1) Make sure the motor runs properly. Do the follo wing:
Set the motor parameters using nam eplate
data
1-2* As specified by motor nameplate
Have the adjustable frequency d rive do an
automatic motor adaptation.
1-29 [1] Enable complete AMA
2) Check that the motor is r u nning 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.

4) Configure the reference to the process control.
Allow for an “asymmetrical” reference range by
selecting the “Min - Max” refe r ence range.

Set up Analog Input 53 as a reference re source 3-15 Not necessary (default)
5) Scale the analog inputs used for reference and feedback.
Scale the Analog Input 1 (terminal 53) that
is used for t he temperature re f erence via
potentiometer (23° - 95°F [-5° - 35°C], 0-10
VDC).

6) Configure th e feedback to the process control.
Set up Analog Input 54 as a feedback resource 7-20 [2] Analog input 54
7) Tune the process control PID parameters.
Select inverse control. 7-30 [1] Inverse
Use the tuning guidelines when relevant or
tune ma nually.
