The variable space occupied by the preceding code is as follows:
Variable Function Operation
D200
Used as a counter
register
The three units are preset by the user program.D201
Called window number
setting
D202
Called workpiece
number setting
M0 A-phase signal
The following code is executed before the user
program scans this statement:
X1
X0
（M0）
（M1）
X2
（M2）
M1 B-phase signal
M2
Zero-point detection
signal
M3
High-speed rotation in
the forward direction
The results of M3 to M7 are automatically
acquired when X10 = ON.
M3 to M7 are OFF when X10 = OFF.
M4
Low-speed rotation in
the forward direction
M5 Stop
M6
Low-speed rotation in
the reverse direction
M7
High-speed rotation in
the reverse direction
M3 to M7 are output by Y ports in the following user program. Only externally executed elements need to
be controlled.
D200 is cleared when the ow is active and the zero-point signal M2 = ON. Operation starts only after the
clearing operation is completed.
The ROTC instruction can be executed only once in a program.
