Ctrl Command control_command
Comments General comments:
• The control_command command can only be used in conjunction with an iDRIVE
system (intelliSCAN
with XY2-100 interface and XY2-100 converter. Conventional scan systems (without iDRIVE
technology) will ignore the command.
• With invalid values of Head and/or Axis, the command is not executed
code: RTC5_PARAM_ERROR). This also applies for Head = 2 if the "second scan head control"
option has not been enabled.
• Command code Data is transmitted to the scan system instead of the usual position data for
Head and Axis. Therefore, the corresponding galvanometer scanner microstep is omitted, if the
command is called during execution of a list.
• Some parameters of control_command are not usable with older firmware versions of "intelli"
scan systems. These parameters are specifically noted. All other parameters are usable with any
firmware version.
• Under some circumstances, control_command might be unavailable at the primary scan head
connector if speed-dependent laser control has been activated via
(Mode = 2).

short (serial transmission-related) delay before transmission of the first data. After switching
data sources, therefore, a delay time of up to 60 µs can occur before reading the data. As of
DLL version 520, control_command always automatically inserts a waiting time of 60 µs after
the data source is switched (so that the previously mentioned commands will now always
return correct values).

returned from the scan system (also see get_value). After a reset or power-up of the scan
system, always the XY2-100 status word is returned.
