bits define sequentially 128 configurations by selecting one by one modules 100 of all the axes that are present in the board and the three lower bits have a preset configuration sends a write location signal designated by the reference numeral 11 the second counter when counted selects the first counter 6 which addresses the first element of the vector inside the memory 3 the counter 7 a register 8 and the two latch elements 5 and 6 when the signal 11 arrives if the counter 7 is equal to zero the data item pointed in the memory 3 enters the counter 7 and the counter 6 is incremented by one if instead the counter 7 is nonzero and the register 8 is empty the data item contained in the memory 3 is written to the register 8 the data item contained in the latch element 5 is written to the second latch element 6 the first counter 6 is incremented by one and the counter 7 is decremented by one finally if the counter 7 is equal to zero and the register 8 is not empty nothing happens and the system waits for the next selection related to the axis which is performed by selection of the address 1 at this point the data must be transferred to the actuators and said transfer occurs asynchronously when a.
