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

• SINUMERIK 802D sl
• SINUMERIK 840D sl³⁾

SINUMERIK 802D sl

Two ADI 4 interface modules can be connected to the SINUMERIK 802D sl, permitting analog control of all its axes.

Encoder connection

With SINUMERIK 802D sl (in accordance with the existing number of axes), the following configurations are available as standard for each ADI 4:

• 4 ? TTL signal inputs with S/R⁴⁾
  • 3 ? 2500, 1 ? 1024
  • 1 ? 9000, 1 ? 18000, 1 ? 1024, 1 ? 2500
    or
  • 3 ? 2048, 1 ? 1024
  • 1 ? 9000, 1 ? 18000, 1 ? 1024, 1 ? 2048

Other configurations can be implemented on request.

SINUMERIK 840D sl

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