Operating principle: Absolute Encoder Emulation

SSI Format
The following illustration shows the format for SSI data transmission.
Fig. 8-33: SSI Format as Pulse Diagram
Note: The Power Failure Bit is not evaluated in the drive!
Emulated position reference
Emulation of the signals for "Position of the motor encoder," "Position of
the optional encoder" and "Position command value" is based on the
"feed constant" and "gear" parameters.
The values produced by the emulator are load-dependent.
Resolution with Absolute Encoder Emulation
The data output format for the emulated SSI position is stipulated in
parameter C015, Encoder emulation resolution.
• 4 .. 24 bit / mm
The output direction depends on parameter C000, Working polarity.
Homing with Absolute Encoder Emulation
Using parameter C010, Set absolute encoder, the absolute position
output by the absolute encoder emulator can be homed.
When the absolute encoder is set, the value from parameter C011,
Reference distance is processed.
