4.6 Setting machine-specific parameters
4.6.1 General information
The functions of the sewing-drive control are determined by the program and
the parameter settings.
4.6.2 Autoselect
The control unit detects which machine series is connected by measuring the
Autoselect resistance in the machine. Autoselect selects control functions
and the pre-set parameter values.

ording to the corresponding parameter sheet (9800 331104 PB 53)
the correct machine class is to be set with parameter F-290.
Caution!
If the control unit fails to detect a valid Autoselect resistance (or any at all),
the drive only runs with the so-called emergency operating functions to
prevent machine damage.
