3.2 Performance Specifications
3.2.1 Number of parameters that can be set
*1 The value can be configured in intelligent function module switch setting.
*2 The counting speed is affected by the pulse rise/fall time.
The number of pulses that can be counted depending on the counting speed is as follows. Note that the count may be
incorrect when pulses with long rise/fall time are counted.
3.2.1 Number of parameters that can be set
Configure the parameters of the initial setting and the auto refresh of the high-speed counter module within the number
of parameters that can be set to the CPU module or head module, including the number of parameters set for other
intelligent function modules. For the number of parameters that can be set to the CPU module and head module, refer
to the following.
MELSEC-L CPU Module User's Manual (Hardware Design, Maintenance and Inspection)
MELSEC-L CC-Link IE Field Network Head Module User's Manual
