4xxxx Registers – Bypass
MODBUS addressing of 4xxxx 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 40001 … 40099 - Bypass
The bypass maps its parameters and other data to the 4xxxx holding registers as
follows:
40001...40099 map to bypass control and actual values. These registers are
descibed in the table below.
40101...49999 map to bypass parameters 0101...9999. 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.
