Control conditions:
Specify the starting number of the rotor(CN0):
CNO=0: begins the number of the position of the rotor with 0.
CNO=1: begins the number of the position of the rotor with 1.
Select the rotation direction via the shorter path or not: (DIR):
DIR=0: no direction is selected. The direction of rotation is only forward.
DIR=1: selected. The direction of rotation is forward/backward.
Specify the operating conditions (POS):
POS=0: calculate the goal position.
POS=1: calculates the position one position before the goal position.
Specify the position or the number of steps(INC):
INC=0: calculates the number of the position. If the position one position before
the goal position is to be calculated, specify INC=0 and POS=1.
INC=1: calculates the number of steps. If the difference between the current
position and the goal position is to be calculated, specify INC=1 and
POS=0.
Execution instruction (ACT):
ACT= 0
：
the ROT instruction is not executed. W does not change.
ACT
＝
1
：
executed. Normally, set ACT=0. If the operation results are required,
set ACT=1.
Parameter:
S1
：
specify the rotor indexing number.
S2
：
specify the address storing the current position.
S3
：
specify the address storing the goal position(or instruction value), for example the
address storing the CNC output T code.
S4 ： calculate the number of steps for the rotor to rotate, the number of steps up to the
position one position before, or the position before the goal. When the calculating
result is to be used, always check that if ACT=1.
