FC 300 Design Guide
Introduction to FC 300
1. Start/Stop via switch connected to terminal 18.
2. Temperature reference via potentiometer ( 23 - 95°F (-5 - 35°C), 0-10 VDC) connected to te rm inal 53.
3. Temperature feed back via transmitter (14 -104°F (-10-40°C), 4-20 mA) connected to
terminal 54. Switch S202 set to ON (current input).
Function Par. no. Setting
1) Make sure the motor runs prop erly. Do the following:
Set the motor parameters using n am eplate
data
1-2* As specified by motor name plate
Have the adjustable frequency drive make an
Automatic Motor Adaptation
1-29 [1] Enable complete AMA
2) Check that the motor is running in the right direction.
Press the "Hand On" LCP key. Check that the
motor is running and note in which direction
it is turning.
Set a positive reference.
If the motor was turning in the wrong direction,
remove the motor plug and switch two of the
motor phases.
3) M ake sure the adjustable frequency drive limits are set to safe values
Check that the ramp settings are within
capabilities of the adjustable frequency
drive and allowed application operating
specifications.

5) Scale the analog inputs used for reference and feedback
Scale the Analog Input 1 (terminal 53) that
is used for the te mperature reference via
potentiometer (23 - 95°F/ -5 - 35°C, 0-10
VDC).
