05.91 4 Programming of Motion Blocks
4.2.14 Freezing of length compensation, zero offset and angle of rotation of coordinate rotation G175/G176
4.2.14 Freezing of length compensation, zero offset and angle of
rotation of coordinate rotation G175/G176
The "Freezing of length compensation, zero offset and angle of rotation of coordinate rotation"
function reduces the block change times.
Activation of function:
G176: Freeze length compensations, zero offsets and angles of rotation of coordinate
rotation
G175: Update length compensations, zero offsets and angles of rotation of coordinate
rotation
Alarms:
3220: “Change G176 G175”
3006: “Incorrect block structure”
issued in the event of incorrect programming in conjunction with G176
3007: “Setting data programming error”
Behaviour with different G function/D function combinations
Condition: G176 active
N020 G54...G57
N030 D . . .
N040 G58/59 . . . A
N050 G53
Change to G175 plus alarm 3220
Block: G176 G54...G57
G176 D . . .
G176 effective. Freezing is effected.
Block: G176 G58/59
Special effect owing to setting data G58/G59 plus alarm 3007
Block: G176 G53
Change to G175 plus alarm 3006
While G176 is active modifications of the "external zero offsets from the PLC" are not
processed and do not invoke alarm displays. The writing of tool offsets, angle of rotation, zero
offset, DRF, PRESET and suppression of zero offset by means of the functions @706, @42x
and @43x is not allowed.
