Description:
1: "Modulo 360 degrees" position display is active:
The position display of the rotary axis or spindle (for basic or machine
coordinate system) is defined as "Modulo 360 degrees". In the case of a pos-
itive direction of rotation, the control resets the position display inter-
nally to 0.000 degrees following each cycle of 359.999 degrees. The display
range is always positive and lies between 0 and 359.999 degrees.
0: Absolute position display is active:
In contrast to the modulo 360 degrees position display, absolute positions
are indicated by the absolute position display, e.g. +360 degrees after 1
rotation, and +720 degrees after 2 rotations, etc in the positive direction.
In this case, the display range is limited by the control in accordance with
the linear axes.
MD irrelevant for:
Linear axes MD30300 $MA_IS_ROT_AX = "0"
Related to:
MD30300 $MA_IS_ROT_AX = 1 "Axis is rotary axis"
Description: Defines the size of the modulo range. Default positions are accepted and dis-
played within this range. Useful modulo ranges are n * 360 degrees with inte-
ger n. Other settings are equally possible in principle. Attention should be
paid to having a useful relationship between the positions in the NC and the
mechanics (ambiguity). Velocity definitions are not affected by settings in
this MD.
Description: Defines the start position for the modulo range.
Example:
Start = 0 degree -> modulo range 0 <->360 degrees
Start = 180 degrees -> modulo range 180 <->540 degrees
Start = -180 degrees -> modulo range -180 <->180 degrees
