Execute Self-tuning

NOTE: CML self-tuning takes approximately 3-4 seconds to complete. Speed Loop self-tuning
takes approximately 1 minute to complete. If Self Tuning is not initiated by the Quick Start
procedure, Self Tuning must be initiated via one the following menu level paths from the main
menu:

Speed/Voltage Loop (SPD)

Current Minor Loop (CML)

- Speed/Voltage Loop (SPD) Tuning

- CML Tuning

- - Self tuning Setup*

- Self tuning Setup*

- Self tuning

- Self tuning

NOTE: The following screen will not appear if FEEDBACK SELECT is set to ARMATURE VOLT.

PROGRAM

KEYPAD MANUAL FORWARD

CML and SPEED Loop - The system will perform tuning on the CML and then after completion,
perform tuning on the SPEED Loop.

CML only - The system will perform tuning on the CML only. NOTE: If the FEEDBACK SELECT
is set to ARMATURE VOLT, self-tuning assumes "CML only".

SPEED only - The system will perform tuning on the speed loop only.
NOTE: If tuning the speed loop separately, the CML should have been previously tuned for best
results. NOTE: Most applications use 150% for the MAXIMUM CURRENT to achieve the most
accurate results from self-tuning. The greater the difference between MAXIMUM CURRENT
and 150% yields a corresponding greater error in the values self-tuning calculates.

To execute self-tuning, perform the following steps:

1. Select the type of self-tuning to perform and then press ENTER.

The following screen appears:

Self Tuning

Press RUN to begin self-tuning.
Press CANCEL to abort.

Pressing CANCEL returns the display to the previous screen.

2. Press RUN.

NOTE: It is possible to display one of the monitor screens while self-tuning is active.
This allows the user to monitor the speed of the motor while self-tuning.

"Self-tuning is active." blinks on the display during self-tuning. The display updates as
indicated with the status of the loop being self tuned after it is complete. Once self-tuning is
complete and the gains are updated, the display updates with "Self Tuning has updated the
gains" and removes "Self Tuning is active."
