Programming Order - Danfoss VLT HVAC Drive FC 102 Design Manual

Introduction

2.8.10 Programming Order

NOTICE
This example assumes an induction motor is used, so 1-10 Motor Construction = [0] Asynchron.
Function
1) Make sure the motor runs properly. Do the following:
Set the motor parameters using nameplate data.
Run Automatic Motor Adaptation (AMA).
2) Check that the motor is running in the right direction.
Run motor rotation check.
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.
Switch from open loop to closed loop.
4) Configure the feedback to the PID controller.
Select the appropriate reference/feedback unit.
5) Configure the set-point reference for the PID controller.
Set acceptable limits for the set-point reference.
Choose current or voltage by switches S201 / S202
6) Scale the analogue inputs used for set-point reference and feedback.
Scale analogue Input 53 for the pressure range of the
potentiometer (0–10 Bar, 0–10 V).
Scale analogue input 54 for pressure sensor (0–10 Bar,
4–20 mA)
7) Tune the PID controller parameters.
Adjust the closed loop controller, if needed.
8) Finished
Save the parameter setting to the LCP

Setting
As specified by motor name plate
[1] Enable complete AMAand then run the AMA
function.
If the motor runs in the wrong direction, remove
power temporarily and reverse two of the motor
phases.
