Par. no.
Setting
1) Make sure the motor runs properly. Do the following:
Set the drive to control the motor based on
drive output frequency.
0-02
Hz
[1]
Set the motor parameters using nameplate
data.
1-2*
As specified by motor name plate
Run Automatic Motor Adaptation.
1-29
Enable complete AMA
[1] and then run the
AMA function.
2) Check that the motor is running in the right direction.
Press the “Hand On” LCP key and the ^ key
to make the motor turn slowly. Check that
the motor runs in the correct direction.
If the motor runs in the wrong direction,
remove power temporarily and reverse
two of the motor phases.
3) Make sure the frequency converter limits are set to safe values
Check that the ramp settings are within ca-
pabilities of the drive and allowed applica-
tion operating specifications.

Depends on motor/load size!
Also active in Hand mode.
Prohibit the motor from reversing (if nec-
essary)

4) Configure the feedback to the PID controller.
Set up Analog Input 54 as a feedback input. 20-00
Analog input 54
[2] (default)
Select the appropriate reference/feedback
unit.
20-12

5) Configure the setpoint reference for the PID controller.
Set acceptable limits for the setpoint refer-
ence.
3-02
3-03
-5 °C
35 °C
Set up Analog Input 53 as Reference 1
Source.
3-15
Analog input 53
[1] (default)
6) Scale the analog inputs used for setpoint reference and feedback.
Scale Analog Input 53 for the temperature
range of the potentiometer (-5 to +35°C,
0-10 V).
6-10
6-11
6-14
6-15
0 V
10 V (default)
-5 °C

Scale Analog Input 54 for the temperature
range of the temperature sensor (-10 to
+40°C, 4-20 mA)
6-22
6-23
6-24
6-25
4 mA
20 mA (default)
-10 °C
40 °C
7) Tune the PID controller parameters.
Select inverse control because motor’s
speed should increase when the feedback
is greater than the setpoint reference.
20-81
Inverse
[1]
Adjust the drive’s Closed Loop Controller, if
needed.
20-93

See Optimization of the PID Controller,
below.
8) Finished!
Save the parameter setting to the LCP for
safe keeping
