Cyclic Data Access
NOTE
Received Dout data words are processed by the drive in a fixed sequence starting with the Word pointed
to by parameter P440 and then P441 … P445. That might lead to overriding the commands/setpoints
mapped earlier in the sequence (ex. in P440) by data mapped later in the sequence (ex. in P445).
Example:
Dout size = 3 words
P440 set to 3 – C135 Lenze Control Word
P441 set to 2 – Network Command Frequency
P442 set to 1 – SMV Control Word
In this case if the C135 Control Word bits are set to STOP and the SMV Control Word bits are set to RUN,
the drive will START! (The SMV Control Word pointed to by P442 is processed last)
5.2.2 Data IN (Din) Channels
P460 to P465 - Din Mapping Channels
Default: various
Range: 0 - 550
Access: RW
Type: Integer
The SMV PROFIBUS-DP module has 6 cyclic IN channels each of which utilises 1 WORD of data.
In addition to the mappable functions listed in Table 8, any drive parameter can be used as a source
parameter. Simply enter the required parameter number into the appropriate mapping parameter.
Last mapping channel not equal to 0 sets the size of Din data portion

Din Channel 2 mapping

NOTE
Refer to paragraph 5.4 for details on Control and Status Words.
When mapping parameters that have decimal places, scaled integer values are used. For example: to
read P508 the Actual Motor Current value, a value of 10.8A would be transmitted as 108.
