Function Par. no. Setting
Initialize the frequency converter 14-22 [2] Initialization - make a power cycling - press reset
1) Set motor parameters:
Set the motor parameters according to name plate
data
1-2* As stated on motor name plate
Perform a full Automation Motor Adaptation 1-29 [1] Enable complete AMA
2) Check that motor is running in the right direction.
When motor is connected to frequency converter with straight forward phase order as U - U; V- V; W - W motor shaft usually turns
clockwise seen into shaft end.
Press “Hand On” LCP key. Check shaft direction by
applying a manual reference.
If motor turns opposite of required direction:
1. Change motor direction in 4-10 Motor Speed
Direction
2. Turn off mains - wait for DC link to discharge -
switch two of the motor phases
4-10 Select correct motor shaft direction
Set configuration mode 1-00 [3] Process
Set Local Mode Configuration 1-05 [0] Speed Open Loop
3) Set reference configuration, ie. the range for reference handling. Set scaling of analog input in par. 6-xx
Set reference/feedback units
Set min. reference (10

If set value is determined from a preset value
(array parameter), set other reference sources to

4) Adjust limits for the frequency converter:
Set ramp times to an appropriate value as 20 s
3-41
3-42 20 s

Set min. speed limits
Set motor speed max. limit
Set max. output frequency 4-11

4-19 300 RPM
1500 RPM
60 Hz
Set S201 or S202 to wanted analog input function (Voltage (V) or milli-Amps (I))
NOTE
Switches are sensitive - Make a power cycling keeping default setting of V
5) Scale analog inputs used for reference and feedback
Set terminal 53 low voltage
Set terminal 53 high voltage
Set terminal 54 low feedback value
Set terminal 54 high feedback value
Set feedback source
