You can reset the counter value for each counter.
There are the following three reset methods:
• Reset for internal reset
• Reset for external input
• Reset for phase-Z input
Change the Internal Reset Execution bit in the Encoder Counter Operation Command parameter from 0
to 1 to reset the counter to 0.
Encoder Counter Operation Command
on page 6-40 for information on the Internal Reset Exe-
cution bit.
If you set the External Input Logic Selection parameter for the external input to specify an N.O. contact,
the counter will reset to 0 on the rising edge of the external input.
If you set the External Input Logic Selection parameter for the external input to specify an N.C. contact,
the counter will reset to 0 on the falling edge of the external input.
To enable resetting, set the External Reset Enable bit of the Encoder Counter Operation Command
parameter to 1.
Encoder Counter Operation Command
on page 6-40 for information on the External Reset
Enable bit.
Precautions for Correct Use
If you reset a counter with an external input or the phase-Z input, a delay of up to 250
μ
s will
occur between the input and reset processing. The reset completed flag will turn ON the first
time input data is refreshed after processing is completed.
Additional Information
The NX-EC0212 and NX-EC0222 do not have any external inputs.
