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 m
drive rating).

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.

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 kΩ max)

between terminals 5 and 7, and wiper to terminal 6.

 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

speed reference.

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
