B–64160EN/01
158
Example2:Simple synchronous control is exercised with two pairs.
Assume that the following three pairs are to be used:
The master axis is the first axis, while a slave axis is the fouth axis.
The master axis is the second axis, while a slave axis is the third
axis.
For this specification, set this parameter as follows:
Parameter No.8311 X (First axis) = 0
Y (Second axis) = 0
Z (Third axis) = 2
(Fourth axis) = 1
NOTE
1 In Example 2 above, the Z axis, which is the master axis, is
used as the slave axis of another axis. This usage may
prevent other functions from operating normally. When
exercising simple synchronous control with two pairs, take
care.
2 The axis number of a master axis must always be smaller
than the corresponding slave axis number. Multiple slave
axes cannot be assigned to a master axis.
8313
Limit of the difference between the amount of positioning deviation of the master
and slave axes (Synchronous control one pair)
[Data type] Word
[Unit of data] Detection unit
[Valid data range] 0 to 32767
Set the limit of the difference between the amount of positioning
deviation of the master and slave (fourth) axes. If the difference between
them exceeds the limit assigned to the parameter, the P/S alarm (No.213)
is activated.
8314 Maximum error in synchronization error check
[Data type] Word axis
[Unit of data]
Increment system IS–A IS–B Units
Millimeter machine 0.01 0.001 mm
Inch machine 0.001 0.0001 inch
Rotation axis 0.01 0.001 deg
[Valid data range] 0 to 32767
The machine coordinates on a master axis and slave axis are monitored. If
a difference (synchronization error) which is greater than the value
specified in this parameter is detected, a servo alarm (No.407) is
generated, and the machine is stopped.
Set this parameter with a master axis. When 0 is set in this parameter, no
synchronization error check is made.
