(Note 1) Position FB, position command, and droop are output as an interpolation unit.
EX) When "#1003 iunit" is B (1μµm) and output result is 2000:
20000 * 0.5 (interpolation unit) = 1000μm = 1mm
(Note 2) Output unit for the number of motor rotations is 0.01 r/min.
(Note 3) The same value as the load current displayed in the servo monitor screen is sampled for the load
current value of the servo and PLC axes. Output unit is %.
(Note 4) The same value as the load displayed in the spindle monitor screen is sampled for the load current
value of the spindle. Output unit is %.
Droop's sampling result is twice the value of a droop displayed in the servo/spindle monitor screen
of CNC monitor.

Setting examples for each purpose are shown below.
• For synchronized tapping: 3rd servo axis feedback (000300) - 1st spindle feedback (010000)
• For high-accuracy (roundness): 1st servo axis feedback (000100) - 2nd servo axis feedback (000200)
• For spindle synchronization: 1st spindle feedback (010000) - 2nd spindle feedback (020000)
