2 Safety Instructions
see also enclosed safety instruction bookletno. 016000
WARNING
Potential loss of life due to electric shock!
Work on electrical equipment mayonly be carried out by qualified electrical
technicians.
WARNING
Serious injuries or even death possible!
Disconnect screwdriver from power supply before changing or mounting the
screwdriver tool (bit, socket) or accessory.
CAUTION
Screwdriver will heat-up in relation to its average load respectively
sequence of operation
If the selection of the type of screwdriver is incorrectly or its operation is not
appropriate for the application, the tool might overheatwhich could result in
injuries (burnings).
Use the screwdriver only as described in the operating instruction booklet.
CAUTION
Risk of crushing hands between holding bracket and work piece or
modification parts in confined spaces.
Make sure that any bracket used is correctly installed.
Keep hands away from holding fixture (if used). This applies especially
when unscrewing.
CAUTION
Rotating drive, rotating bit/socket or drive extension.
Injuries to fingers or even broken fingers.
When wearing gloves(e.g. rubber coated or metal reinforced) make sure
that they not become entangled.
Do not wear loose fitting gloves or gloves with cut or frayed fingers.

5
Never exceed the rated voltage and power.
Never hold the drive, screwdriver tool or drive extension with your hands.
If you cannot supportthe reaction torque of the machine independently then use a
torque support (e.g. linear stand, telescopic arm, holding fixture/holder-on, support
grip). It generally applies that: In any case use a torque support to absorb the reac-
tion torque above:for straight screwdrivers 4 Nm; for pistol grip screwdrivers 10 Nm
and for angle nutrunners 60 Nm.
If itis notpossible to use a torque support, use side handles for straight and pistol grip
screwdrivers. Side handles are recommended for straight screwdrivers at a torque set-
ting over 4 Nm and for pistol grip screwdrivers at torque settings over 10 Nm.
Use a finder/sleeve fitting where practicable.
When using sockets or adapters(e.g.magnet holder) make sure thatthey are in good
condition and suitable for use with this machine.
To prevent sockets breakage use only sockets (e.g. for impact or impulse screwdrivers)
which are suitable for use with this machine.
After turning off the tool, the screwdriver tool will continue to rotate (inertia).

3 Intended Use
This EC-Screwdriver Spindle is part of the EC-Screwdriving System, which is only designed
for screw-assembly in an industrial environment.
The MINIMAT-EC-Screwdriver Spindle of the series 320E… is designed for the stationary
use in:
Construction Slide Units
Multi-Spindle Screwdriving Stations
Cartesian Screwdriving Robots
Gantry Screwdriving Cells
DEPRAG EC-Screwdriver Spindles allow free programming of the screw tightening process.
Within the power range of the selected spindle,
the torque value
the speed
the stand-by and
the direction of rotation
can be adjusted individually to the assembly requirement.
The EC-Screwdriver Spindle is insulated to protect against an electrical power surge.
Start-up and continuous operation of the EC-Screwdriver Spindle are only
allowed in conjunction with a DEPRAG sequence controller (e.g. AST6,
ASTi6, AST10 or AST11).

5 General
The EC-Screwdriver Spindle 320E22-00xx0 is part of the EC-Screwdriving System.
The essential characteristics of this screwdriver series are:
brush-less EC-Drive with commutator over encoder
torque- and angle-controlling
The EC-Screwdriving System is designed for the use in an industrial environment for a
maximum torque of 1.2 or 2.0 Nm (depending on the type of screwdriver Technical
Data).
The EC-Screwdriving System mainly consists of two components:
the EC-Screwdriver Spindle of the series 320E22-00xx0.
the sequence controller AST10-1 / AST11-1 with integrated amplifier or sequence con-
troller AST(i)6
For more equipment Optional Equipment and Operating Instructions “Sequence Con-
troller AST10/AST11” or “Sequence Controller AST(i)6”
IMPORTANT
The operation of the screwdriver spindle requires a programmable se-
quence controller (AST10-1, AST11-1 or AST(i)6) with integrated amplifier
and a motor cable.
The sequence controller offers standard screwdriving programs for tightening screws to
a specific torque value respectively loosening at a specific angle value. Their parameters
are adjustable directly via the controller’s keyboard.
Special screwdriving sequences are easy to create: standard assembly steps, already
stored in the controller, can be selected and comfortably built up to form a complete as-
sembly process. This happens via the integrated web server’s PC operator board.
No special PC software is required – only a normal web browser (such as MS explorer)
and an Ethernet port.
Additional software modules for documentation and screw join analysis (data logging,
graphics, etc.) are available as optional equipment.
Also optionally available is an update service for the sequence controller which provides
continuous update of the controller’s function and control software.
The controller’s integrated display and operating unit indicates the operating mode and
assembly status. It also allows a direct change of parameters (such as speed, torque and
angle values etc.) within the assembly process and without the need of a PC connection.
In automatic mode, the sequence controller communicates with the system’s PLC.
Screwdriving programs can be selected and started. After completion of the assembly
process, the sequence controller will report the status of the result to the PLC.
An Ethernet port allows the network of more screwdriver spindles (i.e. multi spindle sys-
tems) with centralized process monitoring (graphics, statistics, individual data sets, etc.).

6 Assembly Instructions
WARNING
Potential loss of life due to electric shock!
Before working on the tool (e.g. assembly, installation and maintenance)
disconnect the electric equipment from power supply (switch off main switch
and pull out main plug).
6.1. Installation Instructions
When installing the EC-Screwdriver Spindle the following points have to be observed:
Install the EC-Screwdriver Spindle according to the Dimension Sheet.
The EC-Screwdriver Spindle may be installed in any orientation.
Use only mounting brackets having a sufficient size (Dimension Sheet).
Use only the mounting elements delivered to mount the EC-Screwdriver Spindle.
Level the EC-Screwdriver Spindle and the screwdriving position so that there are no or
only low radial forces (e.g. by dead load).
Support plates are not included in delivery of the EC-Screwdriver Spindle.
Make sure to choose a suitable material (e.g. steel with tensile strength
Rm 370 N/m²) for support plates.
Make sure not to exceed the max. driver stroke (Dimension Sheet) dur-
ing screwdriving.
