Mapping table
The table below shows registers that the SINAMICS V20 converter supports. "R", "W", and
"R/W" in the "Access" column stand for read, write, and read/write respectively. Registers
with * are available only when the optional I/O Extension Module is connected.
HSW (speed setpoint), HIW (actual speed), STW (control word), and ZSW (status word)
refer to control data. For more information, see parameters r2018 and P2019 in Chapter
"Parameter list (Page 193)".
Register No.
