9.2 Correction of the Set Values (Parameters)
For adaption of the drive to the individual machine class it
is essential that several parameters be checked and, if
necessary, the values set at delivery corrected.
Here the parameter no. of the parameter to be corrected
must be selected and the value shown in the display
increased (+) or reduced(-).
The following parameter no.s are to be given particular
attention:
a) Maximum Rpm
F111 with Efka modular
607 with Quick digital
No greater number of stitches/min. may be set than is
allowed under Section 1.2 of the machine class to be
powered. The set value is the first informtion shown
in the display after the main switch is turned on.
With 3-phase sewing drives the max. number of
stitches/min. (pedal stepped fully down) must be
chosen by selecting the motor belt pulley. See
Section 4.4.
The max. number of stitches/min. shown in the control
panel must be set accordingly to the value of the
motor belt pulley in the above parameter.
A reduction in the number of stitches below max. is then
possible at the control panel.
b) Reference position (0-Position)
F170 with Efka modular
700 with Quick digital
Setting before inserting the 10-pole machine plug into the
motor control is essential. The reference position is
reached when the handwheel is turned in the
direction of operation and arrested in position D.
In this position the needle position slot F and the needle
position slot C are simultaniously correctly set for
most applications. Corrections of these needle
positions are possible in the following parameters:
with Efka modular
F-171. 1- Needle position slot F
F-171. 2- Needle position slot C
with Quick digital
702 - Needle position slot F
703 - Needle position slot C
(See Section 11.)
