4xxxxx Registers – Bypass
MODBUS addressing of 4xxxxx registers maps the drive’s parameters and other
values when using the drive device ID. The bypass’s parameters and other values
are mapped when using the bypass device ID.
Registers 400001 … 400099 - Bypass
The bypass maps its parameters and other data to the 4xxxxx holding registers as
follows:
400001...400099 map to bypass control and actual values. These registers are
descibed in the table below.
400267...465535 map to bypass parameters 0101...255255. Register addresses
that do not correspond to bypass parameters are invalid. If there is an attempt to
read or write outside the parameters addresses, the Modbus interface returns an
exception code to the controller.
Register addressing is done as follows: Use 400000 + 256 * (parameter group) +
parameter index.
For example: bypass parameter 0111 would be mapped to 400000 + 256 *
1 = 400267.
The following table summarizes the 4xxxxx bypass control registers
400001...400099:
Note: All parameters referenced are bypass parameters.
