Normal set_fly_rot
List Command
Function activates Processing-on-the-fly correction for compensation of workpiece rotary
movement (based on angular position values transferred to the RTC
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);
Comments • For Processing-on-the-fly correction and determining the Resolution parameter, see
"Processing-on-the-fly (Optional)", page
• Before executing the command set_fly_rot, you should define the rotation center for
Processing-on-the-fly correction via
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
• For deactivating Processing-on-the-fly correction, see
• 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_ctrl
simulate_ext_start,
set_control_mode, bit#2).
