15. PMC CONTROL FUNCTION
B–63503EN–1/01
730
CAUTION
The specified feedrate can be magnified by 1, 10, or 100 by
setting bits 6 (FR1) and 7 (FR2) of parameter No. 8002
accordingly.
(10) External pulse synchronization – main spindle
(EC0g to EC6g: 0Bh)
(11) External pulse synchronization – first manual handle
(EC0g to EC6g: 0Dh)
(12) External pulse synchronization – second manual handle
(EC0g to EC6g: 0Eh)
(13) External pulse synchronization – third manual handle
(EC0g to EC6g: 0Fh)
For these commands, the signals are used to specify the weight of the
external pulses. A weight range of "1/256 to "127 can be set by using
signals EIF0g to EIF7g for the figures after the decimal point. When a
negative weight is specified, the tool is moved in the reverse direction.
When a new pulse weight is specified while the tool is moving in
synchronization with external pulses, inverting signal EBUFg causes the
tool to move with the new pulse weight.
As commands for (10) to (13) are executed without buffering, axis control
command read completion signal EBSYg usually need not be checked.
CAUTION
The pulse weight is clamped according to the value set for
parameter No. 1424 (parameter for the manual rapid
traverse rate for each axis).
NOTE
When diameter programming is specified with bit 3 (DIAx)
of parameter No. 1006, bit 1 (CDI) of parameter No. 8005
can be used to specify whether a radius or diameter is to be
used in a command (T series).
(14) Continuous feed (EC0g to EC6g: 06h)
Set the feedrate as the same as for cutting feed – feed per minute
(EC0g to EC6g: 01h). The feedrate can be changed during
continuous feed.
Specify the feedrate with signals EIF0g to EIF15g, and invert the
axis control command read signal EBUFg during continuous feed,
then the tool moves at the new feedrate.
As commands for jog feed are executed without buffering, axis
control command read completion signal EBSYg usually need not
be checked.
The specified feedrate can be magnified by 10 by setting bit 3 (F10)
of parameter No. 8002, and by 200 by setting bit 2 (JFM) of
parameter No. 8004.
