10 Description of the object dictionary
Description
The subindices have the following function:
•
00
h
: Value = "n", where "n" is the number of existing feedbacks.
•
n
h
: Subindex "n" contains the number of revolutions of the output shaft for the corresponding
feedback.
Subindex 01
h
always corresponds to the first (and always existing) sensorless feedback.
The feed constant of feedback "n" is calculated as follows:
Feed Constant = Feed (60E9
h
:n
h
) / Driving Shaft Revolutions (60EE
h
:n
h
)

= "1" is set.
Bit 1
Bit 0
Definition
0
0
Position movements are executed relative to the previous (internal
absolute) target position (each relative to 0 if there is no previous target
position)
0
1
Position movements are executed relative to the preset value (or output)
of the ramp generator.
1
0
Position movements are performed relative to the current position (object
6064
).
