B–63610EN/01
344
To establish reversed synchronization when using the third axis as
the master axis and the fourth axis as the slave axis, set parameter
No.8311 and parameter No.8312 as follows:
Parameter No.8311 (first axis) = 0
Parameter No.8311 (second axis) = 20
Parameter No.8311 (third axis) = 0
Parameter No.8311 (fourth axis) = 0
Parameter No.8312 (first axis) = 0
Parameter No.8312 (second axis) = 0
Parameter No.8312 (third axis) = 0
Parameter No.8312 (fourth axis) = 100
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 IS–C Units
Millimeter machine 0.01 0.001 0.0001 mm
Inch machine 0.001 0.0001 0.00001 inch
Rotation axis 0.01 0.001 0.0001 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.
