Position input for Motion Control

You can use the technology module for position input with S7-1500 Motion Control .
To do this, select "Position input for Motion Control" in the device configuration of the
technology module in STEP 7 (TIA Portal).
When using an incremental encoder or pulse encoder, the position input is based on the
counting function of the technology module. With an SSI absolute encoder, the absolute
value is read in via a synchronous, serial interface and prepared according to the parameter
assignment to be made available for S7-1500 Motion Control.
Additional information
A detailed description of the use of Motion Control and its configuration is available in the
function manual S7-1500 Motion Control as a download from the Internet
(http://support.automation.siemens.com/WW/view/en/59381279).

Additional functions

Hardware interrupts
The technology module can trigger a hardware interrupt in the CPU, for example, if a
compare event occurs, in the event of a zero crossing and/or a change of count direction
(direction reversal). You can specify which events (Page 49) are to trigger a hardware
interrupt during operation.
Diagnostic interrupt
The technology module can trigger a diagnostic interrupt in the event of a missing supply
voltage or an error at the digital outputs, for example. Select the diagnostic interrupts
(Page 47) in the device configuration freely.
Monitoring of encoder signals
The technology module monitors signals of an encoder for wire breaks, short-circuits and
offset voltages. In the case of an SSI absolute value encoder, the technology module also
monitors SSI frames for errors.
If you enable the diagnostic interrupts, the technology module triggers a diagnostic interrupt
in the event of a corresponding error.
Input filter
To suppress interference, you can configure an input filter for the RS422/TTL encoder inputs
and for the digital inputs.
