First, calculate the parameters for the flexible feed gear.
[Flexible feed gear] Parameter Nos. 2084 and 2085
[Flexible feed gear N/M] = (Amount of table movement (degrees)
per detector revolution)/(detection unit
(degrees))/1,000,000
= 360 degrees/0.001 degree/1,000,000
= 36/100
Calculate the number of position pulses.
[Number of position pulses] Parameter No. 2024
Number of position pulses = 12500 × motor-to-table deceleration
ratio
= 12500 × (1/2) = 6250
This completes parameter setting.
Setting the signal direction of the separate detector
With a conventional parallel type separate detector, when the signal
direction of the separate detector and the movement direction of the
machine is opposite to each other, the feedback cable signal had to be
connected in reverse by hardware.
With a serial type separate detector, it is impossible to connect signal in
reverse. So, the signal direction can be reversed by setting the
parameter shown below.

RVRSE (#0) The signal direction of the separate detector is:
1: Reversed.
0: Not reversed.
NOTE
This parameter can be used only for serial type
separate detectors; the parameter cannot be used for
parallel type separate detectors. To reverse the
signal direction of a parallel type separate detector,
replace A and
