SYNCHRONIZATION
CORRECTION MODE
[Function]
When the OPERATION ERROR 51 (Synchronization error too large) occurs, the occurring error is
corrected without changing the operation method with this mode.
[Operation]
In the correction mode, the operation is as follows.
(1) Synchronous control is not carried out even for the synchronous axis, and the basic axis and
synchronous axis are handled as two independent axis by each control section. Thus, basic
axis and synchronous axis can be move moved individually.
(2) If the zero point has established, the synchronization error check is carried out.
(3) If the correction mode switch is turned ON during selecting the mode except the handle or
manual random feed mode, the OPERATION ERROR 120 (Synchronization correction mode
ON) will occur.
In the handle or manual random feed mode, if the correction mode switch (1st part system: Y722,
2nd part system: Y802 ... 7th part system: YC62) is turned ON, the correction mode can be set and
"CORRECTION MODE" will be displayed in the operation mode display position.
The operation procedure is shown below.
Select the handle or manual
random feed mode.
Select the axis to be moved
between the basic axis and
synchronous axis.
