Number of position feedback pulses per motor revolution
n (Value after multiplication of F⋅FG)
Reduce the following fraction: =
d 1,000,000
n
Is A = 8,000,000 × an integer?
d
Obtain the smallest m so that the result of m
A is an integer.
Follow the setting procedure shown below.
This setting reduces the detection unit by a factor of m.
<1> Reduce the following:
Conversion coefficient (numerator) n
= × m
Conversion coefficient (denominator) d
<2> Multiply CMR by m.
<3> Reduce the following:
F⋅FG (numerator) Current F⋅FG (numerator)
= × m
F⋅FG (denominator) Current F⋅FG (denominator)
<4> Multiply the reference counter capacity by m.
<5> Multiply the effective area by m.
<6> Multiply the positional deviation threshold during movement
by m.
<7> Multiply the positional deviation threshold in the stop state by
m.
<8> Multiply the backlash by m.
<9> Multiply the scale factor of the pitch error compensation by
Set the following
(conventional method):
Conversion coefficient (numerator) n
=
Conversion coefficient (denominator) d
No
Yes
