machine control
Electric control:
- SIEMENS S7 - CPU 317-PN / DP (with Profibus and Ethernet)
- Control programmed in STEP 7 with GRAPH 7 sequencers
- Hydraulic system: Fabr. REXROTH
- Main pump: make PARKER
- Spindle drive: make LENZE incl. Inverter (147 kW)

Basic equipment:
- Active TFT color display 12 inches
- Membrane keyboard with full character set
- Menu selection
- Display during monitoring. During the welding process, the actual values are both
  can be displayed digitally as well as in analogue graphs. This device allows a visual
  Control of the welding process of the machine and the monitoring device.
- Machine and monitoring values for 128 programs (additional programs on diskette
- Interface for printers. With the printer, all set machine parameters,
  Monitoring limits and for each weld all actual values are logged.
- All welds are identified by serial numbers. In addition, the
  Counter readings for good parts, rejects and aborted welding attempts, too short or
  printed too long components.
- single-cell expression and / or curve expression
- Storage of the actual values of the last 16 parts
- Floppy disk drive for archiving 128 welding programs per floppy disk
- Printout of the program overview of all 128 programs
- Printout of the message buffer (last 200 messages)

Following tolerance limits are freely adjustable:
- Max. and min. common relative output length, the so-called initial position of the two
  Components in 0.01 mm
- Max. and min. Spindle speed During the friction phase in min-1
- Max. and min. Frictional pressure during the friction phase in bar
- Max. and min. Friction path (friction shortening) at the end of the friction phase in 0.01 mm

- Max. and min. Time of the friction phase in 0.001 sec
- Max. and min. Compression pressure during the compression phase in bar
- Max. and min. Total shortening after welding in 0,01 mm
- Brake phase monitoring (time and average pressure)
- if necessary, max. and min. Angular position after the positioned friction welding
- Max. and min. common relative final length, the so-called end position in 0.01 mm
