Configuring the Kinetix 3 Drive Chapter 5
The Oscilloscope window has these parameters and commands associated with it.
Parameter Description
Channel A and B
Input Signal Click the down arrow to the right of the Channel Setup dialog to
select a Channel (A or B).
Note: The resolution of this signal may be confusing if Velocity
Feedback is selected. See the topic Velocity Motor Feedback
Resolution for information on how resolution is derived for
various motor and feedback combinations.
Scale Type Scale Types are:
• Auto
• Manual
• Same As ChA (available for Channel B only)
Scale The amplitude of the selected channel input signal that can be
displayed between gridlines of the oscilloscope, in the units of
the drive signal. It is dependent on the signal selected. If the
Scale is left at its default value of 0, The data is auto scaled to
fit the graph.
Note: Visible only if Scale Type is Manual.
Offset The trace offset for the selected Channel Input. Its range
depends on the signal selected. A value of zero places the zero
value of the signal at the middle grid line. A nonzero offset
shifts the trace up or down so that the offset value is positioned
at the middle grid line.
Note: Visible only if Scale Type is Manual.
I/O Monitoring Type The signal that want to be displayed between I/O signals
Note: Visible only if Input Signal is Digital IO.
Sweep Parameters
Sample Period The time, in milliseconds, between samples that constitute a
trace. The horizontal resolution of the oscilloscope is 128
samples. (For example, selecting a sample period of 1.0 ms will
result in 128 ms of data being displayed.)
Note: The Sample Period range is 0.2…20 ms with a resolution
of 0.2 ms.
Samples per Division Number of samples per division. For example, 32 samples per
division will result in 4 horizontal divisions.
Trigger Source The drive signal that will set off the trigger and begin tracing the
selected channel signal, upon the occurrence of the Trigger
Mode at the Trigger Threshold. Click the down arrow to the right
of the Channel Setup dialog box to set the channel.
Trigger Mode The event that triggers oscilloscope tracing:
• Immediate: begins tracing immediately after the trigger is
armed.
• Rising Edge: begins tracing when the selected Trigger Source
value increases above the Trigger Threshold value.
• Falling Edge: begins tracing when the selected Trigger Source
value decreases below the Trigger Threshold value.
Trigger Threshold The value of the Trigger Source drive signal that begins tracing.
Trigger Threshold selections are:
• Rising Edge
• Falling Edge
Trigger Status The current status of the oscilloscope trigger:
• Idle
• Awaiting Trigger
• Collecting Data
