Position Input For Motion Control; Fast Mode; Additional Functions - Siemens SIMATIC S7-1500/ET 200МР Manual

2.2.4

Position input for Motion Control

You can use the technology module for position detection for the following axis technology
objects of S7-1500 Motion Control :
• TO_PositioningAxis
• TO_SynchronousAxis
• TO_ExternalEncoder
In this operating mode, you can use the measuring input technology object
(TO_MeasuringInput) to execute a measuring input function with hardware digital input DI1.
Additional information
You can find a detailed description of the use of Motion Control and its configuration in the
following:
• Function manual S7-1500 Motion Control available for download on the Internet

2.2.5

Fast Mode

You can use the technology module in Fast Mode for very fast input of the counter value in
case of compressed functionality. A reduced feedback interface but no control interface is
available in Fast Mode. This allows you to use a shorter send clock for the CPU.
2.2.6

Additional functions

Synchronization
You can configure the edge of an external reference signal that loads the counter with the
specified start value. The following external signals can trigger a synchronization:
• Rising or falling edge of a digital input
• Rising edge of signal N at the encoder input
• Rising edge of signal N at the encoder input depending on the level of the assigned digital
input
The "Frequency of synchronization" parameter specifies whether the function is executed at
each configured edge or only once after each enable.
Hysteresis
You can specify a hysteresis for the comparison values within which a digital output will be
prevented from switching again.
