5.5.5 The SSI-Interface (only ZX09A, ZX09D and ZX09E)
The ZX09A controller has up to two SSI interfaces. These are identified on the unit
by the SSI and RS-485 terminals. An absolute encoder can be connected via this
interface. Both "Single-Turn" and "Multi-Turn" versions are possible as well as the
data formats "binary code" and "gray code". Both the SSI interface and the RS-485
interface can be configured as SSI interface via the predefined function blocks
"enc_ssi_mt" or "enc_ssi_st" in EX_PRESS 5.
Note:
The SSI interface is assigned in "EX_PRESS 5" (Art. No. 589092) via the
corresponding function block (see user manual for the program
development system EX_PRESS 5, Chapter 4.4 "Function blocks in
devices.lib" )
