Function
Parameter
Setting
Initialize the frequency converter.
Parameter 14-22 Operati
on Mode
[2] Initialization
1. Perform a power cycling.
2. Press [Reset].
1) Set motor parameters:
Set the motor parameters according to the
nameplate data.
Parameter group 1-2*
Motor Data
As stated on motor nameplate.
Perform automatic motor adaptation (AMA).
Parameter 1-29 Automa
tic Motor Adaptation
(AMA)
[1] Enable complete AMA
2) Check that motor is running in the right direction.
When the motor is connected to frequency converter with straight forward phase order as U - U; V- V; W - W, the motor shaft usually
turns clockwise as viewed from the shaft end.
Press the [Hand On] LCP key. Check the shaft direction by applying a manual reference.
If the motor turns opposite of the required
direction:
1. Change motor direction in
parameter 4-10 Motor Speed Direction
.
2. Turn off mains - wait for DC link to
discharge - switch 2 of the motor
phases.
Parameter 4-10 Motor
Speed Direction
Select correct motor shaft direction.
Set configuration mode.
Parameter 1-00 Configu-
ration Mode
[3] Process
Set local mode configuration.
Parameter 1-05 Local
Mode Configuration
[0] Speed Open Loop
3) Set reference configuration,
that is,
the range for handling of references. Set scaling of analog input in parameter group 6-**
Analog In/Out.
Set reference/feedback units:
Set minimum reference (10
°
C (50
°
F)):
Set maximum reference (80
°
C (176
°
F)):
If set value is determined from a preset
value (array parameter), set other reference
sources to No function.

Set S201 or S202 to desired analog input function (Voltage (V) or milliamps (I)):
NOTICE
Turn off the frequency converter before moving the switches from one setting to another. Use finger to gently move
the switches.
5) Scale analog inputs used for reference and feedback
