5.5.4 Objects for acceleration calculations
5.5.4.1 Object 608Dh: acceleration notation index (DS402)
Index 608Dh
Name acceleration notation index
Object code VAR
Data type INTEGER8
Category mandatory
Access rw
PDO mapping not possible
Value range INTEGER8
Default value 0
The "acceleration notation index" scales acceleration setpoints, which units are defined with
the"acceleration dimension index" as SI-units, in powers of ten.
Relationship between the Object-values and the parameter ACCUNIT:
Value of Object 608Dh ASCII parameter ACCUNIT Scaling
0 1,5 1
FAh 3 10
-6
FDh 4 10
-3
5.5.4.2 Object 608Eh: acceleration dimension index (DS402)
Index 608Eh
Name acceleration dimension index
Object code VAR
Data type UNSIGNED8
Category mandatory
Access rw
PDO mapping not possible
Value range UNSIGNED8
Default value AEh
The "acceleration dimension index" defines the SI-unit of the used acceleration setpoints. Rela-
tionship between the Object-values and the manufacturer-specific parameter ACCUNIT:
Value of Object 608Eh ASCII parameter ACCUNIT SI unit
AEh 1 rad/s²
55h 3, 4, 5 m/s
The parameter ACCUNIT can be stored in the drive. The values for Objects 608Dh and 608Eh are
initialized by this parameter. Only the described values for ACCUNIT are possible with the profile
DS 402.
