6.11.16 Speed control
Speed control is used to move endlessly in the same direction; for example, a
conveyer or a carrying machine.
Normally, in speed control, the current value does not change regardless of the
forward run or the reverse run, and it does not stop until the stop instruction comes.
However, if "1" is set to the current feed value update request command in the detailed
parameter (1) (buffer memory address 30/180/330/480), the current value increases or
decreases.
This demonstration machine with the upper/lower limit switch automatically stops at
that position.
