For parameters set in detection units, see the list in Appendix C.
Number of position feedback pulses per motor revolution
n (Value after multiplication of F⋅FG)
Reduce the following fraction: =
d 1,000,000
n
Calculate A = 31,250 × . Which range is value A in?
d
B = A × 16 B = A × 4 B = A
Is B an integer?
Obtain the smallest m so that the result of m × B 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 m.
Set the following
(conventional method):
Conversion coefficient (numerator) n
=
Conversion coefficient (denominator) d
A < 2000 2000 ≤ A < 8192
A ≥ 8192
