straight handle design and pistol-grip design
torque ranges between 0.06 - 4.0 Nm
The EC Screwdrivers allow free programming of the screw tightening process. Within the power range of the selected tool, the torque value, speed, stand-by and direction of rotation can be adjusted individually to the assembly requirement.
Outstanding features of hand-held EC-screwdrivers are their torque precision and the large range of control functions - perfect conditions for process security and control on highest level.
The brushless electric motors provide nearly maintenance-free operation. They are ideally suited for the tightening of screws due to their outstanding dynamics and an achievement of high peak torque values.
Integrated monitoring of torque and angle values allow the exact control of the screw tightening process, as well as the documentation of all important process parameters.
The operation of the screwdriver requires a programmable sequence controller (AST10) with integrated amplifier and a motor cable (available in different lengths).
The sequence controller offers standard screwdriving programs for tightening screws to a specific torque value respectively loosening to 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 assemly process.
This happens via the integrated web-server's PC operator board. Additional software modules for documentation and screw joint analysis (data logging, graphics, etc.) are available as optional accessories. Also optionally available is an update service for the AST10 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 (speed, torque and angle values, etc..) within the assembly process and without the need of a PC-connection.
The screwdriving sequence will be initiated by either push-to-start or trigger start, depending on the type of screwdriver. Selection resp. change of the screwdriving sequence can be done via a menu function. Applications with frequently changing screwdriving parameters can be controlled via a program selection box or a input/output communication of a PLC.
A higher level of process security is offered with the use of a position checking stand in conjunction with a PLC. The selection of screwdriving programs or the series of screw assemblies is possible in conjunction with the XY-coordinates of this stand.
