Signal
Synchronous control selection signal
SYNC1<G066#2>, SYNC2<G070#2>, ...
[Classification] Input signal
[Function] Notifies the control unit whether synchronous operation, independent
operation, or normal operation is selected under synchronous control
and twin table control.
Under synchronous control, this signal is valid only when bit 1 (SYN)
of parameter No. 1817 is set to 0.
[Operation] Depending on the combination of SYNCm and SYNCs, control is
exercised as indicated in the table below; m represents a master axis
number, and s represents a slave axis number.

*1 SYNCm may be set to 1 or 0 in manual operation under
synchronous control and twin table control.
*2 Independent master axis operation is exactly the same as normal
operation.
*3 Independent operation is not applicable in manual operation under
synchronous control and twin table control.
Synchronous control torque difference detection disable signal NSYNCA<G158#3>
[Classification] Input signal
[Function] This signal is intended to disable alarm detection when the
synchronous control torque difference alarm function being used.
[Operation] Setting this signal to 1 disables synchronous control torque difference
alarm detection.
Synchronization control positional deviation error alarm signal SYNER <F153#1>
[Classification] Output signal
[Function] This signal indicates to the outside that an alarm condition has occurred
when the synchronization error check based on positional deviation is
in use.
[Operation] The servo positional deviation for master and slave axes are monitored
during synchronization control. If the positional deviation exceeds a
limit specified in parameter No. 7799, alarm OT513 is issued, and a
synchronization control positional deviation error alarm signal
(F153.1) is set to "1".
Causing a reset clears the alarm condition, thus resulting in the signal
becoming "0".
