Microstepping - Scanlab RTC6 PCIe Board Installation And Operation Manual

7.1.2 Microstepping

The RTC6 PCIe Board splits up each
• Jump Command,
• [*]mark[*] Command and
• "Arc" Command
into so-called
• Microsteps
(not: Microvectors, see
"micro_vector[*] Commands", page
The split-up of the x component of a vector into
Microsteps is shown in Figure

The x component of a vector is split-up into Microsteps.
The y component is split-up in the same way.
All Microsteps are transferred to the scan head with
a constant output interval (t) of 10 µs and cannot be
changed.
The following applies:

Notes
• Custom curves can be implemented by using
micro_vector[*] Commands, see
"micro_vector[*] Commands", page
• Only iDRIVE scan systems
with an appropriate tuning can execute jumps
also in Jump Mode, see
"Jump Mode", page 217.
