Parameter Screens
After selecting a group using one of the soft keys, the FM-3 will display a Parameter screen
for that group. This screen could be either the first screen in the group or the last screen you
used in that group. The FM-3 keeps track of the last Parameter screen viewed in each group
and returns to that screen when you come back to the group. This is reset on power-up and
the FM-3 displays the first Parameter screen in the group.
In this screen, the parameter name is shown on the first line of the display. The up/down arrow
keys are used to scroll through the parameters available in the selected group.The second line
displays the condition or value of parameters. The third line displays the soft key actions.
The left/right arrow keys are used to scroll through the parameters when the “<“ and “>”
symbols are shown.
Numeric parameter units are sometimes shown before the actual value, because the parameter
value and the units cannot be displayed on one line. The unit of measure will appear on the
second line for about one second. Then the actual parameter value will appear. The parameter
value is updated about five times a second.
How Motion Works
The FM-3 provides three types of motion: jogging, homes and indexing. Only one index, jog
or home may be in process at any given moment (exclusionary motion types). Through
assignments and programs, the FM-3 can sequentially run various motion routines. The
Positive direction parameter affects all motion types by specifying which direction of motor
revolution (CW or CCW) is considered motion in the “+” direction.
How Jogging Works
Jogging produces rotation of the motor at controlled velocities in a positive or negative
direction.
Assignments to jogs are level sensitive such that when the jog input is turned on, jogging
begins and continues jogging until the jog input is removed.
