The ADI 4 interface module can be used with the following CNCs:

• SINUMERIK 840D sl

Several ADI 4 Analog Drive Interfaces can be connected to the SINUMERIK 840D sl, permitting analog control of all its axes. Mixed operation of digital drives and ADI 4 modules is possible; the axes can interpolate with one another.

Encoder connection:

• TTL incremental encoder with differential transfer:
  • Track A and inverted signal A
  • Track B and inverted signal B
  • Zero signal and inverted zero signal
  • Output frequency max. 1.5 MHz
  • Phase shift of track A to track B: 90° ± 30°
  • Power consumption max. 300 mA
• Absolute encoder with SSI signal:
  • True and inverted output signal
  • Shift clock as true and inverted signal
  • Transmission frequency max. 750 kbaud
  • Power consumption max. 300 mA
    Only multi-turn encoders are approved for this purpose.
• Linear encoder with distance-coded zero marks/reference marks
  • LS 476 C
  • LS 186 C with external pulse-shaper electronics EXE
• Encoder with sin/cos signals can be connected via external pulse-shaper electronics EXE.
