Software mode - Absolute SSI data
In software mode, the encoder simulation output is derived via software from the selected source
with a minimum delay of 250 µs which may be extended with Encoder Simulation Sample Period
(1x.087). In SSI output mode drive will simulate an SSI encoder, where the number of bits and the
format of the position message can be adjusted.

Set to the parameter number of the position source Pr 1x.029 to use
the P1 position interface on the drive as the source.
Pr 2x.029 to use the P2 position interface on the drive as the source.
This parameter can be set to any other valid position reference
generated by the drive or an option module.
Set to a value of Ratio (2)
Set these two parameters to give the required output ratio.
AB/Gray (0) for a AB quadrature output signals
FD/Binary (1) for Frequency and Direction output signals
FR/Binary (2) for Forward and Reverse output signals
Set to the parameter number of the position source.
Pr 1x.029 to use the P1 position interface on the drive as the source.
Pr 2x.029 to use the P2 position interface on the drive as the source.
This parameter can be set to any other valid position reference
generated by the drive or an option module.
Set to a value of SSI (3)
Set to the number of bits representing the number of turns in the
position message.
Set to the number bits in the whole position message.
AB/Gray (0) for position data in Gray code format
FD/Binary (1) or FR/Binary (2) for position data in binary format.
