The MC Unit can perform up to two tasks. (A task is a unit of execution for a pro-
gram.)
By executing two tasks at the same time, the MC Unit can perform the same
functions as done by two NC controllers.
The number of tasks and axes to be used are set in advance using the MC Sup-
port Software by editing unit parameters.
The X axis and Y axis are available. Each axis can be used in only one task, i.e.,
any axis assigned to one task cannot be used for another task.
Task 1 :
X axis
The MC Unit is capable of storing a total of 800 blocks of programming. The max-
imum number of blocks that can be executed in each task depends on the num-
ber of tasks as shown in the following table. These figures include subprograms.

The maximum of 100 programs can be managed by the MC Unit. The number of
programs that can be managed per task depends on the number of tasks as
shown in the following table. These figures include subprograms.

Note 1. Each program number can be used only once; the same program number
cannot be used in a different task.
