In the parameter list below, it is assumed that all other parameters and switches remain at their default setting.
The following must be programmed in the order shown - see an explanation of the settings in the Programming Guide.
Function
Par. no.
Setting
1) Make sure the motor runs properly. Do the following:
Set the motor parameters using nameplate data
1-2*
As specified by motor nameplate
Have the adjustable frequency drive makes an Automatic Mo-
tor Adaptation
par. 1-29
Automatic
Motor Adaptation
(AMA)
[1] Enable complete AMA
2) Check that the motor is running and the encoder is attached properly. Do the following:
Press the “Hand On” LCP key. Make sure the motor is running
and note in which direction it is turning (henceforth referred
to as the “positive direction”).
Set a
positive
reference.
Go to par. 16-20
Motor Angle
. Turn the motor slowly in the
positive direction. It must be turned so slowly (only a few
RPM) that it can be determined if the value in
par. 16-20
Motor Angle
is increasing or decreasing.
par. 16-20
Motor An-
gle
N.A. (read-only parameter) Note: An increasing value overflows
at 65535 and starts again at 0.
If par. 16-20
Motor Angle
is decreasing, then change the en-
coder direction in par. 5-71
Term 32/33 Encoder Direction
.
par. 5-71
Term
32/33 Encoder Di-
rection
[1] Counter clockwise (if par. 16-20
Motor Angle
is decreasing)
3) Make sure the drive limits are set to safe values
Set acceptable limits for the references.

5) Configure and scale the reference to the Speed Control
Set up Analog Input 53 as a reference source
par. 3-15
Reference
Resource 1
Not necessary (default)
Scale Analog Input 53 0 RPM (0 V) to 1500 RPM (10V)
6-1*
Not necessary (default)
6) Configure the 24V HTL encoder signal as feedback for the Motor Control and the Speed Control
Set up digital input 32 and 33 as encoder inputs
par. 5-14
Terminal
32 Digital Input
par. 5-15

33 Digital Input
[0] No operation (default)
Choose terminal 32/33 as motor feedback
par. 1-02

Not necessary (default)
Choose terminal 32/33 as Speed PID feedback
par. 7-00
Speed PID

Not necessary (default)
7) Tune the Speed Control PID parameters
Use the tuning guidelines when relevant or tune manually
7-0*
See the guidelines below
8) Finished!
Save the parameter setting to the LCP for safe keeping
