Update rate: Background read
The simulated encoder output (incremental), Ab, Ab.L, Fd, Fd.L can be scaled using the above parameter.
An encoder simulation output can be generated from any parameter as a source as defined by Pr x.24 (00.00 disables encoder simulation). Although
any parameter can be used, the source parameter is assumed to be a 16 bit position value in the form of a roll-over counter. Therefore only
parameters with a range of -32768 to 32767 or 0 to 65535 are normally used. The marker is simulated when the source rolls over or under.
The sources update rate should be considered when setting up a simulated encoder output, for example with Pr x.05 as the source this has an
update rate of 250μs (shortcut in software) with Pr x.30 this has an update rate of 4ms (averaging is applied for the simulated encoder output in this
example to prevent "stepping effects" being seen on the simulated encoder output).
When the Solutions Module is connected to a high precision encoder (i.e. SinCos) and the source has been selected as the internal position (Pr x.05),
the resolution can be increase to a 24 bit position value by setting Pr x.27 to a one.

Encoder simulation mode

RW Txt
0 to 7
Update rate: Background read
Pr x.28 defines the output mode for simulated encoder output as follows.
Pr x.28 String
0 Ab Quadrature
1 Fd Frequency and direction
2 SSI.Gray SSI output (Gray code)
3 SSI.Bin SSI output (Binary format)
4 Ab.L Quadrature with marker LOCK
5 Fd.L Frequency and direction with marker LOCK
6 H.drv Drive ABZ input signals routed through Hardware
7 H.int Solutions Module ABZ input signals routed through Hardware
NOTE
Modes 6 and 7 are only available with the drive software versions 01.07.00 onwards, and issue 4 SM-Universal Encoder Plus.
NOTE
If the source is not the feedback device, the simulator waits until all feedback devices are initialized before the starting to output. The wait for
initialisation does not occur if the drive software version is less than V01.08.00.
NOTE
Also refer to the SM-Universal Encoder Plus User Guide for further detailed information.
