1)
For these registers, for S120 servo drives, parameters p1120 and p1121 are only available (and can only be parameter-
ized) with the extended setpoint channel.
2)
These registers are not supported for linear motors as the unit and value range differ from normal rotary drives.
3)
You can only access the technology controller parameters if the "Technology controller" function module is also activat-
ed.

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 the
se particular cases, the
maximum value that can be represented is displayed.
