5.5.3 Objects for velocity calculations
5.5.3.1 Object 608Bh: velocity notation index (DS402)
Index 608Bh
Name velocity notation index
Object code VAR
Data type INTEGER8
Category mandatory
Access rw
PDO mapping not possible
Value range INTEGER8
Default value 0
The "velocity notation index" scales velocity setpoints, which units are defined with the "velocity
dimension index" as SI-units, in powers of ten.
Relationship between the Object-values and the parameter VUNIT:
Value of Object 608Bh ASCII parameter VUNIT Scaling
0 0 1
0 1 1
0 5 1
0 6 1
FDh 7 10-3
FDh 8 10-3
5.5.3.2 Object 608Ch: velocity dimension index (DS402)
Index 608Ch
Name velocity dimension index
Object code VAR
Data type UNSIGNED8
Category mandatory
Access rw
PDO mapping not possible
Value range UNSIGNED8
Default value 0
The "velocity dimension index" defines the SI-unit of the used velocity setpoints. Relationship
between the Object-values and the manufacturer-specific parameter VUNIT:
Value of Object 608Ch ASCII parameter VUNIT SI unit
A6h 0 m/s
A4h 1 turn/min
A6h 5 m/s
A7h 6 m/min
A6h 7 m/s
A7h 8 m/min
The parameter VUNIT can be stored in the drive. The values for Objects 608Bh and 608Ch are ini-
tialized by this parameter. Only the described values for VUNIT are possible with the profile
DS402.
