have the default values as indicated in section 6 Parameters.
1.
Connect the drive and motor according to the connection diagram shown at the beginning of this User Guide
2.
Enter motor data from motor nameplate, P-07 = motor rated voltage, P-08 = motor rated current, P-09 = motor rated frequency.
3.
With the potentiometer set to zero, switch on the supply to the drive. The display will show
.
4.
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 (
.
) with the potentiometer turned to minimum.
5.
Turn the potentiometer to maximum. The motor will accelerate to 50Hz (the default value of P-01) under the control of the

The drive will run forward, increasing speed until
is released. The rate of acceleration is controlled by the setting of P-03, check this
before starting.
6.
Press
to decrease speed. The drive will decrease speed until
is released. The rate of deceleration is limited by the setting in P-
04
7.
Press the
key. The drive will decelerate to rest at the rate set in P-04.
8.
The display will finally show
at which point the drive is disabled
9.
To preset a target speed prior to enable, press the
key whilst the drive is stopped. The display will show the target speed, use the

.
10.
Pressing the
key will start the drive accelerating to the target speed.
To allow the Optidrive to be controlled from the keypad in a forward and reverse direction, set P-12 =2:

Operation is the same as when P-12=1 for start, stop and changing speed.
12.
Press the
key. The display changes to
.
.
13.
Press
to increase speed
14.
The drive will run forward, increasing speed until
is released. Acceleration is limited by the setting in P-03. The maximum speed is
