314 Parameters
Selects in which order 16-bit registers of 32-bit parameters
are transferred.
For each register, the first byte contains the high order byte
and the second byte contains the low order byte.
Changes to this parameter take effect after the control unit is
rebooted or the new settings validated by parameter
HI-LO
The first register contains the high order word, the second
contains the low order word.
0
LO-HI
The first register contains the low order word, the second
contains the high order word.
1
Defines the address in the drive which the Modbus master
accesses when it reads from or writes to the register address
corresponding to Modbus register 1 (400001).
The master defines the type of the data (input or output). The
value is transmitted in a Modbus frame consisting of two 16-
bit words. If the value is 16-bit, it is transmitted in the LSW
(least significant word). If the value is 32-bit, the subsequent
parameter is also reserved for it and must be set to
None
No mapping, register is always zero.
