Index low byte / Index high byte
Parameters and Lenze codes are selected with these two bytes according to the following
formula:
Index = 24575 − (Lenze code number + 2000 (parameter set − 1))
Example Calculation Low/high byteindex entries
Code C0012 (acceleration time) in
parameter set 1 is to be addressed. 24575 − 12 − 0 = 24563 = 0x5FF3 Index low byte = 0xF3
Index high byte = 0x5F
Code C0012 (acceleration time) in
parameter set 2 is to be addressed. An offset of "2000" is to be added
because of parameter set 2:
24575 − 12 − 2000 = 22563 = 0x5823 Index low byte = 0x23
Index high byte = 0x58
Subindex
Depending on the corresponding Lenze code, further subcodes may exist.
For all array codes, the value of the highest subindex can be read out via subindex 0.

Note!
ƒ Lenze parameters are mainly represented as data type FIX32 (32− bit value
with sign and four decimal positions). In order to obtain integer values, the
desired parameter value must be multiplied by 10000. (See "Attribute table"
in the documentation of the controller.)
ƒ The parameters C0135 and C0150 are transferred as bit code and without
factor.
