2.9.4. Programming Order
Function
1) Make sure the motor runs properly. Do the following:
Set the drive to control the motor based on drive
2
output frequency.
Set the motor parameters using nameplate data.
Run Automatic Motor Adaptation.
2) Check that the motor is running in the right direction.
Press the "Hand On" LCP key and the ^ key to
make the motor turn slowly. Check that the mo-
tor runs in the correct direction.
3) Make sure the frequency converter limits are set to safe values
Check that the ramp settings are within capabil-
ities of the drive and allowed application oper-
ating 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.
Set up Analog Input 54 as a feedback input.
Select the appropriate reference/feedback unit.
5) Configure the setpoint reference for the PID controller.
Set acceptable limits for the setpoint reference.
Set up Analog Input 53 as Reference 1 Source.
6) Scale the analog inputs used for setpoint reference and feedback.
Scale Analog Input 53 for the pressure range of
the potentiometer (0 - 10 Bar, 0 - 10 V).
Scale Analog Input 54 for pressure sensor (0 -
10 Bar, 4 - 20 mA)
7) Tune the PID controller parameters.
Adjust the drive's Closed Loop Controller, if nee-
ded.
8) Finished!
Save the parameter setting to the LCP for safe
keeping
