greater than the value set in parameter No. 7723, an OT513 alarm is
issued, and the machine is stopped.
This function can check for the machine position shift that can occur
when servo position control is turned off as in the case of an emergency
stop, servo alarm, or servo off.
When the input signal is used to switch between synchronous operation
and normal operation, a synchronous error check is made even in
normal operation. So, even if the synchronous control selection signal
(SYNCx) is set to 0 by mistake during synchronous operation, damage
to the machine can be avoided.
Synchronization error check based on positional deviation
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 output.
Alarm OT513 is issued for both master and slave axes.
