(corresponding to the
measuring direction)
DFA
TSA
By specifying the measuring axis in parameter measuring direction, then all 3 measuring planes are possible. Setpoint
1)
angle α therefore refers to the positive direction of the offset axis and is negative in the clockwise sense, positive in the
counterclockwise sense.
Setpoint angle α specifies the required angle between the edge and the positive direction of the offset axis. For α=0
( ), after correction, regarding the offset axis, the edge is parallel to the axis.
S_STA=0
When positioning "parallel to the edge", angle α is also used for positioning. The positioning angle is generated together
with parameter TSA. Parameter α should therefore only deviate a small amount from the measured angle!
Parameter L2 ( ) is used to define the distance in the offset axis between P1 and P2. Only positive values are

S_ID
permissible for L2. Accordingly, P1 should be selected in the offset axis at the beginning of the cycle.
Other parameters and correction targets can be set in the general SD 54760 $SNS_MEA_FUNCTION_MASK_PIECE.
3)
To display the corresponding rotary axis as offset target, bit 6 must be set to 1 in the channel-specific MD 52207

$MCS_AXIS_USAGE_ATTRIB.
