Encoder Simulation Status (1x.086) shows the status of the encoder simulation output.
0: None
The encoder simulation output is not enabled or is not available.
1: Full
Full encoder simulation with marker output is available.
2: No Marker
Encoder simulation without marker output is available.

The update rate of the encoder simulation system is nominally 250 µs, i.e. the default value of the
Encoder Simulation Sample Period (1x.087). However, if the update rate of the source parameter is
different, the encoder simulation output will consist of bursts of pulses at the update rate of the
parameter. To prevent this and to give a smooth output, the update rate can be adjusted with the
Encoder Simulation Sample Period (1x.087). The Encoder Simulation Sample Period (1x.087) has
no effect if the hardware mode is selected, i.e. the Encoder Simulation Mode (1x.088) = 0.

The Encoder Simulation Mode (1x.088) defines the encoder simulation output as incremental
signals (AB, FD or FR) derived directly via hardware, incremental signals generated via software or
SSI data generated via software.
0: Hardware
The encoder simulation output can be derived directly in hardware from the P1 position feedback
interface on the drive, or the P1 position feedback interface on the module. The output is derived
from the input with negligible delay. The ratio between the input at the P1 interface and the output,
is either unity or a limited number of binary divider ratios (see Encoder Simulation Hardware Divider
