F5: Measuring Length
Measuring workpiece length
•
Basic operation
Displays the number of input A pulses while input B is ON.
The measurement value can be obtained using the following
formula:
D
=
C
×
α
C
: Number of pulses of input A while input B is ON
α
: Prescale value A
D
: Measured length
*TR: Recovery Time
The time required from the end of one measurement until completing
preparations for the next measurement. Allow at least 1 ms.
Referring to the following table, specify the prescale value
corresponding to the desired display unit
.
Na: Number of input A pulses per rotation
