Section 6-3
Note
The bit image is shown below:
• When the master axis is in reverse rotation, the CAM data is read tracing
the data numbers in the reverse order.
• When Link option is one of 8 to 13 (Only for one cycle from the starting to
ending data number), the synchronization will be completed once the
master axis travels for Link distance in + or
−
direction from the synchroni-
zation start position.
• But if the master axis reciprocates within the ranges of +Link distance] or
-{Link distance}, the slave axis continues to move.
• The position of the master axis at link start can be specified with Link start
position.
• Master axis classification determines whether to synchronize the slave
axis with the master axis command value or feedback value.
• Command execution completion varies depending on the link option.
• During the command execution, the command code “0016h” is output to
the system variable “Command execution status” (SW0228 for Axis 1).
(For details of command codes, see
Code in Command Execution Status
Phase and Displacement
of CAM Data
Restriction on phase:
• To use the CAM data for "CAM (Electronic cam, single axis)" and "CAM-
BOX (Electronic cam, synchronous)" commands, the phase data should
be arranged in an ascending order (i.e. the greater the data number is,
the larger the phase will be).
• When specifying the starting and ending points, the restriction varies
depending on the used data as shown below.

Data
Restriction
CAM data
Even with the starting and ending points specified, the
other data will not be ignored. Therefore, the conditions
mentioned above have to be met even for the unused
area.
Position data/Global
general variable
The data other than the starting and ending points speci-
fied will be ignored. Therefore, the conditions mentioned
above do not have to be met for the unused area.
