Park_Return - Scanlab RTC6 PCIe Board Installation And Operation Manual

Variable

park_return

List Command
Function Moves the output point (of the laser focus) away from a park position along a 2D vector
at jump speed to the specified position (absolute coordinate values) within the 2D
Field.
Restriction If the Option Processing-on-the-fly
Jump Command. If the laser focus is not currently in a park position, then park_return is
a short list command with no effect (see below).

Comments • park_return is intended for encoder-based
Processing-on-the-fly applications where the laser focus should leave a safe parking

park_position.
• If a
off by a prior park_position( Mode = 0 ) call, then park_return switches the same
Processing-on-the-fly mode back on. Other Processing-on-the-fly modes are not
switched back on.
• If the park position has been attained by park_position, then park_return( Mode = 0 )
returns the galvanometer scanners to the most recent valid position before
park_position
position specified with the command. When calculating the new position, the RTC6
takes the current Processing-on-the-fly correction into account. But if clipping to the
boundaries of the virtual
motion during a list interruption by wait_for_encoder), then the Processing-on-the-fly
mode is not reactivated (see also
executes without Processing-on-the-fly correction.
