Basic Operation
Multiplies the input frequency (Hz) of INA by 60 and displays the result in rpm.
When the appropriate prescale value is selected, the rotational speed of the ob-
ject is displayed. Obtain display value D as follows:
x 60 x α
D = f
A
f : Input frequency of INA (Hz)
A
α: Prescale value
INB input will be ignored.

Where,
N: Number of pulses per rotation
πD: Length (m) of one rotation
Example:
Displaying rotations (rpm) on condition that there are two pulses per revolu-
tion.
Prescaling value (α) = 1/2 = 0.5 = 5.0000 x 10
Y
Prescale value = X x 10
X (mantissa) of input A = 5.0000
Y (exponent) of input A = –1
Refer to 4-2 Setting Mode.
Measures the rotations of the roll.
