Toshiba V200 user manual Single Phase Speed Counter

5.4 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.
