40522 Output signal technology controller
For these registers, for SINAMICS servo drives, parameters p1120 and p1121 are only available (and can only be
1)
parameterized) with the extended setpoint channel.
These registers are not supported for linear motors as the unit and value range differ from normal rotary drives.
2)
The technology controller parameters can only be accessed if, in the STARTER project, also the "Technology controller"
3)
function module is activated.

Note
Limited value range
Modbus TCP registers have a maximum 16 bit width. The values of display parameters (r
parameters) cannot always be represented with 16 bits. In these particular cases, the
maximum value that can be represented is displayed.
