Resolution absolute position SSI 30 bit
Max. cable lengths
• For TTL incremental encoder
• For HTL incremental encoder
• For SSI absolute encoder
• 100 m (bipolar signals only)
1), 3)
• 100 m (for unipolar signals)
• 300 m (for bipolar signals)
1), 2)
• 100 m (depending on the baud rate)
4)
1)
Signal lines twisted in pairs and shielded.
Because the transmission technology is more robust, the bipolar connection should always be used.
The unipolar connection should only be used if the encoder type does not output push-pull signals.
2)
As of a cable length of 200 m, use a power supply cable with a cable cross-section ≥ 0.75 mm²!
3)
100 m with remote sense
4)
For the cable length, see the diagram "Maximum cable lengths depending on the SSI baud rate for SSI
encoders"

Note
The CUA32 control unit adapter also provides an encoder interface for an HTL, TTL or SSI encoder.
The technical data of the CUA32 adapter module can be found in the SINAMICS S120 AC Drive
Manual.
