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).
