(2) Electronic gear related parameters
The setting range of the following parameters, which configure the electronic gears, may be limited
according to the combination.

SV001 PC1*
Motor side gear
ratio
1 to 32767
SV002 PC2*
Machine side gear
ratio
Set the motor side and machine side gear ratio.
For the rotary axis, set the total deceleration (acceleration) ratio.
Even if the gear ratio is within the setting range, the electronic gears may
overflow and causes initial parameter error (servo alarm No. 37).
1 to 32767
SV018 PIT* Ball screw pitch Set the ball screw pitch. Set to "360" for the rotary axis.
1 to 32767
(mm/rev)
In the case of the semi-closed loop control
Set the same value as SV020 (RNG2).
(Refer to the explanation of SV020.)
1 to 9999
(kp/rev)
In the case of the full-closed loop control
This is available for the relative position oblong wave output specification
linear scale.
Set the number of pulses per ball screw pitch.
