138 • HRVS-DN Communication (ModBus Protocol)
_____________________________________________________________________________________________
16.8 Parameter Settings (4X References)
Parameter settings include all parameters that can be set manually. These parameters determine the modes
of operation of the HRVS-DN. They also set protections level. All parameters are word (two bytes)
parameters. The protocol supports both reading and modifying of (most of) these parameters.
Note: Use function 3 to read the setting parameters.
Any one of these parameters must be set with care. Inappropriate settings of some parameters can
result in damage to both the motor and the HRVS-DN.
The parameters have the following 4x references:
