PlsCnt
Variable name Range of values Default Unit Data size Attribute
Pulse count monitoring 0 to 32767 - 1
Unsigned
2-word data
Readable
- Explanation
This variable can be used to reference the pulse count when the pulse counter function is selected.
The data referenced with this variable corresponds to the data monitored by the pulse counter monitoring function (d028). This
variable is read-only.
This function doesn't correspond in the WJ200 Series.
- Sample program : This program turns on contact output when the pulse count exceeds 2000 (times).

2-word data
Readable
- Explanation
This variable can be used to reference current position information when the absolute position control function is selected.
The data referenced with this variable corresponds to the data monitored by the current position monitoring function (d030).
This variable is read-only.
When “03” (high-resolution absolute position control) has been selected for control pulse setting (P012), the parenthesized
range of values applies (Only SJ700).
This function doesn't correspond in the L700/SJ700B Series.
- Sample program : This program turns on contact output when the current position data exceeds 100,000 (pulses)
