Tuning Velocity Controller (Ziegler&Nichols)
AX5000 Tuning - Guide 9
Version: 1.0
Now reactivate the configuration.
Right-click on an axis in the oscilloscope and open the target
browser.
Select:
• the controller,
• the ADS port,
• the drive and the channel.
Use “drag and drop” to assign the signals to the oscilloscope
axes, as shown (picture below).
The signal scaling is not important for determining the stability
limit. To establish the relationship with the drive axis it may be
useful to enter the scaling factors in the property window of
the axis. The values can be taken from the "Scaling and NC
Parameters" window in the TC DriveManager.
If you start the recording now, the oscilloscope should not
issue an error message.
Nature and source of the danger!
If a German keyboard is used, the decimal symbol must be comma!
3.5 Starting the test movement
From "NC Functions" select the function "Velo Step
Sequence". To make the axis reverse, you have to
specify two velocities with different sign. Enter 1
second as "Idle time", for example, and a number of
cycles.
Attention
Nature and source of the danger
Since the position controller and the integral component of the velocity controller are not
active, the axis may drift into another positioning range during reversing.
