Direction of rotation: TRANSMIT_ROT_SIGN_IS_PLUS
TRANSMIT must be informed of the rotary axis direction of rotation with the following
machine data:
● The rotary axis direction of rotation with regard to TRANSMIT is positive if the rotary axis
● The rotary axis direction of rotation with regard to TRANSMIT is negative if it rotates
Figure 6-1
$MC_TRANSMIT_ROT_SIGN_IS_PLUS_<t> = <direction of rotation>
with t = 1, 2
<Direction of rotation>
Position of tool zero: TRANSMIT_BASE_TOOL
The position of the tool zero is specified in relation to the origin of the effective Cartesian
coordinate system for TRANSMIT:
● MD24920 $MC_TRANSMIT_BASE_TOOL_<t>[ 0 ] = <offset in X>
● MD24920 $MC_TRANSMIT_BASE_TOOL_<t>[ 1 ] = <offset in Y>
● MD24920 $MC_TRANSMIT_BASE_TOOL_<t>[ 2 ] = <offset in Z>
with t = 1, 2

rotates counterclockwise in relation to the X/Y plane looking at the X axis, when
traversing in the positive direction.
clockwise when traversing in the positive direction
Positive direction of rotation
Negative direction of rotation
Rotary axis direction of rotation
Meaning
0
Negative rotary axis direction of rotation ⇒ internal sign reversal
1
Positive rotary axis direction of rotation ⇒ no internal sign reversal
