1.AXIS CONTROL B-63943EN-1/02
- 260 -
CAUTION
1 Retraction is performed at the speed specified in
parameter No. 7740.
2 Feed hold is not effective to movement during
retraction.
3 Feedrate override is not effective to movement
during retraction.
4 The delay of the cancellation of synchronization on
the EGB axis with parameter No. 7717 is not
effective in the following cases:
1) If a servo alarm is generated on the axis on
which EGB synchronization is performed.
2) The activation of the axis that shares the
amplifier with the axis on which EBG
synchronization is performed is turned off due to
a servo alarm and so on.
NOTE
1 During a retract operation, an interlock is effective
to the retract axis.
2 During a retract operation, a machine lock is
effective to the retract axis. The retract operation
terminates in the machine lock state, and a retract
completion signal is output.
3 If, during automatic operation, the retract signal is
set to "1", a retract operation is performed and the
automatic operation is halted.
4 During retraction, automatic operation cannot be
performed.
If a cycle start is performed, the warning "START
REJECT(RETRACT EXECUTING)" is displayed.
5 Retract movement is performed with non-linear
type positioning.
6 To enable the retract function with a servo spindle
alarm, ART, bit 3 of parameter No.7702, must be
set.
7 After the end of retraction with a servo alarm, servo
position control stops in 400 ms.
8 The retract completion signal, RTRCTF, becomes
"0" when a move command is issued for any axis
after retract operations on all axes are completed.
