Connectable measuring systems
Incremental encoder (TTL)
● Differential transmission with RS 422 and operating voltage 5 V or 24 V:
– Track A as true and inverted signal (U
a1
, /U
a1
)
– Track B as true and inverted signal (U
a2
, /U
a2
)
– Zero signal N as true and inverted signal (U
a0
, /U
a0
)
● Maximum output frequency: 1.5 MHz
● Phase shift of Track A to Track B: 90° ± 30°
● Current consumption: Max. 300 mA
● Encoders with distance-coded zero marks/reference marks are not generally enabled.
Absolute encoder (SSI)
● Transmission method: Synchronous serial interface (SSI) according to RS 485 with 5 V
differential signal transmission (RS 422 standard)
– Output signal: Data as true and inverted signal
– Input signal: Shift clock as true and inverted signal
● Data transmission format: "Pine tree"
● Resolution: maximum of 25 bits
● Maximum transmission rate: 1 Mbit/s
● Current consumption: Max. 300 mA
The following SSI encoders are supported:
● All SSI encoders in the pine tree format whose MsgLength is equal to the number of
"significant data bits":
– 25-bit with 12-bit multiturn and 13-bit single-turn information (setting of the
MsgLength 25)
– 21-bit with 8-bit multiturn and 13-bit single-turn information (setting of the
MsgLength 21)
– 21-bit with 9-bit multiturn and 12-bit single-turn information (setting of the
MsgLength 21)
– 13-bit with 13-bit single-turn information (setting of the MsgLength 13)
● SSI encoder in the pine tree format with the following data:
– 25-bit with 12-bit multiturn and 12-bit single-turn (setting of the MsgLength 24)
– 21-bit with 8-bit multiturn and 12-bit single-turn information (setting of the
MsgLength 20)
– 13-bit with 12-bit single-turn information (setting of the MsgLength 12)
– This applies as long as the encoder permits that not all available data is read!
● All right-justified encoders that satisfy the first condition indicated above.
