Contains the feedback encoder revolution count.
Contains the reference encoder position.
The top 16-bits are scaled to 65536 counts per rev regardless of the type of feedback
device or scaling configured in the drive. The lower 16-bits give the fine position as
available from the feedback device scaled to 65536. For standard encoders this will
typically be zero, but for higher precision devices such as SinCos encoders, this extra
precision will be available.
Marker pulses, etc. have no influence on this parameter.
Contains the reference encoder revolution count.
Provides a definitive method of identifying the mode the drive is in. It is recommended
that this parameter is used instead of Pr
11.31
or Pr
00.48
since those parameters
indicate the requested, not the actual mode.
The values are defined as follows.
In order to programmatically change the drive mode, use the MODEXFER or
CMODEXFER function blocks.
