9.2.5.6 Parameter Values
Standard data types
Standard data types are int16, int32, uint8, uint16 and
uint32. They are stored as 4x registers (40001–4FFFF). The
parameters are read using function 03HEX "Read Holding
Registers." Parameters are written using the function 6HEX
"Preset Single Register" for 1 register (16 bits), and the
function 10 HEX "Preset Multiple Registers" for 2 registers
(32 bits). Readable sizes range from 1 register (16 bits) up
to 10 registers (20 characters).
Non standard data types
Non-standard data types are text strings and are stored as
4x registers (40001–4FFFF). The parameters are read using
function 03HEX "Read Holding Registers" and written using
function 10HEX "Preset Multiple Registers." Readable sizes
range from 1 register (2 characters) up to 10 registers (20
characters).

Explanation of the Control Bits
Bits 00/01
Bits 00 and 01 are used to choose between the four
reference values, which are pre-programmed in C-05 Multi-
step Frequency 1 - 8 according to the following table:

Bit 02, DC brake:
Bit 02 = ’0’ leads to DC braking and stop. Set braking
current and duration in B-01 DC Brake Current and B-02 DC
Braking Time. Bit 02 = ’1’ leads to ramping.
