4.5 Modulo or Limited Excursion Rotary Axes P1
Description
4 - 12 en-938818/7
Category Axis declaration
Type 6 32-bit hexadecimal
No. of words 2
Declares rotary axes as modulo 360 degrees or limited excursion type.
Principle
The bit position gives the physical axis address.
Word N0: Modulo 360 degrees rotary axes.
A rotary axis is modulo if the value of the current position returns to zero after rotating by 360 degrees. The travel of
a modulo rotary axis is not limited by software stops.
The bit is a 1 to declare the rotary axis as modulo.
Word N1: Limited excursion rotary axes.
A rotary axis with limited excursion is an axis controlled like a linear axis.
Axes with limited excursion are axes:
- with an excursion less than 360 degrees with respect to a reference position (twist head),
- that it is desired to control over several revolutions.
The bit is a 1 to declare the rotary axis with limited excursion.
! CAUTION
Only rotary axes (modulo or limited excursion) with axis names A, B or C can be assigned
to a programmed group.
REMARKS: Axes declared in both lists cannot be programmed in inches and cannot be assigned
a scaling factor.
If an axis is declared modulo and with limited excursion, it is considered modulo by
the system.
