Filtering
function
Digital filter
X0~X7 have digital filtering function. Filtering time: 0,
8, 16, 32 or 64ms (selected through user programme)
Hardware
filter
Input terminals other than X0 ~ X7 are of hardware
filtering. Filtering time: about 10ms
High-speed function
X0~X7: high-speed counting, interrupt, and pulse
catching
X0 and X1: up to 50kHz counting frequency
X2~X5: up to 10kHz counting frequency
The sum of input frequency should be less than 60kHz
Common terminal
Only one common terminal: COM
The input terminal act as a counter has a limit over the maximum
frequency. Any frequency higher than that may result in incorrect
counting or abnormal system operation. Make sure that the input
terminal arrangement is reasonable and external sensors used are
proper.
Input connection example
The following diagram shows an example of IVC1L-1614MAR in
connection with an IVC1-0808ENR, which realizes simple positioning
control. The positioning signals from the PG are input through high
speed counting terminals X0 and X1, the limit switch signals that
require high-speed response can be input through high-speed
terminals X2 ~ X7. Other user signals can be input through any other
input terminals.

Output connection example
The following diagram shows an example of IVC1L-1614MAR in
connection with an IVC1-0808ENR. Different output groups can be
connected to different signal circuits with different voltages. Some (like
Y0-COM0) are connected to the 24Vdc circuit powered by local
24V-COM, some (like Y2-COM1) are connected to the 5Vdc low
voltage signal circuit, and others (like Y4~Y7) are connected to the
220Vac voltage signal circuit.
