9.4.41 Continue synchronism
The “Synchronism“ function can be temporarily deactivated at U674.1
via disable/enable or call-up in the mode manager. Previously internal
values/statuses of synchronism were reset in the process.
If the new function "Continue synchronism" is activated via binector
input U674.2 the internal values/statuses are frozen. No internal reset
of values/statuses takes place. Thus when synchronism is temporarily
deactivated it behaves as if it had never been shut down.
The new bit 23 in the synchronism status word n450./ KK0800 and the
binector 826 in function diagram 846 shows the activation of the
“Continue synchronism” function.
During deactivation the synchronism output KK0310 is tracked to the
position setpoint value output at U671, i.e. in the factory setting to
actual position value KK0120.
During deactivation neither the master axes nor the slave axes may
move in order to ensure that the transmission characteristics of the
gearbox implemented via synchronism remain.
If, however, the master or slave axes do move, synchronism to the
reference value can take place again (via the existing synchronizing
functions with window evaluation).
Thus when the “Continue synchronism“ function is active the following
statuses remain:
♦ Table does not return to X0.0
♦ Synchronous status
♦ Referenced status
♦ Engage/disengage coupled
♦ Synchronization, offset angle setting [FD 841] are continued
♦ Position correction, referencing [FD 841] are continued
