15. PMC CONTROL FUNCTION
759
CAUTION
1 Emergency stop or machine lock is enabled. Machine lock
can be disabled if the MLE bit (bit 0 of parameter No. 8001)
is specified accordingly. However, machine lock for an
individual axis is always enabled.
2 In consecutive cutting feed blocks, a new block starts its
operation without waiting for the following zero of the servo
acceleration/deceleration. In other than the above blocks,
a new block starts its operation after the following zero of the
servo acceleration/deceleration is confirmed.
3 Commands for a linear axis that is controlled solely by the
PMC (not used as an axis controlled by the CNC) are not
affected by inch/metric input if the PIM bit (bit 0 of parameter
No. 8003) is specified accordingly. The current position
display, also, is not affected by inch/metric input.
4 For a PMC–controlled axis, manual absolute mode is
always set. If the PMC starts control of an axis after manual
intervention (manual continuous feed, manual handle feed,
etc.) is performed during automatic operation while manual
absolute mode is not set (*ABSM is set to 1), manual
absolute mode is set.
5 Under PMC axis control, all commands are handled as axis
commands. Even for the miscellaneous function, the
position check is effective.
6 When the CNC specifies the command of workpiece
coordinate system setting (G54 to G59) during an axial
movement by the PMC, a correct coordinate system cannot
be set.
NOTE
1 The actual speed excluding the effect of the movement
along a PMC–controlled axis can be displayed if the PCF bit
(bit 1 of parameter No. 3105) is specified.
2 If an absolute pulse coder is used, a specified reference
position is retained in memory, even after the power is
turned off.
3 If the index table indexing function of the M series is used,
the PMC cannot control the fourth axis.
4 The individual output of the miscellaneous function is
provided by adding a signal for individual output. The timing
diagram of controlling and specifying the miscellaneous
function is not changed. The normal specifications of the
miscellaneous functions for PMC axis control function are
applied.
