Pulse Train Frequency Input
Pulse train input can be used for the frequency reference, operation target used for frequency refer-
ence and PID feedback value in PID control.
• To use pulse train input for the frequency reference, set Frequency Reference Selection (F01/C30)
to “12: Pulse train input.”
•
To use pulse train input for the operation target, set Frequency Reference Selection (F01/C30) to
“13: Calculation result” and set Frequency Calculation Operation Target 1/2 (E131/E132) to “7:
Pulse train frequency.”
• To use pulse train input for PID feedback, set PID Control Feedback Selection (E119) to “3: Pulse
train frequency.”
• Pulse train input uses input terminals [PIA], [PIB] and [PIZ].
