MACHINE PARAMETERS
SOFT: V02.2X
Axis parameters
INPREV (P87) OUTPREV (P88)
Parameters that indicate the input revolutions (INPREV) and the output revolutions OUTPREV) of
each axis. These parameters are used to deal with gear ratios on the axis. The default value for both
parameters is 0.
HPITCH (P89)
On Hirth axes, it indicates its pitch in degrees. When set to ·0·, it assumes a pitch value of 1º.
It admits values other than 1º and decimal values. When HPITCH is set with a decimal value, the
screen will show the coordinates with decimals.
Any stop or movement in continuous jog will stop the axis in coordinates multiple of HPITCH. The
incremental jog movements will be similar to the ones carried out with a 1 degree pitch.
• For incremental switch positions of 1, 10, 100 or 1000, it will move 1 step.
• For an incremental switch position 10000, the movement will be multiple of the closest pitch to
10º (and under 10º). If the pitch value is greater than 10º, it will move a single step.
Even if the position of a Hirth axis does not coincide with its Hirth pitch, any other axis may be moved
to a valid position in both automatic and jog modes. An error message will be issued if the position
to move the axis does not coincide with the pitch. In any case, it is possible to move any other axis
in both automatic and jog modes.
AXISDEF (P90)
It allows customizing the movement of the axis.
This parameter has 16 bits counted from right to left.
Each bit has a function or work mode associated with it. By default, all the bits will be assigned the
value of ·0·. Assigning the value of ·1· activates the corresponding function.
Bit 15. Rollover axis. Movement in G53 via the shortest way.
This bit indicates how the movements in G53 are carried out for a positioning-only rotary axis without
travel limits.
When set to ·1·, G53 movements are carried out along the shortest path. When several presets have
been made, the axis may rotate several complete turns.
Both axis machine parameters INPREV and OUTPREV must be 0 or both other than zero. Do not
program one with a 0 value and the other one with a value other than 0.
Possible values
Between 0 and 99999.9999 degrees.
(the remainder of 360/HPITCH must necessarily be zero)
