Synchronized Pulse Control (CPM2A/CPM2C Only)
By combining the CPM2A/CPM2C’s high-speed counter function with the pulse
output function, the output pulse frequency can be controlled as a specified mul-
tiple of the input pulse frequency.
Note
A CPU Unit with transistor outputs is required in order to use synchronized pulse
control, i.e., either a CPM2A-
CDT-D or CPM2A-
CDT1-D.
The following diagram shows the configuration for a CPM2A, but the configura-
tion for a CPM2C is identical.

1. Can be used as an ordinary input.
2. When 10 kHz or less, then the accuracy is
±
10 Hz.
3. Either can be selected as the output number, using SYNC(––).
