Caution

1)A maximum point number (specified by the settings of SV.Pr57 (selection of number of input points)) is treated as the “Single” operation, regardless of the block setting.

2)The change into the last point number (point “10” in this example) of the in-operation signal output (BUSY: CN X5 Pin 28) and the current position output (P1OUT to P32OUT: CN X5 Pin 29, 30, 31, 32, 33 and 34) is made only when the last step operation of the continuous block operation has completed and the strobe signal input (STB: CN X5 Pin 24) is in the OPEN state. Be sure to make the strobe signal input (STB) open after the in-operation signal output (BUSY) turns OFF.

Combined Block Operation

If the block setting of a point number specified by the point specifying input (P1IN to P32IN: CN X5 Pin 3, 4, 5, 6, 7 and 8) is “Block” when 16.Pr54 (block operation type setting) is “1” (combined block operation), the operation which consists of combined step operations from a specified point number to the “Single” point number specified by the block setting.

An operation does not stop and the ￿

speed changes from VEL1 into VEL2.
