6.10.4 Checking positioning
Position 1
–
Turn on the main switch
–
Briefly push the pedal forward, then release it. The needle moves
to position 1.
–
Check the needle position.
Position 2
–
Push the pedal forward, then push it back and hold it there until the
machine halts. The needle moves to position 2.
–
Check the needle position.
If either or both of the needle positions do not coincide with the
definition in section 6.10.1, the setting must be corrected as described
in section 6.10.2 or 6.10.3.
6.11 Setting machine-specific parameters
6.11.1 General
The functions of the sewing-drive control are determined by the
program and the parameter settings.
All parameter values for the relevant machine class and subclass are
pre-set by EFKA prior to delivery of the sewing drives. For each class
and subclass some parameters at technician and manufacturer level
must be changed so that the control is perfectly coordinated with the
machine. The parameters concerned are listed in the table below and
in the parameter sheet (in the accessory pack).
6.11.2 Autoselect
The control “recognises” which machine series is connected by
measuring the Autoselect resistance in the machine. Autoselect
selects control functions and the pre-set parameter values. If the
control fails to recognise a valid Autoselect resistance (or any at all),
the drive runs only with the so-called emergency operating functions to
prevent machine damage.
See the “EFKA DA82GA” or “EFKA 6F82FA” operating manual.
