6. C–AXIS CONTROL
119
CAUTION
For C–axis synchronization control, two servo motors are
used: one for the C
1
–axis and the other for the C
2
–axis. This
means that for the C
1
–axis and C
2
–axis, the same values
must be set in the parameters (for setting a feedrate, time
constant, and so forth) provided for each axis. If different
values are set, normal synchronous operation cannot be
expected.
For the following parameters, however, different values can
be set for the C
1
–axis and C
2
–axis:
Grid shift (No. 1850)
Backlash compensation (Nos. 1851, 1852, 16390 to 16429)
C–axis offset (No. 16430 to 16469)

4603 C AXIS SYNCHRONOUS
ERROR
The difference between the posi-
tion deviation value of C
1
axis and
C
2
axis exceeds the parameter
value (No. 16364, 16365) with the
C–axis synchronous control func-
tion.
4605 NEED ZRN The C axis synchronization is not
done normally.
