1.3.2.4.1 Index Storing Function

The index storing function is provided so that the encoder counts can be latched allowing the user to determine
the position of the encoder relative to an absolute position.
The function is available only with Field Oriented mode.

Parameter to select the source Index storing command.
For example it is possible to switch the factory setting, Int IS ctrl, to control from
another source, for example, from an SBI word or DGFC word; see table below
for the corresponding values for control.

enables the capturing of the encoder count as de
scribed by the setting of the control word. The control
word is the value of Int IS ctrl or the word selected
by IS ctrl src (see below for details).
with this setting, constantly reads all the generated
pulses on the standard encoder input
(ex.: if encoder = 1024 pulses, 1 turn shaft = 1024 pulses).
