• Corner angle w/o slowdown specifies the maximum corner angle to be driven without any speed limitations. 15000
mdegrees is same as 15 degrees.
• Automatic drift adjustment drift is periodically measured and compensated automatically.
• Acceleration S-Curve Enabled enables/disables S curve acceleration for smoother motion with high acceleration values.
• The Y2 adjust screen is for setting parameters related to synchronization of the first longitudinal drive (Y1-master)
with the second longitudinal drive (Y2-slave) Please try the Defaults first, most machines work well with them. Click
the Defaults button in the Y2 adjust screen.
• First step is a control value to be given when there is 1 increment difference in Y1 and Y2 positions. A control value of
1 equals maximum speed signal voltage divided by 16000.
• Static P-Gain gives corrections based only on the magnitude of difference between Y1 and Y2. The correction is linear.
• Static P2-Gain is like the P-gain but is not linear. It has it’s full value at the edge of the adjust window, but with the Y1/
Y2 difference being half of the adjust window, the effect of this parameter is only one quarter.
• Adjust window is given in m (=1mm/1000). The default value is 2000 meaning that the Y1-Y2 distance related values
will reach maximum if the Y1-Y2 difference is 2mm or greater.
• Dynamic P-Gain and Dynamic P2-Gain are related not only to the difference of Y1-Y2 but also to the speed. They will
have maximum effect at the edge of adjust window if the machine is driving with maximum speed. In low speeds these
values have almost no effect to the Y2 correction.
• Error limit will set the Y1-Y2 difference where the machine must be stopped. The default value is 5000 m (=5mm =
0.2”)
• Slowdown time is the time spent to stop the machine from full speed. Default is 50 msec = 0.05 seconds
First press Apply to temporarily store the parameters before running the test Rosette.
When running the test Rosette, it is necessary to watch actual machine motion, and therefore you should have your
drives engaged to the pinion rack.
Pressing the Test run button will allow you to run a test Rosette of desired size and speed. The test starts when you
click the Start button and press the MOVE AHEAD push button on the front panel of the control. When motion is ok click
Save and Close.
NOTE!
After completing this section, it is advisable to do a total restart and password-save the changes permanently when
prompted.
