Modal activation (FOCON/FOCOF)
The activation of the function after
POWER_ON
and
RESET
is determined by the machine

FOCON
FOCON
: Activation of the modally effective torque/force limitation
FOCOF
: Disable torque/force limitation
The modal activation acts beyond the program end.
If already programmed, it is effective with
FXST
set torque/force.
FXST
can be programmed irrespectively of
FOCON
; it comes into effect, however, only after
the function has been activated.
Programming
The programming of the axis is carried out in square brackets.
The following are permissible:
•
Geometry axis identifiers
•
Channel axis identifiers
•
Machine axis identifiers
Example:
N10 FOCON[X]
; Modal activation of the torque limit
N20 X100 Y200 FXST[X]=15
; X travels with reduced torque (15%)
N30 FXST[X]=75 X20
; Changing the torque to 75%.
; X travels with this reduced torque.
N40 FOCOF[X]
; Disable torque limit
Block-related limit (FOC)
The parts program command
FOC
activates the torque limit for a block.
An activation from a synchronized action takes effect up to the end of the current parts
program block.
