Precautions When Using C500-NC222-E in NC221 Mode
Section 1-7
There will be no timing errors if the C500-NC222-E in NC221 mode and the
C500-NC221-E are in correct timing control operation, which however, does
not mean that there is no difference in tact time between the C500-NC221-E
and the C500-NC222-E in NC221 mode.
Change in Tact Time
A
There is no difference in movement range between the C500-NC222-E in
NC221 mode and the C500-NC221-E. The period A, which is the value left
over by the internal operation of the C500-NC222-E in NC221 mode as
shown in the above timing chart on the right hand side, however, may be
produced. The difference in tact time is caused by the period A, which can
be, however, solved by adjusting the speed data or movement range of the
C500-NC222-E.
3. Parameter Settings Before Shipping
The parameters of the C500-NC222-E are factory-set so that the
C500-NC222-E can be used in NC222 mode. NC221 and NC222 mode
parameters share the same area of the C500-NC222-E. Therefore, before
using the C500-NC222-E in NC221 mode, be sure to change the parame-
ters. Refer to the following table for the differences between NC221 and
NC222 mode parameters.
