Start Frequency Control
This function specifies the bits for pulse outputs (01000, 01001) and the fre-
quency scaling factor (1% to 1,000%), and starts the pulse output.
Pulse input port designation (000: High-speed counter)
Pulse output port designation (000: Pulse output 0; 010: Pulse output 1)
Frequency scaling factor setting
Frequency scaling factor
Register the frequency scaling factor to be set.

Note
When using SYNC(––) to specify a frequency scaling factor, be careful to keep
the pulse output frequency below 10 kHz.
Change Frequency Scaling Factor
This function changes the frequency scaling factor during synchronized control
(during pulse output) by specifying the bits for pulse outputs (01000, 01001) and
the frequency scaling factor (1% to 1,000%) and executing SYNC(––).
Stop Synchronized Control
This function stops the pulse outputs.

Note
The pulse output can also be stopped by switching the PC to PROGRAM mode.
Read Input Frequency
This function reads the input frequency PV.
