2.7 High Speed Counter [C]
1
General-purpose inputs X000 to X007 (X003) are used for high speed counter inputs. An encoder*1 adopting
the output type shown in the table below can be connected depending on the connected terminal.
Encoders adopting the voltage output type and absolute encoders cannot be connected to high speed
counter inputs.
→ For the wiring, refer to the manual (Hardware Edition) of the PLC main unit.
