6.2 Structure of the mapping parameter, 1A00h-1A02h
Sub-index 0 contains the number of valid object entries. The value of 0 disables the
mapping function.
The following entries contain the information of the mapped application objects. The
object describes the content of the PDO by their index, sub-index and length in bit:
31
16 15
8 7
0
Index
Sub-index
Length in bit
MSB
LSB
6.2.1 Procedure for re-mapping
Destroy TPDO by setting bit
“valid” to 1 of sub-index 1 of the according
communication parameter 1800h-1802h.
Disable mapping by setting sub-index 0 to 0 in the according mapping parameter
1A00h-1A02h.
Modify mapping by changing the values of the corresponding mapping parameter
1A00h-1A02h (from sub-index 1).
Enable mapping by setting sub-index 0 to the number of mapped objects in the
corresponding mapping parameter 1A00h-1A02h.
Create TPDO by setting bit “valid” to 0 of sub-index 1 of the according
communication parameter 1800h-1802h. The desired COB-
ID and the bit “valid“
must be set together with one write command!
Save mapping configuration by means of
“Object 1010h: Store parameters”.
Provided mapping objects:
-
– Position value, single-sensor-operation, see page 168
-
– Position values for multi-sensor devices, see page 171
-
– Speed values, see page 172
