Synchronization for EGONSYNE
With EGONSYN(), the positions of the leading axes and the synchronization position for the
following axis are specified by the command.
The control system moves the following axis to the synchronized position according to the
program approach mode.
Synchronization abort with EGONSYN and EGONSYNE
1. The EGONSYN/EGONSYNE command is aborted under the following conditions and
• RESET
• Axis switches to tracking
The defined synchronization positions are ignored. Synchronous traverse monitoring still
takes synchronized positions into account.
Aborting position synchronization generates alarm 16774.
The alarm may be suppressed with the following machine data:
MD11410 $MN_SUPPRESS_ALARM_MASK Bit31 = 1

the following axis are specified by the command.
the specified synchronization position so that the following axis is in position with the
leading axes at its synchronization position.
for the following axis, the following axis is not set in motion by EGON or EGONSYN. A
travers command is issued and block changing is blocked until the axis-specific feed is
enabled. EGOSYN is topped by RESET transformed into EGON. The programmed
synchronized positions are deleted.
DBX4.3 has no direct influence on the electronic gearbox. As before, it does have an
indirect effect on the leading axes, if these are located in the same channel. .
has no direct influence on the electronic gearbox. The axis-specific feed enable is set,
depending on the current override setting.
