Turbo PMAC/PMAC2 Software Reference

Turbo PMAC On-line Command Specification 376

MFLUSH

Function: Clear pending synchronous M-variable assignments

Scope: Coordinate-system specific

Syntax: MFLUSH

This command permits the user to clear synchronous M-variable assignment commands that have been

put on the stack for intended execution with a subsequent move (without executing the commands). As

an on-line command, it is useful for making sure pending outputs are not executed after a program has

been stopped.

Examples:

Q ; Stop execution of a program

MFLUSH ; Clear M-variable stack

B1R ; Start another program; formerly pending M-variables will not execute

M{data}&={expression},

MOVETIME

Function: Report time left in presently executing move

Scope: Coordinate-system specific

Syntax: MOVETIME

MVTM

The MOVETIME command causes Turbo PMAC to report the time left in the currently executing

commanded move in the addressed coordinate system, scaled in milliseconds (at 100%). If variable Isx14

for the addressed coordinate system is set to a non-zero value, the value of Isx14 is subtracted from this

value calculated for response, the difference is converted to servo cycles, and this result is written to the

Isx11 automatic countdown timer. This additional functionality facilitates anticipating the end of the

commanded move.

This “time remaining” function is not active if the addressed coordinate system is executing moves in the

special lookahead buffer.

NOFRAX

Function: Remove all axes from list of vector feedrate axes

Scope: Coordinate-system specific

Syntax: NOFRAX

This command causes Turbo PMAC to remove all axes from the list of vector feedrate axes for the

addressed coordinate system. In this mode, any feedrate-specified move in the coordinate system will

yield a vector distance of 0, forcing the use of the Isx86 alternate feedrate. This can be useful to create a

“dry run” of a motion program, overriding the feedrates specified in the motion-program F commands.

Axes can be restored to the vector feedrate list with the FRAX command.
