Example:
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.
Priority FXS/FOC
An activation of FXS with
FOC
active has priority, i.e.
FXS
is executed.
A deselection of FXS will cancel the clamping.
A modal torque/force limitation remains active.
After
PowerOn
the activation takes effect with the machine data:
MD37010 $MA_FIXED_STOP_TORQUE_DEF.
This torque can be modified at any time by programming
FXST
.
Synchronized actions
The language commands
FOC
,
FOCON
,
FOCOF
can also be programmed in synchronized actions as the
commands for "travel to fixed stop."
Determine FOC status
The activation status can be read at any time via the status variable $AA_FOC.
If
FXS
is also activated, the status is not changed.
Determine torque limit status
The system variables $VA_TORQUE_AT_LIMIT can be used at any time to read in systems whether the
currently active torque corresponds to the given torque limit.
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
0:
FOC
not active
1:
FOC
modal active
2:
FOC
block-related active
0: Effective torque less than torque limit value
1: Effective torque has reached the torque limit value
