[Setting reference counter capacity]
1896 (FS15i)
Reference counter capacity
1821 (FS30i,16i)
Set a value listed in the following table according to the detector used.
Detector Reference counter capacity
αiCZ 512S
Set the number of pulses per motor revolution (detection
unit) or the fraction that the number is devided by an
integer value.
αiCZ 768S
Set the number of pulses per motor 1/3 revolution
(detection unit) or the fraction that the number is devided
by an integer value.
αiCZ 1024S
Set the number of pulses per motor revolution (detection
unit) or the fraction that the number is devided by an
integer value.
(Example of parameter setting)
[System configuration]
• The Series 30i is used.
• An 88-pole/rev, synchronous built-in servo motor is used.
• The detector is the αiCZ 512S.
• The least input increment of the controller is 1/1000 deg.
• Gear ratio 1:1
[Parameter setting]
AMR=01011000 (88 in decimal representation)
Flexible feed gear (N/M) = 360,000/500,000 = 18/25, so parameter No. 2084 =
18, and parameter No. 2085 = 25
Number of velocity pulses = 4096
Number of position pulses = 6250
Reference counter capacity = 360,000
