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 order shown - see explanation of settings in the Programming Guide.
Function
Par. no.
Setting
1) Make sure the motor runs properly. Do the following:
Set the motor parameters using name plate data
P-02 to P-07
F-04 & F-05
As specified by motor name plate
Have the frequency converter makes an auto tune
Par. P-04
Auto Tune
[1] Enable complete auto tune
2) Check the motor is running and the encoder is attached properly. Do the following:
Press the “Hand” Keypad key. Check that 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. DR-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. DR-20
Motor Angle
is increasing
or decreasing.
Par. DR-20
Motor An-
gle
N.A. (read-only parameter) Note: An increasing value overflows at
65535 and starts again at 0.
If par. DR-20
Motor Angle
is decreasing then change the encoder
direction in par. E-81
Term 32/33 Encoder Direction
.
Par. E-81
Term 32/33
Encoder Direction
[1] Counter clockwise (if par. DR-20

is decreasing)
3) Make sure the drive limits are set to safe values
Set acceptable limits for the references.

Check that the ramp settings are within drive capabilities and
allowed application operating specifications.

5) Configure and scale the reference to the Speed Control
Set up Analog Input 53 as a reference Source
Par. F-01
Frequency
Setting 1
Not necessary (default)
Scale Analog Input 53 0 RPM (0 V) to 1500 RPM (10V)
AN-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. E-05
Terminal 32
Digital Input
par. E-06
Terminal 33
Digital Input
[0] No operation (default)
Choose terminal 32/33 as motor feedback
Par. H-42

Feedback Source
Not necessary (default)
Choose terminal 32/33 as Speed PID feedback
Par. PI-00
Speed PID
Feedback Source
Not necessary (default)
7) Tune the Speed Control PID parameters
Use the tuning guidelines when relevant or tune manually
PI-0#
See the guidelines below
8) Finished!
Save the parameter setting to the Keypad for safe keeping
Par. K-50

Copy
[1] All to Keypad
3.4.2 Tuning PID Speed Control
The following tuning guidelines are relevant when using one of the Flux motor control principles in applications where the load is mainly inertial (with a low amount
of friction).
The value of par. PI-02
Speed PID Proportional Gain
is dependent on the combined inertia of the motor and load, and the selected bandwidth can be calculated
using the following formula:

Motor Power [kW]
is the motor power in [kW] (i.e. enter ‘4’ kW instead of ‘4000’ W in the formula). A practical value for the Bandwith is 20 rad/s.
Check the result of the Par. PI-02

calculation against the following formula (not required if you are using a high resolution feedback
such as a SinCos feedback):
