Operation
6.7.2 Manually Tuning the Drive in Velocity Mode
The PositionServo drive may also be tuned manually. Follow the procedure in this paragraph to tune 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] on main toolbar. Navigate to [C:\Lenze-ACTech\MVOB\Programming_Examples]. 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.
4) Compile and Download Indexer Program to Drive
In the [Indexer program] folder in MotionView, select the [Load W Source] button on the program toolbar.
The TuneV program will be compiled and sent to the drive. Click [Run] on the program toolbar to run the
TuneV program. Do NOT enable the drive (via input A3) at this stage.
