Invertek Drives ODV-42075-IN [13/24] Changing parameters
6.1.1. Changing Parameters
To change a parameter value press and hold the key for >1s whilst the drive displays SToP. The display changes to P-01,
indicating parameter 01. Press and release the
key to display the value of this parameter. Change to the required value using the
and keys. Press and release the key once more to store the change. Press and hold the key for >1s to return to real-time
mode. The display shows
SToP if the drive is stopped or the real-time information (e.g. speed) if the drive is running.
6.1.2. Reset Factory Default Settings
To reset factory default parameters, press , and for >2s. The display shows ìP-dEFî. Press the button to acknowledge and
reset the drive.
6.2. Terminal Control
When delivered, the Optidrive is in the factory default state, meaning that it is set to operate in terminal control mode and all
parameters (P-xx) have the default values as indicated in section
7 Parameters.
1. Connect motor to drive, checking star/delta connection for the voltage rating
2. Enter motor data from motor nameplate, P-07 = motor rated voltage, P-08 = motor rated current, P-09 = motor rated
frequency.
3. Connect a control switch between the control terminals 1 and 2 ensuring that the contact is open (drive disabled).
4. Connect a potentiometer (1k min to 10 k max) between terminals 5 and 7, and the wiper to terminal 6.
5. With the potentiometer set to zero, switch on the supply to the drive. The display will show
StoP.
6. 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.
7. 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 50Hz (
H 50.0) at max speed.
8. To display motor current (A), briefly press the (Navigate) key.
9. Press again to return to speed display.
10. 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 with the enable/disable closed the display will show
H 0.0 (0.0Hz), if left like this for 20 seconds the drive will go into
standby mode, display shows
Stndby, waiting for a speed reference signal.
6.3. Keypad Control
To allow the Optidrive to be controlled from the keypad in a forward direction only, set P-12 =1:
1. Connect Motor as for terminal control above.
2. Enable the drive by closing the switch between control terminals 1 & 2. The display will show StoP.
3. Press the
key. The display shows H 0.0.
4. Press
to increase speed.
5. 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
StoP 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
& keys to adjust as required then press the key to return the display to StoP.
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:
11. Operation is the same as when P-12=1 for start, stop and changing speed.
12. Press the key. The display changes to H 0.0.
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 the speed set in P-01.
15. To reverse the direction of rotation of the motor, press the
key again.
