Holding

Registers

Holding registers are used to read and write
drive parameters. They are standard Modbus
4x registers, 40001 through 4000F (see table
below). A number of read-out parameters are
provided in the 500 group of parameters to
allow detailed operational information read
through serial communications. A parameter
value is accessed by using the register number
that is 10 times its parameter number. For
example, parameter 201 is accessed through
register 2010. See the drive instruction manual
for valid parameter numbers and their
meanings.

For parameters with numeric data:

Refer to the Data Type table (on the following
page) for each parameter to determine if one
register (for 8 and 16-bit values) or two registers
(for 32-bit values) must be transferred.

Refer to the Conversion Index table (on the
following page) for each parameter, as shown
in the drive instruction manual, to properly
scale numeric values that are sent via
Modbus RTU.

For parameters that involve selecting from a
list, refer to the individual parameter description
in the drive instruction manual to determine
the numeric value associated with each
selection. This value is shown in brackets [ ] in
each parameter selection.

Parameters that involve alphanumeric data
can store up to 20 ASCII characters. Two
characters can be transferred in each register.
