[Function]
When this simulation is executed, the currently set value is displayed.
Enter the adjustment value with [ ] [ ] key (or [Numeric] key for the AL-2050/2060) and press
[OK]/[START] key. The entered value is stored and the machine goes into the sub code entry
standby mode. The greater the set value is, the higher the speed is. The smaller the set value
is, the lower the speed is.
