*4. The command position captured by the CK3W-GC Unit becomes the SL2-100 transmission data at the
falling edge (rising edge) of the next interpolation clock.

Precautions for Correct Use
When you set synchronous mode for linear interpolation of a command position, set a multiple
of 10 µs to the phase or servo cycle set for an interpolation clock.
If it is not set correctly, the Galvo Scanner may not operate as intended.
 Operation in Asynchronous Mode
You can set any value to the interpolation clock (Phase or Servo) period.
The CK3W-GC Unit captures a command position at the falling edge (rising edge) of an interpola-
tion clock, and sends that command position in an SL2-100 transmission cycle at the falling edge
(rising edge) of the next interpolation clock.
As the SL2-100 data between interpolation clocks, the value calculated by linear interpolation is
sent.
In asynchronous mode, the interpolation may not be linear interpolation in calculation. If you always
need to use linear interpolation, use synchronous mode.
Although using this mode causes an error between the command position from the CPU Unit and
the shape of SL2-100 data, you can set any value to the phase or the servo cycle.
