2.5.13 Software axis limits.
LIMIT+
Positive software limit.
Parameter valid for linear and rotary axes.
Parameter valid for analog drive, Sercos and simulated.
Possible values (1): Within ±99999.9999 mm.
Possible values (2): Within ±3937.00787 inch.
Possible values (3): Within ±99999.9999 degrees.
Default value: 99999.9999 mm / 3937.00787 inch / 99999.9999 degrees.
Associated variable: (V.)[ch].MPA.POSLIMIT.xn
See axis machine parameters LIMIT-.
LIMIT-
Negative software limit.
Parameter valid for linear and rotary axes.
Parameter valid for analog drive, Sercos and simulated.
Possible values (1): Within ±99999.9999 mm.
Possible values (2): Within ±3937.00787 inch.
Possible values (3): Within ±99999.9999 degrees.
Default value: -99999.9999 mm / -3937.00787 inch / -99999.9999 degrees.
Associated variable: (V.)[ch].MPA.NEGLIMIT.xn
On rotary axes, the CNC takes this parameter into account when AXISMODE = Linearlike.
On linear and rotary axes, these parameters set the axis travel limits. If both are set to "0",
there will be no software limits.
SWLIMITTOL
Software limit tolerance.
Parameter valid for linear and rotary axes.
Parameter valid for analog drive, Sercos and simulated.
Possible values (1): Within ±99999.9999 mm.
Possible values (2): Within ±3937.00787 inch.
Possible values (3): Within ±99999.9999 degrees.
Default value: 0.1000 mm / 0.00394 inch / 0.1000 degrees.
Associated variable: (V.)[ch].MPA.SWLIMITTOL.xn
This parameter indicates the maximum variation or oscillation allowed for an axis located
at the limit.
This parameter indicates the maximum variation or oscillation allowed to a real coordinate
of an axis referred to the software limits, before issuing an error indicating travel limit overrun.
The programmed theoretical movement of the axis is only possible up to the exact limit, but
the real axis coordinate is allowed this margin before the error is issued.
When they are DRO axes, the error is also issued when the real coordinate exceeds the limit
over the tolerance.
When no theoretical movement has been programmed, the limit overrun error will only be
issued when exceeding the tolerance in a sampling period (cycle time); for example, when
hitting the axis causing it to overrun the limits abruptly. In any other case, if no theoretical
movement has been programmed for the axis, the error will not be issued even if it overruns
the limits.
The software limits are always set in radius, regardless of the setting of parameter DIAMPROG.
