Note: The input time constant can be set to 1, 2, 3, 5, 10, 20, 40, or 80 ms in the PLC setup.

High speed counter inputs

The following unit input bits can be used as high-speed counter inputs. The maximum count frequency is 5 kHz in differential phase mode and
20 kHz in the other modes.
Input Function
Differential phase mode
IN00000 A-phase pulse input
IN00001 B-phase pulse input
IN00002 Z-phase pulse input or hardware reset input
(IN00002 can be used as a normal input when it is not used as a high-speed counter input.)
The minimum pulse widths for inputs IN00000 (A-phase input) and IN00001 (B-phase input) are as follows:
Pulse plus direction input mode,
Up/down input mode, increment mode

Interrupt inputs

The 3G3MV-P10CDT is equipped with inputs that can be used as inter-
rupt inputs (interrupt input mode or counter mode) and quick-response
inputs. The minimum pulse width for these inputs is 50 µs.
Inputs IN00003 and IN00004 can be used as interrupt inputs.
