Command General program step to create the screwdriving sequence (e.g.
setting the output).
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.
