Prescaling
To display rotational speeds, circumferential speeds, or other
values based on input pulse calculations, the rotational speed
must be multiplied by a factor input before the input pulses are
measured. This factor is called
a prescale value.
K3NR
Proximity Sensor
Rotation speed (rpm) = f × 60 × a
Where,
f: Input pulse frequency (p/s)
a: Prescale value
If there are 5 pulses per rotation, then an accurate rotation
speed can be calculated if a = 1/5 (= 0.2 = 2 × 10-1).
In actual application, input as follows:
Mantissa X = 2.0000
Exponent Y = 10-1
Auto-zero Time (Set before use.)
In operation modes 1 to 6, the time to force-zero the frequency if
no pulse is received for a specified period can be set. This time
is called the auto-zero time. Set the auto-zero time to a value
that is somewhat longer than the longest input pulse interval. (If
the time setting is too long or if the factory-set value is used, the
display may not return to zero even if no input pulse is
received.)
