Normal traverse operation
in Pass Mode (for reference)
The acceleration/deceleration
time is maintained for each
block and the speed is
decreased.
None
Note Passing, however, will
not be performed if the
time is the same or
below the minimum
pass time.
• The linked traverse function is enabled from when the program is exe-
cuted from the start after the customized functions have been enabled.
• When the rotational speed [p/s] is lower than the traverse axis speed [p/
s]), unevenness can occur in the speed of the traverse axis. Adjust the
pulse rate if unevenness occurs.
Position data addresses A1970 to A1985 can be allocated to user-specified
addresses in I/O memory in the CIO, DM, or EM Areas. This reduces the work
required to write ladder programs because this position data is automatically
transferred between the CPU Unit and MC Unit without any special program-
ming.
The data is exchanged at the same time as the CIO Area words allocated to
the MC Unit. Data can also be changed (from MC Unit position data to CPU
Unit only) when positioning with travel distances set with the stopover func-
tion.

Linked traverse (customized function)
Triangular control is performed for the linked
G32 commands.
2 ms
Note If the time is less than 2 m, an error will
occur (added axis speed exceeded) and
the rotating axis will decelerate to a stop.
The traverse axis will stop after the accu-
mulated pulses have been consumed.
When this error occurs, continuous opera-
tion cannot be continued (a traverse con-
tinuation error will occur).
