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-jjCDT-D or CPM2A-jjCDT1-D.
The following diagram shows the configuration for a CPM2A, but the configura-
tion for a CPM2C is identical.

10 to 500 Hz (accuracy 1 Hz)
20 Hz to 1 kHz (accuracy 1 Hz)
300 Hz to 20 kHz (accuracy 25 Hz) (See note 2.)

Note 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(––).
