4. CONVERSATIONAL MACRO FUNCTION
B–62073E–2/03
82
change command is performed. It is set to 100% when turning on the
power.
(3) Caution
1) Command buffering
Buffering of command block is performed on CNC side in order to
continuously carry out multiple commands in the axis control
function by PMC. Namely, even if one block is being executed, if
there is a vacancy in CNC buffer it is possible to perform the next
command. However, note that when there is no vacancy in CNC
buffer, the previous block command completes until a vacancy occurs
in the buffer because wait state occurs inside the command.
As commands are stored in the buffer when G3** is executed, (1)
PMCAx described on the previous page is not needed.
2) Auxiliary command function
Commanding an auxiliary function is possible by G346, but the
auxiliary function complete signal FINnX cannot be controlled in the
conversational macro. Control it by the PMC.
3) Conflict of axis control functions by original PMC
Never perform commands from both the PMC and this function for
the same PMC controlaxis. For the PMC control axis to be used by
this function, control in the PMC by only the auxiliary function
complete signal ”FINnX”.
4) Data units
Command the shift amount to be commanded by address X (dwell
amount), and feed rate to be commanded by address F in the
minimum setting units.
The specified value of the torque lilmit override can be changed by setting
a value in the range #8990–#8992. Further, reading the torque limit
override value to #8992 by setting a value to #8990, #8991.
