7.2 Modbus parameters
The following table 16 shows the Modbus parameters in the DC1 frequency
inverter.
RUN Indicates the access right during operation (FWD or REV)
- = No parameter change possible,
/ = Parameter change possible.
ro/rw Indicates the access right via the field bus
ro = Read only possible,
rw = Read and write possible.
