Command
set_fly_x
Function Activates Processing-on-the-fly correction for compensation of a linear workpiece-
movement in the x direction (based on position values transferred to the RTC6 by encoder
counter “Encoder0”) and sets the corresponding scaling factor.
Restriction If the Option Processing-on-the-fly is not enabled, then set_fly_x terminates the
Processing-on-the-fly process (even though it could not have been activated).
Call set_fly_x( ScaleX )
Parameters ScaleX Scaling factor for the x direction (encoder counter “Encoder0”).
In bits/count.
As a 64-bit IEEE floating point value.
Allowed value range: 1/256  | ScaleX |  16000.0.
Comments • ScaleX can be negative depending on the motion direction of the workpiece. The
restricted value range applies only to the absolute value.
• For Processing-on-the-fly correction and determination of the scaling factor, see
Chapter 8.6 ”Processing-on-the-fly”, page 242.
• If unallowed parameter values are supplied (for example, for ScaleX = 0), then
set_fly_x does not activate a Processing-on-the-fly correction or deactivates a
Processing-on-the-fly correction previously activated by set_fly_x (but does not
deactivate any other Processing-on-the-fly correction). The latter case leads to a jump
(at jump speed) to the endpoint of the most recently executed Vector Command or
“Arc” Command (without “set_fly_x“ Processing-on-the-fly correction).
• The various Processing-on-the-fly corrections cannot be arbitrarily combined, see
Section ”Overview”, page 242.
• For deactivating Processing-on-the-fly correction, see Chapter 8.6.5 ”Deactivating
Processing-on-the-fly Correction”, page 251.
• By set_control_mode( Bit #9 ), it can be set in advance when the encoder counter
“Encoder0” is reset by set_fly_x.
• You can also switch on set_fly_x/set_fly_y Processing-on-the-fly correction by
activate_fly_xy/activate_fly_xy_encoder.
RTC4RTC6 Unchanged functionality. In addition: changed value range.
In RTC4 Compatibility Mode, the RTC6 multiplies the specified value for ScaleX by 16.
The allowed value range decreases accordingly.
RTC5RTC6 Unchanged functionality.
Version info Available as of DLL 600, OUT 600, RBF 600.
