– Interlock
– Feed hold
– Machine lock
3) The EGB synchronization should be started and canceled at the stop
of the master and the slave axis. It means that the tool axis (master
axis) rotation should be started while the synchronization mode
signal SYNMOD<F065#6> is “1” (Refer to Fig.2.3 Example timing
for starting/canceling synchronization). If the tool axis (master axis)
starts to rotate before the synchronization mode signal
SYNMOD<F065#6> is “1”, the synchronization does not perform
correctly.
4) Reference position return of Cs contouring control axis for master and
slave axis should be performed before G81 is specified. In the
synchronization mode, reference position return cannot be
performed. Do not change to reference position return mode in the
synchronization mode.
5) In case that the parameters for axis setting (No.7710,7771,4352) are
not set correctly, P/S alarm (No.010) occurs when G81 specified.
6) When G28/G27/G29G30/G30.1/G53 is specified in the synchronization
mode, P/S alarm (No.184) occurs. G28/G27/G29/G30/G30.1/G53
should not be specified in the synchronization mode.
7) During HPCC mode with RISC, the high–speed cycle cutting, the
high–speed liner interpolation, the high–speed remote buffer A, the
high–speed remote buffer B of DNC operation, and AI contour
control, this function is not available.
8) The slave axis position display is updated by synchronous pulse as
follows :
– Machine position display is updated.
– Absolute position display and relative position display are not
updated. When the synchronization is canceled, the pulses of the
synchronization are added to the absolute position display of the
slave axis.
9) The rotation direction of the workpiece axis depends on the rotation
direction of the tool axis. That is, when the rotation direction of the
tool axis is positive, the rotation direction of the workpiece axis is also
positive; when the rotation direction of the tool axis is negative, the
rotation direction of the workpiece axis is also negative. However, by
specifying a negative value for L, the rotation direction of the
workpiece axis can be made opposite to the rotation direction of the
tool axis.
10)During synchronization, a move command can be programmed for
the workpiece axis. Note, however, that incremental command
programming for cutting feed must be used to specify the workpiece
axis move command.
11)The synchronization mode is canceled by servo alarm, spindle alarm,
P/S alarm (No.000), or emergency stop.
12)The synchronization is not maintained in servo off status of the slave
axis.
13)When the EGB control is used, the drilling canned cycle cannot be
used.
14)The actual feedrate is displayed without the flexible synchronous
pulse.
