5.2.7. The Axis Menu
The Axis menu allows one of the axes to be selected for display. The axes are listed by
number in the same order they are listed on the position display or axes configuration
page. To display multiple axes simultaneously, use the AerPlot utility.
5.2.8. The Tools Menu
The Tools menu allows the Status, Control, and Cursor toolbars to be displayed across the
top of the plot, below the menu. Sec_Num_FFTAnalysis
The FFT Analysis menu selection - see Section 5.3.2.
The Hard Reset menu selection allows the controller to be reset to its power-up state. This
selection should not be used.
The Fault Acknowledge selection will attempt to acknowledge and clear any faults that
are present. The Fault Ack button, on the status tool bar, will also attempt to clear the
faults.
The Auto Tune menu selection – see Section 5.4.
5.3. Using AerTune
Within AerTune there are various controls for exercising the axis. These include Step+
and Step– buttons, for moving the axis the incremental distance specified by the Step
Move parameters. There is also an Auto button for initiating an auto cycle of the axis,
which will cycle the axis back and forth by the amount in the distance entry field. The
initial direction is determined by the button selected, either plus or minus. The axis may
be stopped during a move by selecting the Halt button. A button is also provided for
enabling/disabling the axis. The Clear button will clear any faults and their associated
messages that may occur while exercising the axis.
The Step Move parameters allow the user to define a move profile typical to the desired
application. The Distance and Speed are specified in machine steps and machine steps per
second. All other Move parameters are the respective axis parameters for the axis. For
additional information on the axis parameters, refer to Appendix C: Parameters.
The ACCELMODE/DECELMODE parameters define the acceleration and deceleration as
Linear/1-Cosine) and Time/Rate based, as follows:
0 – (1-Cosine) – Time Based
1 – Linear Ramping – Time Based
2 – (1-Cosine) Ramping – Rate Based (Recommended)
3 – Linear Ramping – Rate Based
The ACCEL/DECEL entry fields specify the Acceleration/Deceleration time in
milliseconds when Time based ramping is active. The units are milliseconds (i.e., a one
second ramp would be specified as 1000 [milliseconds]). The
ACCELRATE/DECELRATE entry fields specify the Acceleration/Deceleration rate in
machine counts per second
2
when Rate based ramping is active.
The Gain parameter fields (all Axis parameters) allow the user to adjust the response of
the servo loop. The PGain parameter varies the position loop gain of the servo loop and
minimizes position errors during acceleration and deceleration while at rest. The Kp
