Term Description
Clearance for start If the clearance for start is activated then the screwdriver will
only start if there are 24V at the clearance to start input. Oth-
erwise the controller is not ready to screw.
Command General program step to create the screwdriving sequence
(e.g. setting the output).
DAST Software packages DAST is used to supervise the operation
and visualisation of the screwdriver sequence controller (AST
series) through the system control.
EC screwdriver The screwdriver has a brushless electronic drive (EC motor,
abbreviation for electronic commutate).
EC servo screwdriver The screwdriver has a brushless electronic drive (EC motor,
abbreviation for electronic commutate) and has an integrated,
sensor controlled torque and angle of rotation measurement.
Encoder visual sensor to detect the current position of a motor shaft or
a drive unit
