Hirth axis.

HIRTH
Axis with Hirth toothing.
Parameter valid for linear and rotary axes.
Parameter valid for analog drive, Sercos and simulated.
Possible values: Yes / No.
Default value: No.
Associated variable: (V.)[ch].MPA.HIRTH.xn
A Hirth axis is the one that can only be positioned at positions multiple of a given value. Even
if the position of a Hirth axis does not coincide with its pitch, the axis may be moved to a valid
position in both automatic and jog modes. If the position to move the axis does not match
its pitch, the CNC will issue an error message.
HPITCH
Hirth axis pitch.
Parameter valid for linear and rotary axes.
Parameter valid for analog drive, Sercos and simulated.
Possible values (1): From 0 to 99999.9999 mm.
Possible values (2): From 0 to 3937.00787 inch.
Possible values (3): From 0 to 99999.9999 degrees.
Default value: 1 mm / 0.03937 inch / 1 degree.
Associated variable: (V.)[ch].MPA.HPITCH.xn
When the axis is set as Hirth axis, this parameter indicates its pitch. Parameter REFVALUE
will be taken as initial coordinate for the next increments.
Any stop or movement in continuous jog will stop the axis in coordinates multiple of HPITCH.
Movements in incremental jog will only be valid if they are greater than HPITCH and will be
limited to multiples of this value. The positions of the switch for jog movements may be
customized at the axis parameter table so they match the desired steps.
The way the decimals of a Hirth axis will be displayed on the screen will be configured using FGUIM.
