
ii) The choke can be
mounted to suit the wiring,
either above the drive or
anywhere in the panel.
Either set of terminals can
be used for the Input or
Output.
iii) The choke should NOT
be connected directly to the
