activate_fly_1_axis
Function “Fly Extension” Command: Activates a 1 Axisn-Processing-on-the-fly application.
Restriction If the Option Processing-on-the-fly is not enabled, then activate_fly_1_axis terminates the
Processing-on-the-fly process (even though it could not have been activated).
Call activate_fly_1_axis( Axis, Mode, Scale, Offset )
Parameters Axis Axis from Table 3, page 259.
As an unsigned 32-bit value.
Allowed values: 1 … 2 .
Mode Mode from Table 4, page 261.
As an unsigned 32-bit value.
Allowed values: 1…4.
Scale Scaling factor.
As a 64-bit IEEE floating point value.
Allowed value range:
• 1/256  | Scale |  16.000,0 with linear axis ( 1 or 2 )
Scale can be + or –. Only the absolute value is restricted.
Offset Offset to the encoder value.
As a signed 32-bit value.
Comments • Being an “Fly Extension” Command, activate_fly_1_axis must not be used mixed with
“Classic“ Processing-on-the-fly commands (see Footnote, page 242).
• See Chapter 8.6 ”Processing-on-the-fly”, page 242 and Section
”“Fly Extension” Commands”, page 259.
• activate_fly_1_axis occupies two RTC6 List Memory positions.
• activate_fly_1_axis requires two 10 µs clock cycles for execution.
• At the specified Axis 1 , neither a Processing-on-the-fly correction nor a rotation
correction must be active. However, the Axis can be combined as a linear axis with the
third linear axis.
• An xy positioning stage compensation is automatically executed, if after the successful
activate_fly_1_axis execution Axis 1 and Axis 2 are activated with two physically
different encoder modes (for example, Mode 1 and 3 mean the same physical encoder)
and xy positioning stage compensation is defined and activated (see
load_fly_2d_table), then xy travel table compensation is automatically executed.
• With an unallowed parameter value, activate_fly_1_axis is replaced by a list_nop
(get_last_
error return code RTC6_PARAM_ERROR ).
• See also comments on activate_fly_2_axes.
