276 Data Logging for Mx2000 revision 4.0
11.1 - Data Logging
The controller has the capability to perform data
logging of eight items when the selected trigger
occurs. Each logged item has 200 points. The Data
Logging is accessible from the
Utility
menu.
An MX2000 project in the PC needs to be open to
perform data logging. Data logging can be triggered
by either Host or program execution commanded
motion.
11.1.1 - Parameter & Trigger Setup
The parameter & trigger setup is accessed by
clicking on the
Utility
menu,
Logging
item and then
Parameter & Trigger Setup
item. A maximum of
eight parameters, independent of the number of axes,
may be selected for data logging. To select or
deselect a data logging item click on the desired axis
of the parameter check box.
The parameter selection list is: Position error,
Absolute position, Encoder position, Integration
error, Analog command, Accel feed forward, Analog
input 1, Analog input 2, Encoder velocity, Event 1
state, Event 2 state, +Limit state, –Limit state and
Command Velocity.
Trigger Axis
selects the axis that will trigger the
logging. The trigger occurs when the selected axis
motion starts.
Display Time
select the logging period for data
logging in seconds.
Trigger Delay
selects the delay, in millisecs, after
the trigger occurs and data logging begins.
Cancel
exits the logging Parameter & Trigger setup
without saving the values.
Ok
sends the parameter listing, trigger axis, display
time, Trigger delay to the controller and arms the
motion trigger for data logging. The terminal mode
window opens at this time allowing motion to be
commanded.
11.1.1.1 Parameter List Descriptions
Position error
is the position difference between the
commanded position and the encoder position. This
waveform is in units.
Absolute position
is the commanded position of an
axis. This waveform is in units.
Encoder position
is the encoder position of an axis.
This is the actual position of a closed loop stepper or
servo axis. This waveform is in units.
Integration error
is the integration error
contribution to the analog output voltage for a servo
drive. This waveform is in volts.
Analog command (torque)
is the commanded
torque voltage for a servo drive axis or the
commanded analog output voltage of an axis. This
waveform is in volts.
Analog input 1
is the IN+ input voltage referenced
to AGND if single ended mode is selected or the
differencial input voltage of an axis. This waveform
is in volts.
Analog input 2
is the IN- input voltage referenced
to AGND if single ended mode is selected. This
waveform is in volts.
Encoder velocity
is the measured velocity of the
encoder input. This waveform is in units/sec.
Event 1 state
is the state of the event 1 input of the
axis.
Event 2 state
is the state of the event 2 input of the
axis.
+Limit state
is the state of the +limit input of the
axis.
-Limit state
is the state of the -limit input of the
axis.
