Class-838 specific adjustments to the parameters of the Efka drive

The programming and setting of parameters is used to specify the
function of the sewing drive controller.
All parameter values for the corresponding sub-classes are already
assigned when the complete sewing machine is delivered. Some
pre-set values for the controller (e.g., maximum rotational speed) may
also be changed. When replacing the controller, these
machine-specific parameters must be re-specified on the new
controller.
Drive parameters are set in two steps. In the first step, the function
"Auto-select" is used to set the machine class parameters. In the
second step, some pre-set parameters are changed in order to set the
machine-specific parameters in the sub-class.
The sewing drive controller detects which sewing machine class is
connected by measuring the auto-select resistance from the machine.
Auto-select is used to select control function and the pre-set values of
the parameters.
Caution! If the controller detects an invalid or absent auto-select
resistance, then the sewing drive will only operated with
emergency-run functions. This serves to protect the machine from
damage.
Caution!
Be very careful when adjusting the parameter values. The machine can
be damaged when settings are made improperly.
Note:
All parameter values can be reset to their default (pre-set) values by
using the Master Reset function (refer to section 6.3).
A description of parameter settings can be found at www.efka.net or in
the Efka operating instruction booklet provided by the drive
manufacturer.
