Normal
List Command set_fly_rot
Function activates Processing-on-the-fly correction for compensation of workpiece rotary
movement (based on angular position values transferred to the RTC
®
5 via encoder counter
Encoder0) and sets the corresponding
Resolution
parameter. Encoder counter Encoder0
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_rot( Resolution )
Parameter
Resolution
number of steps per revolution (as a 64-bit IEEE floating point value);
allowed range: |
Resolution
| > 100.0
Comments • For Processing-on-the-fly correction and determining the
Resolution
parameter, see
"Processing-on-the-fly (Optional)", page 177 .
• Before executing the command set_fly_rot , you should define the rotation center for
Processing-on-the-fly correction via set_rot_center or set_rot_center_list . Otherwise,
the default value (0|0) will be applied.
• If unallowed parameter values are supplied (e.g. for
Resolution
= 0), then set_fly_rot
will not activate a Processing-on-the-fly correction or will deactivate a Processing-on-
the-fly correction previously activated via
set_fly_rot (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_rot “
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
Encoder0 should reset immediately via set_fly_rot 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).
