Motion Perfect Tools
Section 7-5
Jog Buttons
The screen provides Forward and Reverse Jog Buttons for each axis. When
the button is pushed the jogging is activated and the corresponding virtual
input will be OFF. Prior to the activation the value of the Jog Speed field will
be written to the JOGSPEED parameter. When released this input is ON and
the jogging will be stopped.
Warnings Area
The Warnings Area shows the status of the last jog request.
When a Jog Button is pressed, a warning will be given for any of the following:
• The axis is a SERVO axis and the servo is OFF
• The jog speed is 0.
• The acceleration or deceleration rate for this axis is 0
• The forward or reverse jog input is out of range
• There is already a move other than a jog being performed on this axis

Oscilloscope
The software oscilloscope can be used to trace axis and motion parameters,
which is a helpful tool for program development and system setup. The oscil-
loscope provides four channels, each capable of recording at up to 1,000
samples/s, with manual cycling or program-linked triggering.
The MC Unit records the data at the selected frequency, and then uploads the
information to the scope to be displayed. If a larger time base value is used,
the data is retrieved in sections, and the trace is seen to be plotted in sections
across the display.
Note
1.
Motion Perfect uses the SCOPE command when running the Oscilloscope
function.
2.
To minimize calculation time for writing the real-time data, the SCOPE
command is writing raw data to the Table array. For example
a)
The parameters are written in encoder edges (per second) and there-
fore not compensated for the UNITS conversion factor.
b)
The MSPEED parameter is written as the change in encoder edges
per servo period.
3.
Applications like the CAM command, CAMBOX command and the SCOPE
command all use the same Table as the data area.
Exactly when the MC Unit starts to record the required data depends upon
whether it is in Manual or Program Trigger Mode.
• In Program Trigger Mode, it starts recording data when it encounters a
TRIGGER command in a program running on the MC Unit.
• In Manual Mode, it starts recording data immediately.
The Trigger Button can be used to start the scope as soon as the required
settings have been made. The scope controls are divided into the two parts:
the general controls and the channel specific controls.
