3. Introduction to FC 300
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
1) Make sure the motor runs properly. Do the following:
Set the motor parameters using nameplate
data
Have the VLT make an Automatic Motor
Adaptation
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 di-
rection it is turning (henceforth referred to
as the "positive direction").
Go to par. 16-20. Turn the motor slowly in
the positive direction. It must be turned so
slowly (only a few RPM) that it can be de-
termined if the value in par. 16-20 is in-
creasing or decreasing.
If par. 16-20 is decreasing, then change the
encoder direction in par. 5-71.
3) Make sure the drive limits are set to safe values.
Set acceptable limits for the references.
Make sure that the ramp settings are within
drive capabilities and allowed application
operating specifications.
Set acceptable limits for the motor speed
and frequency.
4) Configure the speed control and select the motor control principle.
Activation of Speed Control
Selection of Motor Control Principle
5) Configure and scale the reference to the speed control.
Set up Analog Input 53 as a reference
source
Scale Analog Input 53 0 RPM (0 V) to 1500
RPM (10 V)
6) Configure the 24 V HTL encoder signal as feedback for motor control and the speed control.
Set up digital input 32 and 33 as encoder
inputs
Choose terminal 32/33 as motor feedback 1-02
Choose terminal 32/33 as Speed PID feed-
back
7) Tune the speed control PID parameters.
Use the tuning guidelines when relevant or
tune manually.
8) Finished!
Save the parameter settings to the LCP for
safekeeping.
