See AB221A/AB321A.
Additional features:

• Expanded to 24 inputs and 21 outputs
• 2 programmable analog outputs (0-10V)

Drive for all sewing applications performed in synchronization with the main sewing machine drive.

Complex, preprogrammed operational modes such as elastic tape feed (gathering / flat sewing), cuff and heel tape, puller feed, roller feed for sewing pre-closed elastic waistband, etc., are easily selectable using parameters.

Actuators can be operated stand-alone (without sewing drive).
Up to 99 programs can be selected on the control panel.
5 outputs and 10 inputs are available for the control of feeding and trimming operations.

The stepping motor control unit communicates with the all Efka Compact control units.
