Operation
WARNING!
During both the Velocity and Position tuning procedures the PositionServo
drive will perform rotation (motion) of the motor shaft in the forward and
reverse directions at velocities based on the settings made by the user.
Ensure that the motor and associated mechanics of the system are safe to
operate in the way specified during these procedures.
6.6.1 Tuning the Drive in Velocity Mode
1) Parameter Setup
Set up the motor as per the instructions given in the relevant section of this manual. The
motor must be configured correctly prior to tuning taking place.
The parameters Drive Mode, Reference and Enable Switch Function are configured
automatically by the velocity tuning program. They are not required to be set at this
stage.
2) Importing the Velocity Tuning Program
Before importing the Velocity Tuning Program, the example programs must be installed
from the Documentation CD that shipped with the drive. If this has not been done then
please do so now.
To load the TuneV program file to the drive, select [Indexer Program] in the MotionView
Parameter Tree. Select [Import program from file] on the main toolbar. Navigate to
[C:\Program Files\AC Technology\MotionView6.xx\Help\940Examples]. If during the
installation of the Documentation CD files a different default directory was selected,
then navigate to that directory. Click on the [TuneV.txt] file and select [Open].
3) Editing the Velocity Tuning Program
The Tune Velocity Program creates a step velocity demand in the forward and reverse
directions that the drive will attempt to follow (based on its velocity gain settings). The
drive will run for a set time in the forward direction and then reverse the reference and
run for the same set time in the reverse direction, showing the acceleration, deceleration
and steady state performance.
The speed and period (time for one complete cycle - forward and reverse) is set in the
Indexer program with the following statements:
; Motion Parameters
Define SpeedReference 5
; speed reference in Rps
Define Period 500 ; time in millisec
Adjust these parameters to values suitable to the application in which the drive is used
before going to the next step.
