1. AXIS CONTROL
53
NOTE
If the synchronization error check function is not used, set
parameter 8314 to 0.
If the agreement between the positions of the master and slave axes is lost
when the system power is turned off, the function compensates for the
difference between them. After performing a follow–up at power on, the
function sends compensation pulses to the slave axis to adjust its position
such that it agrees with that of the master axis. This function is enabled
only when the slave axis of synchronization control supports the
absolute–position detection function.
This function, however, cannot be used for rotation axes.
WARNING
1 The synchronization compensation function is enabled
after reference position returns have been performed. The
function is not executed if the parameter is set before
reference position returns are performed.
2 The synchronization compensation function is not executed
when the servo alarm is eliminated.
CAUTION
The synchronization deviation is processed as a position
error on the slave axis while at rest. The position error is
displayed as diagnostic data 300, in the same units as used
to detect the error. If the error exceeds the value set in
parameter 8315, servo alarm 410 is triggered. The alarm
can be cleared by pressing the reset key. As the position
error for the slave axis remains even after the alarm is
cleared, however, the positions must be adjusted.
NOTE
1 To use the synchronization compensation function, set the
SOF bit, bit 7 of parameter 8301.
2 The synchronization compensation function is also enabled
when emergency stop is canceled.
