2-180 ACH550 E-Clipse Bypass User’s Manual
Embedded fieldbus
For the Modbus protocol, drive parameters in group 53 report the parameter
mapping to 4xxxx Registers.
Except where restricted by the system, all parameters are available for both reading
and writing. The parameter writes are verified for the correct value, and for a valid
register addresses.
Note: Parameter writes through standard Modbus are always volatile i.e. modified
values are not automatically stored to permanent memory. Use bypass parameter
1615 PARAM. SAVE to save all altered values.
