Program Example
(1) The following program turns Y0 and Y1 ON and OFF once each second (flicker) when X20 is ON.
(Uses 100 ms timer)
[Ladder Mode] [List Mode]
[Timing Chart]
: + 0: Measures the number of table rotations (for system use) (BIN 16 bits)
+ 1: Call station number (BIN 16 bits)
+ 2: Call item number (BIN 16 bits)
n1 : Number of divisions of table (2 to 32767) (BIN 16 bits)
n2 : Number of low-speed sections (value from 0 to less than n1) (BIN 16 bits)
: + 0: A phase input signal (bits)
+ 1: B phase input signal (bits)
+ 2: 0 point detection input signal (bits)
+ 3: High speed forward rotation output signal (for system use) (bits)
+ 4: Low speed forward rotation output signal (for system use) (bits)
+ 5: Stop output signal (for system use) (bits)
+ 6: Low speed reverse rotation output signal (for system use) (bits)
+ 7: High speed reverse rotation output signal (for system use) (bits)
