SSI baud rate 100 . . .250 kBaud
Resolution absolute position SSI 30 bits
Max. cable lengths
●
For TTL incremental encoder
● For HTL incremental encoder
● For SSI absolute encoder
● 100 m (bipolar signals only)
2)
● 100 m (for unipolar signals)
● 300 m (for bipolar signals)
1) 2)
● 100 m
1)
As of a cable length of 200 m, use a power supply cable with a cable cross-section
≥ 0.75 mm²!
2)
Signal cables twisted in pairs and shielded.
NOTICE
Destruction of the encoder electronics
Operation of a 5 V encoder on the 24 V encoder supply may result in the destruction of its
electronic components!
Make sure that you can operate the connected encoder on a 24 V power supply (e.g. HTL
encoder).
This setting can be set in the expert list of the drive in parameter p0400 and in the
following parameters.
