FC 300 Design Guide
Function
1) Make sure the motor runs properly. Do the following:
Set the motor parameters using name
plate data
Have the frequency converter make
an Automatic Motor Adaptation
2) Check that the motor is running in the right direction.
Press the "Hand On" LCP key. Check
that the motor runs and note in which
direction it is turning.
If the motor was turning in the wrong
direction, remove the motor plug and
switch two of the motor phases.
3) Make sure the frequency converter limits are set to safe values
Check that the ramp settings are
within capabilities of the frequency
converter and allowed application
operating specifications.
Prohibit the motor from reversing if
necessary
Set acceptable limits for the motor
speed and frequency
4) Configure the reference to the Process Control
Allow for an "asymmetrical" reference
range by selecting the "Min - Max"
Reference Range
Select the appropriate reference unit
Set acceptable limits for the sum of
all references
Set up Analog Input 53 as a reference
resource
5) Scale the analog inputs used for reference and feedback
Scale the Analog Input 1 (terminal
53) that is used for the temperature
reference via potentiometer (-5-35°C,
0-10 VDC).
Scale the Analog Input 2 (terminal
54) that is used for the temperature
feedback via transmitter (-10-40°C,
4-20 mA)
6) Configure the feedback to the Process Control
Set up Analog Input 54 as a feedback
resource
7) Tune the Process Control PID parameters
Select inverse control.
Use the tuning guidelines when
relevant or tune manually
8) Finished!
Save the parameter setting to the
LCP for safe keeping
