Function description during bending of flat sheet metal
Advice
Bending of wavy sheet
metal
The beams of the AKAS® must be located at a certain distance to the bending punch.
(See chapter 5.2 Overrun Traverse Measurement and
chapter 5.8 Adjustment of the distance between the AKAS® and the bending punch.
Caution! Use only tools with equal overall height within one fixing.
Closing movement with interrupted protective field
The AKAS® system offers the possibility to execute a closing movement under monitored slow speed even when
the protective field is interrupted by a wavy sheet metal.
After the interruption of the protecfive field and the release and reactivation of the foot pedal, the AKAS will
deactivate the SGA output when the protective field is interrupted. By this, only slow speed will be enabled by the
machine control (NC).
AKAS® provides a reaction time of about 200ms for the machine control and then activated the safety switching
outputs for the closing movement (OSSDs). The OSSDs remain activated as long as the AKAS® receives a
slow speed message to SGS and SGO:
by AKAS®...F within the next 70 ms + the selected enhanced tolerance (see page 35/36)
by AKAS®...M within the next 170 ms (A tolerance enhancement is possible only with the AKAS®...F systems).
By twice pressing the foot pedal can also use this function to perform a stroke, when the protective field
of the AKAS ® is interrupted in the OT.
