The object 0x2000 is defined as a manufacturer object, via which the parameterization

of the frequency inverter can be done.

With the help of the object, an "internal" communication channel, via which all the

parameters and values are accessible, is implemented. In this way, creation of more

than 600 objects, which would be necessary to map all the product-internal

parameters under the CANopen communication protocol, is no longer necessary.

The sub indices in question are to be used for writing and reading of

parameters/values, depending on the type int/uint, long and string. The data type of

the required parameter can be seen from the parameter list of the frequency inverter.

The standards with regard to error reports under CANopen cannot be used for this

"internal" communication channel, as there is no possibility of including the errors in

the SDO report.

8.6.1

Reading of a parameter:

1. Writing to sub-index (SDO Write)

Contents

2. Reading from sub-index (SDO Write)

Contents

After the writing of parameter number and data set per SDO Write, the corresponding

sub-index is read back with SDO Read.

In the reply in the reading from the sub-index, the frequency inverter states whether

the reading process was successful (ACK), then also supplying the required parameter

figure, or whether an error has occurred (NAK). If an error has occurred, a

corresponding error code is reported.
