Normal
List Command set_fly_y
Function activates Processing-on-the-fly correction for compensation of a linear workpiece-
movement in the Y direction (based on position values transferred to the RTC
®
5 via
encoder counter Encoder1) and sets the corresponding scaling factor. Encoder counter
Encoder1 may be reset (see comments).
Restriction If the Processing-on-the-fly option is not enabled, then the command terminates the
Processing-on-the-fly process (even though it couldn’t have been activated).
Call
set_fly_y( ScaleY )
Parameter
Scale
scaling factor for the Y direction (encoder counter Encoder1) in bits/count
(as a 64-bit IEEE floating point value);

Comments • For Processing-on-the-fly correction and determination of the scaling factor, see
"Processing-on-the-fly (Optional)", page 177 .
• If unallowed parameter values are supplied (e.g. for
ScaleY
= 0), then set_fly_y will not
activate a Processing-on-the-fly correction or will deactivate a Processing-on-the-fly
correction previously activated via
set_fly_y (but will 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 or arc command (without “
set_fly_y “
Processing-on-the-fly correction).
• The various Processing-on-the-fly corrections can’t be arbitrarily combined (see the
page 178 ).
• For deactivating Processing-on-the-fly correction, see page 186 .
• Via set_control_mode , bit#9 can be set in advance to specify whether encoder counter
Encoder1 should reset immediately via set_fly_y or only after the subsequent external
start trigger (i.e. via the subsequent external start signal or simulate_ext_start or
simulate_ext_start_ctrl command, possibly postponed by a track delay set via
simulate_ext_start , set_ext_start_delay or set_ext_start_delay_list ; also see
set_control_mode , bit#2).
• You can also switch on set_fly_x / set_fly_y Processing-on-the-fly correction via the
activate_fly_xy command.

RTC
®
5 unchanged functionality (except for the extended range of values)
In RTC
®
4 compatibility mode, the RTC
®
5 multiplies the specified scaling factor by 16 (the
permissible range of values is correspondingly reduced).
