● should be configured on the respective device. (I/O channel is configured as measuring
input (MI)).
● can be assigned on the SIMOTION-CPU to an axis TO or external encoder TO.
● Configuration by way of symbolic assignment is possible.
If current controller clock cycles <> 125 μs are used, the parameter calculations of the drive
must be taken over into the PG and the Fast IO configuration must be recreated when using
global measuring inputs (for further information, see chapter entitled Current controller clock
cycles <> 125 μs / use of output cams and measuring inputs in the TM15 / TM17 High Feature
Terminal Modules Commissioning Manual)
Time stamp functionality
With global measuring inputs, a time value (time stamp) is stored with each measurement. In
this way, the exact axis position can still be determined even with different propagation delays
between the time of the measurement to the evaluation.
5.2.2
Hardware for measuring inputs
Description
Global measuring inputs are only supported by certain hardware (measuring inputs) (see table
below).
Hardware for local and global measuring inputs
The following table provides an overview of which hardware supports local and which hardware
supports global measuring inputs.
