4.13.2 Sewing with machines using the Efka DC1550/
DA321G positioning drive
The DA321G control unit contains all required operational inter-
faces for switching functions and setting parameters.
It is possible to operate without an operating panel, but the seam
programming can no longer be carried out.
The V810 and V820 operating panels can also be connected to
the control unit. They are deliverable as accessories.
Seam programming can be performed with the V820 operating
panel.
The EFKA DC1550 – DA321G Operating Manual contains a more
detailed description of the control unit (also refer to
www.efka.net).
