description
You can select the numerator of the command scalar.
*1:Select the 1st. or 2nd. numerator with scalar input switching
(DIV: CN I/F Pin 28) .
*2:Use the 3rd and 4th command scalars only for special opera-
tions such as "fill-close" operations. For details, see Full-
Close Specifications.
<Example>
・Basic relation is defined so as the motor runs one revolution
with the command input of encoder resolution(f), when the scale
ratio is 1.
Therefore, when the encoder resolution is 10000 P/r, it is nec-
essary to enter f=5000 pulses in case of scale ratio of 2, and
f=40000 pulse in case of scale ratio of 1/4 to turn the motor
one revolution.
・ Set-up the Pr46, Pr4A and Pr4B so that the post-scaling inter
nal command (F) equals the resolution (10000 or 217) of the
encoder.
F = f x (Pr46 x 2
Pr4A
)/Pr4B = 10000 or 2

F: Internal command pulse counts required for motor one
revolution
f: Command pulse counts required for motor one revolution
