Number of position pulses (PPLS)

−
When a Serial A or αA1000 built-in pulse coder is used, set the
following:
Number of feedback pulses from
separate detector/motor revolution
× PULCO
8,192
#7 #6 #5 #4 #3 #2 #1 #0
1804
−
PLC0
2000
−
PLC0 (#0) The number of velocity pulses and the number of position pulses are:
0: Used as is ← To be set
1: Used after multiplication by 10
Example of setting
When the Series 15-B and serial pulse coder A are
used, and a 0.01-µm separate position detector is
used with a machine having a travel of 4 mm per
motor revolution
No. 1804#0 = 0
No. 1732 = 100
No. 1876 = 8,192 ÷ 100 = 82
No. 1891 = (400,000 ÷ 8,192) × 82 = 4,004
NOTE
When PMC velocity control is used, and a very small
value is set as the number of velocity pulses
(PULCO), the difference between a specified velocity
and actual velocity may become large. In such a
case, set the number of velocity pulses as described
in (b) below.
