FC 300 Design Guide
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 explanation of set-
tings in the section "How to Program."
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. Check that the
motor is running and note in which direction
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 determined if the
value in par. 16-20 is increasing 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.
Check 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 resource
Scale Analog Input 53 0 RPM (0 V) to 1500
RPM (10V)
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
Choose terminal 32/33 as motor feedback
Choose terminal 32/33 as Speed PID feedback
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
