Enable SPD function
M1037, D1037
1. M1037 and D1037 can be used to enable 8 sets of SPD instructions. When M1037 is ON, 8
sets of SPD instructions will be enabled. When M1037 is OFF, the function will be disabled.
2. The detected speed will be stored in the registers designated by D1037, e.g. if D1037 = K100,
the user has to set up the value in D100, indicating the interval for capturing the speed value
(unit: ms). In addition, the captured speed value will be stored in D101 ~ D108 in order.
※ When the function is enabled, C235~C242 will be occupied and unavailable in PLC
execution process program.
