• Diagnosis data related to axis synchronous control
DGN 3500 Synchronization error amount
[Data type] 2-word axis
[Unit of data] Detection unit
[Valid data range] −99999999 to +99999999
The difference in position (synchronization error amount) between the
master axis and slave axis is indicated. This data is indicated for the
slave axis.
DGN 3501 Synchronization error compensation value
[Data type] 2-word axis
[Unit of data] Detection unit
[Valid data range] −99999999 to +99999999
Cumulative value of compensation pulses (synchronization error
compensation value) output to the slave axis is indicated. This data is
indicated for the slave axis.
• Diagnosis data related to synchronous/mixture control
DGN 3502 Indication of synchronization error amount for each axis
[Data type] 2-word axis
[Unit of data] Detection unit
[Valid data range] −99999999 to +99999999
When synchronization deviation is detected (SERx of parameter No.
8162 is set to 1), the positional deviation difference of the slave axis
from the master axis is indicated.
The positional deviation difference is:
(Positional deviation of master axis) ± (positional deviation of slave
axis)
+ when mirror image is applied to
synchronization command
− when mirror image is not applied to
synchronization command
• Diagnosis data related to linear scale with absolute address reference marks
