PITCHB (P86)
Leadscrew pitch.
This parameter must only be set when using CAN servo system. When not using CAN servo system,
the leadscrew pitch is defined with parameter PITCH (P7).
When using gear reduction on the shaft, only the whole assembly must be taken into account when
setting one of parameters PITCHB or NPULSES.
INPREV (P87) OUTPREV (P88)
Parameters that indicate the input revolutions (INPREV) and the output revolutions (OUTPREV) of
each axis. These parameters are used to handle the gear ratios on the axes. 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 continuous jog movement 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.
When using CAN servo, if both parameters NPULSES and PITCHB are set to ·0·,
the CNC will assume the equivalent values of the drive.
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.
