FLEXIBLE ASSEMBLY SYSTEM FAS200
User Manual for FAS200 - 81 -
Rotary movement and movement regulation is effected by step motor (servo/
direct current), with a phase A/B incremental encoder to provide instantaneous
reading of motor rotation. Control is via driver
which set up a closed loop force-position-speed
regulation system. This involves encoder
feedback and the force-position-speed setpoints
required at any particular moment supplied by the
PLC governing the module.

• Vision system:
As mentioned, the body is rotated to the first of two inspection positions, and a
vision camera confirms the colour and presence of the shaft, the height, the
colour and the presence of the cover and the presence of two of the four
screws. The system is used with monitoring purposes, based on an open-loop
concept. Then it rotates to the second inspection position and the vision system
confirms the presence of the remaining two screws. If the inspection results are
good, the turning mechanism is returned to the pallet retained at the transfer.
The vision system consists in a vision sensor with
integrated camera and controller. It can be used to
easily achieve simple inspections and
measurements.
