5.2.2 Single Phase speed - counter
This function counts the number of changes of the count input from OFF to ON during the every specified sampling
time. The count value in a sampling time is stored in the hold value register. This counter operation is enabled while
the soft-gate is ON. When the soft-gate is OFF, the hold value is cleared to 0. The setting range of the sampling time
is 1 to 1000 ms (1 ms units). The count value range is H0000 0000 to HFFFF FFFF (32-bit).
The function selection is done through configuration register1.
Function Register/device Remarks
Channel 1 Channel 2
Count input IP 1 (X000) IP 2 (X001)
Sampling time MW12 MW14 Data range: 1 to 1000
Hold value MW16 MW18 Data range: H0000 0000 to HFFFF FFFF
Soft-gate M320 M328 Operation is enabled when ON
Note 1) The setting data range of the sampling time is 1 to 1000. (1 ms multiplier)
Note 2) When both the channels are configured in high speed mode, IP1 & IP2 cannot be used as normal input
devices. However, if either one channel is configured in high speed mode, the input of other channel can be used as
normal input device.
Hardware condition:
Count input (X000 and X001)
ON/OFF pulse width: 10 micro or more (max. 50 kHz)
Interrupt assignment:
