4.11.12 KCM CPU frequency input - J9
Fig. 4.18 CPU frequency input circuit
This circuit shows the frequency input that is available at the CPU pcb
at terminal J9.
The input function is programmed via the I-O menu, Setpoint Input
sub-menu as parameter <SOURCE> = <CPU =0-10kHz>. See the
specific application programming manual for exact programming.
• Logic level = 5-12 Vdc for a “true”
• For 24Vdc Power supply use an additional 2.2kOhm resistor in
series.
• Frequency range = 0-20 kHz
• Minimum pulse width = 15 sec
– Freq input (+) = J9-1
– Freq input (-) = J9-2
